Introduction: Make a 1/4 Inch Adaptor Necklace
Ever wanted to have an item that was wearable, stylish and useful? Well, here you have it. This necklace can be used for its original purpose and as a form of expressing your love for audio-related stuff .
All you need is:
A ball chain
A 1/8 Inch Female (3.5mm) to 1/4 Inch Male(6.35 mm) Audio Adaptor
Dremel/Cordless drill
A 4mm drill bit
A drawing pin or pointed knife
WARNING: depending on which brand of adaptor you have, you may have to alter the steps to suit it, so that the adaptor is still usable when drilled. Some adaptors have completely metal insides, and without a metal drill bit, this instructable won't work.
Step 1: Press Drawing Pin/knife Into Either Side of the Adaptor
First of all, press your pointy tool of choice into either side of the adaptor, as to leave a mark, similiar to a pilot hole. I recommend doing this near the top of the insulated part of the adaptor, but not too close to the entrance hole of the 1/8 inch jack. 4 to 6 mm is ideal.
Step 2: Drill
Drill a 4mm hole straight through the adaptor, going through the pilot dots.
Try to avoid the metal areas. This may take some trial and error.
Step 3: Thread Ball Chain Through and Wear
Grab your ball chain and thread it through the holes you just drilled.
Loop the chain around you neck, secure the end, and wear. Enough said.
Hope you enjoy wearing this as much as I did! :)
Suggestions welcome.

Too bad- looks like you have to take off the neckalce and take the chain out in order for it to work, it would be kind of cool to be able to use it with the chain still there... Nice aesthetic, though.

You could always hot glue the chain on the outside. Then you could use the adaptor with the chain attached.

Yeah, I was thinking after making it, I could cut the chain, then glue the cut ends to the adaptor. I don't trust my super-glue though, and I don;t want to have a glob of glue on it.

I would use hot glue and then you can easily cut away the excess

yeah, what might have worked better is cutting a groove in the plastic and tying the cord/chain around it.

When you drill the hole, does it go all the way through the adapter? If so, does the adapter still work?

I think I'll be the one to suggest putting it in a vise or something to avoid a horrible drill injury from holding something an inch or less from the bit while drilling.

That's a great idea.! =D
Instead of an adaptor i used the end of my old not-working-anymore earphones and it looks awesome.! x)

Can you think of any reason why this can't be done with a 1/4" to 1/8" adapter?
