First off, i'm not a total electronics noob, etc.
I was following the instructions to build the stimulator / relay / main board.
I completed the stim and the relay board with no problems, so I went on to tackle the main board.
Everything was going good till I got to step 23 where you check the cpu socket for 5v, etc.
I don't get voltage anywhere on the cpu socket, the grounds test good against the stim ground, but I just can't get voltage from ping 1, 19, or 32.
Went back and checked all the connections, polarity, etc and everything seems perfect.
PS, the board is getting power on some of the parts, such as D11, etc.
Problem could lie in the stim, but I can't find much info on testing the stim.
TIA. Just looking for a place to start.
Stuck on Step 23

Re: Stuck on Step 23
Not getting any voltage on U5 also, not sure what to check.

Got it, forgot D10 somehow!
