At some point I was obsessed by the wish to build an analogue synthesizer. Excessive googling lead me to this Website:
Great site with lots of HQ schematics, board layouts, etc.
So, for some reason I found myself buying parts for the “Sound Lab Mini”. Being based in Germany, I bought most parts from http://www.musikding.de/ (pots, knobs, JFETS, …) and http://www.reichelt.de (resistors, opamps, caps, PCB raw material …). The MFOS website features a very fine board layout which can be transferred to an “Europlatine” (standardized PCB raw material measuring 16cm x 10 cm) via the direct toner method (http://thomaspfeifer.net/direct_toner_pcb.htm). A nice thing about the direct toner method is: you can also use it to craft beautiful front panels or print component labels on the no-copper side!
It was a very lengthy and tiresome build … but thanks to tidy handiwork (or plain luck) the synth wobbled perfectly, once completed.
Yeah, not that much creative and original work from my side … except: I modified the front panel to fit the aluminium housing that I intended the synth to reside in. If you are interested, here it is:
Here are some pics taken during the build:
