Open source biphasic pulse generator for electrical stimulation of tissues developed by Oliver Schneider at the µOrganoLab & Fraunhofer Institute for Interfacial Engineering and Biotechnology (IGB)
https://github.com/loslab/easypace
Easypace was originally built for pacing cardiac tissues in microfluidic Organ-on-Chip systems, however it can be certainly used for other purposes. It generates adjustable biphasic pulses with frequencies of ~ 0.1-10 Hz, amplitudes of up to ~ 12.5 V and pulsewidths of ~ 1 - 200 ms. Generally it can also be just an idea/ starting point for your own improved pacer 🚀.
- 2 independently controllable pulseforms, 4 outputs in total
- Arduino-based, beginner-friendly assembly, hand-solderable
- manual control as well as scriptable remote control
- fairly cheap (cost of all parts < 100 €)

I'm not a trained electrial engineer, so don't expect a professional build. I tinkered around with Easypace during my phd studies to build a cheap, scaleable system for pacing multiple tissues in cardiac Organ-on-Chip systems which I could adjust to my needs and control remotely. We are happy about any feedback on Easypace. Just tell us if you have any improvement ideas and open a pull request or get in touch via ghilorevilo@posteo.de.
