Phinnaeus Gage: Pretty cool, eh? Simple, free, ad-less (well, I guess, I have an ad blocker) web hosting, for simple web sites.
check_status: Very cool, thanks, I'll look into it. $1/watt is nice!
RedSky: Indeed I will need a pretty significant battery. I'll have to go with Li or NiMH for weight, and I'd like to size it for 24 hours usage, which means at 15W for FPGA, embedded computer, and phone combined I'm looking at a 30Ah 12V requirement.
NiMH D cells seem to run about 10Ah, so 30 of 'em would do the job and weigh about 11lb. Li-ion should weigh less but cost more and require a better charge controller.
I also have an idea in the works using peltiers with my wood-fired cookstove, and that might reduce my battery needs a bit if I'm going to fire it up every night. I'd have to use it to supplement the solar panel on rainy days or if I use the ham radio much, anyway.
And the RaspberryPi is on my list of possibilities for an embedded controller, thanks!
sclegend: Heh, wouldn't I look interesting walking around with a windmill on my backpack? 'Course, it'd be a good place to mount an antenna...hmmm...
kr105: Good link! Solar is cost-ineffective unless you're subsidized. In my case, tho, it's about the only choice unless I want to carry around a truly huge battery and hit the grid up regularly or beef up my wood-fired generator concept considerably.
Anybody got any other ideas for off-the-grid (portable) power?
