This is probably a really stupid question, but why is there holes in the pork barrel board where no components go? Am I supposed to jump wires between these? My board isnt working and I think this might be why... I did the jumps for the IC though.
Hi there, could you post few close pictures of your board? maybe i could help :)
I don't have a camera on me right now, but I am talking about the holes under like R10 and C6. I think there is 5 of these total (excluding the ones for the BBD jumpers)
Those holes are used just to connect top and bottom layers, so don't worry about that.
Are you shure that you have connect right pads for BBD chip? do you have any signal passing thru
No signal whatsoever :( I'm thinking its some sort of short in the circuit. The onlny chip I might not have orientated correctly is the 4558 because it has no divit in it, only a circle, which way should that be orientated?
Also, the terminal voltage drops down to around 1 volt when plugged in, what is this a sign of?
4558 could be a problem, circle is usually placed near pin number 1... so you should put that side up.
and if you have voltage drop then there is for sure some kind of short in circuit..
Sometimes you have what's called vias and that just takes signal to the other side of the board.Check all your soldering and wiring.
Post some pics of both sides when you can. It will really help us help you.
