I used to jump at hacking challenges in high school, blowing off homework and in the summers staying up til 5am. Nowadays I see these and I have to practically tie myself to the ship's mast to not drop everything I'm doing and sink days into it. I couldn't resist with Stripe's CTF but had to quit after I got busy. This one's especially hard because I love tinkering/building embedded devices. I guess the point is please, please keep this running as long as you can so I can have a crack at it when I'm not working day and night =].
