Turn Arduino into an ISP programmer

Yes

I was using it to program the Bootloader on the BT boards.

the instructions are not super simple yet, i'm working on writing a better tutorial.

The board is in production now, I'll have an exact date this week. It took us a lot of time because making it easy to use is not so simple... now you can download the code via bluetooth which is quite cool :slight_smile:
