Noise567
I have been building a couple of these ultra simple Noise567′s here and there, what a great little circuit! Super noisy, accepts an input, and has the craziest distorted ring modulator/fuzz depending on pot position. The only drawback so far has been that it has a constant VCO running that you play over. It’s fine when dealing in drum machines and keyboards that you want to sound like hell, but it just doesn’t cut it for guitar in my opinion. I tried a couple of different cap and resistor to ground combos in different places with some luck, but it always seemed to mute out the real beauty of this circuit. Anyhow, I’ll keep soldering away and searching the forums for some relief from the ultra VCO. In the mean time here is the orig schematic for the Noise567.
I’ll record a video in the next couple days, hopefully I’ll solve the crazy VCO issue before that. Happy building friends.
UPDATE:01.30.12
If I could get the constant osc. to shut up, this would be the best effect ever. There are a couple different versions of the 567 (the LMC567, LM567, & LM567CN that I know of so far) available, all with different audio results. I hear the LMC567 does not work in the NOISE567 circuit, but I am using the LM567CN. I’ll have to order all the different varieties and give them a go.
Opto-Oscillator LFO based on the 40106 IC
Super simple OPTO LFO for a friend who was looking to design his own enclosure based around some kind of electronic noise toy. Here is an even simpler drawing of the schematic. (I mistakenly called the glass insulator I used to diffuse the light and inductor, too many beers before filming).
Circuit Bent Yamaha DD-5
Circuit Bent Yamaha DD-5 with a 10 position rotary switch providing various distortions and glitch beat variations, plus 4 more buttons providing additional variations and distortions.

The Revenger!
I made this out of stuff from my junk box/pile. The main circuit is from a Radio Shack desktop toy called “The Revenger”, complete with Laser, Machine Gun, & Bomb sound effects. I may have to record another video using the Dub Box Delay so you can hear the true LoFi reggae glory. Simple pitch bend on the timing resistor also attached to touch points, one other touch point going to a leg of the capacitor.
Finished another couple of Power Starve Pedals
I like to call them power sag pedals but from what I have been hearing and now reading the correct term is Power Starve or Voltage Starve.. Dying Battery Simulator is still acceptable. Anywho.. 2 more have been built and shipped off to Hollywood where they will no doubt become the star of the pedal board they inhabit and power source the inhibit.
Get your own! These are built to order so case color and knob may vary.

8×8 Seqencer front panel done
This is a project I started a few months back for friend who is looking to sequence 8 Korg Monotron’s for live performance… once the Monotron Delay’s get delivered I will most likely follow the great advice, directions and tips at Steve Woodward’s site, he has compiled most of what is around on Monotron hacking and has a great comment thread going on.
The sequencers are based on the Baby 10 design. I used a pair 40106 ic’s for the 8 LFO’s instead of the more common 555 timer. The the 40106 runs very quietly while the 555 clicks at every step (check out this video of my Baby 8 and you can hear the 555 click). I based the LFO design off of the info over at Beavis Audio Research.
Cleaning a filthy Roland TR-606
Just opened this up to give it a good cleaning, looked like someone puked on top of it and it seeped inside. All better now.
To clean this bad boy I sprayed it with a mix of Simple Green and water (25-75), scrubbed it with a nylon paint brush and sprayed it down with clean cold water. Immediately after this I sprayed the entire board down multiple times with compressed air. At this point I would still wait 24 hours to power the Roland up.
Next time I’ll try to remember to get a shot of the board all soapy.
