Dangers involved with using this laser cigarette lighter to start off your smoking session include shooting your eyes out and giving yourself a mean Harry Potter style forehead scar. This thing boasts a two Watt laser diode which has no problem burning everything that comes in contact with it.
[Masterjoa3000] shows you how it was built in the video after the break. You need to acquire the diode and support hardware which acts as a heat sink. These are press-fit together before wires are attached to the positive and negative leads. The housing is just a bit too wide for the wind shield on the lighter, but that is fixed by cutting a ‘V’ out of the center of that shielding. Next comes a minuscule driver board which is soldered to the diode and to a momentary push switch. The switch takes the place of the flint so that pressing down on the striking wheel activates the laser. The whole thing still fits in the unaltered outer case.
Here’s another take on the same idea with the laser pointing in a different direction.

[Madmanmoe64] has really done a fantastic job with this burglar alarm built into a zippo. He crammed a picaxe microcontroller, some IR LEDs, an IR sensor, a battery and various switches in there quite well. It almost closes perfectly, something we think he could remedy if it really bugged him that much.
It has several modes, all initiated by a different sequence of button presses. There is the proximity alarm, which sounds when something moves very close. The reverse proximity alarm which sounds when you remove something from its immediate vicinity. A doorbell mode, and a silent alarm mode. Check out the video after the break to see it in action.

If you’ve ever found yourself thinking, “I wish I had a laser projector hidden in a zippo”, then you’ll really appreciate this project. [Rog8811], who you might remember from the laser lighter, has made a spirograph style green laser projector that fits inside his zippo. This is very compact and you would have no idea it was there until you open it up. Just be careful, this seems perfect for causing eye damage to someone who isn’t expecting a laser to shoot out of your zippo.
