ahh
They list 3 dimensions
well it should have 370 hole mounting.
i dont see it written
you can easily make an adapter plate
This is a great idea
so this one is 4800kv. so 1.2v for 6000rpm.
whihc will reduce power but it sound slike you dont need power anyway
just need a 2S (2 cell, 7.2v nominal) controller board
I don't need power it just needs some torque to move a cam that actuated a head block got a tape deck @rapid geode
It works for like
1 second at a tme
Yeah but I am closer to my goal here nontheless
you tend to get poor low speed smoothing on these drivers/motors
because they are sensorless
I can an add an encoder
Imagining a tape head thumping away at 6000 thumps per minute
but 6k shouldnt matter
Jts not the tape head hold on
i assume its some gear driven assembly
@rapid geode
I have tried to use 310 movies
*motors
But they can be too weak or too fastv
But the 310s do have a pattern that almost works
I just need to do some filing
proof the sun is made of magnetsa
so cool to see
(my friend took this pic in eastern canada)
Great day to listen to SoundGarden
interesting
dynobot hit me for a bad word or maybe it was just posting a youtube link? i have no idea.
bad word as part of the video id. want me to tweak it so you can post again?
nah that's ok
It's all playing in our heads now, video or no.
Not as great as others but
that is gorgeous
looks like "the ring"
oooh pretty. that looks similar to here with a slight cloud cover
isnt it convenient the moon is the exact right size to block the sun and see the corona?
hehe
i like that your solar flare is clocked 30 degrees back from my friends. probably could work out the location from that (no idea how)
Wads of trigonometry, and faith in well leveled cameras and accurate timings?
haha glad you noticed that, that's caused by the camera mounting orientation actually
ah
The size and distance...
@rapid geode
I have been talking to some companies so I'm going to be buying 500 370s
And importing them
They will move the bolt pattern
And change the bolt size
Hi I have a question, is it better to use the LTR390 sensor to measure uv+ambient light (exposure) or to use other sensors to measure uv + the other one to measure the ambient light
As far as I know, the LTR sensor allows you to measure these two "values "
since the corona has some large (but varying) diameter, I wonder what the range of distances would be where the sun could be fully eclipsed and still allow some view of corona
i know that the moon at its closest shows a solid ring of light in an eclipse, and yesterday was near the furthest
i think this was basically the "perfect" eclpse which is why people were more excited about it that other recent ones
Rip Peter Higgs
He helped pioneer modern physics and particle accelerator research into the unknowns of quantum.
The moon is on an ellipitical orbit. It has an apogee and perigee (the distance to Earth fluctuates). It would have to be just the right distance for that to happen. The same thing that happened yesterday, it was a perfect distance and was a real full solar eclipse. The real question for yesterday should be where was it in relative terms to its apogee/perigee. If the moon can get closer to Earth than yesterday then an even darker and longer eclipse is possible.
I have seen a total solar eclipse and an annular eclipse. Pretty neat.
Personally, I think lunar eclipses are cooler. The ominous red glow of the atmosphere on the moons surface. Superb
Don't be, that was funny.
It's ok, I'm English.. not Canadian. 😅
Don’t worry aboot it
It's all good, ehh.
i was wrong, its the reverse. closer moon blocks more sun
this one blocks most of the sun no?
ah yes. anular is when the moon is farhter
i keep mixing it up
hehe
cause i was wondering why this eclipse people seemed more interested in than others
cause it blocked more sun
yeah the moon actually reaches perigee (closest to Earth) tomorrow. That's why the eclipse was so full. Who knows if we'll ever see an eclipse this close to perigee again in our lifetimes.
2045 goes right through where I live now
2044 a polar eclipse
I'm going to make a guess and say yes, this is was a once in a lifetime experience then. We'll never see it that close to perigee in our lifetimes again.
aus is 2028 and 2030
last one here was 1925
i remember seeing one in the 90s, but it must have been annular
or partial
need to look it up
Ahh the 90's, so full of Halley's Comet, haven't heard about Halley in a while. Might see it again in 2061.
I don't remember that one. When you say was I supposed it did not? That doesn't give me confidence in our ability to correctly predict the trajectories of comets then. We need an orbital defense system. 😛
hehe
it didnt hit, but it basically vapourised as it came around
but they thought it might get pull in for an impact
its funny cause there was footage of the comet with earth which is an unusual angle
I think most things would vaporize before hitting the sun. It would have to be massive to survive long enough to touch the surface.
i dont remember where the probe was
NASA’s STEREO spacecraft
aha
ah. thats what i thought. its basically orbiting the sun roughly near earth
Last time I saw an eclipse was like 2014. I looked directly at it for a couple of second involuntarily. It was painful.
This sounds silly, but how would you make a self advancing date stamp (Like those self inking rubber stamps that put the date on things.
And how small could it be made?
(or, which channel should I put it in.)
parker space probe -- it's actually gonna "touch" the sun this year (it's also going faster than a 🦇 out of heck
didnt they crash something into the sun a few years ago?
hiya! I have acute open-plan office. Any noise-cancelling wireless (over-ear) headphone suggestions, preferably something that won't break the bank? Thanks!
they're crashing stuff into moons and planets all the time, some on purpose some not.
I really wonder how long of an extended mission Parker is going to survive for.
This idea could well go in #help-with-projects
well, this blocks out everything but what you're listening to Audio-Technica ATH-M40x, but it's not actually noise-cancelling
i do have a Jabra over-ear, but it ain't cheap
Thanks! realized a short while later that a fancy label maker that allows custom fonts would also do the trick!
Here is/was my monitoring station
are there any adafruit modules that need soldering and they came unsoldered? i need something to rpactice
Most require soldering of header pins to use them with breadboards and other accessories
do u know any sensors/modules which are fun to use in a project and unsolderd?
cause i might be buying the hakko fx888d
I don’t think they sell many kits these days. They do occasionally sell solderable PCB art kits
i havent soldered in like 4 years
kk ill check some out
Just throwing in my 0.02 worth here, but if I were going to practice soldering, rather than using a potentially useful microcontroller / breakout, I'd start with a bunch of 0.1" header which you can get online for next to nothing, along with some through hole plated 0.1" breadboard, and just solder lengths of header to the breadboard.
ok
Not useful in the least, but it's a dirt cheap way of practicing to get the skill back.
That said, based on my own experience, if you have a steady hand and you've soldered before, it's like "riding a bike" - you should find it comes right back to you.
Howdy. As far as soldering, I'm good enough, but still hate it. Anyway, started many years ago with these cheapo Futurelec protoyping boards for Arduinos, and here's my latest I did for a Feather and EyeSpi connector, and 5V power. I know you can buy Ada doubles/triplers, of course I have several. But this board gives me a barrel plugin for Feather, and it's a "fun" challenging project for me to solder up, and if I mess it up, I'm out $1.50 😀 ha ha
It really takes concentration to route the wires correctly, but I can usually pull it off if I don't rush thru it...
https://www.futurlec.com/Protoboards.shtml
Wide Range of Prototyping Boards for Building and Testing Electronic Circuits
perfboard with plated through holes is worth the extra cost, in my experience. i found soldering on the single-sided stuff very annoying
Agree, I've used both, and I just really don't have trouble with these.
Is their any intrest in doing a project or hacknight meetup? I'm part of a makerspace (fatcat fablab) in NYC and could host it. Mostly just wanna chat with some irl about circuit python 😆
This might help https://www.adafruit.com/product/73
most of us aren't in NYC 🙂 . There is an #events channel if you advertise it at the makerspace and then want to spread the word.
The moon is also drifting away from Earth, so at some point there will be a "final" total eclipse. A couple million years from now presumably. Then annular from then on.
super old news at this point but our house was at 99.5% totality so we had to drive south a couple of minutes to see it... totally crazy sight
I suppose that's why people thousands or tens of thousands of years ago placed more importance on it because it was a much more significant event.
yeah this one was the most "total" we will see for some time

