Ham Radio Stuff

Free ham radio class! On-line! But why?

Free ham radio class! On-line! But why? Stuck in your house during COVID? Want to talk to people but don’t want them to see your sequestration hair-do or lack thereof? Wishing you had done more to properly learn electronics? Too much dust on your voltmeter and soldering iron – if you can find them? Think a ham radio license would...

Fix-It Night for Crappy Tire Stuff

We have a bunch tools at ylab, and some of them from Crappy Tire. We can call them that – after all, Canadian Tire fought for the use of that name. You would normally think we would be using their tools to fix other things. Nope. We had to fix the tools. This  Mastercraft drill is about 4 years old, the first 3 1/2 years being unused...

You’re doing *what* with a microwave???

Don’t be a hero. Many pages on the Internet tell you how to make a spot welder from a discarded microwave oven. We always thought it was a crazy idea. And then a couple of the more experienced ylab members told us it made sense and would not result in electrocution or being nuked into a medium-rare meat sack. That explains some of the...
