Updates on Tellun.com

via Scott on the Modular Panels list:"I spent the day updating a number of projects on my website. Most of these are for my MUUB based utility modules. In some cases I simply added a Bridechamber panel to an already built module. For others I completely rebuilt the module using MUUB-3 boards in order to avoid stacking PCBs on top of each other. In some instances I created my own panels by making


Analogue computer - Lorenz Attractor

POKEY sound chip experiments

YouTube via hotchk155. Anyone else remember that tune?"The Atari POKEY was the classic soundchip in the Atari 8-bit home computers and many 1980's arcade games. This clip shows some of my experiments in driving a POKEY from MIDI. A PIC receives MIDI data and two 74HC595 shift registers are used to assemble the 12 lines of bus data for the POKEY so it can be driven from a humble 14 pin PIC16F688.

DIY FPGA 8 Operator 16 Voice FM Synth

via JovianPyx on this electro-music.com thread. Full details here. Note this is in the making."The path labeled "Operator 0 Feedback" is a connection for feedback of operator zero into it's own input. It is used as an envelope controlled waveshaper. This feature is disabled by setting the feedback LEV and feedback BIAS controls to zero.The path labeled "Operator Modulation" is the connection





Arduino Based Voltage Controlled Grunge Pedal

"I've talked about doing this forever, so I am happy to finally be able to introduce my 95% complete, voltage controlled DOD Grunge FX-69! Frac-rack modular synths have been in my opinion missing a voltage controlled distortion module, with wave-folders being about as close as I could find. I had a torqued FX69 sitting around, and figured it would sound wonderfullyterrible in my synth setup."

YouTube via denha (click and scroll for more). Synth drum. "LFO OUT, OSC OUT, CV IN, was added."





Repairing silicon rubber membrane contacts; Installation instructions

YouTube via sounddoctorin"Bob Weigel of http://www.sounddoctorin.com documents his contact repair invention. A material created for NASA is backed with 3M adhesive and cut into disks the size of typical Panasonic, Fatar, Roland and casio contacts (or close enough to work :-). ) Other companies have offered paint which often doesn't work and then you have a bunch of paint with a rough surface





Fender Starmaster Organ Part 1

YouTube via sounddoctorin"Bob Weigel ( http://www.sounddoctorin.com ) endures a cold and shows a bit around the insides of one of the rarest organs on earth. Well certainly the rarest of the really cool ones I think :-). Porto built the machine for Fender and they apparently decided to abort production immediately with only 9 of them released I've heard.