What an interesting year of celebrity deaths, OJ died
🧤
FREAKING FINALLY
https://arstechnica.com/tech-policy/2024/04/starting-today-isps-must-display-labels-with-price-speeds-and-data-caps/
O_o they didnt have to tell you the cost before?
No
And an industry lobbyist group was fighting the introduction of this rule every step of the way.
how can you bu y a service without knowing what the price is
if it's the only game you got (aka redlining)
up here we know exactly how much we are being ripped off up front
if i go sign up for internet and it says $99/m... thats the price i pay (plus tax of course).
and you are saying in the usa this is not the case?
shudder
It isn't. You have to understand that most of these ISPs have regional monopolies.
we have 3 isps in the entire country that run everything
they charge $100 for 50 mbit
but they do still have to list the actual price
they tack on all sorts of little "service fees" -- there are a couple of options in certain areas where it's almost like competition, but it's only in urban areas where there's a lot of density (read into that what you will 😈 )
The entire industry is kinda messed up.
https://arstechnica.com/tech-policy/2024/01/cable-firms-to-ftc-we-shouldnt-have-to-let-users-cancel-service-with-a-click/
https://arstechnica.com/tech-policy/2024/02/cable-tv-companies-tell-fcc-early-termination-fees-are-good-actually/
they have their sweet local monopolies and will milk all the $$$ out of it they legally can (which is a lot, given lobbying)
Sometimes you get lucky with a small local ISP who actually provides decent service
I pay $75/m for symmetrical gig service. Great uptime, support is local.
The network engineers are super cool too
Yep, I have symmetrical 300M for $40/month. I could get 1G, but it'd be another $20. I'd probably buy it if my apartment complex didn't force me to pay $25/month for "valet trash service".
Ew
They pick up garbage six days a week. I put garbage out maybe once a month.
My townhome community just sucked up electrical and gas service into the lease portal.. I’m not a fan
“It makes it easier” and what they mean is, they can charge an extra fee for including gas and electric
my wife is a stupid good negotiator and we've basically got a flat rental rate for the next 1-1/2 years
I get that some tenants don’t end up changing over electric/gas service to their own name when they move in.
My rent isn’t going up for a second year in a row which is surprising
But they won’t lower it to be what they charge new tenants. 🙃
fun thing about electrical service: there's a guy that used to live like about a mile away with the same name as my wife and SPL had it screwed up for about 4 months
💀
Electric is separate for me and I don't get gas. Water is charged through the rental company though.
Of course, PGE has been rapidly increasing their prices. Up 18% over the last year or something like that. I'm single, live in a single bedroom apartment, and am either at work or asleep most of the time. My electric bill a couple months ago was nearly $200. Now that my heater is off, it's about $80.
Here if you got a tv or something that may serve as a tv, you need to pay a possession tax, which goes back to a ""national"" tv provider which is called RAI, which is collected when you need to pay for utilities bills, because people where obviously evading it
I Don't even see Tv, yet I need to pay some oligarch, because I may see their trashy services. Ridiculous
Totally democratic
Very happy with that. ☺️
Next up.. I'll have to think about adding some lighting. 😎
is that some sort of lego?
Fresh PCBs from JLCPCB
hey guys, i'm new to this server. i want to ask about the wiring between raspberry pi and arduino. but i have the motor driver l293d that will take all of the pins of the arduino. how can i connect the raspberry with the arduino?
What are you connecting to what, and how, exactly?
Which arduino? Which Pi?
arduino uno, raspberry pi zero wireless
- motor driver L293D is connected to arduino uno.
there's no more digital pins available to connect the pi with arduino
You can use the analog pins as additional digital pins
What’s the connection for? Is it something you can use the usb serial for?
i really don't know, there's an OLED display that works with I2C, is it okay if i worked with UART to connect arduino with pi ?
UART does work as well, if you have the pins available.
yes i have available pins for it
it will be okay when i will use the display OLED on the pi?
If it's an I2C display, it shouldn't use UART. I don't see a conflict, but that doesn't answer what your goal is here...
it's just i read that if one of the components uses I2c then the pi should be connected with I"C to arduino. and i'm wondering what should i use, cause some components use I2C and some use UART
Samsung is starting to put self promotions in my notifications 🌚
If you're proposing to share a set of pins to do both asynchronous serial communication and I2C, that won't work. However, if you have an existing I2C port, you may be able to make one of the boards act as an additional I2C target in order to transfer information (Seesaw style)
It is indeed a Lego kit. ☺️
i googled it. its cool, but i dont see a spec of "lego" on it.
its pretty cool otherwise. seems huge
There are a few main lines of Lego products these days. The original bricks, the Technics ones (which that is), as well as some special purpose ones like Bionicle
My last Lego build was also Technic based. Now I'm working on controlling it with a Pi
ooh nice
That's ok.. the original GT40s were built in Slough, England.
ha.
the newest one is almost entirely canadian. developed, designed, made, almost every part. but it gets called american cause ford
:/
A friend of mine has one, he took me for a ride in it, it was a blast
Canada is part of North America
shush
hehe
ive seen lots of the previous one. not many of the new one
I worked close to where the old Lola workshop was located.
The building has long since been demolished.
and of course originals and kits pop up
I do brick builds as well
Ohh, I should have the Camaro arriving today. 😁
Sadly not.
Real, as in it has a physical existence
the lego camaro "feels" a lot more lego like
Nice little fleet there. I have an Ecto and a Back to the Future DeLorean, they're fun builds
I was tempted to get the DeLorean.
And just let me say yay Sed and Awk. I'd suggest picking up Yacc and Lex, but they're not as much used these days
someone near me had a red delorean
Brooke Bond! 😅
Some of the parts choices are creative. The front grille of the newer Ecto is made of several dozen Lego skate pieces
It’s crazy to think that 12 years ago, downloading a 21GB game was not normal. It still isn’t super normal, it’s just flipped as to what side of not normal it’s on.
12 years ago, that was a huge game. Now that’s a pretty small game
there's an actual mazeratti dealership < 1 mile from where i live -- that stuff is wild
The Atari 2600 games normally fit in 4kB (but could be extended to 64kB with bankswitching). Even the mighty Atari 800 could fit big games onto an 88kB floppy.
I really didn’t understand well. Can you clarify for me more please
i don't have a size for it, but i played the heck out of https://en.wikipedia.org/wiki/F-15_Strike_Eagle_(video_game)
F-15 Strike Eagle is an F-15 Strike Eagle combat flight simulator originally released for the Atari 8-bit family in 1984 by MicroProse then ported to other systems. It is the first in the F-15 Strike Eagle series followed by F-15 Strike Eagle II and F-15 Strike Eagle III. An arcade version of the game was released simply as F-15 Strike Eagle in ...
I was trying to clarify what you're actually trying to do. It seemed like you might be trying to do asynchronous serial communications using the same GPIO pins that were used for I2C.
Oh no no, I was asking which communication is better, the I2C or the UART. Cause I have mixed components that some of them use I2C and others use UART
"Better" depends on your parameters. Both are capable of similar speeds, but I2C has a defined protocol for data transfer. With asynchronous serial (AKA "UART"), you generally define your own protocol. You can do full duplex with asynchronous serial, but not with I2C.
I have a 24GB update in my queue.. lol
There’s probably a large Helldivers 2 update waiting for me
If you haven't played for a while, perhaps.
It’s been a few days
It's too hot.
I'm thinking to make a space like suite, with an air conditioner backpack, powered by the nastiest type of fuel
what do you think?
any pipboy likers?

