With a heavy deadline looming, the Nanotech team (myself and Nicolas Marechal) held an all night soldering/programming session. Chinese food and bottles of Becks made me feel like it was Wall Street in 1988.
The second part of our project (after the proximity sensors) was finished up and proven to be fully working. This functions much the same way as the proximity part but instead of proximity sensors, pressure pads are used. As someone moves on the pressure pad, more lights turn on and if no-one steps on it they drop down. There's only two of these though.
