FED2.0 improves on FED1.0 in the following ways:
- Smaller, cheaper, and easier to build
- More reliable pellet dispensing
- Longer battery life - FED2 should last around 2 weeks on a charge. This can be increased quite a bit with some hardware and code changes (message me if you want details) but we prioritized ease of build and use over battery life.
- FED2.0 has a screen!
TODOs, as of 6/01/18:
- Implement wireless data transfer to watch data in realtime (in progress using Particle Photon and Blynk for visualization).
- Work on RFID for tracking feeding from multiple subjects (this is in progress but it's more complicated than we though!)
FED 2.0 is a redesign of the original FED device developed by Katrina Nguyen and her colleagues in 2016, and published in the Journal of Neuroscience Methods. FED2.0 runs on an Adafruit Feather Adalogger M0, and uses boards and code from Adafruit, Paul Stoffregen's Time library, and Arturo Guadalupi's ZeroRTC library.