this could give you ideas for your projects
Turns out that a great way to get yourself to sweep the floor of your lab is to spill a dozen 3mm BBs. (I found 11 of them)
First of all, that looks like AI output. Second, it really depends on what you want to accomplish. Just keep in mind that the Uno R3 only has one UART, and that it is used by the bootloader and wired to the Atmega16u2 for USB communication.
that's chatgpt saying and i have a free UART of course, the pins 0 and 1 are for TX and RX
Those are the pins I was referring to. They are connected to the 16u2.
the 0 and 1 are free
i'm talking about those
So am I.
i didn't study to that extant to understand this. can you explain for me
Sort of difficult to show from my phone, but here are those pins in the schematic.
they're connected to what?
The TX/RX pins on the Atmega16u2, via RN4A and RN4B
but i'm not using any of those !
How are you programming it?
sorry, what do you mean? i'm not using atmega16u2 or anything else. the pi is going to be connected to the arduino by those 2 pins. that's all i know
When you upload a sketch to the Uno over USB, it is actually received by the Atmega16u2 chip on the board. The 16u2 then resets the Atmega328P (the chip your code runs on) and transfers the program to it via that UART interface.
You can use those pins for other purposes, but you have to keep in mind that every time the board is reset that it will check for incoming data for programming.
Also, you can't connect an RP2040 to an Uno without level translation.
this is just a prototype for a Uni project, not going to be defined perfectly. so what do you suggest to connect the arduino with the PI except the I2C ?
USB serial?
and how that will be?
Raspberry pi has USB ports, just plug it into one of those
just a usb canle from the pi to arduino?
Works for most purposes.
Klipper 3d printers use it that way.
aah ok thank you

Yes it was down with a 503 this morning for a short time. Learn and Blog were uninterrupted. The domain points at the store so it was mostly the store going down for a little.
I have a blog RSS feed and I usually get to the Adafruit site by reading one of the latest blog posts. I didn't notice the interruption because I wasn't shopping in the store or using the full domain name only. https://blog.adafruit.com/ was not affected. 😉
Finally! I think you are tge only other person I've encountered who uses RSS/Atom. It's an... underrated technology.
It's the most efficient way of consuming a lot of news. Some sites have 24/7 feeds with 20+ new blog posts a day. RSS lets me go through hundreds of potential blog post titles per day and read something that interests me. One of the reasons I love Adafruit so much is because almost every blog post is interesting, I read almost all of them.
Yes, and and it (mostly) eliminates The Algorithm™. When I read the news, I want to see the actual news, not a cherry-picked stream of "content" based on what Google or Microsoft thinks will generate the most engagement.
But the thing in that place you googled 4 months ago happened
What programming language are you using with it? If it's Arduino you can find help in #help-with-arduino If you're using Circuit Python then you can find help in #help-with-circuitpython or if you're using a Raspberry Pi or other Linux based small board computer you can find help in #help-with-linux-sbcs
Hi, I'm looking for an idea to make a small glass for my uv sensor in the weather station. I'm looking for a material that allows as much uv rays as possible to pass through (280 - 430nm) What material will provide it? I've heard that quartz glass is good for this, but the prices are very high and they sell it mostly to labs
I wanted to do it with an acrylic but it falls off because it doesn't let the uv light spectrum through at all
Aliexpress has many sizes and shapes of quartz glass for a couple dollars a piece.
I think I've found a solution. The old EPROMs had a small quartz glass window, maybe I can open it and get it
That's a good idea. Good luck.
Thanks 👍

