Steampunk Synth
This represents my latest work, a Steam Punk Synth. I spent a lot of time in the layout and design of this unique instrument. What once was an old Westinghouse Volt meter now is the enclosure for a square wave based analog synthesizer.
Accented with brass fasteners and hand crafted control knobs.
Complete with 1/4" audio output jack, volume control, input jack (7-9VDC), ON/OFF switch and three controls for Frequency, Rate and Choke.
Additional video soon to be added.

PSS-270 Video
Here is the video of the Yamaha PSS-270:
Presented on this keyboard are the best (from what I found) of the available --circuit bent--modifications. The FM Data line modification interrupts the data between the FM chip (YM2413) and the XC194AO chip. By cutting off and selecting different Voices, altered sounds, tones and drones can be generated. It also works on the Rhythm section. The LFO mod was the last bend found during my search of the circuit board. By using various some caps I can alter the tone and range of tone with the control (potentiometer). The LED's' light up once this data is transfered from one part of the corcuit back in to the XC194AO chip. This mod is the Top left knob and switch (with RED and YELLOW LED's).
I'll post additional information on the FM modification later. I get questions often regarding this; it works on many YAMAHA series and not that difficult.

Circuit Bent Yamaha PSS-270
I just finished this Yamaha PSS-270 keyboard.
This build includes the FM data line modification via 8 switches, distortion glitch--one switch, 2 data scrambler channels (with LED indicators)--switch and knob controls, filter--switch and knob controls, 2-stage drone/LFO modification--switch and knob controls.
