Single Board Computer

I have been looking for a platform to design some camera and automation controls.  I have a PIC development kit from MicroChip.  The problem was that I do not to learn a low level language and chip .architecture.

While reading my Linux Format magazine, I found an article about a new, credit card sized, single board computer called Raspberry Pi.  The computer runs on a stripped down version of Debian Linux.  Great - because I have been dabbling in Linux for several years.

In addition, the operating system includes a version of Python - a high level programming language. Python runs on Apple, Windows, or Linux machines.  A program written on my Windows Vista desttop, should run on my Raspberry Pi!  Just what I was looking for.  I purchased a Raspberry Pi starter kit from MCM Electronics.

With the Linux operating system, there are verions of other programming languages available for experimenting and learning should I wish.  For more information see the Raspberry Pi Foundation web site.

 

What you need

 

If you are a computer collector/geek like me, you probably have everything you need in your parts cabinet.  Here's what you need besides the Raspberry Pi:

  • USB keyboard and mouse (or PS2 keyboard & mouse with adapter cable)
  • SD card (2GB required, 4GB or larger is recommended, allowed up to 128GB)
  • Display (HDMI or composite)
  • 5v 1 amp power supply with micro-usb connector
  • Cables - ethernet and monitor

Before I purchase a Raspberry Pi. I picked up the user guide at a local Barnes & Noble.  Reading most of that book gave me a good idea the the device is one I could enjoy learning and working with.

I purchased a Raspberry Pi bundle from MCM Electronics.  83-14346 - Raspberry Pi Programmers Bundle. The kit includes:

  • Raspberry PI Basic Board Rev. B
  • 5V 1A Micro USB Power Supply
  • Raspberry PI Case
  • 4Gb SD Card without Operating System

Downloaded Raspbian "Wheezy" as the operating system.  Using the instructions on the web site, wrote the operating system to the SD card.

 

Up and Running

Connections to the RPi (Raspberry Pi) are found on "RPI Connections" drawing.

The RPi uses SD card as the storage drive.  I had initialized the SD card and "wheezy" Raspian operating system.  So, when I powered things up, Raspberry Pi booted.  Following directions on the RaspberryPi.org web site, I was able to set up the system running.  Success!

Now, I will be spend some time to learn some Python programming.  Also working on a portable set-up, likely using a tablet as screen.  There may be some add-on boards I may need for design.

Key to the projects I want to work on is programing the GPIO (General Purpose Input Output) ports on the RPi.

 

 

Rasperry Pi Projects

 

Camera Control

Future project plans - camera control for shutter triggering.  I would like to be able to do time-lapse, sound/action triggered photography, and others.
