have you got a total cost for all this?

Thanks all, building this is fun  

Cost/parts of the solar powered RasPI NXT node:
- 1 x CombiBox incl. Solar panel + 1x Empty battery box:             €69,78 EUR (price can be optimiced!)
- 8 x Panasonic NCR18650B 3,6V 3400mAh !!!UNPROTECTED!!!(€6,90 EUR):    €55,20 EUR (best price!)
- 1 x Empty battery box:                               €12,95 EUR (price can be optimiced!)
- 1 x Raspberry PI model B:                            €39,95 EUR (price can be optimiced!)
- 1 x USB Adapter cable mini B-plug - A-plug(connection battery boxes):         €8,95 EUR (price can be optimiced!)
- 1 x USB Adapter cable mini B-plug - A-socket(Solarpanel > battery box):      €8,95 EUR (price can be optimiced!)
- 1 x ISY IWL 2000 Wlan Adapter:                        €19,99 EUR (price can be optimiced!)
- some time to set RasPI up
Done!

Not optimiced complete price is €215,77 EUR. I bougth everything from time to time over some month, not only for NXT

Please do not complain about the price, this is not a consumer product! RasPI is a dev board and so are the components of this prototype. If you need a offgrid RasPI, then this is what works > 30 hours without sunshine!

If you build 100 of em, the optimiced price would come down to half or more
