quad true random voltage generator

The transistorkreis random is a quad true random voltage generator for modulation and for digital noise. There are two inputs to trigger new random voltages and each of the four outputs can be switched to

  • uniform or normal random distribution,
  • unipolar or bipolar voltage range,
  • an amplitude of 5 Vpp or 10 Vpp.

Assembling the DIY kit for the Eurorack format is straightforward since all SMD components are already soldered. Nevertheless, basic knowledge of soldering and electronics is mandatory. The generic design of the transistorkreis random supports any modular format and its firmware is open source. Respectively, you can customize it to suit your requirements. Including screws and washers for your module carrier and a Eurorack power cable with the Eurorack version, which is skiff-friendly. Please watch this demo video on what it can do and have a look at the manual for details:
