P1X Gemini Capsule

UPDATE: Winter has come. We have little to no sun. During those dark times I get back to USB power.

Low-tech, High-life

In true low-tech fasion I'm hosting this micro capsule from a €1 microcomputer powered by a solar energy!

Image of the capsule in its natural environment ;) [29.2KB]

Solar-powered means that it is ON-LINE only when there is enough sun thru the day to recharge the battery.

It's a proof-of-concept an a little poligon. My end goal is to have small, cheap and realiable device to host gemini capsules in the rural areas.
