As we move into working on new products, we thought it might be useful to put together a list of all of our archived open hardware products. Most of the projects listed are no longer actively supported, however the documentation contains useful links to design files, BOMs and make instructions.
While we are no longer supporting the Cheapstat potentiostat, we are actively supporting on our own open hardware potentiostat, which we call the Rodeostat potentiostat. We also have developed a multi-channel version called the Rodeostat Plus and a $20 low-cost Rodeostat FeatherWing.
Open source colorimeter (Kickstarter version)
These design documents are for our original educational colorimeter kit which we funded on Kickstarter in 2012. We are currently developing a new, updated version of the popular open hardware colorimeter, which will have a single machined or 3D printed cuvette holder and easier platform for collecting data. Stay tuned for updates!
