Initially my discord username was my animation studio name but I don't think I'm allowed to say it here

So I find other phrases to apply to it for places who don't like my humor

"pew pew" is the sound I've been planning to use for the studio intro on videos but I haven't gotten that far... I would share the teaser for a series I've been working on but uh... Not sure if I'd get booted for sharing it

delicate stream May 23, 2021, 12:32 AM

#

That's a mod question

quartz wren May 23, 2021, 12:32 AM

#

(it doesn't disparage anyone it's just not exactly family friendly and the studio name is dubious)

#

Is it a faux pas to ping the mods and ask?

#

See, I'd ping the mods to ask that but it's a catch 22

delicate stream May 23, 2021, 12:34 AM

I'm just very good at seeing slight color differences

quartz wren May 23, 2021, 12:39 AM

#

I'm good with hue differences but shades are hard

#

Man today just got a lot more tired all of a sudden

#

Re-reading that and realising it is very non-standard in its grammatical structure made me remember a time when I got a group of exchange students to literally rofl by asking if I could borrow their bathroom

#

Apparently they had never come across that phrasing

delicate stream May 23, 2021, 12:53 AM

#

Lol

quartz wren May 23, 2021, 1:49 AM

#

soooo it turns out all you need to do to make a spring solderable is electroplate it

#

which is super easy and cheap

delicate stream May 23, 2021, 1:50 AM

#

lol

#

noice

quartz wren May 23, 2021, 1:51 AM

#

just tested the solder joint to failure and it wasn't even the copper plating that broke, it was the solder between the spring's turns hitting its tension limit

#

very impressed

#

the spring deformed before it even started failing at the solder joint

delicate stream May 23, 2021, 1:52 AM

#

I've never heard of solder springs, so you've certainly got something special :D

quartz wren May 23, 2021, 1:53 AM

#

something I'm exploring in response to someone wondering about where to get solderable springs to make a PCB version of those spring terminal electronics kits and it got me thinking

#

in #classroom...went in there because I was curious and it turns out it payed off

#

because even if nobody else uses this discovery, I will

delicate stream May 23, 2021, 1:55 AM

#

Would be super cool if you ended up making a kit for sale!

quartz wren May 23, 2021, 1:55 AM

#

I want to open up the design though so anyone can make one if they follow the BoM

#

but yeah I guess for the people who just want a pre-assembled kit I could make something

delicate stream May 23, 2021, 1:56 AM

#

I like that model

quartz wren May 23, 2021, 1:57 AM

#

in fact, putting the kit together could be a cool classroom project...teach about electroplating, teach about soldering a circuit board, then when it's done, there's a bunch of ways to reconfigure the circuit to learn about how the electronics operate

#

and since the electroplating can be done safely so long as nobody drinks the copper acetate solution (the ingredients are literally just vinegar, copper metal, and 3% hydrogen peroxide) this is something that could be taught fairly early on

#

and the electrical side of things is safe since I proved it can be done with a phone charger

#

I need to get familiar with kicad

#

eagle free does not have enough board space to operate in

#

well, I might be able to fit a small version of this idea into it

#

but I want to go for a replica of the 300-in-1 kit I had as a kid

#

(more or less)

#

that thing was a beauty until I tore it apart out of curiosity and while it was taken apart decided to take it even further apart for some reason I can't remember

delicate stream May 23, 2021, 2:05 AM

#

I need to play with the 300-in-1 kit I have

quartz wren May 23, 2021, 2:07 AM

#

cries in nostalgia

#

this is the one I want to go for but on a breadboard

#

erm

#

PCB*

#

with a breadboard as a peripheral

#

including the antenna and transformer...those were fun...until I put way too much current straight across the antenna and let out the magic smoke

delicate stream May 23, 2021, 2:09 AM

#

It is not, lemme get a picture

quartz wren May 23, 2021, 2:10 AM

#

but I think I actually want to take this a step further and add a few amplifiers, logic chips, maybe even a 6502 on more advanced versions

#

would want the 6502's spring terminals to be right next to the breadboard though, so that you have the shortest path lengths possible

#

so you don't end up causing crosstalk by having wires strewn across your project

#

and probably use smaller springs for that so you can pack them tighter...or maybe clever geometry I don't really know, kind of just a hazy future plan at the moment...for now I'm going to stick with the simples

late fulcrum May 23, 2021, 2:14 AM

SparkFun used to offer solderable springs https://www.sparkfun.com/products/retired/11822

Spring Connectors (pack of 10)

If these spring connectors look familiar to you, they should. They have been used in a multitude of beginner electronic labs teaching the basics of circuit

Personally, I prefer Lectron

quartz wren May 23, 2021, 2:16 AM

#

that does look like it would be useful for prototyping

#

and learning schematic/circuit relations

late fulcrum May 23, 2021, 2:17 AM

#

That's what I learned electronics with, the ability to whip up a circuit quickly and try things was invaluable. I still play with it.

