Andrew Smith built this stately and elegant "toy oscilloscope" that actually works but, he says, is more "intended to be a decorative conversation piece." He made his plans available via Electronics Weekly's Gadget Freak. From the project page:
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.
I have made several other projects in this genre which can be found here. I use pieces of mahogany strip left over from a hardwood floor; scrap material of this kind is readily available from local flooring companies, and with simple hand tools very satisfying results can be gained. There is an intended reference to the form of construction used for electrical equipment in the early decades of the last century, but in my hands the genre has gained a life of its own, and has become completely anachronistic.
