The Naked Truth

So what is the Raspberry Pi anyway? Well, it is a small (approximately the size of a "credit card") but fully featured, fully integrated computer with the following features (for the current 512 MB Model B) :
  • CPU : 700 MHz ARM Processor
  • GPU : Broadcom VideoCore IV
  • Memory : 512 Megabytes SDRAM
  • Data Storage : SD/SDHC card slot
  • Video Outputs : HDMI & Analogue RCA Composite Video
  • Audio Outputs : HDMI & Analogue 3.5mm Stereo
  • Network (LAN) : 10/100 Ethernet RJ45
  • Peripherals : 2 x USB 2.0 Ports
  • Low Level Interface : General Purpose Input Output (GPIO) header
  • Power Requirements : 5V DC via Micro USB socket or GPIO header
  • Size : 86mm x 54mm
  • Weight : 45 grammes
And here it is in all it's glory... (please note that the SD card slot is not visible in this photo because it is on the underside of the PCB)


It's not much to look at, but if you consider that it's real world performance is something like a 300MHz Pentium 2, but with graphics capabilities of an Xbox then you've got to admit it's pretty impressive. It's "party piece" is that it is capable of full HD digital video and audio output via HDMI thanks to the powerful onboard graphics processing unit (GPU).

The Raspberry Pi is available from Cut Price Cables for only £39.99 including VAT and free UK delivery. It comes with little in the way of documentation, but I will be covering basic setup in future posts. However here is a Quick Start Guide to get you going in the meantime.

  2. "This photo is perfect except for background which is...". Well, let's say "bad". Have you ever thought like that? Probably, you even made an attempt or two to edit the picture with the ruined Photo Background Editor, to no avail. Surely, not all of us are designers or at least IT savvy. So, here is a way for the rest of humanity to change the back scene of any photograph – the Photo Scissors online tool.
