A quick check of prices in the local shops $30 (Aussie dollars) for a replacement, no way I was going to pay that. OK so I'll get it sent back from Perth to Canberra .. that would take at lest 3 days arrrggghh .... I'll get withdrawal symptoms.
Then I remembered seeing the Johny Lee demo of how the Wii remote can be fooled by a pair of infra red transmitters on a pair of glasses. So its out with the Xmas tree lights .. mask all but 2 of them and arrange them about 20cm apart.

Switch them on point the Wii remote at them and hey presto I can control the cursor on screen & select Wii sports. I was amazed t how well it works. At least it will do until I get back to Perth next month.
