I use a nano-ITX board w/ 12vdc power, works great, runs Linux just fine.
Now that's what I'm talking about! I'm really intrigued by these itx setups, i've done an ac itx box before, but i'm intimidated by running wiring to support it. What nano itx board are you using? What kind of dc dc power supply did you use? What hard/soft-ware do you use to run your sensors? What do you mean by radios?
Sounds like you have the optimum setup for running off battery. For the time being I'm resigned to the fact that I have shore power every night, so I'm thinking about getting a beefy laptop like this beast: Newegg.com - TOSHIBA Qosmio X505-Q850 NoteBook Intel Core i7 720QM 18.4" 6GB Memory DDR3 1066 320GB HDD + 64GB SSD HDD BD Combo NVIDIA GeForce GTS 250M - Laptops / Notebooks
and calling it a day.
I'm still interested in a 12v only system that could serve as low wattage entertainment and as a monitor to show me that it hasn't burned sank or exploded over the internet to me while i'm away.
Do you know a place to find 12v monitors?
