I am tackling a ton of new things with this project and it is glorious.
Currently, I am working on the electronics for a brass collator. (It sorts brass for reloading ammunition.) It integrates a IR break sensor for counting shells, detects motor jams via a now integrated INA219 and has a ton of logic coded in the Arduino Nano for detecting various errors.
The plan is to actually integrate the Atmel MCU on the new board to make the whole thing smaller, eventually.
For now, I am learning how to isolate the MCU from the rest of the electronics so it doesn’t get fried by short circuits or other kinds of current spikes. This thing eventually has to withstand average shop conditions and abuse. (I am still learning about ESD protection; There are two open spots on the board for TVS Diodes, which are on order.)
It’s over regulated and over decoupled currently, I think. There is a ton more to learn, so I will keep the revisions going!
Cheers!
Side note: Soldering SMD components without a solder mask is a pain and it looks like garbage. I have been researching how to apply a mask with the equipment that I currently own.
Now that my CNC router is dialed in, I am probably going to coat the board in paint or “real” UV hardened mask and etch it off with the CNC… I dunno yet.