#

I've build all kinds of stuff with it, like this hybrid AM/FM dual band radio

quartz wren May 23, 2021, 2:17 AM

#

man, I'm a bit envious tbh

#

but at the same time, I had my own ways of learning things that seem to have been effective

late fulcrum May 23, 2021, 2:19 AM

#

There's also Gakken, Brick'R'Knowledge, and Snap Circuits. And Elenco still offers the spring kits (I found a NIB one at a thrift store for $4 a while back)

quartz wren May 23, 2021, 2:21 AM

#

learning valuable lessons by building things regardless

#

I learned a valuable lesson today

#

at the cost of my favorite keeb

#

the only dummy is a test dummy 😉

delicate stream May 23, 2021, 2:43 AM

#

And then spent like 10 minutes trying to wiggle it straight and got it kinda sorta there

#

Lesson: don't do my dumb

#

Also chip clips do not replace helping hands

#

Also also don't solder when sleepy

#

Also also also make sure the parts are ALIGNED PROPERLY BEFORE YOU START TO SOLDER

quartz wren May 23, 2021, 2:46 AM

By "fix" I meant this #adafruit-blog-feed message

Those are very Cub Scout project - usually made of brass and solderable, back then.

yes, but that's like saying that a throwing hatchet and a throwing knife are the same because they accomplish the same goal, it looks the same after you get struck with one, and they're the same style of attack

they're very different in their behavior

though freestyle is only subtly different so I need a better analogy

we were asked to not try to circumvent the filter here.

#

Just gives the mods an additional burden so it's a no-starter.

#

If you are going to type something in detail, it's sometimes helpful to do it in another buffer, as if the filter flags you can lose your work.

#

afaik all flagged messages are saved in a chan only the mods can see.

quartz wren May 23, 2021, 4:15 PM

was not intentionally circumventing the filter, hence editing so that it's more rule-compliant

dusty citrus May 23, 2021, 4:35 PM

#

Just sayin

quartz wren May 23, 2021, 4:45 PM

#

if there's a problem, I'm sure they'll let me know...I honestly have no problem with the filter, and yes that's a great idea for large detailed things that might be gone in the blink of an eye because of an errant word

#

in fact, I was going to say "the only problem I have is a fear of saying a no-no I wasn't aware of and having a bunch of detailed information disappear" but you had already proposed the solution, so I have 0 problems at all with filtering things

#

¯_(ツ)_/¯

#

I don't need to be throwing a wrench into someone's works, get enough of that coming my way to know how it feels...I'm just trying to be accommodating to the rules while also having dispositions that make that hard...if I go over a line, by all means have them ask me to leave and I'll happily go.

So I set up my CLUE to water a plant, and it didn't even last a day before the 3xAAA battery pack died, lol

I think it might have been getting bad readings and over pumped before getting into a boot loop where the CLUE couldn't run the code, because it said 99% when I gave it power again

dusty citrus May 23, 2021, 9:56 PM

#

You can use a gel cell 12V like a wheelchair battery, and down convert to what the CLUE needs (3.3 VDC or 5 VDC or a bit more, whatever the spec is).

#

Then you'd probably have enough energy/charge to do something for 'a while'.

Researchers Built a “Shapeshifting” CPU That’s Impossible to Hack

Researchers at the University of Michigan developed a new computer processor, called Morpheus, that constantly changes its microarchitecture to thwart hacking attempts. In other words, it turns into a new computer even few seconds. Tests funded by DARPA show that the system is, for the time being, unhackable.

delicate stream May 24, 2021, 9:01 PM

#

I might add a couple buttons, but wanna make sure the OLED works first, lol

#

So I plugged it in and it still runs the code I had on it XD so good step

#

So, trying to put the libraries I need for the OLED onto the Trinkey, it's saying I need more space -- it should be 256kb of space, right? It looks like I'm only using about 32kb

honest jolt May 24, 2021, 9:25 PM

CircuitPython does need some space by itself you know 😉

#

Although that is a lot of space 🤔

delicate stream May 24, 2021, 9:25 PM

delicate stream May 24, 2021, 9:30 PM

48KB

#

tardy badger May 24, 2021, 9:32 PM

Yup

#

Unless it has SPI flash attached

delicate stream May 24, 2021, 9:33 PM

#

I thought this chip had 256KB total?

tardy badger May 24, 2021, 9:35 PM

#

Circuitpython uses like 192kB

delicate stream May 24, 2021, 9:36 PM

#

Oh... Ckyiu has lied to me :O

tardy badger May 24, 2021, 9:36 PM

#

Circuitpython uses a lot

delicate stream May 24, 2021, 9:36 PM

#

Ckyiu said 44/47KB, lol

#

Ok, so... how do I deal with not enough space for libs?

#

I can't figure out what/s taking the space... I only see like 4-5KB of files

tardy badger May 24, 2021, 9:38 PM

#

@fair summit might be able to more definitely tell you

#

Or any of the circuitpython people

#

But as far as I know it’s really big and you don’t get a lot of additional space on the M0 unless they have SPI flash

delicate stream May 24, 2021, 9:39 PM

#

So I might be dooooomed

#

rats

#

I blame you for not warning me :P

#

Are there totally hidden files? because the only files that show taking space are boot_out.txt at 1KB, files under adafruit_bus_device taking less than 2KB, neopixel.mpy taking 1KB, and code.py taking 1KB, but that only adds up to like 5KB out of 41KB used

#

Actually there's a couple things in System Volume Information , but those only take like 88B

tardy badger May 24, 2021, 9:44 PM

#

The display driver probably won’t fit on the slider trinkey

#

As far as I know you need SPI flash

delicate stream May 24, 2021, 9:48 PM

#

Fwaaa...

