The first picture shows the reed switch which we will use. It's a glass tube with two contacts which are pulled towards each other making contact when a magnetic field is present. You can reed(read ;-) ) more details on wikipedia. http://en.wikipedia.org/wiki/Reed_switch


<p>Mount the magnet in the mouse so you don't use it and bypass the pc switch altogether to simply turn on your pc with the mouse. Not likely to loose the mouse and if you do, you bigger problems :) Good Instructable btw!</p>
<p>* so you don't (loose) it</p>
Hard drives have two extremely powerful magnets inside them.<br>WAY, WAY more powerful than the magnet in this instructible.<br>No one is ever concerned about getting their hard drives too close<br>to other magnetically sensitive materials.<br><br>Your concern is good, but flawed :-)
Useful information. I was pretty skeptical about that answer.. but you're right. I stand corrected.<br/><a rel="nofollow" href="http://www.pcworld.com/article/116572/busting_the_biggest_pc_myths.html">http://www.pcworld.com/article/116572/busting_the_biggest_pc_myths.html</a><br/>
Ha ha ha Exactly! Not so smart.
Your video was removed by Metacafe.&nbsp; I&nbsp;don't suppose you'd make it available again.<br />
very nice. will use.
Mouser is where I go for most of my discrete components.<br/>Here is the link to the page in there catalog for reed switches.<br/>The bottom ones are truly tiny little things.<br/><a rel="nofollow" href="http://www.mouser.com/catalog/634/1609.pdf">reed switches</a><br/>
Then you go to the back and unplug it =]<br/>
Cool, however harddrives + magnets is not the best combination.
yea?? wont it turn off like wesie said?
....wow... just wow.... NO it WONT turn it off. I wont even bother explaining why. Just live with it.
find a way to mount that magnet in your finger
like they said a ring that is magnatized
More fun with reed switches. How about this one: 1. Build a magnet into a ring. 2. Wire a reed switch into your TV remote control. 3. Irritate everyone you live with, when you're the only one who can change channels.
That. Is. Amazing.
ULTRA WIN! You could pretty much make all your stuff in your house, your car, etc based off of reed switches, if you were so inclined/paranoid.
I installed a momentary push switch into ours due to certain reasons. Now it'll only work if the battery cover is on (for some reason the battery cover would always get lost before, so I used that to incorporate the location of the switch).
This really is a great plan!!!! I may have to try that one :-))))
where do you get the reed switch and are they water proof
In an electronics store, most reed switches are waterproof.
The momentary switch that turns the ATX PC on just completes a short between two pins on the power supply. Inserting the reed switch is just like adding another momentary switch. Once the power supply is turned on it does not matter if the circuit has continuity and therefore the magnet being removed will not cause the PC to turn off.
