Introduction

Rodeostat Introduction
The Rodeostat is an open source (hardware and software) potentiostat which is ready-to-use with firmware/software implementing many standard voltammetric methods. One of the main development goals was to make it easy for users to make custom modifications. To enable this the Rodeostat design is base…

Open Source Firmware

Rodeostat firmware guide
In this set of notes we describe how to download, build and install the latest version of the firmware for your Rodeostat. Note, that all Rodeostats purchased from IO Rodeo are pre-programmed with the latest firmware - so if you have just purchased you don’t have to download and install

Electrochemistry Tutorials

Irreversible Cyclic Voltammetry
In this blog post we provide data from our testing of the new Rodeostat. We performed a side-by-side comparison between the Rodeostat and the Cheapstat potentiostat using ascorbate cyclic voltammetry experiments.
Reversible Cyclic Voltammetry
In this blog post we carried out a cyclic voltammetry experiment with ruthenium hexamine Ru(NH3)6 a reversible redox couple.
Electrochemistry: Current dependence on scan rate
In this tutorial we use the Rodeostat potentiostat and a screen printed electrode to demonstrate current dependence on scan rate. We know that for freely-diffusible analytes like ascorbate, the anodic peak current depends linearly on the square root of the scan rate. This is described by the Randles…
Chronoamperometry with glucose test strips
In this electrochemistry experiment we used the Rodeostat[https://iorodeo.com/products/potentiostat-shield] potentiostat to measureglucose in liquids using commonly available glucose test strips. Glucose teststrips are a type of biosensor - they convert biochemical reactions to anelectrochemical…
Bismuth modified carbon paste electrode for metal measurements
In the experiments described in this blog post, we made a bismuth modifiedcarbon paste electrode for detecting heavy metals, lead and zinc, using squarewave anodic stripping voltammetry and the Rodeostat potentiostat. This is acontinuation of our experiments using electrochemistry to measure lead…
Making a custom electrochemical cell
In this blog post we describe making a simple custom electrode mount that we used in cyclic voltammetry experiments with the Rodeostat potentiostat. The electrodes we used were purchased from CH Instruments but the custom mount could be easily modified for use with other electrodes.
Making a carbon paste electrode
In this blog post we describe making a DIY carbon paste electrode using graphite powder/mineral oil mix and a custom-made reusable holder.
