This is a kit to build your own Screaming Angels.

It consists of a kit electronics parts, materials, clear plastic box. I will send a link to download the instructions for use once purchase has been made.

You will need the following tools to build the screaming angels 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 its box:

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

Here are details of what the complete item can do:

Screaming Angels is a 6 voice stereo optical theremin.

It produces 6 triangle waves at similar but generally unrelated pitches so produces atonal sounds. The pitch of each triangle waves is controlled by its own light detector. These 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
