To go with the beignets, more chicory coffee next time.
Tiana's beignets are magic and just make you feel wonderful.
Can't even spell that.
Tiana? Or beignets?
I dono, I think that's natures way of saying that maybe you doughnut want to do that again.
I have no idea what those words are 'about'.
When new things arise I don't hear about them.
I'm still working on tilapia
or latte
I did finally try a five dollar cup of coffee. Wasn't good.
lol 😂
Figured I'd ask this in Offtopic -- I'm doing some research into Automata (aka automaton, Karakuri puppets, whimsical machines, etc).
Although I'm perfectly happy exploring this on my own, I wanted to ask -- anyone familiar here with these? Any general resources you'd recommend, any "gold standards" to look at first before going to more obscure places?
For whimsical machines, I'm fond of Arthur Ganson's work and Tim Hunkin's work, and they have both built cam-based automata as well.

Looks fine to me -- I still see bare surface areas 😉
@dusty citrus that automata is awesome. Thanks for posting. I’m also trying to learn about mechanical design for automata so keep the ideas coming. So far I’ve only made 3D printed machines but am getting the itch toward metal machining.
One of the things i want to make in a future project is a laser cutter for thin sheet metal to do metal art like i posted the other day. Metal work is pretty fun to do
I've also looked into metal cutting, but more like plasma or milling, as (as far as I know) somewhat exotic lasers are required for laser cutting metal.
I haven’t done much research for it
My brother in law just purchased a laser cutter but its for larger steel than i need
Im just wanting to do sheet metal but his will cut up to 5/8” steel
Also wouldnt mind having a handheld unit and a cnc
Unless you plan to do a lot of that, it would be much cheaper to order parts you need from one of commercial laser-cutters such as https://www.oshcut.com/ than build your own laser cutter
I imagine it would im curious about cost tho. Looked into a glow forge at one point. 6000 is a tad much for me to drop
Can it do metals?? i thought glowforge is limited to wood and plastics
not that I recall
the glowforge's big selling point is about ease of use, not necessarily capability
according to this: https://all3dp.com/2/laser-cutting-metal-how-to-get-started/
to cut metal, you need a 300W laser - I would consider it way beyond price range of a hobbyist; realistically it would start at $20K, plus all the ventilation equipment. And I can't imagine a handheld unit of such power

I want to see an automata Philip Glass Orchestra ;)
He developed a mechanical hand that's very impressive.
@stoic mesa somewhere i thought i read that the glowforge could do thin metal. I must’ve misread it
Maybe i can do a cnc dremmel with a metal bit instead
Probably be alot cheaper and i can still go handheld
I think the Glowforge uses a fairly low power shortwave laser diode, so it can't even cut clear acrylic.
Yeah I haven’t done alot of research on it since im not willing to plop that much money down at this point

Your opinion in this survey is extremely helpful to me for the sake of a competition I am competing in.
Also madbodger i am gonna make a rotary shelf unit for my pantry in my house i can post a how i did it and show and tell if you wanted to see what i was thinkin for your tool ladder
I'd be interested in seeing that: perhaps it's not as complicated as I'm imagining.
that's the laser I would love to test.
Not exactly handheld, though.

Already deployed on the USS Ponce amphibious transport ship is the US Navy's first - in fact, the world's first - active laser weapon.
My company launched a nice art-game today. A small amount of joy in these dark times https://food.game
@late fulcrum the one im thinking of for you isnt bad at all. The one i am doing for my pantry will be a bit harder to do but i am thinking of doing rotary shelves on a rotary conveyor of sorts. The initial rotary shelves shouldn’t be that hard to do in themselves
Lmao I need to clean up
@tall pivot my dude, you if anyone needs to ask yourself, does this spark joy? ;)
the answer is of course, no but that aint relevant lady
@velvet pelican Buckminster Fuller invented a bookcase that is suspended from a ceiling; one of its features is that it rotates.
I assume he stabilizes the top section only and has some kind of bearing, joining a lower section to it.
A non-rotating version does not budge (at all) when fully loaded. Even though all the wires suspending it (exactly six wires) are anchored above the bookcase.
I've been wanting to make one but don't have a strong enough ceiling (and I rent).
You can imagine having 18 inches of clearance to the floor, and the free floor space underneath the bookcase, to appreciate its value. ;)

The present invention provides hanging storage compartment apparatus with various shelf levels adapted to be suspended by a plurality of tension lines from an overhead structure, such as a ceiling.
Date of Patent: Mar 22, 1983
Inventor: R. Buckminster Fuller (Philadelphia, PA)
@dusty citrus the way i was designing mine is more of a chain sprocket style with 1foot racks on a wheel system. Its not easy to describe tho. I imagine it would be a pretty long book to write without pictures
It'd be longer when described via Morse Code. ;)
-.-- --- ..- -.- -. --- .-- .-- .... .- - .. -- . .- -. ..--..
When i build mine I’ll post it. Its something you could make a stand-alone unit
I won't remember but that'd be very nice to see.
I hear memory is the second thing to go
;)
If I drink extra water I do a lot better.
When your memory starts to go, it's kind of fascinating because it reveals so much that was masked by the (better) functioning memory.
Ya see i have selective dimentia
Well today we have external memory (glancing at the Kindle Paperwhite in the room, here. ;)
We are cyborgs.
Indeed if you forget about the shelving stuff i can just link this conversation
Heh.
Someday it'll all be integrated into a blockchain.
Your grandkid will have it stored in their junk DNA.
Out of curiosity how old are ya nis?
six oh. ;)
Thats pretty young for memory loss to start in 😦
I didn't even drink, either.
People my age who drank a lot lost a lot.
I've written down many or even most stories, which helped to preserve them.
Thats good. Ive heard in the research for memory that aluminum is often the culprit unless your on medications that cause memory loss. My grandma had dimentia from both aluminum cookware and medications so her mind went quick. I only hope yours lasts a long while
Hope isn't a strategy. --Michael Osterholm
Maybe you can prove sudoku can sharpen the mind. I keep seeing things that say that lol
Riding a bicycle helps a lot.
I could see how having to remember balance could do that. Fourish months ago when i broke my ankle i never realized how hard the brain works to walk and balance. And since its a muscle i can see how it would help alot
Yeah it's huge.
Any breakdown in the system tends to expose details that were formerly hidden as they (previously) 'just worked'.
When I enter the property I deliberately get down to about 3 inches per second speed (almost a stand-still).
Then you see /Artistic Cycling/ and realize there's a further range you can reach (in perfect balance).
Ive seen people stop n balance in place alot
Also bmx riders do stuff on a single tire that I couldn’t dream of
Pt. II is:
https://www.youtube.com/watch?v=Wdwco_XqZ1A&t=2s
Which gets me more. ;)
I saw a recent helicopter shoot of the Megavalanche race .. couldn't believe the initial slope's pitch.
They're riding on a glacier (ice/snow).
Also the longboarders doing very fast speeds on a skateboard.
I cant watch those atm lol my internet is a potato
Alas, I can't ride a bicycle at all.
@late fulcrum is your equilibrium non functional? Or just physical limitations?
A little of each. I spent a bunch of my childhood in hospitals, so never gained the large-muscle coördination brain linkages.
Yeah, I remember! Now you can't help remembering!
The syntax coloring is a nice touch
Ahh well that’s unfortunate. I used to bmx alot as a kid but at least there are other fun things you can do. My personal favorite was sledding and now is snowboarding
Happily, tricycles are a thing.
tricycles are certainly a thing, especially in San Francisco: https://www.youtube.com/watch?v=-NA4PpCzP9g

@stoic mesa that where you live?