#

My careful soldering, all for naught

#

But I wanna know what the heck is using the other 36KB

fair summit May 24, 2021, 10:21 PM

#

the raw size of CIRCUITPY on the non-external-flash SAMD21 boards is 64kB. With overhead it's smaller. If you are on a Mac, pay particular attention to this: https://learn.adafruit.com/welcome-to-circuitpython/troubleshooting#macos-loves-to-add-extra-files-2978466-47

and yes macos does love to write tons of temp files which eat up your space

delicate stream May 24, 2021, 10:28 PM

Uhh... not sure if this is permissions?

fair summit May 24, 2021, 10:38 PM

we create a special .Trashes file so that it won't create a .Trashes folder.

delicate stream May 24, 2021, 10:39 PM

#

Oop... it did do that

fair summit May 24, 2021, 10:40 PM

#

it prevents macos from creating yet more files of some kind or other

#

it's explained in that link

delicate stream May 24, 2021, 10:40 PM

#

I manually deleted .Trashes and I was able to touch

#

Ah, I noticed something... it shows storage.erase_filesystem to clear storage, but storage.erase_filesystem() is what does it

#

Mmmk, now I have 47KB free, so I think that'll do the trick, along with the "copy without hidden folders" tip :D

#

Maybe I should just do this on Windows XD

dusty citrus May 24, 2021, 11:04 PM

#

@static flare There's a small buffer in the LCD you can read from.

#

That's why read/write.

#

HD44780 that is.

#

That's the original Toshiba chip p/n iirc.

#

Nobody runs those in 8-bit mode and I don't remember 'taking care of' the unused 4 bit lines.

#

They wouldn't be tied to ground in a typical module because someone will say 'hey I thought this could do 8 bit mode but you've tied half of them to ground'.

#

So they're usually just left floating, I'd guess.

fair summit May 24, 2021, 11:38 PM

delicate stream May 25, 2021, 5:11 PM

#

Yeah, while it's technically illegal, having an underage person consume small amounts under their parent's supervision is better than them going out and ~~doing all the dumb things when I was a youngling~~

quartz wren May 25, 2021, 6:13 PM

#

Actually, a parent or grandparent may give their child / grandchild alcohol in their home.

#

(legally)

delicate stream May 25, 2021, 6:15 PM

#

I just looked it up... Apparently some states do allow that. But it's by state

dusty citrus May 25, 2021, 6:15 PM

The <n> can <m> and nobody stops <them> either.

#

(and <m> would not enjoy much support by the general public, let me tell you)

quartz wren May 25, 2021, 6:16 PM

#

Ah I guess I must've just looked it up for my state before

delicate stream May 25, 2021, 6:16 PM

#

Yeah, here, it's not legal for anyone under 21 to have any alcohol

#

But still, in instances where it is illegal... I think a parent letting their kid have a beer and allowing them to explore consumption in a safe, guided way, is much better than having them sneak out and drink and party

#

At least when they're a bit older, little kids should not consume the adult happy juice

quartz wren May 25, 2021, 6:19 PM

#

Yeah, of course it must be done with discernment

#

Just like any potentially dangerous activity

#

But if you don't want someone to harm themselves doing a potentially dangerous activity later in life, train them how to do it safely when feasible

I once was working in a boom lift that had issues and one time the arm wouldn't swing down... Was working alone so I had nobody to work the ground controls... So I shimmied down the arm and did the ground controls myself XD

#

I probably could've done that job without the boom lift (actually did a good chunk of it without even using a ladder because there were so many things to climb in a partially renovated factory)

#

I'm less stable on a ladder than I am just climbing my environment

#

Okay so one of my tasks truly required the boom... Had to move some giant steel tension members from one wall section to another to make way for some doors we were fabricating

#

That required the boom and rope / bits of scrap PEX fashioned into a makeshift pulley system to remove

#

Because while it was a minimum 2 man job, I was asked to do it alone.

Anyway there were a lot of things at that job which were 2+ person tasks I was asked to do alone because they knew I could... And still didn't pay me anywhere near what I was worth (even after a string of promises about raises and working to prove I was worth it)

I know I saw a video about it at one point but it's so convoluted I intentionally omitted it from memory

#

No reason to hold on to garbage procedures, just learn intuition for the system from the outside

#

;)

dusty citrus May 25, 2021, 6:54 PM

#

They use Oh I cant remember the unit .. in Basque Spain.

#

pilgata or something like that.

#

and they're pretty close to either inches or to CM I think.

