Though there were no updates for a while, this project is still going on. As planned, I am spending the Hackaday prize money to build and give away Fochica devices. Here is what changed recently:

Switching to using ESP32 devboards in the design instead of AVR Arduinos. The code has been ported to ESP32 and compiles for both Arduino architectures.

Code has been refactored to decouple the build (hardware device + configuration) from the firmware source code. This allows for a cleaner code while supporting various Fochica builds in the past and in the future.

I am now using custom PCBs in the builds instead of perfboards. This is just easier at the current scale.

Building more units and trying various off-the-shelf enclosures.

Several of my friends took the opportunity to participate in the beta and get a free device. At the moment there are over dozen of Fochica installations and I am looking to add more as time and resources allow.
