Open Source Russian Vacuum Fluorescent Tube Clock

Posted by kdawson on from the ice-blue dept.

ptorrone writes "Hacker extraordinaire Ladyada (whose open source hardware projects we have discussed before) has just published a complete how-to, with design document, on making your own open source Russian vacuum fluorescent clock. The vacuum fluorescent tubes aren't as dangerous as (high-voltage) Nixie tubes, and there seem to be more of them available in the world. If you're not interested in building a clock from scratch, you can also pick up a kit version. All the schematics, source code, and files are available on the project's page."

    First off, LadyAda is awesome. I really don't need to say any more than that.

    I've been wanting to make something like this for a while now. A year or two ago, I bought a big box of the same old Soviet 'vacuum fluorescent indicator' tubes, but I was always having trouble working out the hardware involved, especially the power supply. Using a boost converter is a great idea which might have occurred to me if I had had any experience with them at the time. (Other projects have since taken priority)

    My enclosure design wasn't quite as...ah, 'conservative' as a nice simple laser-cut plexiglass box though :) http://media.giantpachinkomachineofdoom.com/blog/2008-06/images/clockwip3.png

    Now I'm going to have to take another try at it! :D

  2. Cute, but how about this. by lurcher · · Score: 5, Interesting

    IMHO this has more geek points.

    I respectfully disagree.

    RMS himself, the holy fanatic of free software, has compared swapping code to swapping recipes for cooking.

    Open source and by extension free software is about unrestricted access to the instructions for making something. If this something is a computer program, a piece of hardware, a meal, a knitted sweater or a bottle rocket is irrelevant.

    Granted, the term open source as understood by this community is most often applied to software. But the open source model can be successfully applied to any instructions that can be shared and improved upon. I dare you to dig a little, there is a lot more of this "open source" stuff out there than software.
