For what it's worth, I don't particularly like it. It's kind of abusing the [ ] syntax for a "parse this general command query" behavior, which also takes an unpredictable number of additional parameters of different data types. I'd generally expect to see something which is more Pythonic, with function calls and keyword arguments, etc.

@olive dome if you don't mind me asking, how are you prototyping with the USB FIFO mode of the 2232H? Is there a premade pmod/breakout/whatever one can buy, or have you built a custom PCB?

olive dome Sep 1, 2023, 3:44 AM

#

I just go with custom PCB

#

Adafruit also has a FT2232H breakout too, if you don't mind a bunch of wires

raw jasper Sep 1, 2023, 3:45 AM

raw jasper Sep 1, 2023, 3:46 AM

#

I thought the breakouts only "broke out" the UART functionality, like how it's done with most FPGA devboards.. thx for the pointer!

ebon dew Sep 1, 2023, 8:05 AM

#

Technically an Arduino Uno is just a breakout board for the ATMEL chip, and feathers are just breakouts for whatever chip they have on it.

#

A breakout is typically a way to get chip logic to a format that will work with a breadboard or other type of GPIO that you can interface with.

#

I don't know if that's a standard definition of it but that's how I think of breakout boards. From a logic chip to an IO. For example you can't really wire to a BGA but if you put a BGA chip on a board with traces to IO holes then they become more accessible. Yes you can actually wire BGA chips it's possible for the sake of argument no normal sane person will attempt to wire directly to a bga.

late fulcrum Sep 1, 2023, 12:50 PM

#

The Uno has two other features: a USB interface and a bootloader, which enable programming it without an additional programmer. That, along with the portable IDE and basic Wiring functionality (setup and loop), lower the barriers to entry that just a microcontroller on a board present.

I got object detection working at full fps by downscaling and I can tell if the box for detection contains the x,y of the aim point 🎯 I'm wondering how many types of object detection I could do before I slow down the fps and if I could downscale more and still have it work 🤔

glacial wigeon Sep 1, 2023, 4:03 PM

#

oh, that gives me an idea on how to improve perf more

#

downscale, and use a basic "where is the face" ai

#

then crop out just that region, the image now has far less data, and run a second "who is this" ai

edgy apex Sep 1, 2023, 4:12 PM

#

Yes you could scale the coordinates from the downscaled detected face to crop the full res face for recognizing who it is

patent hemlock Sep 1, 2023, 4:57 PM

#

not a bad notion at all

edgy apex Sep 1, 2023, 7:17 PM

#

I figured out how to do that so I can save full res face. it kept getting mad at me about
BufferError: cannot close exported pointers exist
so i just ended up making a copy of it
face_crop = m.array[y:y+h, x:x+w].copy()

if you use it as an analog input it can sense anywhere from 0v to 3.3v which will output in print or echo as a value between 0 to 65535. (pin.value * 3.3) / 65536 to get 0-3.3v value

edgy juniper Okay I see this but don't fully understand. It says very little power flows into...

I think the distinction between "fault tolerant input" and not fault tolerant refers to the fact that on some pins (afaik the ADC pins, the not "fault tolerant" ones), a current flows if a voltage is applied to the input pin, but the voltage of the RP2040 is zero (because it's shut down)

#

(It says that somewhere in the rp2040 datasheet, please double check)

I bought a homemade 1/5 scale rock crawler chassis off of eBay for a project. That said, the plastic bits including the suspension seem to be stock. What I want to put on it turned out to be too heavy, I have a little experience in this area, can I just get stiffer Springs? If so to get the right size can I just measure the outer diameter of the spring and the length and possibly the compression distance under a known Force?

#

I know that Springs are not really linear, but what can you do?

I was just wondering do all STEMMA QT breakout boards include pullup resistors for the SCL/SDA pins?

#

And also if I understand correctly can STEMMA QT boards always accept 3-5v logic? So, for example I can plug any STEMMA QT sensor, display, etc into an Arduino Uno with 5v logic level without potentially damaging it even of the sensor or whatever on the board is 3.3v?

ebon dew Sep 4, 2023, 9:53 AM

#

tender heron I was just wondering do all STEMMA QT breakout boards include pullup resistors f...

to my knowledge yes if they are I2C they must have the pull up resistors on the module.

