What I want to do
Broadcast our progress as my dad and I install solar PV panels on my roof, using the balloon kit for a great perspective.
My attempt and results
So far it's going great :-)
solar.batsig.nl should offer a live feed of our progress over the next few days. Right now it's updating every 10s since I was testing range, but when this battery runs out I'll likely bump it to a 1m/5m interval or so. Source code is at https://github.com/natevw/fishgoblub/tree/solar
Questions and next steps
There's a lot of hops, so the live feed isn't always quite as reliable as I'd like. The biggest issue is probably battery life. I'm using http://chdk.wikia.com/wiki/Battery_Intervalometer which seems to help, but I suspect the Eye-Fi is a significant additional drain, especially at the edge of WiFi connectivity.
