Sreaming 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 comes with an instruction CDR which also contains a FREE set of build instructions.

It measures 10cm x 8cm x 3.5cm
