TABOR DIY workshop
This workshop is open to everyone, including beginners, and will allow you to build and take home a complete, fully functional Eurorack module.
What is TABOR
TABØR is a chaotic analog rhythm source based on four avalanche transistors. Its operation relies on a quantum phenomenon: the reverse avalanche effect.
How it works
A capacitor is charged through a resistor; once it reaches a critical threshold, the transistor enters avalanche breakdown and begins to exhibit negative resistance (the more current flows through it, the less resistance it opposes). The capacitor rapidly discharges, and the cycle starts again. This process generates chaotic and unpredictable oscillations, further enhanced by cross-FM modulation between the four oscillators.
What we’ll do
The workshop will begin with a brief theoretical introduction to avalanche oscillators and the principle of negative resistance. We’ll then move on to the practical part: the assembly requires soldering only a few through-hole components (Eurorack power header, potentiometers, and jacks). Most of the smaller components are already surface-mounted. We’ll finish by testing the module to ensure everything is working correctly.
