The diagram in question is this one:

That to me looks like ground to the top, middle left alone, bottom gets the out. In that wiring however I got nothing.

Once I switched the bottom “out” wire to the middle everything sprang to life and everything works peachy now.

Interestingly enough I was actually able to find someone else who had the same issue and had blogged about it. Sean over at Bearly Sounds had the same issue with his WSG construction.

When I first powered on the unit nothing happened. I decided to test for voltage first. First I checked the battery. I know it sounds stupid but how many times have you had something not work only to find out the batteries were dead? Then I basically traced the voltage. Everything looked good. As it turned out, I soldered a wire to the wrong post on the 1/4″ jack. Once I corrected that problem the WSG immediately started making weird sounds! Woo hoo!

As always, I am concerned that my aggressive debugging of the last 3 hours might have screwed something up, but everything seems in shape.

The WSG is now sat in a whole cut in a cardboard box, ready for oak case construction after the Christmas break

EDIT: See the next post, this issue is now fixed.

Finished my weird sound generator kit over the weekend, and it was one of those soul crushing moments in electronics where you finish the meticulous soldering and excitedly plug it in and it makes no sound at all.

I had a quick poke around and was actually able to make it make a sound, but I’m somewhat at a lose as to the reason.

If I short point A on the switch, to B the ground (I put all my ground down onto the plug since it was bigger than the location on the pot in this diagram. Anyway, when grounded, it makes weird sounds, but the left “Oddness Filter” doesn’t do anything and it seems like most of the pots in Voice A don’t work. So clearly I’m just by passing something.

I reheated all the points in pcb and no difference. I need to double check all my capacitors are the right way round, and my resistors are in the correct places. Beyond that I’m at a lose. I’ll take some pictures of the boards in case someone can see any obvious issues.
