Das Uber Airsoft Gun Turret


Hot on the heels of the Wii missile launcher, Das Uber Airsoft Gun Turret is here to put our past airsoft turrets to shame. Made by [Miltron_B], this autonomous beast not only has gorgeous LED indicators, it has lasers. Three of them. Three freaking lasers. Take a moment to wipe the drool from your chin.

We’ve seen plenty of turrets before, but this one really excels in design. It features two webcams for more precision detection and tracking and when set to manual mode, it can be controlled with an XBox 360 controller. He’s posted great pictures of the process with a step by step break down. Tons of useful links are included to help you out.

Someone should construct a Portal sentry gun case for this thing and add voice clips.

RGB laser diode projector


[fl-consult] published this interesting RGB laser diode projector. The build uses three lasers, 532nm green, 660nm red and a 405nm blue diode from an XBox 360 HD-DVD drive. Aside from the salvaged diodes, it uses some off the shelf hardware to power and scan the lasers to make the display. Details are a bit lacking, but google translate helps a bit. If you’re not quite sure what’s going on: the three lasers bounce off of a set of mirrors that scan from side to side as well as up and down to create images.

HP Color LaserJet 2600n teardown


In the ongoing quest to find parts for new projects by scavenging old devices, the curiously sane and benevolent team at Evil Mad Scientist Laboratories took apart an HP Color LaserJet 2600n. They wanted to see what makes it tick and what parts can be culled from it for later use.

Make your coffee with a laser


[Mr Beam] sent this in yesterday, but I didn’t have a chance to get it up til now. These guys are using a 2Kw laser to heat up their instant coffee and tea. Sure, it’s not a hack, but [Eliot] wanted it up, and who doesn’t want their own 2Kw Laser?

Micron laser beam analyser


[David] sent in his laser beam analyzer project. It’s a complete analysis system built from off the shelf hardware. Even if you’re not into lasers, the project combines several technologies that are useful for the hardware hacker. A laser beam is focused to shine onto a spinning reflector. Beam signal is attenuated by adjusting the distance with a stepper actuated sled. The beam is then measured using various sensors.

I thought we were due for a laser hacks category, so I created it and added some of the older laser hacks to it.
