◊ Printed Circuit Boards
Participants in the Electronoize Playshops built wonderful CMOS-based noise devices (sometimes called "Lunettas") on wireless breadboards, and needed a way to move their completed designs to something more robust for gigging. The Looney Board provides a flexible platform to do just that. As an open platform, it can be used to build a all sorts of CMOS-based sound devices.
We also sell PCBs based on early Buchla synthesizer modules. Long out of production, original 100 series modules fetch collector's prices; these PCBs allow folks to experiment with these obsolete circuits
All PCBs are provided on an as-is basis for personal use only. Only PCBs are supplied; additional parts and assembly are required. These are minimally supported projects meant for experienced DIYers; you need to be able to read schematics, source parts, stuff and solder the boards, wire off-board components, troubleshoot, and figure out the mechanical aspects such as front panels and housing.
PCBs are $15.00@; ppd in the US, additional $10.00 postage/handling (per order) outside the US. Use the Paypal "Add to Cart" buttons to purchase. Make sure your shipping address is included in the paypal transaction.
You can also download some FPD front panel designs (for Frac format synth modules); or, buy Fluxmonkey recordings...
LooneyBoard 1An open-ended platform for implementing your own CMOS noise-making designs. Preconfigured to support 40106 chip (6 square-wave oscillators), 4093 (4 gated square-wave oscillators), 4011 ("ring modulator"), 386 amplifier, and a couple of passive mixers.

194 Bandpass Filter [Restocked 3/2016]All discrete transistor bandpass filter (not voltage controlled), based on the Buchla 194 circuit. One audio input, 4 filtered outputs: LP <200hz, BP 200-900hz, BP 900hz-4khz, and HP > 4khz. In conjunction w/ a 4-channel mixer, can be used as a comb filter or graphic EQ.

◊ Free (as in beer): Frac format Front Panel designs
For gearheads: a collection of downloadable front panel designs for SDIY. These are in FPD format, and laid out for Frac format synths (easily modified for Euro). CHECK THE DIMENSIONS BEFORE ORDERING, particularly hole sizes for pots and PCB mounting.
