PRIMAL - Hyperchaos

PCBs - USD18
Panels - USD20

Hyperchaos circuit based on a paper by C Li, et al. It can be built to run at different speeds simply by installing different capacitors. Very easy build, no special components needed.
There are 5 different CV outputs and 1 gate output. The CV IN is associated with the CLIMAX pot which determines how high the peaks go. The module can be greatly influenced by the CV in signal and can exhibit some fairly nutty responses at times.

ARSEq - 10HP eurorack version

Panel = USD22
PCB set = USD23

Build guide & BOM

Panel template

The ARSEq ( = Attack Release SEquencer) is, as the name implies, a hybrid sequencer and AR envelope generator. It contains a counter circuit with reset, 4 envelope generators and a mixer/inverter stage to get the sequenced output. The envelopes can be inverted if desired to give a greater voltage and complexity range of the output sequence. The individual 4 envelopes are available on the panel as well.
The main difference with this circuit and a regular EG is each envelope requires 2 clock pulses, one to start the attack and the next to start the release stage.
Yes the pots on the panel are a bit tight at 10HP, I should have made it wider, maybe I will one day?
