9V LED Lamp

Here’s a simple project that turns a 9V battery into a fully functional LED lamp. You’ll need one new 9V battery, one gutted 9 volt battery, three high intensity LED’s (white, 25.000 mcd - 3,8 volt and 20 mA - 35 degrees), and one magnet. Full instructions here. One drawback:

The benefit of this is that you don’t have any losses in a resistor and the battery will end up lasting longer - but the LED’s will not operate on 100%.

Bump Key



So you’ve heard about Bump Keys, now find out how to make one. Video after the jump.

These are keys with all the cuts at or slightly below the deepest level for a key made by the manufacturer, and a small amount of material removed at the tip, and, where applicable, at the shoulder - the part of the key that prevents the key from entering the lock too deeply
