Scope clock

scope clock
It’s official: build anything with a display tube or a rat’s nest of wires and I’m in love. The project uses a CRT intended for an oscilloscope, but it may be even easier to build if you’ve already got an old CRT scope. Full plans are on the site. Check out the other projects too. He’s got a few Nixie tube clocks with links to board suppliers; very cool.

[thanks yair]

    Phycon, you should go to someplace where people might know the answer to your question. There is a great Apple forum on the support section of Apple’s site.

    phycon-
    what kind of mac is it? the newer ones have hidden power buttons, and older ones do need a keyboard with a power button on it, like the old performa models, i cant remember what model number mine was but it had a power button on the keyboard and when my dad dropped a TV on it (dont ask) we were a bit screwed really.

    thanks for all the help, by the way its a powermac g3 all-in-one. These are pretty rare from what i found out and were manufactured and distributed to only educational groups such as schools, that explains why i got mine at a school auction.
