FeAtHEr-Cm meets Star Wars

I have this little Star Wars lunch box, and just noticed that it is big enough to fit the Adafruit Feather along with my potentiostat featherwing. What does that mean? I have the most awesome Faraday cage!

And voila! A Faraday cage… if I’m willing to drill holes in the case.

FeAtHEr-Cm gamma tests

I received the PCBs for the gamma (3rd) version of the FeAtHEr-Cm potentiostat. I really like how this one comes together. Complete with 2 20kohm pots for adjusting virtual ground and iR compensation plus the passives all fit in a single 14-pin socket which allows students to explore how changing these components can influence the performance of the instrument (and to hack it to do things it’s not intended to do). Plus, it’s got buttons! This is the version that students will see this fall.
