We design open source hardware science instruments that can be used in lab or field environments. Examples of our hardware include the Rodeostat, which is an open source potentiostat used in electrochemical measurements. We also developed a multi-channel version, the Rodeostat Plus, and a $20 Rodeostat Featherwing, an affordable and flexible version with many of the same capabilities as the original Rodeostat. All of our potentiostats can be used with standard electrochemical cells or with screen-printed electrodes, using one of our adapters. Modified screen-printed electrodes and biosensors in combination with the Rodeostat opens up a huge amount of applications for environmental science such as measuring the amount of lead in soil or water. Another open hardware tool we developed is a colorimeter. This is a very flexible instrument with mnay applications, including measuring contaminants & pollutants in soil & water. The newest version of the colorimeter will be available soon. Sign-up for notifications on availability here: bit.ly/open-colorimeter

In addition to our open hardware devices, we are also committed to contributing to the open hardware science community with resources such as guides and tutorials. We are also documenting current projects such as the environmental gas sensor project, through our weekly newsletter. 

We are always open to collaborations and partnerships, especially with community members & researchers interested in using open hardware tools in neighborhoods impacted by environmental pollution. Let's connect! You can reach us via our contact form.
