A steampunk oscilloscope built by Andrew Smith from parts found in a junk box. "Although not intended to be fully functional it does actually work." It's looks so cute... if you have the DIY skills you can read an article over on electronicsweekly detailing the build, components used and a schematic.
"I discovered that I had a really cute little 7cm CRT in the loft, together with several other valves of different types, and it seemed a good idea to make something decorative with them. For me, a lot of the charm of this piece resides in the unconventional layout and design, using a polished wooden box instead of the more usual metal chassis."
