It's time for another project contest! In addition to giving out awards and prizes for the best Instructables entered during September, we're also trying out a challenge: document a project that utilizes magnets.
Magnet Challenge
Document a project that uses magnets. Magnets are used in lots of places, so thinking up a project should be easy. Here are some example uses of magnets to get you started (post more in the comments!): motors, earrings, transformers, Rubik’s cubes, refrigerator magnets and lights, knife racks, voice coils and speakers, throwies, reed switches, traffic light triggers, magnetically levitating trains, art, ferrofluid, and bicycle speedometers.
The best five Instructables documenting projects with magnets will win ATC 1000 Helmets cams. We’ve been experimenting with helmet cams and think they can help make documentation easier and more fun. To enter, publish your project anytime during September and add it to the Magnet Challenge group.
September Project Contest
Update!
Wild Planet Toys gave us some Digital Spy Cameras that we'll also give away as part of the September Project Contest. The top 5 projects will win SpyCams and the next 10 projects will win the card readers.
The 10 best Instructables published during the month of September will win a [http://www.sandisk.com/Products/Item(1220)-SDDR-103-SanDisk_MobileMate_SD_Plus5in1_Reader.aspx SanDisk MobileMate SD Plus 5-in-1 Reader] plus a rare earth magnet (a 1/4'' x 1/4'' x1/2'' NdFeB from Amazing Magnets) and some epoxy to make a magnetic memory reader. We always seem to be losing our memory card adapters; I figured if they were magnetically attached to the fridge they might stick around longer.
We’ll also give 25 Honorable Mentions with Instructables patches to sew onto your jacket or bag. Check out the picture of the patch.
Results!
Results are posted in the news section. Congratulations to all the winners!

What I think does not matter as far as the contest goes... but here's my opinion for magnetic projects (all excluding myself :p) ;)
Best Documentation
pronteon and the Magno-Sniffer
MrMunki and the Tic-Tac light
Best use of Materials (recycling etc.)
PeterTheUnGreat and the Magnetic Speed Sensor (plus he has a cool o-scope)
Most Novel Idea (aka originality)
VIRON and the Magnet Powered Telephone (I've never heard of doing that)
Best application of a commercial equivalent
g0pher and the Magnetic Stirrer
Most submissions
For sure: FrenchCrawler (circa 20)
I have no idea award (can't find a use - but interesting nonetheless)
fungus amungus and the waterfall of destiny
AlextheGreat and the brake tower
First Magnetic Project(s) I'm Likely to Build (aka - cool factor & usefulness for me)
Tic-Tac light (modified)
Magno-sniffer (applied as a gauss meter)
Magnetic Stirrer (to make a vortex generator for ambiance)
There's plenty more - I tried to include most of everyone but now it's time to close :p
Electromagnetic remote control can make people move their limbs:
http://www.erowid.org/tech/devices_article1.shtml
<excerpt>
We can use TMS to prevent people from seeing a visual stimulus or make it hard for them to speak", he says. They can also make people move their limbs without any voluntary control. Some of the first studies showed that applying TMS to the brain's temporal lobes, the regions just above the eyebrows, altered the mood of volunteers. When they stimulated the area above the right eyebrow, the volunteer experienced euphoric happiness. When they targeted the left temporal lobe, the subject lapsed into apathy and sadness.
