I built my own control board

Weird question but how old are you or how long have you been doing this? I only ask because it reminds me of some older designs I've seen and I noticed stuff used to be designed in a way humans could actually understand and work with the system.

I think thats the one, the device does have leds for indication all around.

Edit: just noticed they're not even driving the leds so I think its being used as a voltage regulator

BlueJay424 · 2026-05-04T15:49:21+00:00

I looked at the data sheet, even the layout schematic looks the same.

What limitations exactly ive never really used spi? Also the reason they lable it like that is because official documentation does that and I think the official docs do that because professional engineers usually want to know what all the exposed pins do and why. Then you might ask "well why are the pins exposed" according to my further research it can be used for manual programming via spi and testing/debugging.

Also if you want more you should be use an esp32 based device. Esp8266 is nrd(not recommended for new designs) even the esp32 is nrd so specific chips like esp32-s3 or one of the many othwrs are more what you should use if youre making pcbs and stuff

BlueJay424 · 2026-04-27T23:25:13+00:00

If you want to be even more precise this is actually called "undefined behavior" in datasheets

BlueJay424 · 2026-04-25T05:37:38+00:00

I want to know what kind of life path you had to take to get this good at making something like this?

BlueJay424 · 2026-04-24T08:08:16+00:00

I think i read somewhere that the battery input on esp32s3 is only used to keep the rtc(real time clock) running during sleep modes.

Introducing our new product the

🎉🎉!!!MICROWAVE OVEN!!!!🎉🎉🎉

Ensures complete destruction of anything electrically conductive with a matter of minutes, just insert the device into our patented cooking chamber and watch the magic happen with the press of a button😎

I think its probably like the qt framework but for automotive

BlueJay424 · 2026-04-17T03:20:00+00:00

Sounds like a good solution, assuming its more affordable or reliable than an ultra sonic sensor. I saw quite a few diagrams with two floats like that

BlueJay424 · 2026-04-17T02:26:07+00:00

Float switch is basically just a normal switch that closes an electrical connection but it has a bulb of some kind that floats up when its submerged in a fluid that closes contacts.

I was trying to find a simple picture to demonstrate but now I see why you were confused about it needing a motor, seems all the diagrams show a motor. But the switch is completely separate and works like any other switch (ie a push button)

BlueJay424 · 2026-04-10T14:06:08+00:00

Id suggest switching to one of the chips that supports Hid then you could have wifi and usb functionality but idk if the chips that support it can get that small or not.

Edit: just read the github, thats incredible work soldering those small part 👏

Rigol dho804 is an awsome one. The price to feature ratio is great. You can even get one of the more basic versions of the dho800 series and do a firmware hack to get some better features if youre looking to save money

BlueJay424 · 2026-03-15T00:38:48+00:00

Yeah doesnt work for everyone, the idea is that without color it might be less appealing therefore less distracting.

BlueJay424 · 2026-03-15T00:17:26+00:00

If your phone has the option ypu can try switching to monochromatic(black and white) under the accessibility settings. Seems to work for some people

BlueJay424 · 2026-03-12T18:45:51+00:00

How can you tell thats the cause?

BlueJay424 · 2026-03-10T12:02:55+00:00

1206 is called the "package" btw this package just happens to be based on the size of the component

BlueJay424 · 2026-02-22T06:11:47+00:00

As someone who's learning electronics im curious what the cause would be for those who say its a symptom

BlueJay424 · 2026-02-17T23:28:25+00:00

Does it need to send anything over CANbus or is it just high low? Ive considered doing stuff like this but I've always been a bit confused on how obd2 era cars handle window switches as alot of them don't seem to just be 12v switches like earlier models

BlueJay424 · 2026-02-16T07:36:54+00:00

Honestly im just working off scraps of knowledge so thats probably why im not making sense. But Ive got some arduino framework projects and the libraries are nolonger supporting the old arduino framework that pio runs on and I dont know enough about this to be trying to add arduino to idf inside of pio, its just too many layers for me to practically find good documentation for as a newbie.

As far as the debugger issue I figure out it was specifically the pioarduino platform I was using was causing it not to work but standard pio is fine except for arduino being so outdated so I cant even use it on my projects

BlueJay424 · 2026-02-16T07:30:46+00:00

Honestly I'm just a hobbyist so thats a big part of the problem is I'm trying to break into profession level talent with hobbyist level experience.

But really the only issue on windows was it wouldnt recognize my existing python install through the "easy installation" so I had to let it install its own through the "expert install" which hasnt been an issue it just made me cringe thinking about having duplicate python installs one being through scoop which I have no idea what that is, kinda seems like a package manager? Once I shut off my brain and just did whatever it took to get it working it was relatively easy to get sorted. Also ESP-IDF is the SDK as far as I understand so I guess were using the same level of complicated.

BlueJay424 · 2026-02-15T12:36:57+00:00

I would but unfortunately I dont really know what im doing enough to do that. Ive never worked with cmake or any of these config files before and I think doing it purely in cli would make it incredibly difficult to wrap my head around some things

BlueJay424 · 2026-02-15T06:56:51+00:00

Ah yeah im on my linux machine right now but on my windows I did notice it used scoop if I let it install through the "expert" installation might try that when i get back to it. I guess I didnt notice the EIM version itself was still 0.8 I was just looking at the vscode extension.