Oh dear..
It's not Queen or Genesis.
I'm thinking about getting a couple of ESP32 boards with LoRa, to test Meshtastic. 🙂
I published a Gist of tests using a Raspberry Pi 5B-8GB with an Adafruit Gamepad QT and an Adafruit AHT20, using the Adafruit-Python-extended-Bus, Adafruit-Blinka and other modules. Also added logging info and data to two separate log files. See: https://gist.github.com/PaulskPt/ad9e39cdcb9aefc392f02be2fc83fd62
This year on Embedded World 2024 we had our booth in the M2M area. It is clear that cellular IoT is really growing and the technology is maturing. It is also clear that the suppliers are focussing on large volume projects only. The reason is that certification of multi-radio modules is very expensive and you need a volume of at least 50k products a year to justify the expense.
At the same time I believe that there are lots of use cases where cellular is a perfect fit but the volume only reaches between a few hundred to a few thousands of devices a year. I'm thinking of remote weather stations, remote device monitoring, pump control, vessel monitoring, scientific settings, road management, ...
Therefore me and my team have created Walter. An open source, fully certified (CE, UKCA, FCC, IC, RCM), multi-radio (LTE-M, NB-IoT, GNSS, WiFi, BLE) module. The module can be programmed in ESP-IDF, Arduino, Micropython and Toit. Because the module contains all RF circuitry and has a modular approval anybody can now design cellular products. When you design a carrier board for Walter you only need to do basic EMC + spurious emissions testing on the final product. Even single person and SME companies can now create and launch cellular products.
To accelerate the launch of Walter and spread the word we have launched a campaign on Crowd Supply. We need your help to make multi-radio IoT products thrive by backing and sharing our campaign: https://www.crowdsupply.com/dptechnics/walter. I would love to hear what you will build with Walter!
So that's a Lora module + esp32 + display right?
Yarp. 👍🏻
I ordered two. ☺️
And you can power that all through the usb-c port
Seems so.
It also has a battery plug and a lithium charge circuit on board.
You can increase the range substantially with a different antenna. The 915MHz ELRS / Crossfire antenna are relatively inexpensive, rugged and tuned to the right frequency.
I thought you could set the frequency, but.. ehh? Lol
Just don't use stubby antenna, right? 😅
Which? The one that comes with it in the picture? It'll work, but be of limited range.. the little copper coil on the board is the wifi antenna.
i think you can't do that
I'm sure I'll figure it out soon enough. ☺️
It might end up being my first shed project.
Well, I cancelled my first order for the 433~510 version.
i was planning on getting a bigger antenna for it, something like this
oh also, did you check the regulations in your country?
The 863~928 version seems more popular.
HA! No. 🤣
ah
hmmmm
eh i dont think anything bad should happen
what could possibly go wrong
(i am not a professional and my advice should be taken with caution)
Lel
check there 👆
in my case it was
huh i was sure it said 433 last time i checked
anyways with help of danh i found the documents for the regulations of these things and that also listed the available frequencies, in this case my country allows 433MHz and 915MHz
I can only speak to North America with assurance. 915 is definitely the right frequency here.
I’ve made it to CNX Software lol https://www.cnx-software.com/2024/04/16/icyblue-feather-v2-lattice-semi-ice5lp4k-fpga-adafruit-feather-form-factor/
Only issue because they used the Hackster.io article, I reduced the price from $74.95 to $61.95
Ouch. It was probably slim margins to start with
$28 in parts when I can product a lot, trying to cover development of software, have enough overhead for replacements if bad boards. Right now, at the scale I can buy parts, maybe 40-45% margin not including labor
But if I can sell more, hopefully I can get the margins to a better level and I can actually order enough to get the steep discounts that tinyvision.ai gets
They sell similar hardware for $30, just not as a feather
But they had the $$$ to make the volume purchase necessary
The Lattice Featherwing might be trickier in that respect
They make it sound very official.
with the introduction of V2, the company claims that all previous issues have been resolved
I can just imagine the PR department of your company putting out press releases like that
😉
I do make the claim that the bugs have been resolved 😉
blue pill :D
i have one.. still need to figure out how to use it
Funny thing as I circle back to this, this morning. I had plans to issue an errata for IcyBlue because of the ambiguity of saying you fixed bugs without specifying which bugs lol..
Just some small bugs:
-
Missing 12k resistor to ground on the REF pin of the FT232H so you can actually use USB2.0 speeds and also properly use iceprog.
-
Stack up of the original had 2 layers which when operating above 12MHz in the pins could cause some weird sagging.
Changed to a 4 layer stack up
I can understand wanting to stick with 2 layers but sometimes it just isn't going to work
Fortunately these days, the cost penalty for 4 layers isn't as large as it used to be
Yeah, 4L is just about the same cost as 2L
I’m moving a lot of my designs to 4L
Even 6L is becoming very affordable
It does give some nice freedom
Yeah, not having to worry about a patchwork of ground connections is one big perk
Do you have the specs handy for the clock crystal (or oscillator)?
I still may hot air off the existing one and upgrade to a higher precision one for one of my projects
So I don’t actually provide a global clock, though I’ve thought about adding one on the variant with the UP5K because it can go up to 100MHz
Normally FPGAs have dedicated clock pins. But if one of those is routed to an I/O pad, then I'll just supply the clock that way.
Yeah, there are 3 global clock pins on the LP4K
I believe 2 of them are available on IcyBlue, all 3 are broken out on the feather wing
It sure looks like there's an oscillator or crystal tucked underneath the LiPo connector
Ah, that’s for the ft232h usb bridge
Ah, that makes sense. I'm also amused by the presence of a 0Ω resistor (normally you don't see a lot of those for routing purposes on 4L boards)
Some boards like the iCEStick use a TXCO and supply it to both the FT232H and the iCE40 fpga
I also need to look up whether the SPI block can be used as a target
Once the FPGA is set up (cdone asserted), the SPI pins can be used as normal GPIO or for writing to the SPI Flash
Ah. I'm hoping to use the FPGA as an SPI peripheral. But I may have to just build that out of generic logic (which isn't that hard, really)
There are two hardened spi IP blocks
Right. I'm hoping I can use one of those as a peripheral (instead of host)
I don’t see why you couldn’t, there’s probably a good example out there for it
I also need to learn how to use IP blocks like that in IceStorm
I was thinking of using the heart and gift emoji then I found that one
I will probably update this example to have the SPI peripheral pins be on the edge (ones broken out)
But that’s super easy to change in the io.pcf file
Yup, no worries there. It is going to be cool if I can use this to implement my Stroboconn project
😎
I’m also working on some softcores to run
I have a somewhat functional 16b pipelined CPU
And I’m working on implementing an AES encryption example as well
I was toying with the notion of implementing an MC14500B (realistically I could probably find some out there with a brief search)
People do some wild stuff on FPGA
My other project is recreating the Atari Music Visualizer
Ohhh
I have the schematic for one of the Atari systems that was made in 74 series logic
Here’s the first page
TIA-1A
It’s the television adapter
Not the actual Atari itself
But still pretty cool
you can do amazing stuff with 7400-series logic. just takes a whole lot of chips to do anything useful, though
Yeah, so true.
I work with a guy who worked for Evan’s and Sutherland back in the 80s and designed some of the first hardware shaders used for 3D graphics
Really cool guy
Before Evan’s and Sutherland got parted out to Cosm, Nvidia, et al.
Err, No! Evan's sell bicycles!!
😛
🤪
Anyway, this guy also went to Oregon state with the CEO of Nvidia. They were friends in the college days.
Pretty wild.
The joke, for a while, was that all of the SGI'ers ended up at Google because they wanted their old desk back (the buildings in Mountain View that used to house SGI were leased to Google as SGI shrunk)
i worked in a building many eons ago that had been part of the Datapoint (https://en.wikipedia.org/wiki/Datapoint) complex
how do i now (before) ordering that i have the correct bearing? (i want a bearing that spins rlly long but i got a few here on my desk but they stop spinning in like 3 seconds)
You’ll want what are called “frictionless bearings.” Obviously there’s still friction, but they’re supposed to be ultra low friction bearings
They’re usually used on things like skateboards and roller blades
Glad we could help you get your bearings.
Super REDS are designed from the ground up to be the best bearing on the market at this price point. What Super REDS are not is a REDS bearing with just better super finishing (surface polishing). Super REDS are a superior quality bearing, using higher quality steel races, better quality and grad...
This would work right
Screw Amazon here a lot of things are expensive
(Where I live)
lol
what is the difference between bearings that are yellow and red?
One is red, the other is yellow. 😛
Gawd knows.. maybe they just didn't want boring colours.. or it's some indicator of.. something(?)
maybe its the clearance ors
but they still rotate long
wich means
iam gonna buy the cheapest
I was actually being sarcastic with that link....
I didn't even read the messages before that. 😛
..
I wasn't taking wirehead's message literally.
(deleted because that was a bit of a veer that only wirehead was gonna get)
github must be slammed today.. trying to submit a PR to Circuitpython and the checks are still queued after 15 minutes..
Soo, bit of a weird question I figured people here could help me with: Does anyone remember the xneko/oneko program? The one with the cat avatar that followed around your mouse? (see attached)
I remember coming across some ASCII art of this exact cat sitting on top of a (CRT) computer monitor. Does anyone know where it was from, or even better happen to have it?
Sounds familiar but I’m unsure where I remember it from
Google only seems to return junk/spam results, or I just can't think of the correct query
I found this video https://m.youtube.com/watch?v=VaV9giuY-UQ
In this video, I show you how to set up a really cool program in Ubuntu 16.04 LTS that creates a cute animated kitty to follow your cursor around the screen.
The app is called Oneko and is free to download via the Ubuntu Software app.
Download Ubuntu 16.04: http://goo.gl/pqpyJD
Ubuntu 16.04 Tips Playlist: https://www.youtube.com/playlist?list=...
To clarify, I am not looking for the xneko program itself; I am specifically looking for the ASCII art of this cat on top of a computer monitor
Oh I see
Though if you want a collection of its various implementations over the years, help yourself:
Probably similar: https://github.com/GuidoFe/oneko-optional-cursor
They have bitmaps for the neko
I think the original source tree has them in xbm format too
I remember the days of cursor pets though, lots of fun
I think there was also a sheep....

