Here’s a DIY coaster plan to put some Saturday Night Fever in your Friday night cocktail. GearCrave found this awesome idea thanks to Instructables, a great DIY blog with some great geeky gadget ideas you can build on your own. This one is a stand-out. The Disco Drink Coasters provide a 10×10 LED pixel display that will play video from your PC via serial port. You handymen can put one together on your own now, thanks to plans on the Instructables website. The rest of us will wait patiently until the wireless versions hit shelves…
