I've been looking for 12VDC and less-than-12VDC devices - including CPU boards - My USR robotics Ethernet WiFi bridge is 12V (and has an external antenna connector) - the most difficult thing to find seems to be 12V VGA LCD panels - most of those seem to run 17 or 19V... I've been talking to some of the h/w guys at work about this, but no definitive solution, yet... For 12VDC and 5VDC boards that can run Linux (typically headless), you might want to check linuxdevices.com ... > Minus any type of power conditioning I might do, it should run straight > from that. A DC-in to DC-out power supply should be pretty easy (provided the output voltage is something less than the input voltage) - it's been quite some time since I worked with any of that kind of thing, but iirc it's basicly just a matter of sufficient filtering capacitance to take out the ripple... > I'm just going to start with the WRT.

Depending on what you want, you should be able find some very low power, low-heat disapation single board computers at the linuxdevices.com - if you want a more GUI-centric environment, I've noticed that most of the newer e.g. Toshiba laptops and tablets are rated about around 90W - which happens to be the same power rating as one of (the el-cheaper one) the the inverters I picked up last year for around 15 or 20 USD. You can get much better ones (150W and over) for around $100 - and of course, if you hit up Flying J (truckstop - try Opelieka area) you can get the monster 1500W inverters with a builtin Ethernet port for supply monitoring ... (made for big trucks - don't overload your car's 12V system)... --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "CHAOS706.ORG" group.
