Noise Box is based on the gating properties of the 4066 Quad Switch and is amplified with an LM324 Quad op-amp to produce some truly horrifying noise. “Sound” would be too pretty a word to call the sonic mess this device creates. The project runs off of two sets of 9 volt batteries.[more]

This is a simple MIDI keyboard designed for use with standard PC soundcard with MIDI/Game connector. Keyboard is powered directly from Game port an there is no need of power supply unit, and no high voltage risk. If you need to use it as standard MIDI device, you should build (or buy) a proper power supply and opto-isolated MIDI output buffer. You could find more information about such buffer module on[more]

Many beginning DIYers choose a one-transistor boost or distortion (like the Electra) as a first project. The Tweak-O is this kind of pedal, but it offers adjustable clipping, better sound and more control than many such circuits. The construction methods shown here are much the same as those used in many commercial and boutique pedals. If you build the Tweak-O, you will have learned enough to tackle a more complicated pedal, and maybe even enough to modify the Tweak-O to taste.[more]

The work is comprised of a 4 x 4 gird of 16 “drinking bird” toys. This toy is an example of a thermodynamic heat engine, converting heat energy into kinetic energy. The blue fluid inside the toy is methylene chloride, a chemical with a very low boiling point. When the head of the toy bird is saturated with water, the playback cycle begins. As the water evaporates, the head cools and the methylene chloride vapors inside it condense. This creates a pressure differential between the head and the body which forces fluid up through the body into the head. Once enough fluid has passed into the head, the center of gravity shifts and the toy tilts, taking up more water from the glass and allowing the internal fluid to flow back down into the body. The cycle then repeats.[more]
