A new one to me is the Barrie Wireless Amateur Experimenter Group (WAX Group). WAX consists of a bunch of Hams in Barrie, Ontario who like to get together to talk about and build different projects.
Meeting at a local Tim Horton’s coffee shop the group is growing and if you’re in the Barrie area (about 60 kms north of Toronto on Hwy. 400) why not drop by and say hello.
The website has got tons of great links. Check it out. This is good stuff. (If Ham Radio is getting old for you, look at this page of 100+ Things to do in Ham Radio!)
