@coldclimate and @sc_r making things during howduino

Howduino, what a great event/weekend at the centre for life.
So we had two days of 6 hours each to make stuff around arduino or electronics in general. There were a lot of matrix light projects from @coldclimates and @sc_r s ping pong matrixes, to lee and friends amazing skip finds (two great matrix displays). Another theme was that of remote controll, with @alistair controlling a servo over the internet, and another team a remote controll car from their computer.
There was also the hacking of an animatronic head(yoda like) and the control of housegold power sockets(peter) through a networked arduino. Sophie did a squigglebot, and there was a whiteboard drawer, thom did a dalek that found your face (using the webcam) and pointed his blue led laser gun at you. @oomlout contributed to a lot of the projects, and jim of @sonodrome demoed using a led as an input(light detecting) and output(light  o) device, nice one
These are all the ones I remember, but it would be great to get a complete list.

What did I do?
Investigated using a ldr to get an idea of motor spin speed. In the future this will be great for getting an idea of how fast a centrifuge is spinning, or using it as a counter for bees entering and leaving a beehive.
