hmmm lets see... an ESP32 requires an input signal to the ADC, preferably analog such as a sinewave or music etc. My computer has a sound card in it ...

Well its been quite a while and found my answer, the part that poofed was a diode and I replaced it with a 4007 and it lives... Loaded up the code and...

@davee what gave me the idea that it was a diode was the color, black, with a line printed on it as most diodes have and a code of SL. When the "item"...

salvage the relays off of the board. 99% of the time, A/C relays are DC relays with diodes in them to change the A/C to D/C. It all sounds feesible, j...

I would go for an external power supply, 6@50/50 is pressing the current a tad.

3D laser printing is a slow and tedious process, especially when you are doing it in a manufacturing enviroment.

@zoolandermicro I would go with the 6/2 switch. You can double up on the contacts per volt line to handle the amps and by having 6 position you can ...

@zoolandermicro Ive got about 5 of these in use, the 0-100 voltage is the supply power going into the meter from your supply, the 4-30 supplies power ...
