DIY 3D Laser Spirograph with Arduino

 At the WTH blog they've demonstrated a fun project that creates some amazing lighting effects with a range of inexpensive parts. It's a laser spirograph - that consists of three enclosed cooling fans (similar to those found in PC power supplies) that each have a small mirror on one of their blades. The fans are mounted in a way that when a low-power laser is pointed inside the beam can reflect via all three mirrors as the fans rotate. With the Arduino controlling the fan speed via PWM - the effects are fascinating - for example:

Fantastic. If you make your own version, be careful not to point the laser at anyone eye! Click here for the project page. And for more, we're on twitter and Google+, so follow us for news and product updates as well.

If Arduino is new to you, but you're not sure how to to start with it - then the best way to learn is with out new Experimenter's Kit for Arduino:

The package includes a wide variety of parts, sensors and modules including: a servo motor, lights, buttons, switches, sound, sensors, breadboard, wires and more. Furthermore a Freetronics Eleven Arduino-compatible board is included to make this an extensive hobby experimenter, inventor and starter kit. However we don't leave you alone to figure it all out, included is a great project and instruction booklet, plus access to a supporting web page and software examples. In other words - this is everything you need to get started for a fun range of electronics and Arduino related projects! 

So to get started or for more information and to order, check out the product page.
