Here are various projects I've built over the years. Many were completed. Some where not.
A half watt, battery powered guitar amp with vol/gain/tone controls. Based on the LM386 chip, a fun and simple project that yields a usable practice amp.
Take five fuzz circuits and put them all in one enclosure with various mods. The first real Beavis build!
Frank Zappa's Digital Delay
Wherein I have the honor to fix a dead rack delay from the Utility Muffin Research Kitchen.
Four Knob Rat (FKR)
Four Knob Rat distortion pedal with switchable clippers and lube. Using the Ruetz mod, and LEDs, MOSFETs and standard diodes for clipping.
Arduino Punk Console
A microprocessor controlled tone sequencer using the wicked cool Arduino Board. Includes schematics and source code.
Concept of idea to simulate rotating speaker effect. I wonder if this would actually work?
Double Rat Rack
PRoco once put two Rat distortion pedals in a single rack-mount case and called it the R2DU. In this project, we mod an R2DU to make it a double-FKR, or, an eight-knob Rat.
A fuzz with 10 knobs, sort of the junior version of the original fuzzlab. Schematics and notes included.
Large Hadron Delay Collider
Re-housing a Malekko E600 delay and mating it to a homebrew Powerglove for real-time controllability.
A redesign of the Noisy Cricket Half-Watt amp, this time with a 12AU7 tube preamp stage and a modified tone control.
A 12AU7 tube-based boost/overdrive running off a 9 volt battery, designed by Matsumin. A super simple build. Build a nice tube preamp without dying from high-voltage mistakes!
Watch me build a completely impractical 2x12 cab out of wood trash cans and various bits of hardware detritus from my garage.
The Big Ass Throbbing Grinder: one of my very first builds--the Dr. Boogey distortion pedal. A stupidly-oversized
enclosure, problems with scale on PCB etching, and innappropriate wire gauge choices make this one of my worst builds ever!
Turn standard pedal boards into something more usable and fun.
Modular whack box with a load of patchable effects. Never finished, but some interesting schematics came out of it.
Digital Sequenced Wah Filter
AKA the Precision Ass Tornado. Using an arduino microprocessor to generate variable LFO signals which feed a variable low-pass filter.
Build your own Noisy Cricket practice amplifier with 100% Radio Shack Parts! A fun project except Radio Shack bit the bullet, went tits up, into the great beyond, etc. So no more Radio Shack parts.
The world's loudest guitar pedal? Two LM386 power amp chips in series in a distortion pedal...Named after Nigel "It goes to 11!" Tufnel.
Frequency Analyzer Rehouse
A true-bypass rehouse of one my favorite pedals ever, with CV In mods. The Electro-harmonix Frequency Analyzer is probably the best analog ring modulator pedal ever, with massive 48v DC headroom and tone for years.
1/2 Watt Class A Amplifier
My build of Tim Escobedo's whimsical power amp, complete with simulated LED backlighting.
Big complex guitar synt effect from Music From Outer Space. Never got it to work.
Various Misc Builds
Assorted projects which don't particularly warrant an entire page and writeup.
Motors and Gears
Adapt a vibrating pager motor into a hillbilly device. Complete with video that reveals the super secret Beavis Design Methodology!
Various Misc Builds
Runoffgroove.com's great little amp, the inspiration for the noisy cricket, and a fun project.
Single transistor low gain overdrive--super easy build. My version uses vintage soviet transistors.
One box, one tube screamer, all the mods. Several folks have built their own take on this, loads of fun.
Eliminate hum from crappy power supplies with this easy to build beginner project.
Build a passive stutter pedal. One of the easiest builds in the world.