#

the logic level depends, no, it is not always 5v compliant for a stemma qt module. some are 5v compliant but not all. it's very important to read the documentation on the stemma qt module you're using it with to ensure if it's 3.3v and/or 5v compliant. if you attempt to use 5v logic on a stemma module designed only for 3.3v logic then it would be possible to damage the module. adafruit has logic level shifter modules specifically designed for those types of scenarios. it adds another module and layer of complexity to a project but it is necessary in those situations.

tender heron Sep 4, 2023, 10:26 AM

#

I see, thanks for clarifying that.

#

@ebon dew stemma qt to stemma qt is always compatible though right?

#

Like there's no 5v only stemma qt or only 3.3v stemma qt that is incompatible with each other?

ebon dew Sep 4, 2023, 10:36 AM

#

That’s an excellent question. Im not sure.

tender heron Sep 4, 2023, 10:43 AM

#

To my understanding stemma qt is qwiic compatible. And with qwiic also to my knowledge only being 3.3v I'm assuming stemma qt is 3.3v by default and for those that are 5v tolerant do a logic level shift from 5v to 3.3v. But not 100% sure.

UART is probably the easiest way with RX/TX if you want board to board communication.

ebon dew Sep 4, 2023, 4:00 PM

#

feather to feather or 3.3v logic to another 3.3v logic board is probably easier than needing an intermediary logic level shifter.

ebon dew Sep 4, 2023, 4:05 PM

possibly but not by adafruit to my knowledge. a featherwing logic level shifter does sound very convenient but it would be up to the PCB designer as to exactly which pins are used with it.

rapid geode Sep 4, 2023, 4:06 PM

#

yeah, i see that it would be case by case for the exact pins you need

ebon dew Sep 4, 2023, 4:09 PM

#

and there would be the inevitable danger of stacking another featherwing on top of that and zapping it with 5V. it's a dangerous proposition which is why it likely doesn't exist as a featherwing. :/

Ah, that's a bipolar, unidirectional logic signal. In most cases, you don't even need a level shifter for that. Most 5V logic will accept a 3.3V input as a logic "high"

glacial wigeon but you need a spec sheet to know what voltage/current/frequency are best/safe

You don't really need a spec sheet, you can work out the inductance and saturation current (or use a controller that does it for you), and derive the drive parameters from that. However, to find the max voltage, you'll probably need a few sacrificial units.

sick apex whats an actual usecase for a thermoelectric cooler

They're handy when you want spot cooling/heating, especially reversible, in small space, with no moving parts. You can stack them for even more cooling. They're not particularly efficient, and they do have a limit how cold they can go, but they're compact, quiet, and easy to use. I'm toying with the notion of putting one in a phone case along with a small fan and heatsink, to keep my phone from overheating on hot days. However I fully realize I'll probably be wearing a battery pack to power the whole thing.

#

any ideas?

late fulcrum Sep 5, 2023, 8:07 PM

Do you need RGB? 3mm bi-color LEDs are easy to find. And you can get all sorts of tiny surface mount. But if you're looking for through-hole RGB LEDs, it's hard to fit four leads in that package, so you get things like https://www.aliexpress.us/item/2251832580507733.html

Write up a contract with migration, support, and maintenance. It doesn't matter how far into past support you are with it.

ebon dew Write up a contract with migration, support, and maintenance. It doesn't matter ...

The boss doesn't want to, because he has been too much of a pain even for him

if client doesn't want to agree to terms then client can find someone else. value your time appropriately. if they do not agree to your value that is not your fault.

Sadly, Boss Level ejits don't always see it like that.

Thankfully, my role is pretty well-defined... so I have a lot more leeway to refuse tasks. 🙂

then send a nicely worded email that you're currently too busy with other projects to work their migration into your schedule.

dusty citrus Sep 6, 2023, 11:59 AM

What I found most weird since I've been working here
Is that people could get directly to the source but they don't
Like in place of using like random hosting service they got to the current company who works as a middleman for those services bahh

If I were still in the webhosting game, I wouldn't mind... but I left that WAY behind.
Kinda wish I hadn't, because my current role is utter tedium.

there's nothing wrong with outsourcing as long as the outsourcing can do a competent job up to your migration standards.

rapid geode Sep 6, 2023, 5:11 PM

#

i jsut outsourced a pizza

#

ok. so now the question. do i make my keyboard case from a block of aluminium. Or do i buy a block of black ABS for $55 which is way easier. OR, do i use wood, cause... why not?

