Pretty basic question but I am struggling to find the words to get the correct search result. The soldering iron I bought came with very narrow tips that I think are supposed to be used for circuit boards and components....
With soldering you want to maximize heat transfer at all times so flat surfaces (chisel tip for example) are usually ideal. If you want to remove solder from a hole in a PCB you’re better off with a round tip as that has the most contact area then. It will make it easier to use a solder sucker in that case for example. Personally I have the chisel tip on 90% of the time and might be willing to switch to the large flat one.
Well. That would be the overpriced commercial version. I'm not a fan of Tesla because of their anti repair practices and I'd rather build my own anyway. The learning experience alone makes it worth it.
Indeed. Batteries require a BMS that can handle this amount of cells as well and they're quite obscure. In a smaller battery pack I've built every individual cell has a current fuse as well as a thermal fuse that pops at 60 deg C.
Seems your linked website as a very believable conclusion attached to it. I have a similar issue where the relay module would behave erratically. In my case it was when the relay module/595 chips received power before the Arduino was fully powered up. It’s unlikely that a load affects your relay module as they should never be connected to the main circuit.
I guess something like a pulldown resistor on the SER, CLK and RCLK pins would solve the issue since that would kill any noise. The noise is probably the kind of voltage that BARELY registers as HIGH but highly random.
That or making the relay module only turn on after the microcontroller has finished starting up using a mosfet or something.
I want to connect five OV2640 cameras via FPC to an ESP32 on a custom PCB. Is this generally possible and does the ESP32 have enough power for this or do I need an ESP32 for each camera? The frames per second are not so important as the cameras will be used as QR code scanners. Which components allow to run so many cameras with...
What tip should I be using to solder wires together?

What software do you use for PCB design?
I’m interested in learning how to make a proper PCB rather than perf board with wires all over the place.

First of all, I apologize for the lack of a “formal” schematic… I tried to draw one out, but got buried in the nuances of it :)...
