Oh that's easy, just buy a camp ticket and you will get your rad1o at the camp site!
There is no independent sale right now because we only produced about 4500 badges for the camp's visitors. As many people are asking how to get one, RFguy thinks about organizing a second production run. Be aware that one unit might cost about 200-300 EUR because sponsoring by chip manufactures is not applicable this time. The display and the rechargeable battery won't be included.
We will now talk to a manufacturer to get a production price.
Expect more information about this probably mid to end of september via twitter.
If you don't want to wait, try rad1o exchange.
