Otter pyCCDgui

This software is based on the work of Esben Rossel. Please check this link. I added zum features to make working with the instrument easier.

  • Simple calibration to [nm]-scale by using cheap laserpointer
  • Simple make and store of calibration curves and measurements of concentrations
  • Simple system for recording the kinetics of reactions.


A pulse counter based on a ESP32 with a OLED display. It counts the nummer of pulses during a fixed time frame.
The idea was to build a small and cheap counter as an interface between a device witch genenerates 5V TTL an a GUI that runs on a PC.
