"This is a handmade Rockit synthesizer designed by Hackme Electronics and built from their circuit board. It is a monophonic digital-analogue hybrid using two 8 bit VCO's through a digitally controlled analogue filter and VCA (with 2 LFO's thrown in for good measure). All parameters are directly controllable on panel (and via midi cc). It is powered by 6 x AA batteries (rechargeables are fine). It weighs 1.8kg.

Rather than use the standard Rockit case, I have housed the synth in a wooden box with brass front panel. All controls are securely attached to the panel rather than PCB mounted. Leaded solder was used throughout.
The controls are:
Back row
Drone switch, volume, on/off, midi-in, midi-thru, audio-in (to use filter and VCA), audio-out
Left block of controls (from back to front)
VCO1 waveform, VCO2 waveform, VCO mix, VCO2 pitch
A, D, S, R for VCA
Filter cutoff, filter resonance, filter ADSR depth, low/band/high pass filter selector
A, D, S, R for filter
Right block of controls
LFO routing matrix
LFO waveform, LFO rate, LFO amount, LFO sync
And at bottom are the patch save/recall controls..."
