Making an open source COVID-19 face shield

Making an open source COVID-19 face shield

Like many people, we have been alarmed at the reports of the lack of personal protective equipment (PPE) for healthcare workers on the frontlines of the COVID-19 pandemic. We have been following the work of many individuals and groups on social media making open source PPE as we try to

Rodeostat Muliplexer Kit Assembly

Rodeostat Muliplexer Kit Assembly

The multiplexer kit [https://iorodeo.com/products/rodeostat-multiplexer-expansion-kit] is an add-on accessory for the Rodeostat [https://iorodeo.com/collections/cheapstat-open-source-potentiostat/products/potentiostat-shield] which expands the number of working electrodes that can be used with the Rodeostat from one to seven converting it from a single-channel to a multi-channel potentiostat. In

Creating a pH meter using the pH FeatherWing

Creating a pH meter using the pH FeatherWing

In this blog post we demonstrate how to create a pH meter using the pH FeatherWing, an Adafruit Feather M4 Express and a few additional components. The meter will display a continuous readout of the current pH and can be calibrated, via button press, at pH values of 4, 7

Bismuth modified carbon paste electrode for metal measurements

Bismuth modified carbon paste electrode for metal measurements

In the experiments described in this blog post, we made a bismuth modified carbon paste electrode for detecting heavy metals, lead and zinc, using square wave anodic stripping voltammetry and the Rodeostat potentiostat. This is a continuation of our experiments using electrochemistry to measure lead and other heavy metal pollutants