Anyone see this linkedin post about adafruit request to make a lorawan network server.
https://www.linkedin.com/posts/jeremy-ellis-4237a9bb_adafruit-techeducation-stem-activity-7184956118496952320-eLyg?utm_source=share&utm_medium=member_android
Welp, I’ve joined the society of dads who swore they wouldn’t buy a minivan
I mean, minivans are a very well optimized design.
Not in my opinion. They're basically built on a light truck chassis to dodge a variety of regulations allowing them to be built cheaply at the expense of safety.
My car is 14 years old, and has developed a fault in the feedback circuits of the climate control actuators. I could replace the car, but I think I'll just build a climate control computer that doesn't care deeply about knowing exactly where the actuators are.
Or I'll just install a line of toggle switches and operate them myself
Hehe
I just needed a car to seat 6
My wife will mostly be driving it so it had to be something she wanted
Hmm, blinked at the price of ₱570.60 then realized that's Philippine pesos, which is about US$10
It would be cool if there was a single global currency to make trade/overseas shopping more transparent
In my opinion it would be even cooler if international shipping were reasonable (in speed, price, reliability, predictability, and ease of use)
Yeah, $26 for a small box of PCBs and a stencil just feels like a lot
In theory, it would be convenient. In practice, I wouldn't want a single global authority to have that kind of power.
My vague idea from when Bitcoin hit the scene was that the whole mining thing was silly and you'd be better off converting a basket of different world currencies into a singular currency unit, but I can come up with a bunch of reasons why it doesn't work.
Could be governed by a board of elected representatives from each country, representative count determined by GDP.
Sounds like the world economy would be dominated by China and the US... Good news, we're already there.
lol@false assertion
Yep, it'd be horribly broken as a result. And smaller/poorer countries would get absolutely screwed (even more than they are now).
Or just do 2 representatives per country regardless of GDP
Then small/poorer countries would have outsized control compared to their impact on global gdp
But I digress in order to stay away from political discussions.
changing course, y'all might appreciate this: i was having some issues getting a servo connected to some lego gears to turn to the correct angle
there were two things here:
- the servo in question has a pretty wide pulse-width and actually turns > 180 (easily settable, so just "data')
- i was using the wrong gear in my gear ratio calculation, so my expectations were completely in error
😆
Always double check your part compatibility, not all soldering irons are built the same way.
I bought a T12 iron which only takes T12 bits
i only thought of that after buying the bits
lel
Anything that uses Hakko tips is the most widely used. Even if it's a different brand if it says it uses Hakko tips that's a plus. They're very easy to find and compatible with a lot of different soldering irons.
I never understood the hype around Hakko soldering irons until I bought one. They heat up and are ready to go in like 15 seconds. They stay the same temperature so there is no temp drop during soldering like other cheaper brands. I used a $20 soldering iron for a decade and was quite happy with it. Now that I've used a Hakko for a couple years I definitely prefer it.
Think I might have finally figured out why my irrigation pump is turning on and off. It took removing 8 wires and 12 screws to get to it which is why I put it off. I thought it was probably fine... it was not fine.
The relay contactors pads are almost gone and burned up. Then I figured out it's an 18 year old relay. Time for a replacement.
The high resistance contributed to frying the wires on the well pump. I've replaced the wiring and conduit but was still getting pump latching issues.
What I had to unwire and remove to get at the relay. I'm glad I found a problem with it because if it was fine I would have been even more confused what the issue would have been. It's a non-serviceable part. There's no way to clean the contacts and wouldn't even bother since they're almost gone and toast anyway.

stop breaking your house
😛
says the person that litterally shamshed their house yesterday 😛
that does look like it's somewhat controlled
Is that solid concrete?
What in the heck is that? Ive never seen something like that before.
and those issues were not my fault. They came with the house… and plumbing issues.
hehehe
its concrete block but they are filles, so yes, solid. i cut it with a big concrete saw from both sides, but that remaing 0.24" REALLY held on. took many hits with sledge hammer to knock it out
the think in the space left behing is a toilet tank frame. for a wall hung toilet

Called Spy Pet, the service's creator says it scrapes more than ten...
i happened to have a spare, but also it takes up liek 9" less floor space
I KNEW IT WAS REAL!
i kept being told no, discord doesnt do that
but i type is "new table saw" here and i get a firkin ad for on 10 mins later
so, who's the bot? hmmmm
(One of my friends purchased her first house and I have been teasing her about this)
ha
given ive literally replaced every single stud and am about to replace the floor, joists and all... its pretty valid
thats why im turing the shed into a tiny hosue with that bathroom 😛 so i have a place to live for a few months
haha
something like this
its actually a really nice tiny house. nicer than the existing how is right now hahahah
foundation for the little bump out on the front "outdoor" kitchen
When you are done, the main house will be a ... smashing success.
ha
well, a smarter... i mean richer person would knock the house down and make a new one
but how is that fun?
(actually ripping it down would cause many issues with code, it is too close to the fence and road)
I mean there's that whole thing where the new house gets built using modern cheap disposable materials
id live to build the house like i did the shed, but it would cost way too much
the shed is all engineered steel
I think it would be fun to build a house out of 2020 extrusion.
"fun"
I may have a weird idea of fun.
wiring be fun!
its wired except the lights and the new kitchen. so thats good.
the panel will connect to the main house with a 30A generator cord for now. $250 vs like $4000+ to do it underground 100A
also there are trees in the way
my friend makes oil field enclosures for equipment, which are basically steel sheet metal houses
House of Theseus
ha. pretty much. the foundation, and SOME of the outer wall will be left
Well, when you get it back together, even you will be floored.
trying to come up with a construction pun, but I'm drawing a plank

Hello people. Engineering student working on a final project. We are trying to create a switch for the baby einstein take along tunes toy. But we are finding it difficult trying to find where to solder the wires to the pcb in the toy. do we have to desolder the pcb from the plastic housing in order to solder it on the back or can we just surface solder from the front.
and if we can, where?
The pcb shouldn’t be soldered into the plastic housing…? What do you want the switch to do, exactly? Is this a power switch?
Oh I see what you meant by soldered in.
That’s interesting.
please do not cross-/multi-post -- if your question is not appropriate for a channel, you will be redirected
Ok. Sorry about that
I want our switch to change the song. We accidentally wired a switch to the power button on the toy. But we wanted to make it change songs. Basically do what the big colored button on the toy does when it is pushed
Are you just adding a button to some other place on your toy? Follow the traces of the button contacts shown at ~6:30 in https://youtu.be/FT0PbVF_aeY?si=keHQhs3dwnfuYh9E&t=397 and I think I see two round pads you can solder your wires to. If that's not the right trace, you could also gently scrape the soldermask off the traces to expose some metal to solder your new button to.
The wording of "switch" however, makes me think you're not using a momentary contact like the PCB was designed for. Keep that in mind when you're connecting your switch.
We did that. And it works!! We are a little concerned bc we used a very small amount of solder on the little e shaped pads and the connections might not be as secure as we’d want. But we will go back over how to strengthen the connections next time we meet. Thank yall so much
What does a board need to be considered "industrial", is it just adding the word industrial to the name of the board?
I would think protection against power surges, better environmental protection somehow, maybe wider temperature range. If there are external connectors, industrial-type
as opposed to "pro", which has a lot less meaning'
i'd suggest reading the specs of "industrial" boards from real industrial suppliers
industrial usually have different bios types as well, allow custom splash screens, have lvds panel connectors, etc. its mostly about targeting the application.
also life cycles are 10+ years
Life cycle was something i already thought of, you want a device like this to last for very long
And in the case it fails to be easy to repair or replace
In theory the DX32 should work for this since i made it with the intention of being as simple as possible
industrial buyers expect you to have replacement boards 10 years from now
Mah I don't see that much of a difference from "professional" or consumer grade equipments.
They usually just cost a lot more, and have long lasting warranties... Which I haven't had a first hand experience yet
pro just means fancy high end features
industrial means what it says. it is for industry use
I came up with the name: DX32I "industrial"* (i have no idea if this werks in an industrial use case)
Fancy keywords to the same (mostly) product, with minimal differences to target """different""" markets
warranty and such would also be required, methinks
Slap a sticker on your boards that says PRO and charge more for it 🤑
sometimes it might seem like a worse board for 9x the cost. but it has some specific things industry needs. like 9 serial ports
Looking at actual plc boards a lot of them feature large serial ports so thats going on my board as well
and support. if my atm flips out, you better be out in an hour to fix it
In any case better getting the products sheets
right to repair also factors in. where apple will try to hide specs from you, industrial suppliers are often fully expected to supply schematics and bom
serial is still used a shocking amount
Ik
but often it is done on an RJ45 connector
and not a db
my cnc spindle drive for example has rs485 and modbus abilities over an rj45 connector
Yarp.
Today I learned about Wigner Crystals
Something theorized and recently confirmed by scientists at Princeton University
Basically when electrons are exposed to an electromagnetic force stronger than their own repulsion force and energy level they space out as far as they can into a tight lattice
Creating essentially an electron crystal
Pretty neat
Electrons—these infinitesimally small particles that are known to zip around atoms—continue to amaze scientists despite the more than a century that scientists have studied them. Now, physicists at Princeton University have pushed the boundaries of our understanding of these minute particles by visualizing, for the first time, direct evidence fo...
As opposed to Winger crystals which is what you get when you've got jewelry and a hair metal obsession.
i was going to continue this pun with old WW 1 german plane engines, but that's a banned word 🤣

