I stumbled across a working Rubik’s Cube made from Legos. The design is by Maarten Steurbaut, and it is an impressive compact design (his second version). Below is a MLCAD/POV Ray image of the inner workings of his cube.
His first design was much more complex (below), and I find the images to be quite impressive. [...]

As reported on PCSTATS, Research in Motion (RIM) engineer Matthias Wendel designed a Lego Machine to test their Blackberry Pagers. The machine rotates the pager about two axes in a pre-programmed manner allowing the engineer to systematically test the reception of the 900 MHz wireless device in the environment.
This is an excellent example of how [...]

I am slowly constructing my first intelligent instrument. It will be an instrument that learns the acoustic radiation pattern emitted by a speaker. It is not a perfect acoustic experiment—nor is it meant to be. Uncertainties and errors abound, especially since I am using the Lego NXT Mindstorms system to construct the instrument.
The design is [...]

I recently designed a Geneva Mechanism that I will be using in my Lego Laser Scanner. The Geneva Mechanism takes smooth rotary motion and converts it to intermittent rotary motion. One can think of it in electronics terms as changing the duty cycle of the oscillation.
Geneva mechanisms were invented in Switzerland for use in clockwork [...]

Well, I must admit that it didn’t take long for my interest in robots to be united with my interest in lasers. Two great tastes that go great together! Why indeed should my robots be defenseless against those that might wish them harm? Clearly, a Lego Laser is called for.
In all seriousness, it occurred to me [...]