Ahh lol
At the time of launch of the first NTS-2 satellite (June 1977), which contained the first Cesium clock to be placed in orbit, there were some who doubted that relativistic effects were real. A frequency synthesizer was built into the satellite clock system so that after launch, if in fact the rate of the clock in its final orbit was that predicted by GR, then the synthesizer could be turned on bringing the clock to the coordinate rate necessary for operation. The atomic clock was first operated for about 20 days to measure its clock rate before turning on the synthesizer. The frequency measured during that interval was +442.5 parts in 10^12 faster than clocks on the ground; if left uncorrected this would have resulted in timing errors of about 38,000 nanoseconds per day. The difference between predicted and measured values of the frequency shift was only 3.97 parts in 10^12, well within the accuracy capabilities of the orbiting clock. This then gave about a 1% validation of the combined motional and gravitational shifts for a clock at 4.2 earth radii. http://www.leapsecond.com/history/Ashby-Relativity.htm
You remember?

My daughter drew it, I cut a two-color stencil and spray painted 10 copies in a first run printing. Feels good to start and finish something in one day, in contrast to software....
Multilayer stencils are the best @short pulsar
I made one that was a 5 layer one. Was a good solid brain strainer to make sure i was doing in right
I first read that and was thinking solder paste stencils, and wondering if there were 3D shaping of paste deployment by layered stencils and thinking "yeah, that would be a brain strainer" and then suddenly realizing that wasn't the subject at hand.
I've got a katazome project on my backlog that's going to involve way, way too many rice paste resist stencils
look at him though :3
So.... I guess that's a project that's hard to resist?
8/10 anything for my goodest boi laphicet
thats gonna be intense @tawny sonnet all them colors and details
yep, I've spent a few afternoons just picking apart the haori motifs
i did a 5 layer for a shasta base camp sticker
ill find a photo
was kinda like this but more colors
the small details are the worst part for stencils tho
bat'leth camp wants to borrow your logo
youd have to talk to mount shasta for that lol
i made a small wooden crate for a friend for her graduation with a bunch of snowboarding logos on it... the crate turned out well the best part of it was just buying a dummy grenade from the local surplus shop and running the grenade pin through the hasp... was fun to watch peoples faces when they realized there was a grenade hangin there
Fred Rogers pitched a grenade story to his boss, who didn't fall for it.
Maybe I posted this on the wrong channel....
@worn flicker I would recommend moving it to #help-with-projects

I don't think my older DSLR in HDMI mode is going to be a good alternate video camera if that's all the bigger the preview area is
@sick adder It's a long shot, but there might be third-party firmwares for your camera to get around such limitations.
helpful but with a groaner pun embedded
this mode might be good enough
there's no helping the pillar-boxing, it's a 3:2 camera and the video output is fixed at 16:9
but at least it's using all 1080 tall
can't seem to get rid of the focus-area box though
[Just realized what you meant by groaner pun -- sincerely, didn't even realize it or plan it that way]
@tawny sonnet I'm awaiting for updates on your work, it's always awesome to see! 😄
yes, magiclantern has a mode that makes all "bitmap overlays" disappear
@covert spire aww thank you 🙂 I've been off insta for my own sanity (I'm noping out of social media rn) but I can definitely send you pics if I get started on Laphicet! (at the moment I'm working on Pandoria's FX, which will mostly end up being posted here)
I had ordered Adafruit's SDR from digikey, but the product arrived doesn't seem like of Adafruit and the bill is made on Adafruit's product. Can anyone confirm if this belongs to Adafruit or not.
It's a 3rd-party product sold by Adafruit. The dongle is slightly different, but those pictures look pretty much like what I got directly from Adafruit some time ago.
Adafruit may have changed sourcing for equivalent product, or the supplier could have.
Cause I found this product on alibaba of 10$
It's possible the alibaba one is identical, or it could be internally different, no way to tell. At least with adafruit you know it's something adafruit tested, and shipping should be reasonably fast.
You ultimately get what you pay for -- reasonably fast & accurate shipping, something that's been curated by Adafruit -- reviewed, tested, and confirmed is a decent product. And you're supporting a US-based business.
I remember hearing stories from Ask an Engineer, where Adafruit bought dozens of various products -- to test them, see if they're any good, consistency between manufacturing runs, and being able to consistently & reliably source the products.
For me, it's worth a couple extra dollars to have someone do all that legwork for me. They endured all the sub-par products so I don't have to 🙂
On much of what's on alibaba, there seem to be a bunch of copycat items, where they are all copying each other, with similar looking items. Quality is likely a gamble on most of it. I looked there for a couple of minutes at cheap tablets, for one to use plugged in all the time as a camera monitor. The plus there besides price is they have removable batteries, so potentially I could run it without a battery: avoiding overcharging issues.
But I decided it wasn't worth the risk and outdated OS. Of course I didn't buy yet from the US store with 7" tablets running android 9 for $40 and now they are sold out and likely discontinued.
Not sure I'd buy a super cheap tablet from alibaba, good call, there are many $30 smart phones when purchused from china come preloaded with malware, recently someone figured out their phone was taking money out of their bank account via malware introduced somewhere in the supply china. This is not limited to phones but also network gear, computers, credit card processing equipment, etc real examples from mass sold equipment have been found. Its a fraction of electronics but is a thing to be aware of
yep thats why when I bought x18, I made new account just for it
nothing to buy
nothing to rob

I found an odd bit of kit abandoned on a bike trail. Looks to be some sort of controller. I figured I might get some use out of the housing at least.
Looks like an electroluminescent inverter. Probably takes a pair of AA cells and gives 100VAC or so.
Here is a pretty cool job opportunity NASA Flight Director https://www.usajobs.gov/GetJob/ViewDetails/577699400
Oh yeah I gotta take that one.
That job basically changed my entire life.. just seeing them at their jobs, via the television set.
I still look at the Moon, and think about those days. A lot.
All I did about it at the time was deliver the afternoon newspaper.
Growing up on the space coast, watching the Saturn launches, was very motivating. A space shuttle launch is amazing, but a Saturn V is incredible.
I've been fortunate to have had some opportunities to be the "operations director' for some of the activities on a few satellite projects. Just an inkling of what they do... but still a great experience.

Does anyone have any tricks for getting hands on IEEE specs or should I just drop the $99 as the internet seemingly wants me to? Im looking for 802.3bp-2016
Ieee standards should be well published and publicly available
IEEE standards are typically not public from what I have seen
Huh
If you want the standard, and go to the IEEE website, and go to download the PDF for this standard and many others, it asks for $99 per download, $75 if member
Okay, well I might know someone who has it
But I’m not sure they are able to share. I’ll ask though
Wait, I might be able to through my university
If you violate some agreement I can spend the money but that would be awesome if you can
Is there any specific part of it you are looking for?
Hm, I dont think I need all of it but Im unsure which parts I would need without looking at it, I am looking both for the data transmission, and the power over twisted pair
Though the IC I have selected does take care of the data part for me, I guess the power component is what Im more interested in
Oh I see
Would this be helpful at all?
http://www.ieee802.org/802_tutorials/2015-11/PoDL_tutorial_1115.pdf
It is a lot more helpful than the other slide show I went through, thanks, maybe this is enough but I have that funny feeling Im going to put it all together than realize I fundamentally misunderstood something. I think finding a PD ic and reading the datasheet might help
It is really outrageous that one has to pay for a standard.. not a tutorial or something like that, but a standards document.
Imagine if the standards like various internet RFC or Unicode were behind paywall
Indeed, I like RFCs system of just heres the PDF
lots of interesting information in this standard
Like how you can set specific bits for low power operation
Yeah, its really cool, I'm trying to get a SAMD51 to play nice since it's ethernet interface happens to be compatible with a transceiver IC I found

