Scrapheap challenge

Nerdery in Groningen with the so-called "maker fair". Basically: find all sorts of stuff, throw in some people who like to build stuff with stuff and there you are.

Delayed-action mechanical-propulsion transportation systems in the making :)

Also: robotics, hacking-'contest' (a bit easy), arduino-in-a-smoke-detector so it can send texts (SMS).... Fun :)
