Bluetooth 4.0 module + arduino

I am interested in an arduino bluetooth low energy kit. like this one http://blog.onlycoin.com/posts/2013/10/3/coin-arduino-ble-dev-kit But they stopped manufacturing it. And they have no plan on making new boards.

They have published all the source files on github lately https://github.com/CoinApps/arduino-ble-dev-kit do you think that it is a good idea to manufacture a second batch based on their files?

Interesting.

How to start, a crow founding?

The first thing to do is find out why this crowd stopped manufacture.

If you can't find that out, it's probably not a good idea.
