Step 1: What You Need...

Picture of What You Need...
You will need a few things to make the Telekinetic Pen:

1. Fine Point Sharpie, any color
2. Soda Straw
3. Coffee Stirrer
4. Energizer 9 Volt battery (Yes, it HAS to be an Energizer)
5. Crayon, any color
6. MAKE Telekinetic Pen Kit or a pager motor, magnetic reed switch, spring, washer, brass tube and pin.

Step 2: Tools and other stuff...

Picture of Tools and other stuff...
You will need the standard tools; soldering station & solder, drill & 1/16" & 11/32" drill bits, wire stripper, x-acto knife or razor blade, hot glue gun, wire, neodymium magnet, small washer.

Step 3: Prepare the assembly...

Picture of Prepare the assembly...
1. Insert the crayon in the tube and drill a 1/16" hole as close to the end of the tube as is reasonable. The crayon serves as a cushion and support for the drill bit. Works great!

2. Solder one lead from the reed switch to the pager motor and solder a piece of wire about 3" long to the other connection on the pager motor.

3. Cut a small piece of coffee stirrer and insert it over the body of the reed switch.

Step 4: Finish the assembly...

Week 5 Telekinetic Pen_013.bmp
Afterhacking open the Energizer battery use one of the AAAA batteries you will find as the power source. I made a small piece of wire and wrapped it tightly around the button end of the battery and secured it will hot glue. Then solder the other end of the wire to the remaining contact on the reed switch. Slip a piece of straw over the reed switch and the pager motor. Insert the completed assembly into the brass tube and solder the remaining wire to the very edge of the tube. That's the ground contact. Test the pager motor by holding a magnet near the reed switch. The motor should spin/vibrate.

Anyone considering this might like to check out this site:

If you scroll about 2/3 of the way down, they are selling neodymium magnet rings, people won't suspect you're carrying a magnet.
(Note: not affiliated in any way with the site, just thought it was a good idea)

You wouldn't want to wear that ring near a Hard Drive, or any electronic equipment for that matter.

Nah, it won't do anything, I put a stack of 10 1 inch by 1/4 inch thick N40 neodymium magnets on a hard drive and let it run overnight, next morning, all the data was there. Tried moving it around and still nothing. If you want to erase a hard drive you really need a deqausing field. Maybe one of those 5 pound monsters from united nuclear would do something but it would probably just burn up the motor from CEMF in the disc. before it did anything to the data.
Had to repair a computer once where the girl had on a magnetic bracelet while working on her laptop. needless to say, she didn't "erase" anything but the head crash she caused when the magnet pulled and stuck to it really did a number on it.
she didn't feel or hear a thing.. it just started clicking on her. Wasn't until I opened it and said, "WTH did you do, wave a magnet over it?" that she mentioned her bracelet.

I'm fairly sure most hard drives wouldn't care (the magnetic field strength drops proportionally to the square of distance from the magnet and since hard drives also have a fairly solid metal shell, erasing them with permanent magnets isn't as easy as you might think). Definitely will want to stay away from any CRT screens you still have around though, as well as the magnetic stripes on your credit cards. The actual biggest concern I'd have with one of these is that it makes friends with some large immovable object (with your hand still attached) and shatters into a bunch of small sharp pieces. NIB magnets have a tendency to do that.
You do have to be careful with ipod classics and other mobile HDD devices, as they lack such a shell.

About CRT screens + magnets, I remember one day, in first grade, when we were all given permanent magnets and were told to go around the room finding magnetic things. One of my friends, not knowing any better, stuck a permanent magnet on the CRT screen of an iMac (you, know, the old ones that were made of colored plastic and didn't have a floppy drive?). He said, "Look! The computer is magnetic!" The screen had a big, rectangular dot in it from that point on. I can't remember whether it was fixed or replaced, but that was my first lesson about magnets and computers.

Excellent suggestion! Thanks. I did not know they existed. Would have made this a better project.

i bought a reed switch but it only closes when a magnet is actually touching it, so it didnt work

i made it and it fooled everyone

Or you could inject some plasmids in your left arm and throw it across the room.
That sounds just a little bit...hmmmmm, how should I say it.......INSANE!
plasmids???? ok someone give the stupid guy a definition!!! please
you know, plasmids! the special serums made from processed stem cells that introduce special stem cells into the body, allowing for genetic modification and real time mutation, even giving the user what some might call "super powers".
oh yayayaya gotcha
Hmmm... Indeed
where do you learn to do all this... AWSOME STUFF?! and where can i get copies of make magazine in australia?

Yeah, thats what I wanna know

hey i am trying to make this crapy aa light i got from energizer or duracell into a 6 watt led light and i was using some methods from the tactical light you did and i ran into a problem the leads on the led are tiny i need to make them longer i have a soldering iron but don't know how to use it. i was wondering if there things you can buy that you can clamp or crimp to wires that can work as extending leads thanks and any info will help. ps: Kipkay Rocks!!!!!!!!!!!!!!!!
Alligator clips. you can buy them at Radioshack or a hobby store.
dollar store aka .99 cents store

Very complicated for this kind of trick, but awesome! Alternative not as amazing method: put a magnet in the cap of a normal sharpie. Wear a magnet on your ring. WOW! The sharpie moves! (Or put the magnet under the table and move it with your knee)

I'll try to be nice on this one,but i don't understand why in the do they come up with something as saying that inside a 9v battery,you'll find a bunch of little bateryes that is so unprofessional and mean...
"unprofessional and mean..." You can find aaa batteries in 9v ones, its only works for Energizer and Duracell batteries.
actually, it's AAAA (quadruple A batteries).
thats wat i meant, typo...
