The connections are simple now.
It got a little wiry but it plays alright.. The following sample is a single note (until the end where I start to improvise The loop is made by the envelope only (decay time)

The switch multiplexer.. lots of diodesand cables
midi interface (a little deviation from schematics here since I didn’t have a P900 or 4N25 optocoupler at hand and used a 6N138/9) The (typical) power supply. 5v with 7805
This is the Digital to analog converter. It uses lots of 1% resistors. The schematic mentioned that for the most significant parts, 0.1% resistors should be used but I didn’t use such. It really has no effect on sound (at least for me that I didn’t expect anything special).Again, a little attention to the schematic, [...]
I decided to make JAREK ZIEMBICKI’s AVRSYN. But there were only the schematics and no board layout so I had to make my own. So I started laying it out on eagle but I got on a deadlock due to the fact that I didn’t want to make a double sided board. I would etch [...]
This is an octal RGB clock. I made it so it can be impossible to actually tell the time but nevertheless its beautiful (in its own way).
There is an atmel AtMega8 µCU and 6 RGB leds. Two for hours, two for minutes and two for seconds.Each led can be Red, Green, Blue, or a combination [...]
Not exactly synth-DIY but this is a timer I made for my soon-to-post PCB oven. You just set the time and keeps track of it, switching it off when it must and securing it from accidentaly opening the lid, saving my eyes from UV burn