Why do sick people need to go to work & force all the windows to be close.
Why do they also need to force me their ridiculous rules as no masks and no work at home so I can have a paycheck
Now I am sick. After like 5 years that I wasn't getting any flu like symptoms
id have thought your country would be all masks all the time at this point
Yeah I'll delete it, if I even have to question if it's inappropriate here its better to err on the side of caution.
Quite the opposite, everyone is without one.
I started to stay without a mask for getting a job because people were looking at me like I came from the moon
I honestly thought you meant people who close all their windows on their PC before shutting it down bothered you. Couple hours later read it again in a completely different way.
Hello. I am new on pi. My thesis is all about connecting arduino and rpi via nrf24l01. Arduino needs to send data to rpi5 and rpi5 must create a ui where it will show the data there. Before coming in here, i accomplished the data collection and transmission between 2 arduinos(uno and nano accordingly). Now because i am new with rpi, all the examples that i tried to use as a base before building on them are not working. I read that rpi.gpio library is not working. I discussed this with my teacher and he told me to check out circuitpython_nrf24l01. I tried using the simple example, modified it, wrote a simple code on the arduino to transmit just a hello world, but it still won't work. Is anyone familiar with using nrf24l01 on rpi with circuitpython? Also i am not familiar with python in general, so is there anyway i can write the same code as i do on my arduino(c++)? Btw i am not using ssh, i have it plugged in on a monitor and i write code on Thonny because i am not familiar with terminals.Idk where i should write so i wrote here and in #help-with-projects . Thank you in advance.
I love that even though now that most components and whatnot are generally very available, I still get emails from brokers who bought up huge supplies hoping to make a quick buck during the parts shortage
Every time i want to send a message here i have to re-read it multiple times and check filenames and whatnot
Ive already been warned for some words that i didnt know were not allowed and im not risking it
I dont want to get the boot

Also, keep the T word banned
in general, all vulgarities are banned
Got it
sometimes the censorbot goes rogue and blocks weird stuff.
it allows non-alphabetic characters: *badword* matches ba/dwor.d etc

In last terms update discord sneaked in forced arbitration clause, which is one of the things that no sane person should ever accept in any situation.
Everyone must opt-out ASAP:
**
Opt-out. You can decline this agreement to arbitrate by emailing an opt-out notice to arbitration-opt-out@discord.com within 30 days of April 15, 2024 or when you first register your Discord account, whichever is later; otherwise, you shall be bound to arbitrate disputes in accordance with the terms of these paragraphs. If you opt out of these arbitration provisions, Discord also will not be bound by them.

