Open Source Russian Vacuum Fluorescent Tube Clock
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."
A long time ago I redirected my child interest in destroying and rebuilding electronics to tinkering with virtual constructs.
So I shouldn't be interested in "hardware hacking"; however, too many hours of fallout, too many zombie movies and too many post apocaliptic novels have given me a degree of interest in that part of the engineering poetry.
Time to go find an open source rifle made from old car parts.
Most people don't the skills to write.
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
Friend: "The NIC is misconfigured..." Me: "No prob, I'll just telnet in and fix it." *Silence*
IMHO this has more geek points.
And what if I want to add a stopwatch or countdown timer mode to it? Or make it count in an alternate base or time system?
Here's a gadget that is cool (from a geek point of view), that you can make yourself (provided you have the skills, you should as a geek), that makes other geeks go "ooooooh" in envy and awe, that glows in flurescent blue (that by itself is already enough) and you dismiss it as something you wouldn't want.
Please drop your geek card in the shredder by the door on your way out, will ya?
We used to have a Bill of Rights. Now, with the rights gone, all we have left is the bill.
You could just rip the clock out of an old VCR.
I'm not sure that the "Open Source" moniker has any relevance to hardware projects like this. In software, the "source code" is the actual raw material that a complied application is made of. In hardware, the "source" is physical electronic components.
I guess you could call the freely-available plans and schematics "the source" but that doesn't make much sense, because without hardware components, you can't compile it into a working device. So the term doesn't really apply, especially as we've had freely available electronic schematics for decades, and nobody ever called them "open source." This terminology just seems to be a way to seem cool and trendy.
... and then they built the supercollider.
Why not? Can nothing be done to correct this?
That's not retro; it has a CPU in it. Look at this all vacuum tube digital clock where all the logic is tubes. 103 tubes.