Lol
@sick adder that was an interesting note. I have worked with folks from almost all of those institutions.
I've continued trying to chase down this claim that "At the time of launch of the first NTS-2 satellite (June 1977), which contained the first Cesium clock to be placed in orbit, there were some who doubted that relativistic effects were real" but also these old papers just fascinate me
http://time.kinali.ch/ptti/1975papers/Vol 07_21.pdf A presentation and paper about the USSR's time standard was presented at the (US) PTTI in 1975
haha it was 6 HP cesium clocks
Thus general relativity saw one of the first major milestones in solidifying it as a foundational theory
Also atomic clocks
It also opened the door for deeper research into gravitational waves which helped lead us to imaging a black hole
Figure 2. [NASA] Laser Van
Ah the laser van
The Q&A at the end of http://time.kinali.ch/ptti/1978papers/Vol 10_23.pdf has all the scientists mad at all the other scientists who don't understand relativity 🙂
Still looking for a good deal on some kind of tablet, good screen size for the money, without OS version being years out of date. Don't care about battery life (removable battery and running without it would be a plus) only needs wifi, camera doesn't matter, etc. Seems like there would be some source of that, basic tablets that can run vanilla android, for people to use for homebrew things like camera monitoring and home automation.
How about an Amazon Fire 7? $50 new, or $40 refurbished.
I found Albert Einstein's Relativity in the public library, in 1979.
He says
8. ON THE IDEA OF TIME IN PHYSICS
Lightning has struck the rails on our railway embankment at two places A and B far distant from each other. I make the additional assertion that these two lightning flashes occurred simultaneously.
If I ask you whether there is sense in this statement, you will answer my question with a decided "Yes."
But if I now approach you with the request to explain to me the sense of the statement more precisely, you find after some consideration that the answer to this question is not so easy as it appears at first sight.
His style of explanation was very good, and useful at the high school graduate level of public eduction. ;)

Whereas Newton is elliptical from the get-go; Principia is fairly difficult reading.
@fathom relic Dell used to sell fairly inexpensive tablets. I think only Amazon Kindle Fire is still mainstream and very inexpensive, but that tops out near 7" diagonal (as did the Dells before them).
Outdated Android devices tend to work best if you zero them out and avoid most updated applications.
There are toolchains available (or at least there were, at one time) to do some development work.
Walmart did have a 7" onn tablet, store brand for $39.97 Android 9, with a couple Walmart apps pre installed. I was considering that one, but they've sold out in store and online. I may go with the 8 inch they have for $64
They also have a 10 inch for 79, and pro versions with at least more memory for stepped up prices

I think most people are bad at reading english cursive script anymore

they stopped teaching cursive in a lot of US schools about 15 years ago
My father in law spends a lot of time trying to track down old documents for genealogy and between the problems of language, digitization, and our facility at reading handwritten script it is often a challenge to know what you have
we spent one full evening debating whether someone's name was written Johann
only one time did I try to read a book in old french script & orthography .. fun time. If I recall correctly it was presented with the old script on one page and modern script on the facing page, so it wasn't that bad. https://upload.wikimedia.org/wikipedia/commons/8/81/Romant_de_la_Rose%2C_f._1%2C_ms._National_Library_of_Wales%2C_14th_century.png
and that's actually .. almost all perfectly readable
it's interesting how the larger space for the initial capital letter of every line is ruled
it's challenging sometimes going through old European church books, not only with handwriting varying from great to awful, but language changing over the years from Latin, to local, to German, depending on who was in charge at the time.
Does anyone have experience with the whole Rust for microcontrollers scene? (I’m wondering how the hardware and community support compares with CP or Arduino)
@willow ruin I mean to check it out. I'd love to hear your experience. I always appreciated what Rust is doing overall.
I tried on a RISC-V micro recently @willow ruin, I just tried a premade example but it was really easy to get started and I am currently learning rust on the desktop as much as I can so I can totally make the switch from C to rust on all my new embedded work.
Loving the language
Very neat

Reading handwriting for genealogy, even US English, in census pages written by someone paid to do it, can be difficult. Between the letters that look similar, unexpected abbreviations, and individual writing quirks, compounded by the variable level of preservation/quality of reporduction in what you are looking at. Then if the person reporting couldn't read/write, spellings and even names can change from document to document.
@dusty citrus I know you wre replying to someone but are you into rust?
@pearl vigil I haven't looked at rust enough to say much about it.
Ah, I've been using it recently and loving it, would be curious to see how you feel after dipping your toes in yourself

@proud harbor yeah. different culture thats all really
just use more tame words like heck
the project picture? seems just fine?
I live in an ultra conservative Asian city where freedom of expression isn't even there and you can be made to... disappear for showing dissent. But references to the mythical place bad people go to isn't considered offensive at all.
the project picture? seems just fine?
@real falcon
Nah I mean the mask with a skull on it.
i dont see that anywhere
i dont see that anywhere
@real falcon
A few lines above on this channel
oh that seems nothing
So yeah what's interesting to me is that in the polite society where I live, references to.... carnal knowledge (assuming that'd help me avoid some bots) via other words is considered vulgar and taboo. As is publicly holding hands. And showing dissent against the current... management (for the want of a better word). But references to the post-mortem netherworlds are fairly commonplace.
I've found it ridiculously hard to censor myself, seeing that I'm a rationalist. But hey, it's either that or my head lol. We've had people who openly preach irreligion be terminated and the perpetrators don't ever get touched.
https://www.jaycar.com.au/duinotech-lilypad-plus/p/XC3920 totally not a clone of the circuit playground classic...
But yeah, I'd love to see a list of banned words here, as well as an explanation of why they're banned and what groups of people (from amongst Adafruit customers I suppose - because you can never cover 100% of the world's superstitions) have a prejudice against said words.
Mostly out of intellectual curiosity.
i think its mainly due to people coming in here and cursing everyone
seem problem have stopped but we used to get so amny annoying people
so automating removal of those was nice
Aah.
So it isn't about American / New Yorker values around religious sensibilities then?
not very likely yeah
Because unless I've been living under a rock, that's the bastion of liberalism pretty much.
And it'd feel a bit like discovering that Metallica were secretly a K-Pop band.
Staying on the theme of #general-chat , I recommend this book to anyone who finds certain words offensive. The audiobook version is a BIG treat. https://www.amazon.com/Etymologicon-Circular-Through-Connections-Language/dp/0425260798/
@proud harbor we don't have a published list of banned words for several reasons including just practical reasons such as the fact that bad actors would use them to evade automated moderation.
But the general rule is be respectful and realize that this a forum that has young folks in it.
It's not about specific words, it's about a culture of respect for one another. You can read more about that in #code-of-conduct.
But the general rule is be respectful and realize that this a forum that has young folks in it.
@burnt wave
That's fair. But I'd reckon a simple word banlist doesn't necessarily capture whether a sentence was respectful and considerate.
For instance, I'd used a term used to refer to a mythological place evil people go to post mortem that a lot of people seem to believe exists to describe the pain involved in hand-soldering small connections on the backside of a cheap perfboard. Unless my definition of disrespectful differs from yours, I wouldn't consider this offensive at all, since the disrespect was directed towards my own soldering capabilities.
However, not all of Adafruit's customers are North Americans. Some of us might posses different cultural sensibilities. In such scenarios, it's best to explicitly ask and clarify, than make assumptions.
We understand. Not all of the moderators are North American. Unless it's a clear case or a someone who repeatedly oversteps, we generally give warnings.
@burnt wave Just so I'm clear though - the word I described was banned because it was used in a rude fashion while talking to someone, and not due to religious sensibilities, correct? Because stuff I make often tend to feature symbols of death, occult, horror, and gore, for the lulz. I'd probably need to avoid sharing them if it's religious sensibilities that are being offended.
some of us despite being older find certain types of speech distastefull too
it may be largely a US thing, but that particular word is one of the many that younglings here are discouraged from saying, and since this is a place with many younglings, we try to keep the environment such that adults don't stop their kids from learning here
I'm not sure what word you used or the context, but religion isn't really a consideration. It's just about using respectful language and not using language that would be inappropriate to an audience with broad age ranges.
Again, you can refer to #code-of-conduct for our conduct guidelines.
@umbral phoenix Aah interesting!

