DIY Build Instructions – KOSMODROM CHAOS DIVIDER [v 1.4 PCB SET]
First of, thank you for your purchase of the Tsyklon Labs KOSMODROM CHAOS DIVIDER DIY Kit [details below]. If you are a DIY Synth
Veteran [or, as we like to say at Tsyklon Labs - "Hero of Synthesizer DIY"], then this kit will be a fun build. If you are a DIY Synth Novice, you
have selected a build that will certainly strengthen your skills – but, follow the directions and take your time with this build. It is not
exceptionally complicated, but there are a lot of steps. During the build, you will put together many types of circuits – power, digital logic,
analog signal manipulation, high voltage DC [160V], and cold cathode tubes. If you are into coding, you'll even have the option of creating
your own alternate frmware for the Chaos Divider HV. Also, if you are not familiar with component naming, please check out page 37.
First, let's make sure that you have everything on hand before we heat up the iron. The tools you will need are as follows:
- Soldering Iron [if you have both a fne point and a chisel point, that will work well] and Solder
- Wire Cutters
- Needle Nose Pliers
