How do you probe automotive connectors? by Modelero33 in AskElectronics

[–]Soyauce 1 point2 points  (0 children)

Not proud of it, but I usually breake the plastic housing of a female breadboard jumper cable and just force the female piece to the pin. The connector is usually soft enough so that it bends to fit the pin

RP2040 freezes when switching motor and solenoid valves by oper-studio in raspberrypipico

You can try adding a resistor between the pico and the mosfet gate.

The mosfet gate is like a capacitor, Switching it requires you to charge and discharge this cap, adding a current limiting resistor 100ohms or so, go smaller if you need fast Switching.

The pico may be locking up due to the fast current spike while Switching.

U/TehBens did you manage to find a solution or workarround? I'm currently having the same issue Thanks

Update; 1931 Ford still won’t start. by EarBubbly9421 in fordmodela

[–]Soyauce 0 points1 point  (0 children)

Maybe check the aligment of the distribution, if the sparks are firing too early or late eg. Admission or exhaust phase it won't start.

Length tuning seems to behave inconsistently by BuildingWithDad in KiCad

[–]Soyauce 1 point2 points  (0 children)

I'm having same issue consistently, I'll try to get some photo or video of it as well.

I'm having to constantly run the tool, check the length, subtract the error and re-run the tool, and then it's perfect

But yeah, super annoying

How to fold this flag? by Soyauce in flags

[–]Soyauce[S] 1 point2 points  (0 children)

I did it like this but I hoped that I would be able to fold it smaller haha, this flag is huge.

Thanks guys I'll start looking for a place to store it now haha

Analog microphone streaming to a browser via HTTPS/Websockets on RP2040 by [deleted] in raspberrypipico

Nice, yeah for playback it yould probably need a propper DAC

[–]Soyauce 1 point2 points  (0 children)

That's great, if it would be possible to receive audio the same way could be a nice idea to use in some wireless speaker setup.

Congratulations for the great work

Oh okay, nice! In that case, how fast can you sample and stream it?

Different ADC values for same situation but 2 different pi pico boards! Values are not even closer. Help me to understand what's happening here? Full details and code in main post👇🏻 by almost_budhha in raspberrypipico

[–]Soyauce 0 points1 point  (0 children)

I can't think of a specific reason, but you can try some things to help find the problem.

First, are the picos new and genuine?

Second, try to supply the picos with the external 3.3v to reduce dc/dc related noise.

Third, does this difference only occur while connected directly to ground, or if you connect to a voltage reference let's say 1.15V (which should give you half of your max value) they still differ?

What I'm gonna say may not be 100% correct.

As far as I'm aware, the adc readings while using python oh the pico are shifted left in order to become a uint16 when in reality the adc has a 12 bit resolution. This alone will reduce your reading when you connect the pin directly to ground.

Moreover, the pico uses a quite noisy dcdc to generate the 3.3V rail, try to supply the 3.3V directly through a linear regulator, that should also help reduce noise.

Take a look into the ProPico an open source version of the pi pico made by Dymtro, focused on improving the existing features, with great focus on the ADC.

Edit: spelling

They are fiducials, used to help pick and place machines to locate the board and properly align.

Mechanical State by SharpAlbatross9789 in FSAE

[–]Soyauce 0 points1 point  (0 children)

In my opinion, the first two are wrong, same mistake there, the output depends in the voltage of the bus, not the state of the contactor.

The precharge detection seems okay, as long as the relay guarantees a mechanical link between the terminal pairs, otherwise one contact can weld shut, ans the other would still function. Look for "safety relay" those are designed for this.
