The above LED cube [VoxCube] is being controlled via a Raspberry Pi, using python and the official Raspberry Pi display.
Buttons were setup using the Kivy. Kivy is a Python library which makes creating buttons and events with a touchscreen very easy.
Here is a very good guide on how to get Kivy setup on a Raspberry Pi.

I was fortunate enough to get access to a prototype of Pi-Pan from www.mindsensors.com during their kickstarter.
The kickstarter has finished and they reached their goal. However they will be selling Pi-Pan from www.mindsensors.com at a future date.
Pi-Pan provides Pan and tilt movements for your Raspberry Pi Camera.
Pi-Pan can pan 180 degrees (from left to right) and tilt 110 degrees (top to bottom).
Pi-Pan comes with two servos, a controller board, screws, a mount and instructions. It also comes with some python code that shows how the device can be operated.
(The controller board in the image below is a prototype and the production board will be a lot smaller.)
As of revision 2 boards, there is space to add some header pins to get access to eight more GPIO pins. These are found on the Header 5. Highlighted below.
Here are their functions;
- P5-Pin1 – 5v0
- P5-Pin2 – 3.3v
- P5-Pin3 – GPIO28
- P5-Pin4 – GPIO30
- P5-Pin5 – GPIO29
- P5-Pin6 – GPIO31
- P5-Pin7 – GND
- P5-Pin8 – GND
I needed some more pins for PiBBOT as I want to change my TFT to a character OLED which needed more pins then I had spare, so I decided to make use of these extra pins.
Here are the results, I soldered the head onto the underside of the Pi so I could plug in an IDC cable.
