Steampunk Tube Magnets Will Rock Your World!





Introduction: Steampunk Tube Magnets Will Rock Your World!

An Idea to make steampunk fridge magnets came in to me  when I was watching Wild Wild West. I couldn't afford building a giant spider, so I decided to put old broken vacuum tubes I got from my school into a good use.

Step 1: Parts and Tools


Vacuum tubes --- I strongly suggest using old broken ones, because there are better uses for the working ones.

Neodymium magnets --- They are stronger then regular magnets and you can buy them in large quantities on ebay for very low price


Hot Glue Gun --- Available at any hardware store

Step 2: Progress

Just glue a magnet to a vacuum tube. You might need to use 2 magnets for heavy ones.

How many magnets would you use for this one???

Step 3: Smile!!!

I hope to see photos of your fridges!

Step 4: Peace!!!

    to acedocholine, the problem with opening tubes is that the interior instantly oxidizes and frosts the glass which looks horrible. maybe an led behind it would work.

    Not to be intrusive, but may I have the ratings for this tube? If it would be too much trouble to write it all down, may I have the tube's part-number so that I can look up a datasheet? It looks like the kind which would use around 500W just for the filament.

    its a GU39A

    specs are:
    Uf = 6.3V
    If = 85-105A
    Ua = 10KV
    cost = over 100$ at least

    shame he distroid the tube. i would have been nice in a VTTC.

    So true, Doci.

    It's a beautiful collectors' item, anyway..

    Dang. I was close on the 500W estimate.

    Thank you for the information.

    I agree, it would have been great to use in a VTTC. Of course, it may be a bit overkill and have a too-high frequency of operation for large streamers, but overkill is always nice, and who doesn't need a C-class plasma cutter?

    I think this is a nice idea, but just for damaged tubes (like, with blown filaments and stuff like that), since those REALLY can't be used for anything.

    But if the tubes are good, I'd put them to use in a circuit (preamp, a full amplifier, radio... whatever! XD), specially now that I developed a technique to make tube sockets at home (gonna make an instructable for it soon!).
    I was only able to make them for 7-pin or 9-pin miniature tubes, but its something already! :3

    This is one bomb project.
    Deceptively simple...

    I think a name change would give this BA instructable more views.
    Maybe, "DO IT! Steampunk magnets will rock your world!"

    or something to that effect, to attract attention.

    OK. I will change the name :) we will see :D

    I'm not sure if the glass section of the tubes are fragile. If they are, perhaps the tubes could be dipped into a clear liquid plastic or resin of some sort to protect them.

    Since tubes are so hard to get and the ones that are available are best used in sound equipment, perhaps a clever person with glass melting skills could make decorative non-working tubes for art projects. Use cheap test tubes and recycled metal parts from old TV's. If you go to a thrift store/second hand store nowadays, there are dozens of old TV's for sale, very cheap.

    I sure hope these don't work any more. There are much better uses for old stock tubes than silly fridge magnets. It's a good idea, though. Any guitarist who owns a tube amp (like myself) would go nuts if they heard old tubes were being used like this. If you can manage to open the bottom it would look sweet with an LED.