You automatically opt in by being on discord it seems
Yeah, it's still legal in 🇺🇸 unfortunately.
yeah, so thats invalid
yes, so it seems
forced arbitration in general, but also "opting in" people on things like this is also illegal in canada
the telecoms used to try to opt peopel into lots of things
rossmann posted something on LG, and i went and got their canadian clause, and it was worded a bit different and had at the top "where applicable by law". so their lawyers are trying to wiggle around
what they seem to hope is (you) dont know the law yourself and just do what they say
There s any one work with assembly programming in microcontrollers ?
M looking for semeone who is working with ASSEMBLY PROGRAMMING IN MICROCONTROLLERS EMBEDDED SYSTEMS ,
@celest latch you'll get better results with a specific question... with an open-ended request, folks aren't sure what they'd be' getting in to
i want to Write an assembly program that simulates a single-digit counter (0-9) that:
increments on the rising edges of RB4 (by interrupt);
decrement on the rising edges of RB5 (by interrupt);
automatically initializes if its value reaches the maximum value of 9;
it can be initialized by the operator using an interrupt on RB0.
@celest latch can you tell more about: what board are you using? what programming environment?
logiciel : MPLAB , PROTEUS
assembly coding
any idea ?
That still doesn't provide the right information. MPLAB is just an IDE released by microchip, and it supports multiple architectures. For assembly, you need to specify the exact chip you are using.
And it would also help to know why you need it in assembly specifically.
Guys i have mini project who is has 3 steps , write assembly program who work for segment countaing from 0 to 9 but using timers with interruptions : 1-increments on the rising edges of RB4 (by interrupt);
2-decrement on the rising edges of RB5 (by interrupt);
3-automatically initializes if its value reaches the maximum value of 9;
it can be initialized by the operator using an interrupt on RB0. This is my circuit on proteus so doing my efforts , any help ?
Mine also just arrived
@glad ruin
Sorry, I don't have an answer. I'm not familiar with PIC16 assembly.
@celest latch why assembly?
is this a school project?
no trust me university
we start with assembly
and we will go to C next week
well, we don't want to do your homework fo you
i dont want you to do my homework
i have the script its working on my circuit but i have some problems
so no one can help me
its not homework its mini project , i need to do manually after finish from proteus
any help ?
i can send my script
none of us know PIC assembly, sorry
PIC is very unnapealing to me, specially because of the development software
Tried looking for something like that on aliexpress but I don't think I've found one, is there a specific name for that arrangement
I did get some Lora boards though
Which ones?
I've ordered the Lilygo T-Deck to go with my Heltec V3s. 🙂
Fair... Did you look up the frequencies and find out which one you need?
Mine is the Heltec V3, 868MHz (863-928 range).
There's another in the lower range; 433-510, but those don't seem to be as popular in the UK.
Can't speak for the UK, but the FCC doesn't allow for unlicensed use of the 433MHz band in the US AFAIK.
General inquiry... I have a few wifi boards that are http servers delivering my formatted HTML to my PC. They all work fine, except for a Pico W - the issue is since the settings.toml had the standard CIRCUITPY_ settings, when I go to the specific IP address in the browser, it gives me WebWorkflow for the PicoW, NOT my html webpage. I've tried not using the CIRCUITPY in toml file, but then I get "unable to load" the page.
My other boards, such as Metro ESP32S2, come up with my html.
Not a huge deal... I've been experimenting for a while and not making progress. Don't really "need" to do this with the Pico W... it's pretty limited on memory anyway 🙂
Are you perhaps using the same port for your server and your web workflow? Try changing the port number in your code or your settings.toml file. To access your different pages, 192.168.XXX.XXX:[port#]
Theres a meshtastic node a couple blocks away from my house but sadly there are multiple buildings between them and me
This is kind of a paradox, its more likely to find meshtastic users in a city because of its large population, but because its a city there are more buildings that block and interfere with the signals
Maybe i beed a bigger antenna
Yeah something like this
Thanks. I just found some of my confusion - still new at the httpserver stuff.
In the line of code server.start(str(wifi.radio.ipv4_address))
it prints a message to REPL that I'm not specifically doing myself in the code... and it says: Started development server on http://192.168.0.xxx:5000
I admit I didn't pay much attention to this before. Anyway, if I enter that complete IP, with the 5000, I get my html. If I change to port :80 like in my settings.toml I get web workflow! Amazing. You can flip back and forth.
Don't know where the 5000 comes from, but this is working for me Thanks!
Glad to hear you figured it out! Port 80 is generally the default port used by browsers when you enter an ip without a port, so whichever page you prefer to be “front-facing” will generally be the one using port 80. You can define the port in your server.start() arguments; by default the port it uses is 5000.
High everyone. I’m trying to determine if I blew up my adafruit m4 metro airlift lite board. When plugged into usb to computer the bootloader mode seems to work but once in normal mode the RX and TX lights just stay solid and it won’t accepted code. I have tried flashing the bootloader and that seems to work. We started experiencing issues after we might have tapped 6 v into the SDA and SCL pin I’m not sure if it actually hit or not.
If I can flash the boot loader is the board likely fine?
Hard to say. Does it show up as a com port when you plug usb in?
Yes while in bootloader mode
I do also wonder if we accidentally killed the metro if it would be possible to kind of zombie it using another metro (non airlift) and just wiring to WiFi module pins
We unfortunately do not have time to wait for a new airlift to come in from shipping
Yeah, it’s possible you killed it. The m4 on there is only tolerant to like 3.6V
Dang. What about trying to access its airlift module from another metro?
Have you tried some simpletest examples to see if some of the physical pins work other than sda and scl?
I did try to load just the blink example but it failed to upload.
Do the RX and TX lights monitor USB traffic in addition to other traffic? If they are both solid that would mean it wouldn’t respond to an upload I guess? I don’t know it’s weird because the bootloader mode works perfect at first
I’m not sure, you could see how they’re hooked up in the schematic on the primary learn guide
Sounds like you may have broken GPIO I general. For instance, blink might have loaded but the LED in is fried. Khoi could try loading CircuitPython on it and see if that comes up with a CIRCUITPY drive. But if GPIO is fried you won’t be able to talk to the coprocessor
The LED does turn on it’s just always on lol
Honestly I had no idea what I was looking for, the ones I got are 433mhz.
You might find 433 stuff, I don't know.. depends on your area.
It's worth trying both.. they are cheap.
hey hows it going nowadays? Rainy day here today
we got snow momentarily
Uhhhh its still hot here in chile
We had rain some days ago
Idk climate change is wild
The Sahara used to be a grassland full of animals. I don't want to go too deep into scientific theory, but it's been said empirically that humans adapt to these events (the survivors) and Improve.
I still need to fix my car A/C and I don't have the tools
Mann im starting to believe the avocado industry has developed technology to extract humidity from the atmosphere now to irrigate the plantations
They do that in tibet also
Youre lucky, i dont even have an ac
Theyve drained a whole lake for avocados
Isn't that the gist of cloud seeding, I know they do some humidity extraction in the wealthy gulf states
Greed of selling avocados is what drives them to decimate the environment, the fruit costs more than a dollar a piece retail it's a very high priced item
Same thing with lithium, and gold before that
Coal also
Huh, so my wacky conspiracy may have some truth to it
They're already looking at annihilating the ocean floor to extract more rare earth metals
Yea well your country is mineral rich
Chile again, same thing happened with saltpeter, same will happen with copper, and then lithium
Chile is mineral rich
Super mineral rich even
Yeah exactly they will be plundered
All these iPhones, and Tesla's and all these yuppy toys come from remote country components often times with bad labor practice
Yeah I am all for documentaries
Its only in spanish i think
Have you heard about Toyota 1:6:90 rule?
Let me get it right first and double check literature
1 fully electric car can make 6 plugin hybrids or 90 hybrids non plugin
Fully electric cars use so much materials that are scarce that it's more impact to phase out ICE with 90 hybrid engines such as their "Hybrid Synergy Drive" rather than full electrical which is wasting materials
So 1 Tesla used the rare materials of 90 hybrids
The only word i can use for this is not allowed in here... but its crazy how inneficient fully electric cars are in their current state
My 1.8 L gets 38 mpg on the highway but a hybrid gets like 56 I think?
Atkinson cycle engine it's really smart
The entire hybrid synergy drive was invented in early 1980's by California engineers
unfortunately they adapt when most of the population dies off. we survive "barely". with our expectations of climate in the near future, it is mostly going to be about feeding everyone as our normal food sources get disrupted.
anyhow
"good luck with that kids"

if i was in charge of the world (ha) id would make all cars electric, with modular fuel supplies. a gas generator could be one supply and as batteries, hydrogen, and everything evolve you can just swap them
the actual electric portion of the cars is very good and has been for a long time
If i was in charge of the world..... i would make a giant mech and start stomping on the houses of people i dont like
But i would also put nuclear power plants everywhere
Start promoting the use of public transport instead of cars
Make cities greener and more walkable
Giant cool mechs
Vote me 4 president and if i get elected u get a free mech
The moon is looking nice as always
If you zoom in it looks like a cheeky face on it
Here it is circled if you didn’t initially see it
its just a block of cheese on a string
8051 architecture still going strong, though slightly younger
It's also a microcontroller architecture, rather than a mivroprocessor like the z80 (itself originating from the Intel 8080, with a number of enhancements).
Hello night owls
I am looking to buy a good quality AC millivolt meter for audio purposes
All the recommendations are for old audio equipment
Like the HP 400 series
Anyone got any ideas of where I can find something digital
Depends on how you define "quality." When it comes to high precision sensing, the analog equipment is technically superior due to its lack of switching noise. Anything digital has to design around the fact that clocks and other fast switching signals can potentially induce noise and ripple at a millivolt level, which could be mistaken for a millivolt AC signal.
I know digital equipment for this does exist, but I don't have the experience to tell them apart from the cheaper noise-inducing ones.
Well my issue is
Sure the analogue ones do have less noise
But they will need me to
Go through the entire unit
Replace every capacitor
Sometimes even ICs
And recalibrate each unit
I have these guys here that I'm doing that to
I was looking at the HP ACMVs
Same era as those
They are from the late 60s early 70s
I love old gear but I wanted to see if it was possible to get something slightly newer
Then the next question is how precise and accurate do you need your measurements to be? And what budget are you working with?
Do you need any additional functionality like PC-connected logging or automated measurements?
nope
this is to calibrate old audio equipment
im okay with older gear just not 60s old since
they have so many unobtanium ICs
at least 1% in the 40hz to 20khz range
within 2% would be more reasonable either works
This is really interesting
Imma do a psa for all adafolk
There is a site known as spy.pet that has been scraping massive amounts of messages from discord servers
This tool helps find spy.pet bots: https://kickthespy.pet/
Ive already checked if this server had any bots and fortunately there are none
@thick wind i found ones that work and are like
20 years newer
just waiting for them to be posted for sale
Kikusui AVM23R
or
Kikusui AVM25R
KENWOOD vt-187 or 186 or 185
and
GW Instek GVT-427B
i ended up getting a Kikusui Model AVM15
which was made in 2001
got a really good deal
Hey everyone! I'm new to the community, and I've been exploring CircuitPython's design guidelines. While reading the "Design for compatibility with CPython" section (https://docs.circuitpython.org/en/latest/docs/design_guide.html), I came across a recommendation stating that shared functionality should use the same API as CPython. Intrigued by this, I decided to develop an application that compares the APIs of two different Python modules.
The app offers various options for checking differences in implementation, identifying missing implementations, and spotting extensions. I'd love to engage with the community to discuss its potential use and gather feedback on any aspects I might have overlooked. Could someone guide me to the most appropriate channel for this discussion? Thank you!
Shut up and get out! 👉🏻

Desk of Ladyada - Two Terrific Trinkeys + Z80 Processors https://youtu.be/fglUueXSCxU
Two Trinkey prototypes: the TRRS Trinkey for easy AT projects and the Pixel Trinkey driving up to 10,000 pixels. Also, Zilog’s Z80 processors hit End-of-Life, but are still available for a final purchase.

