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 Rodeostat Multiplexer hardware guide The Rodeostat Multiplexer is an expansion board for the Rodeostat potentiostat which enables it to be used with up to seven working electrodes simultaneously. This is achieved by adding a multiplexing switch to the single working electrode channel on the Rodeostat. This switch operates under control of the Rodeostat firmware
Rodeostat Rodeostat Muliplexer Kit getting started guide The multiplexer kit is an add-on accessory for the Rodeostat 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 this guide we describe how to connect the multiplexer expansion board to
pH Featherwing The pH FeatherWing hardware guide The pH FeatherWing is a single channel pH electrode amplifier based on Texas Instrument's LMP7721 ultra low input bias current (3 fA) precision operational amplifier. The design of the pH electrode amplifier closely follows Texas Instrument's "AN-1852 Designing With pH Electrodes" application note. It is compatible with Adafruit's
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
