this is a cool idea - I'm going to apply it to my cupboards tomorrow... I've got two magnetic contacts, around 15 white LEDs and a load of wire. As I'm fairly new to this game, what's the best way to power it, and how to hook together the LEDs. Is it just easier to but an LED strip light and plug it to the mains?? thanks for any advice!!

mfacer: Whenever I do a simple project like this my favorite power supply is an old "power brick" transformer. Most everyone has chargers from old cell phones, etc, lying around, I just cut off the "little" end, strip the wire, and solder in place. Make sure to match the right transformer to the right job though, you don't want to have to use too many resistors to drop the voltage.

I would Grind the head of the LED so the light isn't directed it's more of a ambient light,

I made one with a cupboard that has a swinging door and made a switch out of a block of wood the I staple gunned some paper clips to and bent the clips in a way so that when the door closes it pushes the clips apart. not pretty but works and good for a quick job without much stuff

DollarTree $1 store is selling magnetic window alarms that have 4.5 volts
inside them with a reed switch. I'm pretty sure if you picked up off the end of
the reed switch you would get 4.5 volts. Then just a dropping resistor and don't forget to disable the alarm part of the unit. Here's the unit itself.

Use 3 x 1.5 AA batteries if you need more long lasting power and solder
wires from a battery holder to the pins inside where the A77 batteries are normally inside the alarm housing.

Great Idea! Before reading it I had pictured using a microswitch instead of a reed switch. I like the reed switch better....but I would have mounted it near to the front of the drawer instead of the back, that way if you need to silence the light you can just stick a magnet to the switch.

That's a clever solution! Here's a more convenient option...I found these at http://www.davidsteele.com

I had 1st thought of using a microswitch as well but decided the reed would be easier to work with. I had considered that putting the reed swtich closer to the front. The construction of the night stand made it diffult to put the reed switch anywhere else. If I found a smaller one it may have been possible. I'm not often using the drawer for long periods. Also the book light LED used has a switch on the top of it as well if it really needs to be off.
