I was playing with a laser cutter lately and this is the outcome. A robotic lamp that follows your movements with an optical flow sensor from a computer mouse and an ATMega 328.
I’ll release the files and schematics when I’ve fixed a few mechanical bugs.

A nice little appliance that displays up to 8 different metrics. Powered by a Raspberry Pi.
This is a cheap electronic name badge that can be programmed with the arduino ide. I built it for events like barcamps at the attraktor makerspace.
Q:Great work with the RFM12B, looking forward to trying this out on the RaspberryPi. Are you aware that the SPI bus now has drivers on Pi ? I assume this will help bit rate ?
Yes, I got my Pi last week and I’m working on it. SPI works great but I’m still missing interrupt support for the gpio pins. I guess it will be in the stock kernel when I’m done - I want to add a web interface for configuring the nodes and sending data to/from them and that will take some time :)
Printing a molecule - Part 2
I finally found the patience to finish this.
Because of the very unregular stucture i had to added some support structure to the print. That means that the overhanging parts are supported by a grid of extruded plastic that is extruded at lower speeds.
The printing process:
All the parts with a grid-like structure are support material.