#

haha

raw jasper Sep 6, 2023, 5:15 PM

#

I mean, it would be very much in character if you built it out of wood xD

burnt tendon Sep 6, 2023, 5:16 PM

#

Yeah using ABS would be against the grain.

ebon dew Sep 6, 2023, 5:17 PM

#

wooden keys with a wooden enclosure sounds more appealing. a nice stain and it basically can become an heirloom keyboard.

raw jasper Sep 6, 2023, 5:17 PM

#

"heirloom keyboard" is a new one. Hat's off to you

rapid geode Sep 6, 2023, 5:27 PM

#

well it will be hand wired. maybe it will be valuable in 3000 years

#

but yeah, ideally it would be corian keys and some sort of PC-CF housing. like if it was a real industrial use product.

#

but its not. its just in my house haha

burnt tendon Sep 6, 2023, 5:28 PM

#

I mean, part of my motivation for my current keyboard project is that I'm fairly happy with the one I've got but I can't get any of them anymore.

rapid geode Sep 6, 2023, 5:29 PM

#

my worry with wood is the "plate" will be too weak.

burnt tendon Sep 6, 2023, 5:30 PM

I forget if layup epoxy would be better

rapid geode Sep 6, 2023, 5:31 PM

Mind sharing some details? I'm curious

burnt tendon Sep 6, 2023, 5:32 PM

#

Oh yah, so I've got a numeric keypad that was the "test piece"

#

And the goal would be to make something that's roughly shaped like a MS Natural or Natural Elite keyboard, except minus the numeric keypad, with readily available keycaps.

#

And fully split instead of split but connected.

raw jasper Sep 6, 2023, 5:33 PM

#

ooh yeah, MS natural isn't a thing anymore

#

I had one in the past

burnt tendon Sep 6, 2023, 5:33 PM

#

I had a blob of them and I'm down to my last one.

raw jasper Sep 6, 2023, 5:33 PM

#

:(

#

Are you going to use mechanical key switches?

#

MS's used rubber dome

#

IIRC

#

But, at least the normal profile "typewriter-like" mech keys, ruin the ergonomics for me tbh

burnt tendon Sep 6, 2023, 5:35 PM

#

Yeah, like, I'm unambugiously not a mechanical keyboard person but it seems like the mechanical key switches are the best option.

#

Obv finding the right keyswitch type.

rapid geode Sep 6, 2023, 5:35 PM

#

they are easiest for sure. just pick one that feels closest to a dome i guess

raw jasper Sep 6, 2023, 5:35 PM

#

I think there are some that have a flat profile

rapid geode Sep 6, 2023, 5:36 PM

#

red is linear, no "click". thats what i have right now.

raw jasper Sep 6, 2023, 5:36 PM

rapid geode Sep 6, 2023, 5:36 PM

i sorta dont care about keyboards all that much. im much more fussy with mice. and the best mice are long gone. thats a project! scan my mouseman 96 and print a new body and use some sort of modern diy friendly laser innards.

raw jasper Sep 6, 2023, 5:38 PM

Oh gunky ball mice definitely weren't fun

rapid geode Sep 6, 2023, 5:38 PM

this wasnt a ball. it was led.

but mostly it was about the feel. all the new mice are ambidexterous and too small or these horrible deformed gaming blobs.

Guess it's time to abandon mice and switch to keyboard-only navigation :P

rapid geode Sep 6, 2023, 5:41 PM

#

the cnc panel is keyboard plus touch screen. it works well for that application because the functions are limited

#

hmm. $85 for black garolite (paper). $59 for black ABS. $147 for delrin. $125 for POM (kinda the same as delrin but weaker). $300 for glass filled polycarbonate. oh dear.

#

thats my plastics choices

#

aluminium is "free"

#

for wood i only have mahogany big enough. ha. that would be amazing and stupid all at once.

rapid geode Sep 6, 2023, 6:06 PM

Besides, the whole point of git is its capability to be distributed... This does not really apply to issues/documentation on proprietary git hosts (such as gh issues), though..

rapid geode Sep 6, 2023, 9:41 PM

#

alrighty, time to actually make things. ABS plate. added some mounting screw holes and such. sized it to fit a 1/4" abs sheet i have.

late fulcrum Sep 6, 2023, 9:41 PM

#

Laser cutting, milling, photolithography, or something else? Given the countersinking, I'm guessing milling.

rapid geode Sep 6, 2023, 9:46 PM

#

milling of course.

#

its a fully 3d carve so thats the only way to make it

#

well besides injection moulding

#

if i made them to sell id probably just get an FR4 plate done by a service. but this is a one off
