Raspberry consumes too much battery: new board for "Rasp"-prototype

A project log for Camera Traps for Citizen Science

Camera Traps can empower local communities & schools to observe & learn about wildlife. We aim to create an affordable DIY solution for all.

As indicated in our first log, we started this project with two potential designs: one based on Arduino (requires more work for the user) and one with Raspberry (less work for the user).

First Raspberry prototype worked very well - however, Raspberry is a greedy little monster that consumes too much battery* !! Jauler has therefore been trying to hack it to make it less energy-greedy, but while this is providing a very resource intensive task (and one of questionable success), and a suggestion during our ThinkCamp Challenge emerged to try a different board, Jauler has now moved on to using this board (STMICROELECTRONICS STM32F429I-DISC1):

He is trying to load Linux on it, and then go from there! TBC!



* one of the goals, that also emerged in collaboration with MammalWeb.org (see our collaboration notes here), is to have the trap active in the field for a month or even longer at a time, while using standard (e.g. AA bateries). That requires a very energy-efficient solution.
