Schematic and build instructions for the PhotonTricoder Workshop PCB (v1.0-1.2) Start with installing the three 100k mixing resistors. Then add the three 100 ohm current limiting resistors. Bend the legs of the six photocells to fit the footprint on the pcb. Install photocells. Add the two sockets for the ICs making sure to line up […]
TORTURE DEVICES are electro-acoustic instruments that are simultaneously sound generators, audio processors, and performance scores. A set of lights embedded in the instrument determine where, how, and when performers play. The sound is picked up by contact microphones and processed through shifting feedback delay lines. The result is an unpredictable choreography of movement, sound, and light […]
Stereo prototype version of the Voice of Saturn SpaceQuest lofi analog bit crusher/tremolo pedal. This uses a simple fet transistor based sample and hold circuit with a variable rate clock to go from a slow tremolo to audio rate modulation that results in a bit crushing effect.
The Booster Stage is a fet based circuit that allows for tons of extra gain and some killer harmonic distortion. Made custom to order.
Germanium Mosrite Fuzzrite inspired guitar pedal with limited edition artwork by Nathaniel Murphy.
The Voice of Saturn Synthesizer mk II was released in Spring of 2016 originally as a kit for a workshop for the Tom Tom Festival in Charlottesville, VA. There have been several revisions with the current one being configurable as a standalone device or a eurorack module. It features 4 oscillators, 2 lfos, a ring […]
The Voice of Saturn Modulator was a module designed around an OTA based Voltage Controlled amplifier and a function generator chip that served as an LFO. Also included was a simple attack release envelope rounding out the Modulator as a useful utility module.
The Voice of Saturn VCF is based around the CEM 3372 Signal Processor chip. At one point ca. 2006 I wound up with a decent sized amount of these discontinued chips and I decided to design a filter module around them. I also had a great source for joysticks and loved that sort of user […]
The Voice of Saturn Sequencer came soon after the VoS Synthesizer and was an expanded take on the Baby 10 sequencer utilizing a cd4017 decade counter at its core. I wanted something that could sequence my Realistic (Moog) MG1 amongst other things so it was important to add an S-Trig output as well as the […]
The Voice of Saturn Synthesizer was the first device I created that bears the Voice of Saturn name. It came out of my own experimentation with the venerable 555 timer IC and was the result of some circuit bending of some known schematic ideas, the basis of which being the Atari Punk Console. Schematic Manual […]
Custom modwheel midi controller with Arduino from Travis Thatcher on Vimeo. Using the Doepfer’s modwheel assembly and an Arduino I built this midi controller for a client that needed a standalone box with a center detented, spring loaded pitch bend control and a free moving volume control. There is a switch that puts the device […]
