Chaos Drone Looper, modification from Chaos Looper.
As part of the public program of The Instrument Builders Project in Melbourne Australia, I conducted a workshop on DIY electronic synthesizer making. The workshop was using Squaresynth module and I gave it along with Benjamin Kolaitis and Lintang Raditya. The workshop is hosted by MediaLab Melbourne. Photo documentation bellow.
Based on CD4093 and CD 4094, 8-bit synth using shift register plays a crazy tunes. Schematic, PCB, Board Layout and Eagle Cad files bellow.
Squaresynth is a module of a costumized simple synthesizer based on quad oscillator on my earlier post here. It uses the same chip, 4093 and modified it as a touch/moist sensor. I developed Squaresynth for workshop purpose, to invite the participants learning the basic electronics through introductions of electronics logis such as oscillator, introduction in reading schematics, and also introduction on electronic components. The demo showed how it sound above. Documentation, schematic, PCB design bellow.
An analog synthesizer I made using the Noise Looper circuit from SGMK (http://www.mechatronicart.ch/). I built two of this synth with different cans of Dji Sam Soe special editions. The circuit is using PT2399, a digital delay chip which you could get from the local electronic store in your city. Many information about PT2399 can be found here. Video, documentations and instructions are bellow.
