Nice stuff Shaan if messier is better then you should check out this one there isn't a decent pic of the board, but you can see some of it

also this one Click the image to open in full size.

It was a trigger circuit for my car alarm. Basically had a couple of SCR's which would (I think) conduct if the ground was removed, causing the caps to charge and set off the current sensing alarm

These are the two I mentioned in the ugly prototype and amp threads

Here are a couple more, neither still in use.

The first one I think was a voltage probe (for car electrics).

The second one was a mixer that I made for doing a uni project where we had to make a radio play. We used it for mixing recorded voice and background music. One of the pots was scavenged for some other use at some point.

Default Another old amp

2006 Job. Recently brought back for replacement of two broken knobs...

Only the left most pot is used as the volume control... others for the gap filling.
