low_cost_potentiostat (PassStat)
Project description
A low cost potentiostat circuit to perform electrochemistry experiments with still high performances. Several implementations are proposed. The system may be driven by a Teensy 3.2 or 3.6 card from PJRC (Arduino IDE) or by power supplies, generator and oscilloscope.
A Python software is provide for PC, Macintosh or Linux operation, and an Android application for Bluetooth remote control. The noise resolution may be below 1 pA while the maximum scan rate may attain 8000 Vs-1.
Below is only a template. Please update using the recommended setup and usage guide