#

Maybe just in that one industry where it'd make less sense to retool.

quartz wren May 25, 2021, 6:55 PM

#

We all just need to accept our lord and savior, the metric system

#

As encoded in fundamental constants of nature

dusty citrus May 25, 2021, 6:56 PM

#

Base 12 is useful and underutilized.

quartz wren May 25, 2021, 6:56 PM

#

I like base 2 and base 16

#

But yes base 12 is fun and useful

dusty citrus May 25, 2021, 6:57 PM

#

Too many individual identities in 16 and too few in 8 and arithmetically challenged in 10. 12 is the sweet spot.

delicate stream May 25, 2021, 6:58 PM

#

I would be fine with metric for all the things. But I still want F for weather because it's easier to think about how temperatures effect humans and human-like creatures since the 0-100 is roughly the range of "habitable"

quartz wren May 25, 2021, 6:58 PM

#

Nah, 16 individual identities is nothing. I have a project idea in mind to give a different name to every day of the year.

quartz wren May 25, 2021, 7:00 PM

#

Obviously all the holidays are just their holiday name which makes them have multiple names in some cases of overlap, leap day is just leap day... The rest I'll get to eventually

The slogan of the project is "make every day a holiday"

#

No I have not released anything I've put together for it... Because there really isn't anything to release until I figure out how best to go about naming days. I'm thinking crowdsource name ideas, then have open voting but that could get a little... Problematic

🔸 🔸
I have a calendar that is basically just columns of numbers - have about 9 sticks I use.

#

Each side of the sticks (2-sided) shows the same column, but shifted one row.

#

1 8 15 22 29

#

vertical

#

The 1st of the month is always on the top row.

#

But no other day has to be.

#

I did them in wood - old futon slats cut about -- 12" long or a bit longer.

quartz wren May 25, 2021, 7:07 PM

#

That's actually really cool

dusty citrus May 25, 2021, 7:07 PM

#

So every month I just rearrange them to suit.

quartz wren May 25, 2021, 7:08 PM

#

I may borrow this design to make a 3D printable version if that's alright

dusty citrus May 25, 2021, 7:08 PM

#

and If I want to be extra precise, I drop 30 and/or 31 on short months by making extra copies of the 3 column and the other one.

#

3 10 17 24 31

#

that's the 3 column so the other one's the 2 column.

#

So thats why about 9 slats not 7

#

to go with/without 30 and 31 ;)

#

Oh I gave up long ago trying to turn this into a money maker. ;)

#

go for it.

quartz wren May 25, 2021, 7:09 PM

#

In fact, I could whip that up in blender in no time...

dusty citrus May 25, 2021, 7:10 PM

#

I was going to do it in that substrate they use for desk signs saying the person's name. Those are two-tone layered plastic foo and are routed, more or less.

That's another one.

#

You move the slide rule window over a group of seven adjacent columns.

quartz wren May 25, 2021, 7:13 PM

#

Hmmm that could easily be made into a print in place captive slide

#

Would need to be done parametrically so the clearance is the same regardless of scale

dusty citrus May 25, 2021, 7:15 PM

#

The way I saw it done was to permanent-element LCD it all and light up only the segments required for that month's calendar.

#

Instead of sliding, they just failed to illuminate unwanted side-data.

#

but you could do it with a cardboard slide.

#

I use the pattern in a textfile to generate an annual calendar.

#

jan-hi feb-lo mar-hi apr-lo may-hi jun-lo jul,aug-hi sep-lo oct-hi nov-lo dec-hi

#

and then JH Conway it to get the day of the week. 4/4/2021 was a Sunday - I know the entire 2021 calendar from this one fact. ;)

quartz wren May 25, 2021, 7:18 PM

#

well that's a nifty trick I'll need to commit to memory at some point

dusty citrus May 25, 2021, 7:18 PM

#

Conway observed that 4/4 6/6 8/8 10/10 and 12/12 all fall on the same day of the week.

#

Likewise 5/9 and 9/5 do; and 7/11 and 11/7 do.

#

That's 9 months right there.

#

Add in 'March zeroth' and you have Feb and March covered.

delicate stream May 25, 2021, 7:19 PM

#

Conway as in Conway's Game of Life? that's one of my favorite things :D

quartz wren May 25, 2021, 7:19 PM

#

heh march zeroth

dusty citrus May 25, 2021, 7:19 PM

#

That leaves January: 3 in 3 years; 4 in 4th year.

quartz wren May 25, 2021, 7:19 PM

#

dunno why but that made me chuckle

dusty citrus May 25, 2021, 7:19 PM

#

March 0th is Feb 28 or Feb 29, depending on leap year.

#

;)

quartz wren May 25, 2021, 7:20 PM

#

I figured, I just thought it was funny

dusty citrus May 25, 2021, 7:20 PM

#

All those days fall on the same day of the week (2021 is Sunday).

delicate stream May 25, 2021, 7:20 PM

#

March -365th

dusty citrus May 25, 2021, 7:21 PM

#

1/3, 2/28, 3/0, 3/7, 4/4, 5/9, 6/6, 7/11,8/8, 9/5, 10/10, 11/7 and 12/12 are all Sunday in 2021.

quartz wren May 25, 2021, 7:21 PM

#

why don't we just have the year end partway through a day? what's so wrong with a partial day? then we remove the need entirely for leap day and can be much more precise

dusty citrus May 25, 2021, 7:21 PM

#

7/11 is also July 4th ;)

#

(if 7/11 is a Sunday, then so is July 4th)

quartz wren May 25, 2021, 7:22 PM

#

we have computers to handle processing the timing of the event, the calculated shift based on best orbital measurements of earth, etc.

dusty citrus May 25, 2021, 7:23 PM

#

So with all those data points it's not hard to come up with the day of the week for any day at all in a given year.

