"The final idea was to embed a LED and copper coil assembly inside the titanium ring, illuminating it from under the stones when it was in close proximity to an induced alternating magnetic field. Autodesk Inventor helped me develop all of the dimensions and constraints for the design. Having some help, I was able to obtain her ring size and the rest of the measurements were based from there.

"Here is a stab at the Arduino compatible Sanguino board (albeit simplified). It’s pretty standard except we’ve removed the reset circuitry and alot of the pins. We still have 4 controllable pins, one for the LED and three spare for something fun in future. Once again the plastic was printed before dropping in pre-tinned components and finally printing the metal tracks."

"Here’s a cheap way to build your own fully customisable infrared PC remote control. If you already have a suitable infrared remote control going spare you can build one of these for under £4, it will allow you to use most infrared remote controls to issue keyboard commands on your PC."

"Since I’ve written a Tetris in Python half a year ago, It wasn’t that difficult for me to write this one for the Arduino. Other than the four arrow keys that are also used for the Snake game, another tact switch was added to immediately drop a piece to the bottom."

"There is no denying it, Analogue VGA is on the way out. Which is a shame really, because it is so easy to get an FPGA to drive a few resistors and put a picture up on the screen. It’s a great ‘stretch’ project for the FPGA first-timer. But it does have a downside. Each bit of colour resolution required 1 I/O pin and 2 resistors, and then there is an additional couple of sync pins to."

"During the last months I’ve been working on a 2-wheel balancing robot (also named inverted pendulum). In the meantime you can find a number of similar constructions in the world-wide-web. Most of them are constructions built from self-made parts. Very few use Lego mindstorms parts. I believe that here the first one is described for which fischertechnik components were used. Due to its artistic balancing act I have named this robot ARTIST."

"All of the hardware and software is open (in the GPL sense), including parts lists, circuit board and chassis designs, and software. With a stated goal to produce sub-€100 robots, I’d really like to see this take off. Combined with a wireless power surface, a micro-robot in perpetual motion would make a great desk ornament!"

"The various hardware modules are all open source designs – and I chose to use a mix and match approach to the system which was put together using hardware from a variety of vendors. Compatible devices were used from JeeLabs, Openenergymonitor and Nanode Ltd."

"Ever since I created the 8×8 Led Matrix I wanted to create something bigger. This LED matrix is 16 x 48 LEDs in size. There are 768 individually placed and soldered 3mm green LEDs."

"For our final project, we re-engineered a remote control car to autonomously navigate through a track by detecting lanes and centering itself between them as well as detect objects in front of it and avoid collision. The RC car detects lanes through image input from a low-resolution camera mounted at its front. Using an IR distance sensor, the car determines when to stop accelerating once a certain distance between a forward object has been breached."
