Mykle Hansen likes his unix, his Mac and riding his bike. I can’t figure out too much more from his blog. He did make a kick-ass vest that displays his current speed. He calls it Speed Vest. It uses an Arduino to sense the speed and then display it on the vest using electro-luminescent wires. To make the project just a little cooler, the EL wires are laid out in a nixie tube style. There is separate post that has a video of the Speed-Vest in action. <via OhGizmo!>
