Software hacker (C, C++), Hardware hacker (mostly general digital electronics, Atmel microcontrollers, next step will be FPGAs). Have a CNC machine at home operating with my own motor controller software
A little bit of woodworking (building my own furniture).
Espresso addict.
I like to play with LEDs
like writing this rpi-rgb-led-matrix software to control cheap RGB LED matrices with the Raspberry Pi (http://youtu.be/ZglGuMaKvpY)
.. or was involved in the award winning Noisebridge FlaschenTaschen (Code here)
.. or the resulting http://spixels.org/ code and PCB to control up to 16 SPI RGB LED strips.
One of my current projects is to build a controller for 3D printers, CNC machines and laser cutters: The BeagleG software and a cape for the Beaglebone Black.
I made the RFID reader system that gets you into Noisebridge. Also a running Noisebridge project is the electronic parts organization tool.
Here are some pictures I took at the Noisebridge Toorcamp tour 2012
