I need to blog about this. This photo includes:
* A Raspberry Pi with a T-Cobbler
* A 20x4 LCD display with negative RGB backlight (currently hard-wired to purple)
Put together, this is a Raspberry Pi running a Python script that uses 3 GPIO pins to control 16 outputs.
Driving the LCD itself is a a dirty, dirty hack that fools some code from Adafruit into thinking it's talking directly to GPIO pins, when really it's talking to my shift registers.
It's that last part which made me bounce in my chair - because I don't quite yet understand how to talk to the LCD display, yet my hack worked the first time. (Albeit very, very slowly.) \o/
In the near future, I want to figure out how to control the red / blue / green backlight pins from the Raspberry Pi, in order to change colors on the display.
I'm developing a number of all-sky cameras for AuroraWatch UK. This timelapse is taken from the first night-time test of the Raspberry Pi version.
No aurora is visible in this timelapse although it was seen during this time from Scotland. For test purposes the camera is facing East, away from light pollution.
Tilly helped me add a button my simple Raspberry Pi internet radio - every time you press the button it goes to the next station.
My first go with Fritzing. And my first go with GitHub.

This one has an adapter that allows me to attach my lensbaby lenses. And a standard tripod screw hole at the bottom.

Components for a flexible mount for the Raspberry Pi Camera module or others uses a camera T-ring as a caged nut to couple to most 42mm T-thread eyepiece or axial port adapters.
I used the clear plastic case that my iPod touch 4G came in to make a case for the Raspberry Pi. I used a Stanley Knife to cut away slots for eithernet, hdmi power and usb.
The elusive Raspberry Pi camera. As difficult to mount as the 'pi itself. If you touch the back too much it will short out and reboot the raspberry pi.
Demonstrating Atmel AVR ISP programming using a Raspberry Pi. I included a FET and tri-state buffer to protect the Raspberry Pi's GPIO. The ATmega1284P is powered from 3.3V but the buffer should allow the Raspberry Pi to be safely connected to a microcontroller powered from 5V.

Im currently installing Fedora so that this Pi can be on display at a event at the end of the month.
