What did we do at dBm 2025

deadBatterymusic 2025 was a great little festival where we indulged in the CMOS chip and very low voltage and more.

What did we do at dBm 2025

dBm 2025 program

Construction of the test hardware based on ideas and circuits from Uwe Schüler and Ralf Schreiber based on Starvation Synth and Chaosz. Detailed information via KulturgüterSchuppen.

our dBm research system consists of these modules :

  • Power supply : USB powered, LiPo battery, 5V out
  • Power starving controller :  voltage and current control with  potentiometers & CV  inputs
  • CMOS oscillator (D.U.T.) : various topologies of Schmitt-Trigger based squarewave oscillators
  • High impedance buffer & amplifiers: line and feedback outputs Potentiometers for gain and feedback
  • C-multiplier:  electronically variable capacitance with potentiometer and CV control. Acts as capacitive load for D.U.T.
  • triple CV out pseudo random pattern generator : for controlling CVs of power staving controller and C-multipliers
  • vactrol module : DIY dual vactrol  with exponential CV control for potentiometer replacement in D.U.T.

On Sunday there was a musical morning pint (Frühschoppen) with some of the participants!
