With Adafruit's most excellent Pi Cobbler breakout ! Here I've put together the LEds and switch for a simple model of a British Pedestrian Crossing using wiringPi !
The above image was created during a 4 second exposure with a vertical line of 4 LEDs which are turned on and off at the appropriate times with a GPIO shell script running on a Raspberry Pi. While the script was running I slid the breadboard across the frame.
Sanguino is an open source Arduino-compatible microcontroller board that is based on the Arduino, and inspired by the Boarduino form-factor. It uses the atmega644P chip which has 4x the memory, ram and 12 more GPIO pins than the Arduino's atmega168.

This is the very first Next Hope prototype to work. It was taken before the flux was cleaned off, and the image has been cropped.
Enabling PWM for the backlight pin seems to mux *all* PWM pins to PWM mode, which isn't good if you're using them in GPIO mode already to toggle other logic

'Hello Pond' is the new 'Hello world'.
I'm converting my Little Box of Poems from Arduino to RaspberryPi.
The thermal printer is connected to serial pins on the Raspberry Pi. I'm programming the screenless and keyboardless Pi using an SSH session to log into the Pi in a terminal window on my netbook. If you look carefully you can see my ham-fisted attempts at getting my first ever Python scripts to run. Behind you can see www.geekgurldiaries.blogspot.co.uk/
I had to take the lid off my PiBow case to get to the GPIO pins using the male-female connectors I have.

I used a few 603 .1uf caps where it called for 402's. Sorry SMD gods for such blasphemy.

The Pmod8LD is a set of 8 high-bright LEDs that are each individually driven by a logic-level transistor.
1st gen raspberry pi using an ULN2003 to drive Sainsmart 4 channel relay board. Works great using 5 volts from gpio :)
Should really be able to get up to many MHz using optimized assembly (limited by peripheral clock, not the faster 72MHz CPU clock as you might expect). This shot taken from output from our handy dandy interactive hardware test program: gist.github.com/380091
Fair amount of voltage jump on the transitions. Possibly exacerbated by el cheapo scope probes attached to flying test leads...
Intel J1900 2GHz (2.4GHz burst) Quad core 22nm CPU
8GB DDR3L 1333MHz SODIMM
SATA, mSATA, Gigabit Ethernet, VGA, LVDS, HDMI, USB3, RS-232, GPIO, Mini PCIe, HD Audio I/O
Runs Debian with:
MySQL, Apache, PHP, DNS, DHCPd, Samba, TFTP (for PXE Client boot), Zoneminder, Postfix, Dovecot and KVM to virtualise ½ dozen websites hosted through a LAMP server.
It uses a single 12 Volt supply at < 1 Amp. Fanless.
It'll do for year 2015.
Meh, I want 128 cores at 32GHz for < 3.3 Volts at < 100mA and the moon on a stick please.
Raspberry Pi Zero WiFi and Hammer Header from Microcenter - the header was more than the Pi Zero (5bux usd)
With the help of a few google searches I connected a LCD shield for an Arduino to my Raspberry Pi using a Python-script, just to see if it could be done. Lying on top of my German Atari TT-keyboard.
I used this url: [learn.adafruit.com/drive-a-16x2-lcd-directly-with-a-raspb...] to find out how to connect it, this [www.raspberrypi-spy.co.uk/2012/06/simple-guide-to-the-rpi...] to map the pins on the Pi, and this [www.hobbytronics.co.uk/arduino-lcd-keypad-shield] to find out the pins on the shield.
