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, 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):

  1. stop writing page titles like “DIY” if you ain`t gonna give any instruction or schematics or so… instead put something like “DIM”(Did It Myself) if you`re not willing to give your knowledge away and just wanna show off…

    pretty awesome anyways

  2. hey, what do you want to know??? should I post instructions on these things? I don´t get a lot of response, so I thought this might not be interesting to alot of people… anyway, if you need some schematics or stuff let me know! you could also write me an email burow (at) gmx (dot) ch


  3. hi,

    very cool thing!

    I’m very interested in documentation/schematics/code/parts/whatever i need to rebuild as you mentioned in your comment above 🙂

    you should get my email address from the comment.

    thanks and greets :walter
