I like a good dose of steampunk. It just makes everything seem more obvious. I found a post about a home-made oscilloscope on the Brass Goggles blog. It's a great blog about anything and everything to do with steampunk. If you're running a steampunk game and are looking for inspiration then take the time to look through Brass Goggles.
The other reason I wanted to put this post up is that the "Mr A Smith" who built it is not me.
Or is it...?
