Status:
I've got the Wiimote connected to a PC and the Smoothboard software. Advice, avoid BlueSoleil bluetooth dongles, you'll need to fork out for an upgrade or try to bypass it. The BlueSoleil website has very poor navigation and they've made it easy to accidentally download shovelware. I had no problems with a laptop that already had bluetooth. I can't find a shop in Adelaide that stocks cheap Infra Red pens or so it's a matter of making one or ordering off the internet. Jaycar stock infra red LEDs
