"Here is a totally unique old school circuit bent noise generator/synth. I picked up this mystery box recently and do not know any details as to its origin. My guess is it is early 70's home/custom built. The circuit board is hand wired bread board and it was done by someone who knew what they were doing. The sound is somewhere between a sound Aphex Twin might use or The 60's group Silver Apples. The tone can range from a drum machine like hi hat sound to bleeps with noise added in varying degrees. The tone frequency can vary the pitch and sounds like a pretty cool resonate filter. The emphasis puts the tone on a continous 4/4 to 4/2 4/3 4/1. Pretty simple overall but absolutely loads of fun to tweek in real time. The design is interesting in that it was built into a japanese wood box and works like a traditional music box, ie when you open the lid the unit is turned on. This is a self contained unit with a built in speaker. There are currently no provision for an output jack but that would be easy to do wired off the 2 leads from the speaker. I could not see what chips were used in the design as they are not visible without taking the unit apart. The unit runs on a hard wired 9v wall adapter. Maybe someone out there knows the origin of this vintage piece? Perhaps it was built for a specific music experimentor back in the day or just as a hobby project I do not know. At any rate this a cool conversation piece and a complete one off synth. Way kooler than a speak and spell! The unit measures 8.5 x 5 x 3.5 inches."
