Chips and Salsa



Some progress with the electrodes has been done! From left to right: base unit, electrode, ground electrode. Ali from Media Factory soldered the tiny SMD’s to the board (like a boss). We still need to attach the resistors and capacitors and some copper before we can test it out.

The PCB’s were designed in Eagle CAD according to [1].

  1. can’t wait to see what kind of readings you get from this and how much “control” you have over the colours in the hat.

  2. Forrest: the components for the circuit were around 25 euros per electrode and 5 euros for the ground electrode. That’s not including the resistors, capacitors and PCB’s which we got from course materials/mlab/DeFa.
