>>1409411Get a Raspberry Pi with PiTFT and whatever peripherals you want for like $100. I think the power requirements are something like 5V 2.5A 12.5watts.
As for 200watts innawoods. The """lightweight""" method will be PC + UPS Battery + Solar. The best method will be PC + UPS Battery + Gas Powered Generator. Both will be heavy, but the genny will be really heavy though there are camping versions like "Earthquake IG800W" which gives out 800watts and weighs something like 20lbs. Gasoline weighs 6.3lbs per gallon. The Earthquake IG800W has a 0.55 gallon fuel tank and that will last about 7-8 hours at 175-200 watt output.
>tfw my desktop uses 600watts and the monitor uses 200watts.I use a 36watt netbook.