I'm an actual witch so puritanical ideals don't really factor into my moderation actions. 🧙♀️
one thing i find annoying more than anything is when someone swears so much their speech becomes completly unintelligable and it just makes them sound dumb to me

I read it a couple more times. Like I said before, due to cultural differences, what one person considers harmless might be offensive to someone else. But I suppose like all businesses, adafruit defaults to considering the sensibilities of people who spend the most money because that's what pays salaries.
Only a handful of our moderators are Adafruit employees. I am not.

@burnt wave
But this discord is owned and maintained by Adafruit, isn't it?
I would say that it's maintained largely by the community itself.
And is the community (and thus the discord) independent of the ideals, values, and politics expressed by the company?
I'm really not sure what you're getting at.

Just clarifying if this is or isn't the place to ask questions to adafruit the business.
You should submit a support request to them if you want to ask Adafruit themselves business related questions
This is a community forum.

yo guys, question
would battlefront 2 run on an 940M 2 gigs on low?
need confirmation ASAP before the sales are over

@pearl vigil stumbled across a bookmark in my browser:
oh man I just need to vent for a second. I ordered a phone case from google. Fedex damaged it and sent the damaged item back to google; I never saw it. Got e-mail from google: The shipment was returned to them, so I need to contact them to receive a refund. "contact us" link in the e-mail did not go to a page to contact them, it went to a general help page on google. It's sorted now but ARGH they created a bad customer experience for no reason.
(the customer support rep told me I didn't need to contact them and that I would have gotten a refund anyway, but what I wanted was my item!)
anyway that's all
That is annoying. Fortunately, when my damaged lawn cart showed up, I was home and the delivery person asked me if I wanted to just return it or accept the shipment and they'd document the issue.

@weary fiber Sorry to hear, get well soon! (Do the VFDs blind you too?)
Hello there, my name is Aabhas Mathur. I am a part of a startup called NATE health and we are looking for an app developer in the US. If you are interested or know someone who might be interested then do let me know
@tawdry turtle adafruit operates a "jobs board", it's a more appropriate place to reach people in the Adafruit community who are looking for work. Check it out and consider putting up a listing. https://jobs.adafruit.com/
Find maker jobs in 3D and CAD, Art, Design, Education, Embedded Development, Engineering, Fabrication, Marketing and Communications, and Web Development
talking about bad support system, i found a bug on discord, but I can't even report it because they quiz people trying to make a report on how to make a proper bug report.
annoying for sure

Is it just a myth that excessive alcohol makes you forget things before drinking? Like, I’ll see a character drink too much, and in the next morning they don’t remember some things that happened before they started drinking. It makes no sense to me, doesn’t being drunk simply hinder your ability to make memories? I wouldn’t expect it to like, erase memories :/
Cool thing here: https://en.m.wikipedia.org/wiki/Kerr_effect
The Kerr effect, also called the quadratic electro-optic (QEO) effect, is a change in the refractive index of a material in response to an applied electric field. The Kerr effect is distinct from the Pockels effect in that the induced index change is directly proportional to t...
@hasty quarry The people I know who drank much of their lives don't do well in remembering the past, in comparison with tea-totalers (even when the tea-totalers drank on occasion).
I think it takes a little time for short-term memory to migrate into long-term memory, so alcohol might interfere with that process and cause essentially a "cache flush" of the stuff from earlier in the evening.
Ah
sleep is also thought to be a factor in transfer from short to long, and alcohol can affect quality of sleep
Take a look at the Moon tonight, bright Mars is right next to it
@jovial swift at 2 am it should be nice n bright
i saw mars yesterday just before going to bed was pretty cool
Mars is very close to the moon tonight
the night i saw it it was nowhere near the moon lol
a good demo of how much the moon moves in the sky every night, Mars barely moved
bummer, astronomy is a hobby of mine, I rarely see a planet so close to the moon
ohh there is the moon rollin through the clouds a little here and there
but its behind the trees and not high in the sky
hopefully in an hour you'll get a break in the clouds
haha in an hour ill hopefully be asleep.... if this youngin here will let me
I saw a bright object near the moon so I fired up a star map app on my phone which informed me it was Mars. Neat sight.
How do those automatic telescopes work
Those ones you calibrate, and command to point at anything perfectly
Some complex trigonometry or something?
Mars is on the increase in brightness. The moon was way above the western horizon this morning, well after daybreak, and Mars was right next to it (though I couldn't see it in daylight ;)
@hasty quarry They use an equatorial mount.
All you need to do is aim the system at Polaris.
There might be some other minor procedures to get everything the way the onboard computer wants it, but alignment of an equatorial mount to the North Star is critical to its use.
The (Northern) sky appears to rotate, counter-clockwise, around the North Star (Polaris).
That is the observer effect of living on a planet that rotates - something in its night sky will appear not to move; the rest of the night sky will appear to revolve around that point.
Yeah, it is. ;)
Your latitude above the equator is the same angle as Polaris is, above your horizon. Exactly.
What does the telescope do if the star is below the horizon
Does it just go "Nope, can't see that"
I would guess they have a setup for the southern hemisphere.
How does/would it even know that
I don't know if they bother to actually use machine vision (I doubt it; not at entry price points, I'd guess).
Pretty sure the electronic setting circles rely on human input to set it up for the first slew.
Then the computer justs follows a sky-shaped grid.
H.L. Rey wrote Curious George books.
He also did a very (very) good introduction on observational astronomy, aimed at a younger audience.

https://en.wikipedia.org/wiki/H._A._Rey
Rey uses the analogy of the inside of an umbrella.
You stand outside and point your opened umbrella to the North Star, then twirl the umbrella counter-clockwise (so that the top edge moves to the left, as time passes).
Then just imagine you've drawn the big dipper in chalk, on the inside of the umbrella.
When you get used to those orientations, you'll note that indeed, objects rise in the east and set in the west.
I still haven't figured out why Mahjong gets this basic fact about the world, wrong.
Machine vision telescope alignment accessories can be had for US$390 https://www.highpointscientific.com/celestron-starsense-auto-telescope-alignment-accessory-94005
Well, that's something to reflect on.
I hadn't appreciated the scope of that, before.
Discord reminds me of Winky Dink
Mom hated Winky Dink, we always forgot to use the magic screen 🙂
;)
Mars is at 88 azimuth (east) altitude 9 degrees at the moment. Stars visible overhead in NW Connecticut.
I'd say it's showtime.
@dusty citrus
char tst[] = "\n";
void setup() {
// put your setup code here, to run once:
Serial.begin(9600);
}
void loop() {
// put your main code here, to run repeatedly:
Serial.println(sizeof(tst));
delay(10000);
}
Returns 2, one for the single ascii byte 0x0a which is a newline, the other for the null char. The \ before the n tells the compiler the char after is not the letter but rather an identifier similar to \" tells the compiler the " is a part of the char array not the end of your declaration
It has no idea that 0x0a is special to humans.
Also, I like your desktop, is it tiling?
There's a name for it I just call it an escaped .. thing.
That's just fluxbox. I think.
Oh yep, very nice, I havnt played with fluxbox before, I like trying niche window managers 😜
Yeah the binary is calle fluxbox - there's more than one variant and I didn't remember which one I run.
Fluxbox gives me two things I depend on - oversized windows, and easy to access desktops.
Yeah, very nice, I like the tabbing, Im an i3 man myself
Control + Fn accesses the first 12 workspaces (I have 16 programmed) and Ctrl+Alt+<arrow_key> moves to the previous or next workspace.
Alt+0 (zero) makes a terminal look like the Virtual Console (all window decorations go away; entire screen is that xterm).
Well Im sure that lets you be quite productive. Looking at it looks really customizable. Does your config go into a config file you can just backup and paste onto any new computer?
Sure, yeah, but it's good out of the box; I usually update it when I find the time.
it's all in .fluxbox (/home/foo/.fluxbox).
The harder one (by far) is the style sheet for Geany. ;)
Yeah I have a similar setup with my i3 in ~/.config/i3
If I want to watch a video at an arbitrary zoom level, I can do it in fluxbox.
I just resize the YouTube window to an absurd dimension.
Oh thats cool, I dont have that
Yeah, ALT+Left_Mouse_Button dragged moves a window in Fluxbox.
You can also set the 'magnet' thing to zero so that the windows don't resist placement to an individual pixel column and row.w
Otherwise they kind of snap into place.
Just out of curiosity what do you run this atop of?
$ ag snap init
34:session.screen0.edgeSnapThreshold: 0
Fluxbox is a window manager. You can start Xorg with or without a window manager present. It doesn't care.
I was just wondering what your linux flavor of choice was
Debian AMD64 is the base substrate (Dell Optiplex 7xx)
This is real everyday Debian.
Nice, cant go wrong with debian for sure
Even Debian is starting to do things I don't approve of. ;)
Oh?
I had to figure out unattended-upgrades.service on my own. ;)
Then I still saw apt doing stuff I didn't authorize.
Huh, thats odd... I wouldnt think debian would have done that crap. I hate it when you go to do something and apt is locked because of some background thing
The main reason I don't run, say, Ubuntu more, is that it does too many things I have no awareness of.
I think apt just fetched something harmless; I don't think it updated to a new .deb.
Or just you know, doing something for me in the background in general. And I agree, I dislike ubuntu and wont touch it, they lost me after the amazon thing
But it was in addition to unattended-upgrades.service having already been disabled.
Yep, Im liking arch simply for the pacman package manager, its soo good especially for embedded work oddly.
Ill apt install a niche compiler and it wont be there, or a dev package, but you can bet pacman has it
$ sudo systemctl status unattended-upgrades.service
[sudo] password for nis:
● unattended-upgrades.service - Unattended Upgrades Shutdown

