Linux.

 

I'm after some small battery or USB powered iBeacons.

If you were just playing with the technology then you can make a beacon a linux device eg a laptop that has a suitable bluetooth radio.  No idea on the devices otherwise sorry.

Looking to play with an iBeacon or few. Anybody have anything they aren't using (or a good local supplier)? Thanks

 

I'm in Christchurch but happy to pay shipping if needed, won't be much?

If you had a spare one that would be amazing - save me the wait time from AliExpress and allow me to do a proof of concept :-)
