    Great instructable! Need this one for sure, sucks having no batteries when you need them and trying to use the useless phone flashlight.

    i specially made a table for my computer :p i don't use any cases :) all stuff are fixed in the table on a piece of plexiglass :) i haven't got any problem so far ^^

    Lol ive built alot of computers with no covers one in a 70mm Ammo case alot of them i never did shut down but to reboot

    I usually leave mine open when it's on. Better air flow. As long as you don't let your pets or small children it's pretty safe.

    But maybe you're cat just came in from outside where it was rainy, or just got done licking itself, or it might have a little metal shaving caught on it's fur. It get's in your computer and next thing you know, you've got a doorstop.

    That is an awesome flashlight! You should enter it in the usb contest!

    DUDE, That thing is a freaking DINOSAUR! Cool flashlight though. :D

    there is a better way to add more leds to the schematic than just one. there was another instructable that showed how to maximize the light output with more leds and with either little or no resistance (meaning lower value resistor or none at all). im not sure who it was by but i know its somewhere around the site.

    what's the point in adding resistors to the LED schematic when they work fine without it?

    in fact it has two purposes ,first and most important is to limit and define the current and second limit the voltage ,thus avoididing to fry the led and closing the voltage so just 0 volts reach the USB negativa voltage limit

    oh i see now...thanks for clearing that up..i'm gona start using resistors now..i've been going without them for a long time...a funny way of looking at it is a man not using a condom for protection and then gettin a disease but with an LED it would fry up instead. hehe (silly, i know)

    ... Theres a new invention its called a GLASS CUTTER anyway theres always ur trusty flamethrower