#

Conway died this year. Probably covid.

quartz wren May 25, 2021, 7:23 PM

#

#

sad news indeed

dusty citrus May 25, 2021, 7:23 PM

#

I should have sent him a card while he was alive. ;)

quartz wren May 25, 2021, 7:24 PM

#

he was on my list of people to eventually meet and now it's never going to happen.

delicate stream May 25, 2021, 7:24 PM

https://en.wikipedia.org/wiki/Doomsday_rule

#

The old blind guy in my building who was into calendar math told me about bissextile for February.

quartz wren May 25, 2021, 7:25 PM

#

we're all going to die eventually...it just appears it wasn't fated for my cycle of energy propagation to mingle with his

dusty citrus May 25, 2021, 7:25 PM

#

The Romans counted their calendar backwards.

#

It was a countdown to a holiday. ;)

quartz wren May 25, 2021, 7:26 PM

#

makes sense, "how long 'til the big party broooooo?" gives date

dusty citrus May 25, 2021, 7:26 PM

#

Right. So Ides Nones and Kalends

delicate stream May 25, 2021, 7:27 PM

#

We should switch to a 13 month calendar

dusty citrus May 25, 2021, 7:27 PM

#

bissextile basically means two sixes.

#

I guess that means the 6th day before the Kalends.

#

I don't remember his (almost a) rant.

#

So apparently that Feb 28/29 business is known (also) as 'bissextile'

#

https://en.wiktionary.org/wiki/bissextile

quartz wren May 25, 2021, 7:29 PM

#

okay so a 13 month calendar would consist of what, 4 weeks a month with the 13th month having either 29 or 30 days depending on leap year?

dusty citrus May 25, 2021, 7:30 PM

#

For the hi-low pattern of month length, I just count knuckle, space, knuckle, space.. on my hand.

#

jul-aug are both long.

#

and interrupt the pattern.

#

A true month would relate to the moon, but not necessarily to civil observation of it.

#

They're gonna be making a Mars calendar pretty soon.

#

If it's not already settled.

#

The proposal I heard was January 1st, A followed by January 1st, B-day, and that repeats for our entire year.

#

The Martian year is double our year I think.

#

365 * 2

#

plus or minus some fudge factor

quartz wren May 25, 2021, 7:33 PM

#

1.88 earth years says google

dusty citrus May 25, 2021, 7:33 PM

#

Either that or it's very close to ours but the rotation is slow. I think their rotation is remarkably similar to Earth's.

quartz wren May 25, 2021, 7:33 PM

#

yeah, the day length is within an hour of earth's iirc

dusty citrus May 25, 2021, 7:34 PM

#

I use UTC for everything.

quartz wren May 25, 2021, 7:34 PM

#

some 45 minutes longer but let me verify

#

37

#

close enough

#

that's like my "let me wake up" period...if I lived on Mars, I'd be able to have a full day that matches my internal cycle

#

on earth I drift

#

like, I'm pretty sure that my unchecked rhythm is almost exactly that of mars' day length

#

whoops, clearly not enough coffee yet

dusty citrus May 25, 2021, 7:36 PM

#

National Geographic sent someone into a mine shaft for like 50 days to establish what a natural rhythm for wake/sleep was.

#

Many years ago.

quartz wren May 25, 2021, 7:37 PM

#

I'm talking even when I have the earth's solar cycles triggering my patterns, I drift on my wake / sleep schedule steadily

delicate stream May 25, 2021, 7:38 PM

#

1 day calendar

dusty citrus May 25, 2021, 7:38 PM

#

If I look at the clock and it is past my bedtime I just insist it's not my bedtime. ;)

#

Which causes problems the next morning.

quartz wren May 25, 2021, 7:38 PM

#

I end up shifting forward through the day until I'm up all night and sleeping during the day, then I either force myself to reset or I let myself drift forward some more until it's reset naturally

#

I haven't precisely quantified the cycle, but I probably should...

dusty citrus May 25, 2021, 7:39 PM

#

I tried 36 on 12 off for a while. ;)

quartz wren May 25, 2021, 7:39 PM

#

oof

dusty citrus May 25, 2021, 7:39 PM

#

The 36 was kind of tough. ;)

quartz wren May 25, 2021, 7:39 PM

#

I used to do sleep deprivation experiments in high school because, let's face it, I've always been researching something and I'm a willing test subject so I understand

delicate stream May 25, 2021, 7:39 PM

#

In college I'd often be awake 6-7 days and then crash for 12 hours for a night or two on the weekends

dusty citrus May 25, 2021, 7:39 PM

#

Yeah I think a 27 hour day would more predictably tire me out enough to sleep on a schedule.

