Nice work, ebereon.
Putting a solar RaspPi NXT node on display at the conferences will give us a unique talking/selling point for NXT, so I think that we need to prioritise these as promo material.
So, 3 points to begin with:
Ebereon: can u put more of these together for both Berlin and Amsterdam canferences ?
I have some conference experience and the chances of just one system surviving 2 conferences is minimal.....
Thanks!
Sure, there is not problem to make more. But keep care of the equipment at the conferences, we wont throw our moneys(NXT) away because of lazyness

If there is something broken after a conference, I can simply repair it!

PS.: The solar NXT node is now running without powersupply. Lets see how long this will run... forever?
