IC Refrigerator Bug





Introduction: IC Refrigerator Bug

This is how to make a refrigerator magnet from an old IC. I like it because a) it's geeky, b) it looks like a mutant centipede is crawling across the fridge and c) it is from an ancient Apple II card. Be sure to check out Aeshir's version of this.

Step 1: As Always, Collect Your Materials...

As alway, the first step is to collect the stuff you need. I hate it when I almost done with a project and discover that I forgot to track down some dinky 50 cent part. The list is pretty short on this project.

1. A suitable IC. I pulled mine off a card that says "Super Serial Card," and my dad, a former Apple technician, says that it was for connecting a printer to an Apple II. It's easier if they are in a socket so you don't have to desolder it.
2. A magnet. I used some old magnet strip that I had lying around. I would recommend finding something a bit stronger than that, simply because it will hold more. Make sure that you find a magnet that fits under your IC, or find an IC that fits over your magnet.
3. Glue. I used CA (superglue), use whatever you want. Superglue I know works, contact cement will almost definitely work, epoxy might work, Elmer's School Glue won't work.
4. A spacer (if necessary). You might need something to raise the magnet up. A bit of plastic, a popsicle stick, cardboard, whatever. You're creative, or you wouldn't be reading this. Figure it out.
5. A fridge. Why make a magnet if you don't have a refrigerator to stick it on?

Step 2: Sizing the Magnet

Make sure that the magnet fits neatly between the pins of the IC. If you are using a flexible magnet strip, which I no longer recommend, trim it down to fit. Also, make sure that the magnet is taller than the pins, especially if you use magnet strips. Distance is critical with magnets.

Step 3: Glue It Together

This is kind of a self explanatory step. Remember: superglue is dangerous stuff. Besides the obvious danger of gluing your fingers together (acetone dissolves it), CA gives off cyanide gas when heated, or if it contacts Styrofoam. Cyanide burns every membrane on your face, and is not fun.

Step 4: Stick It to the Fridge

If you can't figure out how to do this step, you may need professional help. This makes an entertaining bug for your refrigerator. Just remember to wait until the glue dries or you'll give "permanent magnet" a new meaning. I should mention that the magnet was about 1/64" shorter than the pins, so I snipped off about 1/32" from each pin. It sticks much better now. Lesson learned: with weak magnets, contact is crucial.

    i did this with a 40 pin chip out of an old ps/2 keyboard that one hes using there is only a 24 pin. btw good job on the instructable it was quick, and easy just the way i like it

    That is perhaps the largest chip i have ever seen, Apple B card?

    man its so hard to read this its not that you write bad is that i have to load the page in every step it takes like a minute to load a page and i have to keep doing in ;( i dont like thes pro things maybe il just go somewhere else

    Don't we all love them microchips. Stinks I can't make one, all of our old computers are "too precious to be destroyed." Its not like I use them. Well good luck in the contest, a robot shirt awaits us all. I am proud to be individualistic and used an altoids tin, check it out :P

    Why don't you just make a trip down to your local Radio Shack? IC's are <$1.00 a lot of the time :D

    yea but that would be a waste of a good ic. If your gonna do this might as well use a busted up one

    That's not the point, it's a good IC why use it for something like this. It is cool though.

    I see that Chloride and you have a point, though just dig around in the couch a little or just go to a junkyard

    wow, great idea
    Now I have a use for broken ICs =)

    Oh, yeah, I have one of those in a infrared wall sensing wheel robot kit. Thanks. I wasn't sure what is was.

    Today must be microchip magnet day!

    Just FYI if interested: That chip would have come from the 4-inch line at NCR and was manufactured during week 50 of 1990.

    See this for more NCR microchip magnet geekiness, except using a really strange package.

    Oh and you should add the fridgemagnet_challenge tag to your instructable.

    I think you have to unpublish it then republish with the tags. By the way, i've added a link to your instructable in my intro. Here's a link to mine.

    AAAGH NOOOOOOO!!! I'm working on an instructable just like this now! FRACK!
