DSC_0168These two always seemed like a pair to me

Probably one of the weirder things I’ve built. This is a 12″ Celestion Modern Lead 70 Speaker and a 386 IC amplifier in a 12″ tom drum shell.

I got the speaker for almost nothing, because it had been kicked inI got the speaker for almost nothing, because it had been kicked in

When I built this, neon green duct tape was on sale. A lot of stuff I built had neon green duct tape all over it.

All of the circuitry and the battery are contained inside the drum shellAll of the circuitry and the battery are contained inside the drum shell

The circuit is pretty simple; only 1 IC, a few resistors and capacitors, 3 knobs, and a pair of switches. Oh, and a 9V battery and an input jack. Under $20 in components from your local electronics store!
