The Drum Buddy is an amazing analog synth drum machine vintage, check out the photos and video! -

…a one of a kind light activated analog synthesizer / rhythm machine hand crafted by New Orleans musician and inventor Quintron. The basic principal of operation is that there are cadmium sulfide light sensors hidden inside the colored tubes around the rotating black can and as the light holes pass them by, the various oscillator sounds are charged, filtered, bleeped and blooped in a variety of different ways. Each of the 4 oscillators is represented by a different color and each has been designed to complete a total rhythm kit, much the same way that the different elements of an acoustic trap set go together. The Blue pipe is the “kick drum”, the red is the “snare drum”, and the green is the “organ oscillator”. This green oscillator is raw VCO melodic organ tone controlled by “general” and “fine” tuning knobs for playing songs in a whole new way – no chromatic scales on this instrument. The yellow is the “space” or “scratch” oscillator which is plain un-effected, eerie sine wave tone which increases and decreases directly depending on the amount of light that is shed upon it. There is a 10 turn / 10K potentiometer wired to control the spinning can motor speed.
