The PICsynth is an interesting new synth DIY project for a real analog synthesizer, using easy to get components and capable of a wide range of sounds.
- Dual oscillator mono synth
- Really easy to build using just 1 custom programmed PIC chip, 4 ICs and single 12v supply
- All circuits built on veroboard – no printed circuit board making skills needed
- PIC based dual oscillator and digital keyboard scan
- Analog VCF/VCA/Envelope
- Waveforms : sawtooth, square (with pulse width adjust), triangle
- Tuning presets : in-sync, out-sync, detune1 and detune2
- Expandable, first two modules shown below.
Here’s a samlpe of the PICsynth sound:
More demos are available at the PICsynth site.
The PICsynth looks like an easy project. If there’s a circuit board designer out there, though, that’s up for creating a board for this, it could develop into a super-easy starter synth project that still has room for hacking.
Cost Estimate in USD
- PIC chip $15 including postage and packing from NZ
- PIC board components $8
- Waveshape board components $24
- VCF/VCA/Env components $24
- Misc $18
- TOTAL $89
- + cost of keyboard (mine cost me $10)
- + cost of wood for case.
- Around $21 is the cost of the 7 potentiometers – if you can find a cheap source of these or use salvaged ones you will save a lot.
You an find the details here.
If you build a PICsynth, let me know what you think about it in the comments.
