Hey,
i just thought it might be interesting to someone to bring RepRap offgrid with a open source solar solution.
I had a solution in mind that would be able to charge LiFePO4 Cells as they become cheaply available over the past years.
As such a controller needs some speed I would recommend to use the ARM cortex M0+ which is the microcontroller of the new zero board from arduino and also seems to be pretty interesting to the whole RepRap project.
I have a conrete design in mind, does anyone is interested to bring RepRap offgrid?
