Solar powered NXT node for conferences!

Berlin conference first! 

I want to support the next conferences with a RasPI completly solar powered in a nice box.
- RasPI model B
- Wlan USB Stick with preconfigured DHCP settings (just turn on wifi tethering on your mobile phone with SSID: NXT, PW: RasPI-NXT)
- Solar panel on top of the box
- 2x Li-Ion battery powerbank (up to 4x 18650 Li-Ion recharchable batterys each) (up to 27'200mAh! It will be able to run NXT node up to 30 hours without Sun!)
(I can sent this to Berlin with batteries included, but not outside germany, so you have to buy the batteries your self)
- open NRS of the RasPI on your mobile phone to show it

All parts will be assembled with latest raspian configured to start up NXT server and login to Wlan 802.11bgn after plugin the power cable of the RasPI.

I will also make a list of all parts, so other conferences can build it's own, because of customs/tax etc.

Some more equipment will arrive next week, then I will also build up odroid U3 and XU (octacore ).

2 photos:
You see 2 cables going into the box, atm the batteries need a first charge with normal 5V/1A powersupplys, it should be done in ~14 hours


And the parts in the box:


If the community like it, I can send it to one of the Berlin conference people. Well, please resend to me when finished

Todo:
- testing odroid U3 + XU
- measure power consumption of all parts, batteries and solar panel to optimice power usage for offgrid solar NXT nodes
- make a list off all pars + weblinks to shops
- howto

Greets,
