A clear plastic storage box with black latches, lying on a cream bedspread. On its lid sit five paper circuits, four cut as hearts in the corners and a rectangle in the middle labeled Paper Mosquito, with a strip labeled Paper Power Rail above it. Small pots, toggles and jacks poke through the lid, wires loop between them, and a speaker shows through the plastic.

Five of my paper circuits in a clear plastic storage box: the Paper Mosquito, Dragonfly, Opto Duet, Ring Mod and Hornet, all running into one speaker in the base. It sounds horrendous, and if you really want to aggravate your neighbors, boy have I got a box for you. It is a big box, too: about a foot and a half square.

What it does

These are the hearts from my paper guides, built and wired into a tub for a synth meetup: the Paper Mosquito, the Dragonfly, the Opto Duet, the Ring Mod and the Hornet. A paper power rail runs them all off one DC jack, and a paper bus wires the other four straight into the Hornet, with no level controls, and the Hornet drives the speaker in the base.

It sounds horrendous. There is no volume control and no mixer, the speaker makes noise even when nothing is turned on, and it is ugly as sin. But if you really want to aggravate your neighbors, boy have I got a box for you.

Every circuit in it has a free guide on this site, if you would rather make your own mess.

Controls

The knobs and toggles: Each circuit has its own, on the lid, the same ones its guide gives it. None of them is a volume control.
Power: One DC jack feeds a paper power rail, which feeds all five hearts. A standard pedal power supply runs it.

Circuit: my own paper circuits, free on this site. Built, painted, and finished by Onion Madder as an original one-off - not affiliated with, endorsed by, or a clone of any commercial brand.
