instrumentation and contact or whatever. (Milwaukee, WI)
As my modular synth experiments started getting more complex, I felt that I was losing sight of one of my founding principles--in short, "Keep it simple, Stupid!". By limiting an entire electronic instrument to what could be crammed into the space inside a hollowed-out Gideon Bible, it ensured that the result would be extremely primitive--no room for knobs on pots, wires and components in plain view.

I was hesitant for a long time to build these commercially, as many of the designs were my take on already available circuits, and because I simply didn't have enough free time to work on anything besides my own stuff. For a long time, though, I've wanted to do a Dan of Earth release which was basically a still-playable anti-record/art object--something you could JAM on, or just switch on and listen to (sort of like a Noise "Buddha Machine"). Now I think I've got it figured out.

I present to you, the "Gideon XOR"--two random voltage generators (each w/ independent Sample/Hold rate, slew, and scaling controls) feeding two pulse VCOs (each with adjustable pulse width). The resulting waveforms are ring modulated together (technically, a logical operation called an "Exclusive OR" is performed on the two waveforms (Hence the name!). For "square" waves, this sounds pretty much like ring modulation). This edition was created as a set of 20.

I will be selling these at the Milwaukee Noise Fest (Sept 17-19, 2015). If you will not be able to attend, get ahold of me via the usual channels (colbecklabs (at) gmail.com) and we'll see what we can do. To hear recordings using the Gideon XOR model Bibletron or see videos of Bibletrons in use, see below.

A brief owners manual/cheat sheet is here.

Oh Good Grief--Bibletrons are on the face book! <---look here for all the latest news about Bibletrons in general, and the Gideon XOR in particular!

live action!

Gideon XOR schematic
======================
Here's the schematic of the Gideon XOR, if anybody wants to horse around with it. Nothing too esoteric here. The random voltage circuit, at the top of the image, is adapted from the Moog Rogue. The original Moog circuit (also Oberheim OB-X, probably tons of others) used the infamous MM5837 digital noise generator chip to generate the white noise that the "random voltage" is derived from. My adaptation uses a PIC12F675 which has been programmed as an almost pin-for-pin clone of the 5837--more reliable, non-repeating noise, and probably won't set your bench on fire! You can either get one of these Noise chips from Electric Druid, or buy a PIC12F675 from Mouser and program it yourself (program also available from Electric Druid!)

Here's a good interview about Bibletrons...through clever editing, I actually sound pretty smart and reasonable! "Noise Without Borders" is a cool noise zine with a wide variety of interviews.