#

6-7 days with no sleep at all?

quartz wren May 25, 2021, 7:40 PM

#

I once stayed up for 52 just to see what would happen

#

(hours)

dusty citrus May 25, 2021, 7:40 PM

#

I don't think I've ever lasted 52 hours. ;)

quartz wren May 25, 2021, 7:41 PM

#

I was trying to make it to 72 but I didn't...

delicate stream May 25, 2021, 7:41 PM

#

One time I was awake for over 260 hours and basically lost my mind

dusty citrus May 25, 2021, 7:41 PM

#

I developed the very bad habit of sleeping sitting upright in a chair.

quartz wren May 25, 2021, 7:41 PM

#

after about 40 things get....a little trippy

delicate stream May 25, 2021, 7:41 PM

#

Do not stay up for 260+ hours

quartz wren May 25, 2021, 7:42 PM

#

36 is about the giggle yourself into complete soreness point

#

at the most random stuff too

dusty citrus May 25, 2021, 7:42 PM

#

The 36/12 thing was in 1982 or so. ;)

quartz wren May 25, 2021, 7:43 PM

#

oh and for at least someone with bipolar...36-40 is a bit dangerous...

#

but after that things mellowed

dusty citrus May 25, 2021, 7:44 PM

#

If you sleep, your mind can store what you've learned that day.

quartz wren May 25, 2021, 7:44 PM

#

I regularly did 48 at the time when I was trying for 72

delicate stream May 25, 2021, 7:44 PM

#

How I feel at certain hour marks depends on how much I've been sleeping generally -- but in college I'd often get a second wind at 24 hours, which would wear off at around 36 hours, 48 hours I'd have major fog brain, 72 hours I'd be pretty useless, 96 hours I'd be incredibly loopy [thankfully that was exceedingly rare], and the one time I was over 100 hours awake was the time I was up for almost 12 days and lost my friggin' mind

dusty citrus May 25, 2021, 7:45 PM

#

Yeah avoiding the second wind is critical to my maintaining a diurnal sleep schedule.

#

So when I feel that yawn that says BED. NOW. I try to obey it quickly.

quartz wren May 25, 2021, 7:46 PM

#

after hitting the 52 hour mark, I slept for at least 2 full days...I was living alone at the time so my friends came to check on me because I was out of contact for like a week so my friends came to check on me, and I woke up let them know I was fine, then continued to sleep for another day

dusty citrus May 25, 2021, 7:46 PM

#

Which means prep, a few hours earlier, so that everything's in good shape for instant off at bedtime.

delicate stream May 25, 2021, 7:46 PM

#

It's been a long time since I stayed up more than ~30 hours

#

40 hours?

#

Like, skip one night and bed normal time the next day

dusty citrus May 25, 2021, 7:47 PM

#

Yeah that happens a few times each year, but, I fell asleep for 2 minutes multiple times on those days.

#

So the system responsible is taking care of business and removing me from conscious awareness from time to time through the day (only when seated and quiet, of course).

#

I cannot recommend any of it to anyone. ;)

delicate stream May 25, 2021, 7:49 PM

#

I've done a lot better sleeping since I got a CPAP

quartz wren May 25, 2021, 7:49 PM

#

yeah, sleep and I have a...complicated relationship...and I often wake up questioning my sanity after a particularly visceral dream

#

had a dream the other night that an airplane lost its wings mid flight and landed right in the yard I was in

dusty citrus May 25, 2021, 7:50 PM

#

Questioning reality is an artifact of the end of sleep.

quartz wren May 25, 2021, 7:50 PM

#

no I mean like

#

for days

dusty citrus May 25, 2021, 7:51 PM

#

Like one time I had blue eyes in a dream and was genuinely surprised that they were found not to be blue, in the mirror, moments after rising from a sleep that ended with that dream.

quartz wren May 25, 2021, 7:51 PM

#

I'm still having trouble with the airplane dream because even looking back on the dream it isn't like "oh this thing would definitely have tipped me off that it was a dream in the moment if I'd noticed it"

#

it still feels like I actually lived the events

delicate stream May 25, 2021, 7:52 PM

#

Once I had a dream where I went to bed irl, "woke up" in the dream, had basically a month experience in the dream, went to sleep in the dream, and woke back up irl... I thought it was a month later and didn't realize it until later that day someone asked me why I put the wrong date [which was actually 1 month later!]

#

Brains is weird, yo

dusty citrus May 25, 2021, 7:52 PM

#

quartz wren May 25, 2021, 7:53 PM

#

the only dreams I've had in the past where I look back on them and I feel like I've actually lived the events turned out to be premonitions of horrible things. for instance...the boston marathon incident...had a dream about that literally the night before, and was super confused in the dream and when I woke up...but as soon as I saw the news my stomach just dropped out

delicate stream May 25, 2021, 7:53 PM

#

Yes, as I said, I had been shoved thru that window

#

Brains are crazy machines that do all sorts of crazy things

quartz wren May 25, 2021, 7:54 PM

#

I literally saw the event as though I was there before it happened. crazy is one way to describe that and probably me 😉

delicate stream May 25, 2021, 7:55 PM

#

lol, I get premonitions too

#

But mine are all... mundane

#

Like remembering a conversation before it happens

quartz wren May 25, 2021, 7:56 PM

#

I just hope the one I had the other night isn't something I have to worry about...rather not see that in person or on the news

delicate stream May 25, 2021, 7:56 PM

#

oof...

quartz wren May 25, 2021, 7:57 PM

I'm pretty sure it was carrying ordnance too because it went big boom

#

or is it the other way around????

