Small box for single speaker
by mkellner, published
A small box for a single speaker with a hole for a volume control on the side.
Print, snap in a speaker connect a volume control and amplifier (many available for cheap on ebay) and go.
I originally made this to try to make corn-starch monsters -- you can see the residue in the pictures, but I think my simple 555 based square wave tone generator wont do the trick. I'll try it with a small amp and sine wave produced from my phone or computer.
