IO Rodeo Open Source Potentiostat Shield

We have recently been working on a new potentiostat shield. The potentiostat shield is an open source potentiostat for performing electrochemical measurements which is designed to work with the teensy 3.2 development board.  The potentiostat shield is easily programmed with the popular Arduino IDE (Teensyduino) which enables users to expand the design as it is easily hackable with popular, well-documented tools. Multiple voltage and current ranges making it a very flexible instrument.  Below is an image of a prototype (Teensy not shown). Hardware Some of the main features include: Designed as a shield for teensy 3.2 development board. 12-bit voltage output with four range...

Potentiostat dummy cells

Potentiostat dummy cells

One of our most frequently asked questions on the Forums and via email is how to produce a calibration for the Cheapstat potentiostat. The Cheapstat potentiostat returns measured current values as raw unitless integers read from the ADC (analog to digital converter) at the output of the transimpedance amplifier (current to voltage converter). These integer values are proportional to the current flowing into the working electrode. To convert these unitless integer values to current measurements you need to use a calibration. This can be done using a dummy cell consisting of a single resistor of known value R.  We recently designed a potentiostat...
