Following my fiasco with the electromagnetic cuffs last summer (they broke after the first serious use), I started collecting various ideas about making a DIY version.
First of all, have a look at this post:
Electronic bondage, magnets, and mathematics
I (independently) came up with the same idea. Instead of using long cables (which can be disconnected or broken), you can use a local rechargeable battery. The more hours you are going to stay in bondage, the more powerful the battery should be. That means - no time-relays or mechanisms. All you need is a 9V battery and an electromagnet.
So, the basic design is quite simple:
o- handcuffs
o- electromagnet
o- 9v battery
o- metal piece/plate for the second cuff
o- battery case
o- battery connector
o- bolts
o- washers
Electromagnets you can get on eBay:
eBay: holding (electro magnet,electromagnet)
Search eBay UK: holding (electro magnet,electromagnet)
How big should it be? What I could find on eBay is too thick (2cm+).
The metal piece for the second part (any good names for this one?) should look like a cup, so the magnet can easily fit inside. This is to prevent sliding the magnet off the 2nd piece. Also this design will allow to use less strong magnet or less powerful battery.
The batteries. This is easy:
eBay: 9v rechargeable battery
Search eBay UK: 9v rechargeable battery
As you can see, you can find various models: LiIon, NiMH, 250mAh, 300mAh, 600mAh, 680mAH, 780mAh, 880mAh... Pick up several and do not forget a charger:
Connector. Also easy:
eBay: 9v battery connector
Search eBay UK: 9v battery connector
Now comes a more difficult to find "ingredient". The case or holder. I could not find anything rigid and reliable on eBay:
">eBay: "9v battery" (holder,case)
Search eBay UK: "9v battery" (holder,case)
Any ideas?
Cuffs. There are so many to choose from...
eBay: leather lockable wrist cuffs
Search eBay UK: leather lockable wrist cuffs
But I have no idea where to get the metal part that will be hold by the magnet ...
