Want to recover cryptographic keys by just looking at a chip's power usage, for the price of a few beers?

Thanks to our lack of knowledge about what an analogue frontend is, we built a atrocious "oscilloscope" for ~5eur (plus a laptop and some code) and managed to extract AES keys from modern high-performance nano-scale computing systems.. specifically an Arduino (Nano). Hopefully we can spark your interest enough to get you to participate in our workshop! If not, at least you can enjoy a whirlwind summary of our failures and complete lack of knowledge about how any of this electronics stuff works.
