Rodeostat: open source potentiostat
The Rodeostat is an open source potentiostat for performing electrochemical measurements which is designed to work with the Teensy 3.2 development board. It is a very flexible instrument with multiple output voltage and current measurement ranges.
- Output voltage ranges: +/- 1, 2, 5, 10 V
- Current measurement ranges: +/- 1, 10, 100, 100 uA

Rodeostat is sold fully assembled in a clear acrylic enclosure with a pre-programmed Teensy 3.2. Also included are: USB cable, set of 3 alligator clip cables and a 50K dummy cell.
The Rodeostat firmware implements many common voltammetric methods e.g., chronoamperometry, linear sweep, cyclic and constant voltage voltammetry. The potentiostat is easily re-programmed with the popular Arduino IDE via the Teensyduino add-on.
Software is available the form of a Python library which enables the users to configure and run voltammetric tests from a host PC. Note, at this time using the Rodeostat requires some programming on the part of the user. A getting started guide and documentation for the python library can be found here http://stuff.iorodeo.com/docs/potentiostat/
Adapters for using screen printed electrodes and additional dummy cell ranges are also available separately in the potentiostat store.
