The idea behind this PCB is to show basic electronics and create a small low-fi, low price, synthesizer
a good price for the basic package with all parts should not be more then 5-7 EUR
maybe we should also think about basic "modular" capabilities with simple breadboard cables
- Atari Punk Console, based on 556 (NE556 ~0,12 EUR @ aliexpress)
- Chaos NAND, based on 4093 (CD4093BE ~0,08 EUR @ aliexpress)
- Baby10 Step Sequencer, based on CD4017B (CD4017B ~0,07 EUR @ aliexpress)
- Some basic Low-pass/High-pass Filter (RC Filter)
- Maybe some kind of Keyboard like input
- some kind of distortion
- The PCB (0,86 EUR @ http://dirtypcbs.com/)
- Cheap low quality potentiometers (~0.21 EUR @ aliexpress)