The purpose of unattended-upgrades is to keep the computer current with the latest security (and other) updates automatically.
I see why they are doing it... but....
I should probably at least try arch. I use their documentation from time to time.
$ sudo apt-get update
$ sudo apt-get upgrade
```I still get to say yes or no to everything, doing it like that.
Yes, I guess there were probably issues with debian servers not being maintained and it was becoming an issue. I dont mind fetching in the background so you can SSH in and see if you have any packages missing but unattended-upgrades.service will just update it looks like
I like the control
Oh and Ive also been playing with alpine linux on the thinkpad I test niche software on
You know, the docker container OS
I've run Linux for far too long; it gets to be offensive when 'they changed it on me'. Life is just that way: you get used to one way of doing things.
I can see that, but I mean, upgrading software in the background is a little different because it actually affects your user space
Raise your hand if you think windows update is great, anyone?
workspace, blank slate, one each
Ahhhh, r/unixporn
There was a BBS program called GIGO (garbage in garbage out) that was windowed. In text only.
It used gold on red for a lot of the menus.
Huh, thats interesting, I wasnt aware you could color BBSs but that makes sense, bit before my time
Basically the equivalent of an ncurses application.
Yeah, makes sense.
I found digging for interesting icons was annoying so I picked out these and copy them to my home directory.
Lol, there is a little mismatch but Im finding it charming
config firefox chromium geany xosv sylpheed geeqie galculator
fbreader qpdf vlc uxterm gedit sound xterm nautilus
xosv basically monitors the network for traffic. uxterm I never use but it's probably for a different font size. sound isn't working. nautilus is the file manager. I think it's called nautilus.
exec /usr/bin/nautilus "$@" >/dev/null 2>&1 &
I didn't want whatever usually goes along with nautilus; it's a fish out of water the way I use it.
95 percent of what people do with nautilus I do at the command line.
I will use it whenever I plug into something on the USB bus that offers storage, to mount that storage device.
something about gvfs filesystem
I like the file extraction, I always just blank on what the right flags are for the tar tool for different formats
Lol, I havnt used zcat before, learn something new every day. Nice talking to you, I gotta go to bed, have a good night
@tardy badger does that FPGA board have enough gates to make a basic RISC-V cpu?
That’s a good question
I was thinking of cubesats and was wondering if a concept would work
Maybe not with the ICE5LP4K
It is 4K logic cells which seems to be about 20K short of being within reason
I figured, was a curious question
@tardy badger also put your code on github in a way they can't miss it. /your_web
That isn’t to say I could jam a 30K cell lattice fpga on a feather
I saw someone put a Zynq on a feather lol
I could probably make a $45-$50 retail FPGa feather that could run a risc-v architecture
That'd be neat, also, you mentioned an SPI programmer, is there an open source tool for that, and could I run it on a Pi? I love using Pis as programmers
That you know of anyways
Right now that ICE40 feather can be programmed using a pi pretty easily
At least for the EC5
But it’s the same tool chain
Neato, if you get around to the bigger FPGA be sure to @ me
For what I want I think Ill need 2
Cool cool! I’ve been eyeing up my next lattice project so probably by the end of the year
I need to find a decent pick n place
Or a stabilizer bar for when I pick n place my components 😂
I can do 0402 pretty confidently
Sounds good, I got so much on my plate I wont be able to start thinking about this until then. Nice, I'm getting into 0201 myself 😜
I don’t know if my eyes are good enough for 0201 😂
Yeah, we'll see if mine are soon enough
I have a massive magnifying lamp
Nice, I need to bill my work for one
Been thinking of setting up a TV with a pi and USB microscope I have as well
I’m getting new glasses soon so hopefully my eyes sight will improve
I’ve not got new ones in like... 5 years 😝
Been too poor to get new ones until recently
I can understand, lol, I enjoy a new pair myself every few years
Luckily once I get a job post graduation I’ll have insurance and can afford to go every year like I need to
My wife has coke bottle lenses so she should be going more often than she does too
You mean like plastic lenses?
Like thick thick lenses
Ah got it 😆 like looking through a coke bottle
Sounds it, glasses are expensive when you dont need that
yeah. $80 just so they can tell me how bad my eyes are
Indeed, send thx note to luxottica for the other costs
what's worse, is I have double vision and I should have two pairs of glasses. one for up close reading/computer stuff and one for driving and normal use.
Yeah, my gf is the same way, two is twice as expensive
nothing like reading something and the sentence splitting off into oblivion
Could get bifocals but those are a huge pain
i wish bifocals would fix my double vision
Oh nevermind, whole 'nother issue
I have a friend who was sighted and now is legally blind. Never saw it coming even by her 40th birthday.
That wont help much
you don't say @dusty citrus haha
All I can say is, practice all your skills while you have vision. ;)
that's the goal
I've known a ham all my adult life who was blind when I first met her.
Replace your eyeballs with image sensors using your FPGA boards
I've been touch-typing since 1987 or earlier.
That'll make a big difference if I have even worse vision issues than I do now.
Touch typing is the way to do it vision issues or no vision issues
I also have Linux setup to maximize vision assist.
Extra large fonts on everything I can.
I can go pretty big on them fonts. ;)
She says she can't even see that on her teevee.
macular degeneration affects the centre of vision.
@pearl vigil looks like some people implemented a 32bit risc-v processor on a 4K element FPGA
so it might be pushing it, but you might be able to squeeze a basic 32bit risc-v architecture cpu on the ICE5LP4K
Very impressive, but I also need space for an extra set of registers, some bit of CRC logic, and a serial memory controller
granted these are microsemi ones.. but maybe an 8K cell might be enough space for ya
Yeah that would probably work, i need the simplist thing I can get my hands on
https://www.digikey.com/product-detail/en/lattice-semiconductor-corporation/LFXP2-8E-5TN144I/220-1115-ND/2641916 it'd be pushing it to put this on a feather lol
Order Lattice Semiconductor Corporation LFXP2-8E-5TN144I (220-1115-ND) at DigiKey. Check stock and pricing, view product specifications, and order online.
but i feel it would be possible since there is no thermal pad to deal with
just would need to be on the top left corner lol
If I did BGA, it might be possible if I found one with the right pitch and whatnot
Yeah, maybe for now I just look into dev boards but they be pricey
indeed
I'm going to be chipping away at it regardless so I'll let you know what I come up with
This very powerful and versatile chip consists of an 18x8 array of architecturally
identical, independent, complete F18A computers, or nodes, each of which operates
asynchronously. Each computer is capable of performing a basic ALU instruction in 1.5
nanoseconds for an energy cost on the order of 7 picojoules. Nothing else available
today comes close to that winning combination. Twenty-two of the computers on the
edges of the array have one or more I/O pins and one of several classes of circuitry
associated with them, as illustrated below.
The chip itself is 20 bux a pop.
seekrit budget price page:

Here's the Schmartboard work-around:
https://schmartboard.com/schmartboard-ez-qfn-88-pins-0-4mm-pitch-2-x-2-grid-bundled-with-a-greenarrays-ga144-ic-202-0048-02/
I'm not sure I could handle having 144 ALU's to ..organize into a task.
Just spray 'em with smart glue, go to bed, and see what they come up with, on their own, in the morning.
Ooooh, I just realized that, inside of my geekroom, I've got a stabilizer platform for paintery that would probably make soldering more stable as well, @tardy badger
I've seen a number of people do that. Seems to work well, especially for placing the dust sized components these boards require anymore
