I was thinking about having some of the board sets made up for this scope clock:

From the looks of the board drawings it is about $200 for a set of three boards from OSH Park, so about $70 a set. There are three boards at 80mm x 100mm and one smaller board about 1/4 that.
I am interested in one set, a friend is interested in another. Anyone else want to try? CRTs are pretty common, it should work with most electrostatic CRTs. I know R5-D3 has some, I have an old 5" one myself.

Re: Scope Clock
That's kind of a cool looking clock. I'm not sure that I need another project, though.

Re: Scope Clock
Anyone who needs CRTs - I've got a ton of them from tek to old PPI radar tubes with a lot in between. I doubt I'll build a clock that eats that much power myself.
I might build a torsion pendulum (quartz fiber suspending a weight) big old granfather type clock at some point. John Bain (post, dammit) is making one, and he's got a fine machine shop.

Posting as just me, not as the forum owner. Everything I say is "in my opinion" and YMMV -- which should go for everyone without saying.
