The most obvious application for a Raspberry Pi is re-creating the sliding red lights found on “KITT” from Knight Rider or the Cylons in Battestar Galactica. This can all be done with pure electronics but that doesn’t involve any programming … Continue reading
It can sometimes be useful to obtain the MAC address of your Raspberry Pi. The Media Access Control address is a unique identifier given to all networked devices. The address is different for all Pi’s and can be used to … Continue reading

I decided to attach some speakers to my Raspberry Pi. I didn’t want to spend much so I picked up a pair of stereo speakers from my local Poundworld. They cost £1 exactly. They aren’t exactly the sort of speakers … Continue reading
The Raspberry Pi is powered by an ARM SOC (System On a Chip) running at 700MHz. It is possible to increase this speed in order to squeeze some extra processing power out of the CPU. It is also possible to … Continue reading
The circuit below shows to turn an LED on and off using a Raspberry Pi GPIO pin configured as an output. It uses the output pin to turn on a transistor which allows the LED to draw current from the 5V … Continue reading
This page aims to give a general introduction to the General Purpose Input Output pins on the Raspberry Pi (Model B). The GPIO pins are available on the PCB via a header and allow you to interface the Pi to … Continue reading

In order to make my Raspberry a bit easier to handle and give it a bit of weight I decided to make a temporary case. It needed to be complete in five minutes, cost nothing and allow for a certain … Continue reading
If you are running the Raspbian operating system you may want to have your Pi auto-login. This may be particularly useful if you are using your Pi to perform a specific operation where you don’t want to login using a keyboard … Continue reading

Here are some initial photos of my two Raspberry Pi Model B’s. One from RS and the other from Farnell Element 14. They are named “Tango” & “Cash” and have matching SanDisk Ultra 8GB Class 6 SD cards. At the moment … Continue reading
The default images provided for the Raspberry Pi are usually 2GB and this results in wasted space on larger SD cards. When the image is written to your card three partitions are created. A boot partition, a Linux system partition … Continue reading