not exactly sure how a pizza crumb sized capacitor can hold 10uF of charge but the physics is lost on me at that point. It starts merging into witch craft at that point.
That is interesting @dusty citrus, Ive been seeing more chips like this but in the datacenter not for embedded
Ohh yay we are supposed to get 65mph sustained winds tonight
I guess you are a little blown away by the forecast then.
@pearl vigil That GA-144 chip is the brainchild of Chuck Moore himself.
I got a table top coming from Amazon - 1.125" thick laminate, 36x36".
Seven bux. Shipped. ;)
For three weeks I had a credit, so it looked like they were paying me eight dollars to take the table top off of their hands. Shipped from Arizona, to Connecticut.
It's a 30 lb. slab of wood. ;)
Lists for $61 and priced hasn't budged 2 percent since I bought mine (Amazon warehouse).
Maybe it's worth like $41 or $51 and that's how they can fund the free shipping.
@dusty citrus thats good, were you who I was talking about forth with? And nice, when I need a table top I grab a solid flat wood door and people give em away 😉
I talk about Forth a lot so probably. ;)
I got these legs for the table .. Lorell Activity table legs.
They're about $65 shipped. Adjustable in height.
Oh neat, do you have to adjust a screw?
Yeah it's a big set screw.
Like a T-shaped nut pressed into the steel leg.
I would say it'd take more than 400 lb to shear it.
They also have a children's length for really low tables.
Yeah, this looks exactly like what the legs of the tables at my old public schools looked like
Yeah it's basically bicycle handlebar stock and they whack it hard with a press that punches the holes thru it on one side, and deform the cyl. to a D shape.
Then they chrome it. or maybe they chrome it prior.
The permanent tube looks to be about 12" long.
Neato, didnt know you could just buy them but makes sense
Well, they want to sell you multiple table tops.
I have no idea why they offer the legs separately.
Lol, are they publically traded?
Since I'm buying the table top from a competitor.
I don't know. S.P. Richards, in Atlanta, Georgia, for the manufacture.
Of course they're so obscenely priced, it feels like a deal when office depot sells me a set for $49 plus shipping added onto that.
The end goal is a 27" table height for Mahjong. ;)
Very nice, never played, sounds like a good setup
I just want to get a little bit comfortable with the physical aspects of game play, so that it disappears from the attention when playing face to face (after the end of the world is cancelled due to lack of participation, that is).
I think we're going to .. skip .. that whole 'old folks home' thing..
I mean, that is really too bad.
Never ever again will a younger person have a valid argument to ship the old folks off to the old folks home.
That's gone.
Jupiter is up and transiting, 25 degrees above the south horizon, now.
Mars is near rising.
Mars will be 3 degrees above the eastern horizon, at 01:30 UTC (9:30 p.m. in New York).
Jupiter is transiting what?
the meridian
alas it's too low from my location, but Mars is positioned perfectly!
lol
A transit is when the meridian that the star is on, is due south (highest point in the sky; 'centered' on the location).
When the Sun transits we call that Noon.
That's not quite it .. oops.
The local meridian is an imaginary line between the North Pole and the South pole, that passes directly overhead at your location.
In Connecticut, that's 73 West longitude.
When the star or planet crosses my meridian, that's a transit.
At that point it is as high in the sky (altitude) as it gets on a given day, and is also due South.
(for the southern sky)(
i think madbodger was hoping the moon would transit in front of Jupiter
Moon was a good 10 degrees separated from Mars this morning.
amazing to see how "fast" the moon moves in the sky compared to the background
soon Mars will go retrograde (and epicycles will be reborn 🙂 )
Mars is 94 azimuth 15 altitude in NW Connecticut at the moment.
same here, northern NJ
oh! i didn't think it started for a few days yet
20 degrees of azimuth now separate the Moon and Mars.
No the retrograde happens in .. Octoberish I think.
I don't think we'll get any kids for Halloween but Mars should be close to the Moon again then
Roughly Nov 14th, give or take a week.
Yeah Halloween takes on a whole new meaning. ;)
Mars reverses in Pisces near the Vernal Equinox point on the Ecliptic.
That's the astronomy Pisces. ;)
i always wonder how strong mead was for folks to have imagined some constellations...
28th to 29th October, Mars passes near the Moon, which will be waxing or Full; Last Quarter begins around 2 Nov.
oh good, I'll get out the camera for that!
My acquiantance asked about the comet.
It was really hard to explain why there were real limits in enjoying that comet.
(I never did see it)
It wasn't like Hale-Bopp but I was able to observe it visually
I've only seen one comet. Was a smudge in city lights, but pretty high overhead, around 1997 or so?
that was Hale-Bopp, very bright in the country side
I knew it at the time but just don't remember. I remember where I was (out back on the premises of the building I lived in).
I bought a 'Comet Catcher' that Celestron made for .. the big one (Halley's maybe).
It was in a camera shop on the glass counter.
i barely could see it at all. tacoma skies is unfriendly
Halleys was a dud last time around
I bought the telescope a few years later. ;)
and I'll need significant advances in medicine to see it next time 🙂
I still have the mount (about 12" tall or so) but ditched the scope (3" aperture refracting).
my first scope was a Sears 3" refractor, good for solar system objects (when you are 9 or 10 years old)
Yeah a friend showed me Beltegeuse (Sp) Betelgeuse when I was about 8.
so much hubbub lately in the press - "Betelgeuse about to go supernova!"
Well it did fade a lot.
and it will, Tuesday (or a million years from Tuesday)
When it came back it came back good. ;)
That's a big process happening that we'd notice it on that time frame.
If it were farther away it'd be like missing watching a space shuttle launch on TV (with a casual 'so what').
it would be spectacular to have such a close nova ( a new star in the sky in daylight)
Until February, Betelgeuse was a big big existential reflector. ;)
Now it's like betel what.
ya never see the one that gets ya...
Kids born 10 years after Betelgeuse was visibly nova, would take it in stride as 'of COURSE it's up there, can't you SEE THAT?'
lol
it saddens me that for so many ppl the moon landings are only history, not something they watched live
Hey, I got to watch not one but two space shuttles blow up on live TV.
Well, yeah, we saw something just stunning with that.
not the same feeling at all @burnt tendon ...
;) ya think. ;)
It's difficult to imagine the uninitiated experience becoming fact of experience.
Projects Gemini and Apollo were non-trivial.
Al Worden said the space suit wouldn't let him move his limbs.
my dad worked at White Sands in the 50's, he said they popped champagne if a test DIDN't hit the blockhouse
He couldn't bend his elbow at all. They hadn't yet thought that through, and he was in freefall, outside the capsule, testing it. ;)
somebody say NASA stole a decade from the 21st century in the 60's, i believe it
amazing no one was lost in space in the early days
;)
I watched the moon launches (with my own eyes) and the landings (via TV). While a space shuttle launch is amazing, a Saturn V is incredible
If it was up to Lost in Space it'd still be 40 foot cyclops and vegetable men.
IDAK
TV dinner foil space suits.
you saw the launches live madbodger?
Yes. An advantage to growing up on the space coast.
that must have been teeth rattling
Indeed. We were a few miles away, so it would launch in silence, then the SOUND would arrive a few seconds later.
i bet, always wanted to see a live launch (of anything) but not yet for me
Sometimes a jet aircraft engine will be tested on the ground. It's very very loud.
but i bet it's missing a certain element of bass that a rocket has
;)
oh, i saw a discussion of red shift earlier, isn't the frequency change of light due to space itself getting bigger, making the wavelength longer?
I guess one thing you can say about astronauts is, whenever they have to head home, they have to sing the blues.
you think they are sad to leave for home?