"conventionally" in this case meaning larger numbers are considered higher

My brain has trouble with problems of that general class, where there are basically two possibilities. For whatever reason, I do fine when there are more than two. For two, I use the wretched trick of trying to remember whether it's the one that "feels right" or not. However, for the ones where the "feels right" one is wrong, I'll eventually get used to the "correct" one, and get confused all over again.

#

Did you see the link I posted about IBM's Chinese typewriter?

quartz wren May 27, 2021, 1:05 PM

#

See the key to both large character sets and large number bases is the same, symbolic structure with patterns. In the case of number systems, repeating patterns. In modern number bases we have taken it a step further and abstracted that symbolic system to be able to self-describe recursively

#

This is all very hard to type on a phone lemme switch to pc real quick

#

I'm a bit to pre-caffeinated and under-rested to do the proper googlage for the full description but from what I understand, the base 60 number system that I heard about used symbols that had a particular structure, and as you got to larger and larger numbers, you would structure that structure in a particular pattern, so while there were technically 60 unique symbols, they were made up of common sub-structures that I suppose you could say were another number base themselves

or I could be imagining this whole thing I've been up all night

I think skywater and Googles shuttle is really quite cool, and efabless is doing private shuttles for $10,000 for 300 bga parts. I think we are seeing what happened with PCBs soon, not to the same degree but this group on the same wafer concept may really catch on

#

Not to mention OpenPDK, OpenLane, ngspice, and the other tools being used... that stuff makes silicon design way easier than someone would think

brittle glacier Hey does anyone here code in verilog or vhdl? I've got a fun and crazy project ...

OMG this looks like it would be fun...just have to get back into HDLs

#

even though they really aren't something I enjoy, much prefer mapping it out visually...I can map visually and convert to code though 😉

polar bloom May 27, 2021, 9:54 PM

#

Problem is that HDLs are waaaay different than normal source code. The easiest way is probably to implement a custom CPU that interprets the Doom source code.

quartz wren May 27, 2021, 9:56 PM

#

possibly but depending on the source code it should be possible to abstract the function of the code into something you can rework into a logic implementation. it would probably be more efficient to have a CPU core that interprets the code, but it should still be doable to convert the code

polar bloom May 27, 2021, 10:00 PM

#

Sure, but what's the point? You'll end up with something that will work like a CPU anyway.

#

#

it's not a "this is something that we need to figure out" kind of task but a "I wonder if I could figure this out" kind

polar bloom May 27, 2021, 10:01 PM

#

Hey, I wouldn't try to stop anyone from either.

#

But sometimes people aren't quite realistic about the amount of effort involved in certain tasks 😉

quartz wren May 27, 2021, 10:02 PM

#

yeah, but for me even if I don't complete the task I do enough of it to learn what I was trying to learn

#

or prove some concept

#

for instance, I've not designed a complete functional CPU in Minecraft yet, but I have designed each of the pieces required separately...there wasn't really much more to learn by connecting them together so I decided to do that in logisim instead

#

but I have learned some valuable things about tick syncing since it's more exaggerated in the Minecraft environment

#

so while I didn't finish the initial goal I set out for, I proved to myself I could do it and moved on to the next stage of learning

polar bloom May 27, 2021, 10:05 PM

#

Sure, that's cool 😄

#

I do the same thing.

quartz wren May 27, 2021, 10:07 PM

#

the next phase of my CPU design journey is virtual machines on microcontrollers 😄

#

custom architecture, so pure virtual

#

well, I'll also be doing a GBA emulator for my handheld too

#

but the main architecture that I'm going to emulate on-board will be a pure virtual arch that I'm designing from scratch

#

with the express goal of allowing any microcontroller to run the games

#

or rather, any combination of microcontrollers performing the various tasks of the system (game code, 3D calculations, rasterisation)

#

and the render pipeline will stay in screen space until actually rendering to a screen, at which point the rasteriser firmware will convert the screen space coordinates to the pixel space coordinates

#

which means I can take that same data from the 3D->2D projection and put that out to 2 other units each with their own resolution and it will render properly

#

(so if I have a header that spits out the triangle data, I can make it have an external screen that renders out a higher resolution version of what's on the handheld)

#

in fact, I'm thinking I may make this unit dockable to the VGA signal driver that I'm working on, in a similar fashion to how the nintendo switch operates

#

but with a design that's replicable in a home shop

pearl vigil May 27, 2021, 10:18 PM

#

You can fit four RISC-V cores on that space, I would rather two cores and a DDR controller + SPI interface, then you could just load doom from SPI flash

I just started drawing up designs for a CPU architecture I want to implement on my FPGA kit that should fit alongside a VGA driver and HDMI buffer. it's a 16-bit fixed-width instruction set with some tricks to allow you a lot of flexibility with very little added complexity

