This is a kit to build your own Warring Demons.

It consists of a kit of parts and a CD-R full of detailed instructions and photos which will show you how to build the noise maker step by step.

You will need the following tools to build the Warring Demons circuit:

A fine tipped soldering iron, some solder, side cutters and wire strippers. A helping hands type device will help you keep the circuit from moving around. Also a wide tipped soldering iron is useful for getting rid of any solder bridges between track of strip board if your soldering is less than perfect.

You will need the following tools for mounting the circuit into it box:

A dot punch or sharp nail/screw, a 7mm drill bit, a 3mm drill bit, a battery powered drill, some plyers and a stanley knife.

Here are details of what the complete item can do:

Warring Demons is a 6 voice stereo optical theremin.

It produces 6 square waves at similar but generally unrelated pitches so produces atonal sounds. The pitch of each square wave is controlled by its own light detector. These modulate each other and are paired off into 3 waveforms in the left channel and 3 waveforms in the right.

It is powered by a single 9v battery (Not included). The switch on the side is a power switch. The output is via a 3.5 mm socket at line out level. Please note this is not a headphone socket, you will need something suitable to amplify the output e.g. a stereo with aux in, computer speakers, a soundcard input etc.

It measures 10cm x 8cm x 3.5cm