The simple redshift explanation works like doppler.
No, it's a blueshift pun.
so all objects speed away causing the shift?
There is no center so everything seems to be receding from everything else no matter where you are located.
the muffin analogy
I was going to type that there are regions receding faster than the speed of light but I don't remember the quote.
ah well, work is creeping up soon, happy hacking all!
;)
Is there some kind of theorem which states that none of the break-apart headers will be the length you need, and that 1s and 2s accumulate without bound?
I'm not above putting a row of 1s and 2s in a solderless breadboard and using them as a longer one. However, plenty of my boards seem to have 2-pin headers, so they probably accumulate for me like they do for you.
I got 4 spare header pins with my MCP2221A board but I need some for a project later so this is okay

Min wage here is $7.25
I really want my electrical engineering degree, but HECK they ain't making it easy
Ouch. I wonder if "building a generator" would be a useful extra credit lab.
@weary fiber where is that region?
North Salt Lake-- lots of people have had trees ripped out of their yards 'round here unfortunately :/
is that a 3-credit class at $300/credit? are you out of state? that's utterly outrageous, especially in a state with such horrid min.wage
You know, Mustangs are okay cars. And I thought, surely no one will ruin it with horrible wheels. I was wrong. Very wrong.
I bet you it has gimpy stock brakes too. bigger wheels need bigger brakes.

2 ping
so good!
Impressive. With 2 ping you must live within like 100 miles of the server.
server is .4 miles from my house!
@jovial swift well i hope my house survives the fire so i can do a show and tell on it.... got evacuated today winds are stupidly high still
oh no! fires nearby?
😨
Yup they started yesterday with all the wind and its blowing up the area possibly gonna burn through my zone too
You can look up estacada Oregon thats the city south of us and its a wreck all evacuated yesterday and it burned through there and going south. We are north of it by around 10-15 miles all it takes is a small shift in wind and then we will be in the wake of it
Best of luck, i looked up the town homepage, warning sounded dire. Hope for winds from the North!
hoping for calm no lightning filled rain storms
Anyone familiar with those vintage CRT testers and know if there's any real difference between the nixie and radio tube testers and the monitor tube testers, on a basic level? Controlling deflection plates would be hard with one not meant for monitor tubes of course..
Hmm, the vintage CRT tester I have doesn't seem to support deflection (electrostatic nor magnetic), just exercises the electron gun. It does have some cathode reactivation functions that ordinary receiver tubes generally don't.
Hmm. I guess I can control deflection by other means, or wait for the right one to pop up..
No, I should get a proper one.
The one I got an offer for is very limited.
And in bad condition
Sorry soviet tubes, next time :D
Cheers
Electrostatic deflection is fairly straightforward, a couple of high voltage transistors in a differential pair will do the job.
Yeah, there's is plenty of schematics/open source drivers for >5" deflection ones, but I have few yolk deflected ones as well
Almost had the perfect tester for both, but it got sniped :)
The magnetic ones are a little trickier, you basically use an op-amp with transistor booster and a current sensing resistor in the feedback loop for those.
I saw a good writeup on it, let me dig up the URL
Oh nice!
Ah, this one, and the earlier articles in the series that it references http://tubetime.us/index.php/2015/06/27/crt-magnetic-deflection-driver-design/
It's Eric Schlaepfer's blog, he's behind a bunch of intriguing CRT projects as well as the MonSter 6502 and several other "dis-integrated" circuits.
you know of that project where guy made really tiny crt
you know wheres it at? never could find it for long while lol
crt was 1/4 inch diameter heh
I can think of a couple of possibilities. One was a pretty much completely hand-made field emission type CRT.
The other was a teeny video monitor made out of a camcorder viewfinder.
former yeah i dont count those already crt ones 🙂
A search for "DIY CRT" on youtube brings up probably the one you're looking for in the first several results.
Eigenbau Kathodenstrahlröhre - homemade crt tube nach Art von http://www.sparkbangbuzz.com/crt/crt6.htm Mit einfacher Ablenkung des Elektronenstrahls mittels Spule bei 50Hz.

I have a real fondness for CRTs...
It's called "Vectrex", they're neat consoles
And from that picture you might (correctly) guess that I'm building a vector unit.
A follow-on to this vector generator
that is cool
Well... good luck getting the whole thing on line...
🙂 nice
@late fulcrum Much appreciated, I'll check it all out :D
Vertex displays just... draw vertexes instead of scanning right?
Just the mode of control that differs?
I have an ancient tube, the driver is beyond any form of repair and there is no replacement places to put the tube anymore. Conversion possibilities?
lind conceptally you could turn crt tv into vector one or vector screen to crt tv but takes some work
No knows operating voltage values either so, it's probably quite a bit of some work
Flyback seems to be good tho.
Saw one conversion that started out by rewinding the yolk
CRTs just feel like such forgotten things, especially when looking for specifics, hehe.
yeah
china bought last crt company, found out they cant make em
possible art for fancier screens is lost
Figuring out the voltages isn't really too tough, most tubes are fairly similar.
I got this fun red-phosphor CRT from a discarded projection TV, I worked out the pinout by examining the connections through the glass, and the heater voltage turns out to be the standard 6.3V.
I'm also not above 3D printing CRT sockets when needed
Well, I will have to give it a go
After some of the more space demanding projects are not 95% done on my table.
Hehe
Be warned, it's possible to get possibly overly fond of CRTs...
It is fun, however
Inspired by the Jim Williams app notes and TubeTime articles, I've started designing my own CRT power supplies around CCFL inverters
Got a handful of these in the storage
mixed colors
and this real lovely one, including board which is angled 45 degrees and mirrored
also in a box so, not sure if I'll find a pic
I think the И ones are green phosphor, but they make a few others. That's a nice PDA electrostatic unit.
That sounds like a neat unit. Some Watchman style CRTs, but larger (4" or so) showed up on the surplus market a few years back. They're interesting, electrostatic deflection in one axis and magnetic in the other.
Nice find!
Anyone been to Silicon Valley
I've been to San Jose and Mountain View, does that count?
I've been there, too - as a visitor. You have some specific question?
@ shurik (Sorry for the ping) must I walk around with guacamole toast and talk about how elizabeth holmes was terrible but then pitch a startup about redelivering domino's pizza to customers via an app in a different box?
Ha, I was able to make a bad millennial joke, historical reference, and a pop culture reference in a single question checkmate
I live in Silicon Valley. The sky is orange this week... 🌄
@crystal ore maybe from my backyard bonfires that I didn’t start? Lol
how are you making out @velvet pelican ?
spoke with a few colleagues in SF area today, sounds eerie with orange skies and twilight all day
We are surviving staying with my in-laws about 30 miles away from home... home is still there as of noon we shall see if it exists by the end of this tho
any rain in the forecast?
The city i live near was thrown into level 2 evac a couple hours ago
And possible rain Monday-Tuesday but very minimal but the winds have died off so at least there is that
well all the best, sounds like the whole west coast is on fire, my buddy in Phoenix says it's starting to smell like smoke there
Yeah its a mess man. Washington to the north of us about an hour is on fire too...
aren't forest fires somewhat unusual in OR and WA?
Interestingly enough tho there was no smoke at my place this morning so the wind may move it on by
And yeah not super common
There are arsonists that have been starting alot of these fires
... only reason I know is due to listening to the fire department scanner
