This circuit takes a continuously variable dc voltage and outputs only voltages related to each other musically, using the 1v/octave standard. It utilizes a preprogrammed PIC which is included with purchase of a PCB. It is has a very low parts count, requires no calibration, and is small enough to be used either as a seperate synth module or as a daughter board to be attached to the input of an oscillator or output of a sequencer/s&h/other cv generator. For schematic, bill of materials and theory of operation for newer boards, download this PDF file. If you have a rev 2.0 board, here is the old documentation on that.
I decided to post a few things that I have learned this year. All wire is definitely directional. What I did was rewire my amp again, but not with expensive teflon wire or solid silver etc… All I did was reverse the direction! The clarity was amazing.
Building and applying a Vactrol Building and applying a Vactrol 28.06.2010 20:21:37 Today at RuinWesen we bring you another technical blog. This time, we will be discussing the construction and applications of a Vactrol.
Bio Engineer and musician Noah Vawter is best known for inventing Ambient Addition , the 1-bit groovebox , PSPKick and combyop synthesis . In each of these musical instruments, he combines math and design ideas to illuminate the situation around music, encouraging the democratic notions of freedom and cooperation. He is currently a Ph. D. candidate studying with the Computing Culture Research Group at the MIT Media Lab in Cambridge, Massachusetts.
8/2/2010 - Michael and Noah share some research into acoustics which can increase the efficiency of selectively-chosen, yet reasonably-priced woofers. Yes, for those who love to get down and to the source, I can heartily recommend Keele's paper and especially On the Specification of Moving-Coil Drivers for Low-Frequency Horn-Loaded Loudspeakers, from W. Marshall Leach, Jr.
Tron is a simple 16 step, 8 part drum pattern programmer. It isn't as fully featured as others, nor as expensive. It's designed to be small, cheap and simple to use. It also sits well with GorF and Zira . I've long been wanting a drum pattern programmer to drive my Chameleon when it's running the fahrenheit soundskin to drive the TR-808 sounds.
Gorf is a simple 8 step sequencer. It isn't as clever or complex as the Sequentix P3 nor as expensive as certain other sequencers. I was bored one sunday, and wanted to build a simple sequencer I could use to test Defender and other synths I was building. I wanted something simple, small and that only used bits I had lying around, So Gorf was born. It uses one Atmel Mega32 micro, eight pots, ten switches, four 7-segment displays and a handful of other commonly available parts.
Anonymous asked: Any news about the project? Have you had the time to get back on it? Been trying to make a living with indie app development.
Monday 04.03.2006 6pm came home today to find the 9090 PCBs from Trevor came through my mail slot. 2 PCBs and 4 ICs. 9090 boards from trevor arrived I found some nice scans of the PCBs on c0nsumer's 9090 wiki . PCB scans Tuesday 05.09.2006
Hey, nice to hear that. Yes, there were some changes to the hardware and the project, we will post those when possible. It should work on the Uno board, I got a 2009 to test later this month just in case. One change I'm doing is add 2 extra C165 shifters and make the interface buttons use those extra pins instead. Right now the single analog input with multiple buttons doesn't work the way we want, and its not multi-press compatible, something that is nice for future updates.

x0xb0x worklog Tues 10.25.2005 6:30pm I happened to be home sick today.
I created this guide to mod my x0xb0x as shown above, it's mostly cut-n-paste from the x0xd0x wiki , with several annotations, parts lists, wiring diagrams, and other clarifications made by myself... Basically I did this so I could have a paper copy while I worked... Feel free to integrate any of this info back up to the x0xd0x wiki.
