"Based off of the schematic for the 'toy organ' I have built this handmade electronic musical instrument, called 'The Wench'.

It has a series of 8 buttons, which are not in any particular musical scale. There is a photocell to the right of these buttons that can control the overall pitch when selected. You can also switch to the low frequency oscillator for siren like effects.

There is a "starve" knob that controls how much voltage the circuit is getting. For "normal" operation, have this knob turned all the way up. When you turn it down it changes the character of the sounds dramatically. Use it in conjunction with the LFO, even if the LFO is not switched on, for interesting effects.

There are 2 body contacts to the left of the buttons. These effect the pitch of the notes when you touch them both at the same time.

The Wench has a built in speaker, and a 1/4" mono output jack so you can process it's sounds or plug it into your amp, mixer, etc.

Runs on 1 9v battery.

Housed inside a sturdy cigar box with rubber feet added to the underside for grip.

A great toy for experimental musicians, as it lends itself more to "noise" rather than "music". Use the power starve, light sensor, body contacts and LFO to get crazy sounds from sputtering sqeaking and bleeps to screams, lasers, squeals and video game sounds. The built in speaker is very loud and the ultraviolet leds will pulsate with the sounds!"
