November.2015: THE GRISTLEIZER- Design/Build.

In the 70's, Chris Carter, of Throbbing Gristle, built a few of these Gristleizer Effects Processor's for the band. His circuit design was a modified version of the original design by Engineer Roy Gwinn. The Gristleizer was never commercialy produced and with Throbbing Gristle's place in Music history as pioneers of Industrial Music being established, The Gristleizer itself became quite legandery. Hence, when in 2009, Endangered Audio Research [EAR], authorized by Throbbing Gristle, re-produced the circuit design and made printed circuit boards for sale, I obtained one from EAR, sourced the necessary parts and built a Gristleizer, using a Dr.Who lunch box that I had, as the enclosure. Hence, The Dr. Who Gristleizer........ Glad to finally add The Gristleizer to my collection of Effects Processors.

February.2013: The Nova Drone Sound & Light Synthesizer: Sequencing patterns for Mixed Meter Applications in Dance.

Using the Nova Drone Sound and Light Synthesizer in live Music & Dance interactions where Complex Human Movement structures (Choreography) call for mixed meter applications, there is need for quick access to fixed rhythmic structures from the Nova Drone Synthesizer. Utilizing the Raspberry Pi and Scratch software for programming sequences, interfaced through the GPIO on the Raspberry Pi, a Relay and the Prototyping Board on the Nova Drone, allows for building of presets, further extensive explorations and control of the oscillators and filters of the Nova Drone Sound and Light Synthesizer. - Manjunan Gnanaratnam


The Nova Drone Sound and Light Synthesizer: Designed and built by Peter Edwards of Casper Electronics.

The Raspberry Pi and additional components: Adafruit Industries: Raspberry Pi, Starter Pack, Pi Dish, Volt Meters, USB Wireless adopter, Jumper wires, LED's


Software: Scratch- Install Scratch version from Cymplecy (includes Python Scratch handlers)

Communications: ZyXEL Portable USB powerd wireless router- For PWLAN [Performance Wirless Local Area Network] communications between all Components/Instruments/Computers through RDP, VNC, SSH, OSC & UDP during live performance.

May.2012: SHIFT @ NORTHERN SPARK. Choreographer Vanessa Voskuil. Design/Build of Sonic & Sensory Environment
