DIY LoFi-Synth with 8-Step Sequencer

Finally I have made some fotos and also a short video demonstration of the LoFi-synth I recently built with a group of very cool people, initiated by the Swiss Mechatronic Art Society www.mechatronicart.ch, and hosted by the Basel based group iPlugin

Basically the course was divided into three nights, the first in which we built the synthesizer, based on the IC CD40106, the second we extended this one with an amplifier based on the LM386, and the third part covered the assembly and modding of the 8-step-sequencer based on the ICs 4066 and 4022… I later extended these circuits a little bit, designed some filter and waveshaping mods, and packed it all together in two little breadboxes, soldered and hot-glued all together and voila: the DIY-Breadbox-Synth was born!

Big thanks especially to Marc Dusseiler and Markus Hasselbach from SGMK and Raphael Döring from iPlugin, you opened up a whole new dimension for me of making music, electronic and art match together… heavily inspired by the DIY-spirit I started on building the MB-808, which is the next big project I will be posting a lot around here;

check out the video here – some more, with a more musical focus will follow (at 1:10 its getting interesting):

Polysix Midi Retrofit Board installation

I did this one some weeks ago, and also documented it all, but did not have the time yet to post it all… so i might take the time this week…

UPDATE: Here are two shots I made during the installation. The main problem was the drilling of the hole to the outsinde, it took me almost 1 hour to do this, and as a result I damaged the drill completely! see the pics.

The Install itself is really easy, just solder 6 cables to the apropriate points, and mount the Midi jack. thats it! If anybody is interested in a complete report on this, i have pics for every step and some more explanations on it…