I have to wonder, how massive is miss ada's desk
its like the tardis
dinna shoot the messenger!
maybe more like a black-hole -- gobs and gobs of stuff goes in and you never know what ends up getting spit out via the poles
That sounds like something the developers might be interested in. Sounds like it could be used to highlight current differences that might want to be improved or implementations that need to be tweaked. Sounds like an interesting project. Recommend you post that in #circuitpython-dev
why can i not swear?
Profanity isn't allowed. See #code-of-conduct
oh
repost from #circuitpython-dev
You cant
I'm interested in learning the "right" way to write cpp for arduino, ie .cpp/.h
if anybody has good resources to learn how to do this, please post them :)
a lot depends on the definition of “right way”! also, you’re more likely to get help in #help-with-arduino
👍
Hey if anyone is there, does anyone know how I can do GPIO or other BUS protocols from my new Windows 11 Intel NVIDIA desktop, I see Lady Ada working with a windows machine a few years ago, but I don't know how to hook up electronics up to it for prototyping
@median viper FT232H or MCP2221A would be one way: https://www.adafruit.com/search?q=General+Purpose+USB+to+GPIO
or use a connected microcontroller (USB, BLE, or wifi in some cases), where the software and hardware prototyping happens on the microcontroller (but is accessible from the PC)
Oak tree root got into an irrigation pipe then grew around it and constricted it. This caused the well pump to eventually overheat since the water couldn't go anywhere. The water starts to boil inside the pump, melting internal wiring. The water inside the entire pipe starts to boils which deforms the schedule 40 pvc. Temperature of the water was probably about 180F-250F when this happens. This is just one section of the pipe, the total pipe is about 50 feet long. :/ I'm going to be digging for the next couple of days. If irrigation is on city water it's not a problem the sprinkler heads just wont pop up. For a well pump setup it'll burn up the pump and boil all your pipes. :/ This is why burying irrigation pipes deeply is a bad idea if you have a well pump.
digging is fun!
playing in the dirt is fun. add electricity and water and digging can get spicy. 🙂
yeah a pickaxe doesn't sound that fun. do what you gotta do. jackhammers come in handy too.
pic is easier than the jackhammer on this stuff
anyhow. its basically ready now
i need 4 deck blocks, and a 4x4 pressure treated post
i mean outside the door
couple reasons. the concrete on the main shed was a ton of work, and cost a lot.
this is true
i have lots of spare wood and the neighbour is giving me scraps from their new deck
i have steel for the walls. but none for the floor
the shed is all steel including the floor
roof i could do steel, but its easier to insulate with wood 2x4s
what's the horizontal wood piece for?
?
will that be a windows or just plywood to mount things to?
a flip top table? that's flipping amazing.
i like it, neat idea.
will come in handy as a table to set things on as you're building the rest. that's a really cool idea.
there are 2 rules, and one need. the need is that this be warm and sealed for winter use (this is the kitchen). the rules are it is legally a "porch" and as such cant be heated or fully sealed up/insulated
so i need creative ideas. that flip table is one. it is an "open" porch and that table just happens to cover the hole
if it's for a winter condition then yeah i'd try to keep it sealed. that flip table would be a pain to keep sealed in winter even with some type of large gasket.
yeah the window is smaller now, with the bar permanent. the opening will be a screen, and i will make a dpuble pane glass greenhouse box to sit on the bar and "seal" it up. and i get a little spot to grow herbs in winter
bar is 20" deep. greenhouse can be 10-12"
needs to be light enough to lift and move
make sure it's not longer than the roof drip line 😉
ha
roof overhang is....... 26"
from left. door, fridge, sink, laundry, stove, dishwasher. and the circle is a propane tank for the stove and water heater. (im restricted to 30A power)
i have 1 issue. the fridge door will hit the entry foor handle.
doh
hehe
i spotted that immediately
and was thinking it might be good to swap the fridge and heater
thats the only spot the fridge fits
but it's doable
just can't open the door and fridge at the same time and who really needs to do that often anyway.
no. i mean if you open the fridge, it will hit the door handle
cause that sticks out 2.5"
i was looking for low profile and flush handles
or sliding doors
etc
(door cant open out for snow reasons)
how are you going to prevent frozen water lines to the house? is that a concern?
water line is laid on the rock, so yeah, they would freeze so i need a water line heater
and insulation wrapping
are you thinking of solar to augment some of your power needs?
waterline heaters are really cheap now
big tree coveres the shed, so not worth while
though i have no idea what the sun is like in your area. i have no shortage of it where i'm at and i also never have to worry about freezing conditions.
yeah solar is not viable in this case. (it is on my main house)
well i gotta get to digging the sun is getting low and i have hours of digging ahead. thanks for showing your plans and progress. looking forward to hearing more in the future.
It should be an antenna.. 😅
ah
Aw yeah thats what i need for my heltec v3
That's what I got it for. 😄
If it's any good, I'll order another.
I need one of them thar analyser gizmos to test the antennas though.
loses patience while mother take literal 25 minutes to type in her email on a form
That's so cool, I'm getting the heltec v3 for 863-870mhz based on ur experience, would that make sense for a node
These folks just released a developer marketplace - really cool https://x.com/kodjima33/status/1782492783762399700?s=46
I wish Adafruit had smth simillar
are there non toxic spray paints?
the meme if you want https://www.thingiverse.com/thing:5923686
I work in the tech industry and this meme/comic, much like everyone else, has become a visual representation of the chaos we are subjected to on the daily. I had sought out to make something special for my coworkers and decided I would make my own take on this piece. Here are the details of the changes I made as I wanted it to more closely resem...
I hate that you have to work so much just to get by day to day in this world. I have so many ideas come to me while im working but I can’t do anything about them till the end of the day 😩
having just retired, i can tell you that jotting that stuff down in journals or notebooks means all that good stuff will be right there for you when you do have time (I wish i had!)
It’s cataloged, I just need to get off work at 4:30 and do it 😏
But thats.. checks clock 7.5 hrs away
it took me 30 years to learn patience, which made the last 10 years ok 😀
I have patience, probably too much.. because it often turns into procrastination
well, that too...
I need a bigger antenna
You don't always need bigger, when better will do the job. 😅
I'm planning to stick it up there. 😁
hope you have lightning protection -- that's a "Hit me!" sign if i've ever seen one 😱
You know people rejecting modern philosophy might use enlightening rods to protect their homes
does anyone know of a good online source for getting a custom transparent acrylic project enclosure built? I'm working on a midi controller and I don't really have time to learn a CAD program to design my own.
You could probably use fiverr or some other free lance app to hire someone to design it. You can then use companies like TAP who might allow you to upload custom shapes to me cut
There is also this kind of aluminum rail stuff: https://www.adafruit.com/category/228. Then you can add plastic panels
it comes in larger than 20x20 also
Good to know about the rails, I was kind of imagining just a completely clear box though
