ok the start of the project was a keyboard witch i would control the vco and have a sample and hold ... i wanted to make a mobile synth with the added option modular synthesizer.

first thing i did was take the diode matrix circuit off and redesign some new pcb which resistors for the control votage and had to add 98 keyboard switches.
All boards made using press n peel system.

PCB board


PCB board with resistors had to make 3 boards they were not the same
took a lot of working out so the keys would line up ..

here with some boards installed and some of the keys installed










ok all the boards for phaze 1 of the modular synthesizer

Ok the easy bit for me was making the case i have 2 mates that are welders and one is a panel beater so he did some work for me i sat down and had the a coffee and design the case in my head lol i have no brain i'm retarded must be thinking i guess your rigt as my skill level in a electronics is low but i am driven to get this done also have another friend who was well into electronics so i have help when i need it..

here the case



was sprayed with commercial paint for vans so hard




Power supplys have dual 15+ and 15- and dual 12+ and 12- also 9V+ single output ..
