wow now I'm in a bind! The nice thing of this project (OP) is that you have an electronics board and could potentially plug a CO2 meter, thermometer, etc and combine local room data with weather/internet/etc data.

The nice thing of the Kibdle project you share is that hardware-wise is virtually plug and play. I'll probably try the Kindle route first, don't want to mess around with Lipos more than needed.

Thanks for sharing!
