Nice, but I think he's looking to skip the DC to AC conversion and just go DC to DC. Something like a trawling motor battery and voltage regulators for DC to DC conversion. This would be more efficient.
Thinkpads can run off 12V. A car battery will work but you want something to clean it if you use a running vehicle. My brother is very pleased with the regulator IBM makes for this. For other devices, you can probably get away with voltage regulators like 7805, etc. They provide 1 AMP each and I've used them in parallel - YMMV, use proper heat sinks, support circuit, consult the specs and your nearest EE. Happy hacking. Over the outage, someone lent me a generator. I used it to power my UPS and the UPS to run equipment. Laptop life was the limiting factor without the generator. The cable modem and wifi access point ran for hours on the UPS. Overall, I'm glad the power is back. The rest of this was a pain. _______________________________________________ General mailing list [email protected] http://mail.brlug.net/mailman/listinfo/general_brlug.net
