Magent jewelry – part 2: Magnetic Heart Bracelet

by on Jan.25, 2011, under quickhack

This is something that I made for my beloved girlfriend.

The heart is made out of some metal that I got from an old hard disk case. I created two equal halves by first sawing out the rough shape from both metal pieces and then sticking them together so I was able to perform the fine working steps on both pieces equally. Then I sawed out the notches for the two magnets. They had to fit really tight because they would be the fastener of the bracelet.

Once the rough metalwork was done I started with the wires. I used phone wire because it is soft and colourful. Once the insulation was removed from the ends of the wires, they could be soldered to the heart pieces by using a hot air gun to heat up the metal and then just the good old soldering iron. The critical point is the length of the wires. Because of the shape of the heart the wires are of varying length. Also, approximating the wrist of my girlfriend was quite hard because every millimeter matters, but I was lucky.

Lastly, I used hot glue to glue the magnets to the heart pieces and to seal off the soldered area from the skin. The hot glue also makes the back side of the heart pieces nice and flat and soft so it is comfortable to wear.

I hope I could give you some Ideas on how to do this on your own. If you have any Ideas and want me to try to put them into practice, tell me! I’d love to!

Update:

Meanwhile, it is broken and I threw it away because I don’t want to be reminded of a girfriend who betrayed me and lied to me.

Magnet jewelry – part 1: Marble necklace

by on Jan.16, 2011, under quickhack

Today I found a solid metal marble and I thought “Hey, that would look nice as a necklace.” The question was, how to attach it to some kind of strap so I can wear it. Well, good thing we have the good old rare earth magnets.

I decided to use two stranded chopper wires to start with. I just stripped the wires and clipped them in between two rare earth magnets. I did this on both ends of my wires. Then I attached the whole thing to the marble and voila:

I found that it looked quite nice so I decided to improve it further.

After a bit of polishing, the marble was looking really nice. To increase the stability of the necklace, I glued the two magnets together. They are really strong, but sometimes the wires just slipped out. The glue solved this problem for now. I also adjusted the length of the wires to fit more tightly.

The fun thing about it is, that you can use the magnet necklace to attach whatever you want. If you didn’t use glue, you can easily change the color of your wires as well. Just go find some small metal object and attach ist. Let me try to find some examples…

Plastic bag

The magnets are even able to hold really heavy objects like a hammer or that strange grabbing device!

The objects do not necessarily need to be magnetic. Just clip anything that is flat enough between the magnets. Unfortunately I didn’t have any gummy bear bags so I had to use that ugly plastic bag with some unidentifiable black plastic things in it.

Caution!

Do not use batteries! Since both, the cables and the magnets, are conductive, you will short the battery. This is dangerous!

I hope I could give you some cool ideas. I had quite a lot of fun experimenting with the magnets.

Try it out for yourself!