#

😄

#

turns out if you add XOR gates to the inputs of a bitwise OR and bitwise XOR tied to a common control signal from the instruction's bits, you can selectively invert those inputs, giving you NAND and, well, XOR again but then if you also add the same system to the outputs but controlled by another bit, you also allow NOR, XNOR, and AND as well

means I can get a full range of 16-bit bitwise operators for only 64 XOR gates and 16 OR gates

#

the only multiplexing I need to do is a simple 1 to 2 demux for selecting input buffers to either of the 2 sub-modules (OR / XOR)

#

and output from them

#

no reason to have dedicated hardware for each bitwise operator if you can convert one to most of the others with a simple invert on the inputs and outputs each controlled by a separate bit in the opcode. if I ignore XOR (which can be done serially using the other module anyway) then you get all the same operators for 3/4 of the gates

#

and if you forego the XOR, which I may actually do, then you also don't need any demux/mux logic internally to the bitwise operator module

#

and for just the 16-bit module capable of OR/AND/NOR/NAND in a single operation and XOR in...I think 3 operations, that's only 32 XOR gates and 16 OR gates

#

with select logic coming from the multiplexing at the level above that in the instruction decoder

#

erm, okay slight miscalculation, it's 2x16 XOR gates for inputs, 16 XOR gates for the output so a total of 48 XOR, 16 OR (though you could actually put any of the permutations the module is capable of outputting as its true internal gate and it would still work, just with a different pattern of option bits)

hmmmmmm

#

I am sleepy and this is going right over my head

quartz wren May 28, 2021, 1:29 AM

#

the gist is 64 gates is less than 64 gates plus extra logic to select which to use

This makes sense to sleepy brain

I've been wanting to get in to FPGA programming

#

seems neat

they're here way before i expected them to be, so I don't have the parts from Adafruit I need to populate the boards (literally was going to order them next week)

brittle glacier Hey does anyone here code in verilog or vhdl? I've got a fun and crazy project ...

okay, our best hope of a 6502 tile engine has arrived :-)

I'm a little bemused by chaining gates to get selectable functionality in an FPGA, as the FPGA already has LUTs to select gate functionality directly.

#

late fulcrum I'm a little bemused by chaining gates to get selectable functionality in an FPG...

I think its because they want it to be on skywater silicon after the FPGA

quartz wren May 28, 2021, 5:30 AM

#

Well, I'm chaining gates for this design in the logic block diagrams that I would use for designing a die or building it from discrete logic

#

But I'll use whatever facilities give code compatibility with the ISA most efficiently in whatever medium I'm working

#

The idea though is to be efficient at the gate level... I want to implement this ISA in ProjectRed in Minecraft

#

I have all but two of the opcodes figured out for this ISA and I already know how I want to set up registers, addressing, and a few other things that had been hanging me up when trying to design this the first few times... But it kind of just clicked today

Nice! I take it you found a place to live.

static flare May 28, 2021, 12:14 PM

#

I've been living here since I joined this community! im... lucky homelessness hasn't been an issue in a few months, and hopefully one day it won't be an issue for me ever again

#

still uncertain about staying here past July tho, it could go one of 2 ways

#

got a really cool OT who might actually ask the government to build me a house (specifically for me and my mobility needs and such), which i didn't know was a thing until she mentioned it, but if that doesn't end up happening, we're gonna move to somewhere that's better, cause this place has stairs and my legs don't work right

delicate stream May 28, 2021, 12:25 PM

#

I hate stairs

#

I wish we could just have everything either be 1 floor, or have ramps or elevators

#

Soooo.... Slider 11 doesn't seem to work on my FunHouse DX

#

Doesn't the FunHouse come with CP out of the box?

#

Not showing as a drive...

delicate stream May 28, 2021, 1:38 PM

#

It seems like 2 pads trigger slider 10

#

I can't see anything like a bridged solder joint

delicate stream Doesn't the FunHouse come with CP out of the box?

It doesn't. It comes loaded with the Arduino test code.

Ohhh....

Ugh, yeah, high up on my list of annoyances is the lack of mobility infrastructure by default. The first floor of my place mostly has the measurements to be wheelchair accessible by the ADA specification, but I still had to help lift a wheelchair over two steps when I had someone over who uses a wheelchair.

delicate stream May 28, 2021, 2:45 PM

#

I'm pretty certain my house is 0% ADA compliant...

#

4 stairs to get in the house

#

I don't think it could even be made ADA compliant without removing the front steps and replacing them with a lift

burnt tendon May 28, 2021, 2:59 PM

#

Yah my perpetual refrain is that it doesn't have to be this way.

static flare May 28, 2021, 3:01 PM

#

Luckily I can walk a little bit so it's fine that we have steps at the front door, but I'm also glad i have my wheelchair for actually going out and such

delicate stream May 28, 2021, 3:06 PM

#

I'm thankful that my legs mostly work most of the time

burnt tendon May 28, 2021, 3:07 PM

#

Person who I had to lift over the steps had fully bedazzled their wheelchair.

delicate stream May 28, 2021, 3:07 PM

If I needed a wheelchair, I'd probably have it covered in all sorts of tech
