Hack a Dead Computer into a Burning Laser!
posted September 30 2010 20:58.32

styropyro shows how you can salvage parts from an old pc and build a burning laser out of it.
The procedure might look simple but always have in mind that when it comes to lasers you must pay full attention and fully understand what you do.
The result is a burning laser that due to the big heatsinks used can stay on for long and thus let you cut or burn more staff.
In the video description you can find more info about the making and some parts.

posted August 30 2010 17:10.02

styropyro shows how to make a handheld 1W 445nm blue laser torch. The good thing is that this laser is focusable which makes it even better for burning things. According to the maker this build will cost around $130, making it cheap for what it provides:). You can watch a video with styropyro burning staff with this beast here and the video description for links to parts used and info.

Cheap and dirty laser range finding
posted July 5 2010 18:01.06

Forrest Higgs wanted a way to measure distance for a robot he is making without the need of ultrasonic rangefinders, only alternative he had was with laser for direct measurement or offset trigonometric measurement.
Since direct measurement lasers cost alot he went with the second option, he placed a web cam and a laser pointer point...

shynet and his friend made the nBot as a school project. The nBot is a moving robot that shoots a laser - the laser hits the opponent team laser detecting sensor (which is a small system attached to an Light Dependent Resistor - LDR). On each hit the opponent robot sends a hit signal to the main server, then the main server calculates the remain...

5 Dollar DIY Laser Show
posted June 21 2010 20:15.25

Jo0ngle is showing the cheapest way of making your own laser show with good results. Most of the materials probably are laying around your haouse or garage so why not make one right now? The result are much better than some more expensive ones and none will believe you when you tell them the cost. Feeding it from a function generator may give better patterns but i dont think it get worse with music.

LEGO MINDSTORMS NXT Laser Guided Vehicle
posted May 12 2010 18:27.35

Daniele Benedettelli made a low cost robot that can localize and navigate indoor. With LEGO MINDSTORMS NXT as build material the vehicle is a dual differential drive robot equipped with a custom made laser scanner, that measures bearings to reflective targets, whose position is known (map). As you can see in the video the accuracy is very good in both positioning and orientation making it a candidate for further applications. You can watch more info and projects here.
