Hey. So the race went off without a hitch last Saturday. The webcam-enabled Fifi was a popular attraction. Here'ss a link to the American Visionary Arts Museum (AVAM) web site.
The final configuration for Fifi-Cam was:
Two 12V solar panel trickle chargers in parallel with two 12 V batteries hooked up to the car charger for my Dell Mini 10v. Camera was Logitech C260. (Solar chargers used for visual effect.) Packed the batteries and netbook and modem in a waterproof plastic bin to protect against water damage during the water challenge.
Verizon wireless broadband modem generously supplied by mp3car.com!
Ran the rig for about 7 hours with no problems! Never drew on the netbook battery.
Streamed via my ustream.tv account on Firefox on Ubuntu 10.10.
All in a success.