For my county
that's terrible, nothing better to do than set fires and create havoc...
Anarcists... was interesting listening to a firefighter that was unaware his radio was on tell a cop just shoot em and we will let a fire burn them and say that’s what happened
Was kinda suprised to hear that out of a firefighter
gotta watch those open mics!
Yup not that I disagree on how serious it is. They had 3 groups they cought last night
1 group of idiots should be enough is too many
i guess it's too humid in NJ, never seen more than an acre or two burn here
Yeah there is next to no humidity here right now
are you now out of an evac zone, or did you just move to a lower level one?
@jovial swift im out if the evac zones for now... if the fire reaches where i am now i would go back home cuz that means it would be burned through by my place and out by then
It might mean i would have to tent camp a bit but meh lol
@zealous ermine as long as they are out of danger its fine ppl lose possessions and such and its a bummer but its not as important as gettin out
@zealous ermine when did they evacuate?
a few days ago i think
i'm not sure
they told me over snapchat, but it was from camera role so it could of been a while ago
Well around here if they evaced 2 days ago they were probably south of estacada. They got evaced the day before yesterday and we got evacuated yesterday afternoon.
@stoic mesa Nah
I just saw the history of what Sherman Fairchild did for that place
It was quite a nice tale
I just used a leftover Popeyes spicy breast and my waffle maker to make a makeshift chicken and waffles
And I am proud
For it was delicious

sounds good!
I tried downloading utorrent, and it gave me a virus 😦
i just want to use the arch ISO that MIT offers
Legally utorrent is not legal also its a great way to get all your info stolen and make your computer go 💥
OH NO
WAIT WHAT
i have malwarebytes pro, and i ran it
it installed a PUP, but it got removed. i had to manually uninstall another one that malewarebytes didn
didn't catch
i also unstalled the torrent, i think im safe
i don't really keep anything super important on my machine, so i think im ok???
oh man im freaking out
Well if you have amazon or anything with financial data keep a close eye on it
i think im fine. i don't have an amazon account, and i don't think i put my new card on my ebay either
😬
utorrent isn't itself illegal, what torrents you chose to download would be the legal issue. Also sketchy torrents may have malware etc. Also look into another torrent program, I think utorrent has some adware/default install issues.
well after you clean up change password to all sensive sites
like banking, amazon, etc
i had it on my pachine for abt 30 minutes, and i didn't even try to use it
machine*
A PUP isn't a virus, it's a potentially unwanted program
yeah, its still annoying
As in utorrent by default installs an extra program that you probably didn't want. If that's all that happened probably not much to worry about
yeah that's what happened
been a while since I did anything by torrent, might have been open source qBittorrent that I used last time
my friend told me to use transmission, but thats a linux only torrent, and my desktop is a windows machine
qbittorrent is available for multiple platforms
good to know!
https://thedatabus.io/fpga-buying-guide focuses on higher dollar boards but the intro second are variable for anyone interested in FPGAs
I decided to just look at FPGA boards that are supported by IceStorm to start with. The Nandland Go board is nice, as it has LEDs, switches, some 7 segment displays, and a VGA connector, so I started with that. I later expanded to include the iCEBreaker and the TinyFPGA BX.
Eventually the ICE40 ultra will be on a feather and ready to build SoF system on a feather 🤓
Granted the orange crab is technically a SoF
But it will be cheaper than an orange crab so there’s that 😉
I later picked up in iCEBreaker Bitsy, which is at an appealing intersection of price/size/capability
I'm also looking at rolling my own 😕
I don’t think you get any pins broken out on the orange crab ?
Well, other than the standard feather IO
There's also the Fomu (inexpensive, tiny, and easy to get started, but limited I/O) and the ColorLight boards designed to drive HUB75 RGB LED matrices (not directly supported, but do include 5V level shifters)
Hmm
Very limited I/O on the fomu. It's bound to be perfect for something though, besides showing off how compactly you can lay out a complex board
The design that tannewt had on S&T wednesday is very interesting to me, especially the way you can program it and then control it via a stemma qt connector.
I didn't see that one, is it an I2C controllable FPGA board?
what am i doing with my life
@sick adder @late fulcrum I ordered v1 last night: https://oshpark.com/shared_projects/b9Zj372R
the mach xo's are not currently supported by the open toolchain though someone started the work
I think I need a version with more pins too
yup, only had to shift the fpga once
that's not bad at all
I hope it works 🙂
I wish the ICE5LP 48QFN was that flexible. too much IO to do on 2 layers
and too many power levels to manage as well
ya, that's why the mach xo is nice. it only need 3.3v
it has ~6 power pins though which is kinda weird
how many LUTs?
256 or 1200
not bad
I'm planning on testing my ICE5LP in the 1K LUTs variant and selling it in the 2K and 4K variants
1K is useful but the cost difference isn't too bad to just do 2K and 4K
ya, I need to see what I can do with it
only thing I'm hesitant on is the suggested power up sequence though they said it isn't critical just a good idea if you can
I don't think they imagined it going on a feather
lol
oh.. that would be fun
since the packages with lots of IO are big
either go vertical or split across two breadboards I guess
you get 39 IO with the ICE5LP which is nice since that's over 70% of the pins on the package
the 48 qfn of the mach has 40 but I use 4 for i2c and tclk needs a pull
yeah, 4 are used for SPI
though I was reading that the SPI pins are also hardened for i2c
so the potential is there
@late fulcrum ya! something like that but using a pcie edge connector
I found an obscure table on the lattice website talking about the ice40 ultra have dual hardened I2C and SPI
"Hardened" as in 5V tolerant or something else?
I think "Hardened" as their function is fixed
i'd have to look at the datasheet for the ice5lp
something about shared i2c/spi bus
but i could have read it wrong
oh this is really nice
lookie here
ultra != ultra plus though right?
yup
good thing all these I/O are broken out on my lattice wing
how do you break them out?
to header holes
ice40 ultra has 2 i2c and 2 spi
upper left & upper right for i2c and lower left and lower right for SPI
so technically there wouldn't need to be any porting of your SoC to SPI programming
which means good things, happy times, and one additional revision adding a qwiic/stemma connector to the board.. or two
🙂
I suppose you could add switchable pull-ups as well, but that would eat more I/O pins.
Unless the Lattice pin drivers already include switchable pull-ups (I don't know)
they are multiplexed for GPIO
i wonder if me changing my profile picture and username every few weeks throws people off
who are you ?
I know its a good way to get banned on some discords. In one of the servers i am on they have a rename notice bot so people cant do that
@wheat peak We don't have a rule regarding that -- our rules regarding usernames & avatars can be found in #code-of-conduct [in short, keep it family friendly & appropriate for everyone].
Though as a Discord user myself, it helps to keep one's name consistent, as folks you interact with might not recognize it's been changed.

Heh, "in planet Earth's sky". Alas, when juggling the rules to keep Pluto a non-planet, they inadvertently made Earth a non-planet as well. Oops!
oh no lol
if I recall right the co-center of moon and earth is external to both so earth still clears pathway

Anyone else wish that USB cables were more clearly labeled? Like I have a bunch of cables (in both the micro and USB-c variety) that ONLY do power, no data. And they can’t be told apart until try to plug in your microcontroller only to find it won’t connect.🤦🏻♂️
burn them ....
I use bread tags to label cables
i use a label maker on any cables that don't work great
