When I started playing with Raspberry Pi, I was a novice in electronics (and I should probably note that I'm still one :-).
But since then, I did learn a few things, and along that journey I also figured out that Raspberry Pi is great little device which can be used as 3.3V programmer for AVR, JTAG, SWD or CC111x devices (and probably more).
I collected all my experiences in presentation embedded below which I had pleasure to present at FSec conference this year. I hope you will find this useful.
