  1. 1. Raspberry Pi An Introduction Alec Clews @alecthegeek http://alecthegeek.github.io
  2. 2. Credit Card Sized Computer
  3. 3. Cheap ● A$42 (http://au.element14.com/) – “Pocket Money” price ● Low power consumption – ~1A (model B) ~700mA (model A) at 3.3V
  4. 4. What do you get for $40? ● Connects to stuff you already have ● Robust ● Cost → Design
  5. 5. Open ● Free and Open Software Stack – Linux – Languages (Scratch, Python, Java, C/C++,...) ● Fully Documented Hardware – GPIO Pins – Build your own – Hardware ecosystem (piface, picobbler,....)
  6. 6. Raspberry Pi vs Arduino ● Linux and multiple lang ● Limited IO ● Single Design ● Reasonable low power ● Growing ecosystem ● No OS, C ● Good IO ● True open HW → Multiple implementations ● Really Low power ● Huge ecosystem
  7. 7. Learning ● Designed to kick start UK secondary school CS ● Programming ● Hardware Interfacing ● “Unfinished” to encourage or force hacking – Boot to console – Python IDLE & Scratch on X desktop – Basic camera add on
  8. 8. Doing ● Science (manage sensor nets,...) ● Home Servers (media, backup, Asterix,...) ● Automotive projects ● Robotics ● PC Replacements ● Home automation
  9. 9. Make $$ ● Create add on products → Ecosystem ● Upgrade existing products ● Create new products ● Port your software Raspberry Pi Foundation, a charity, is cool with you making $$$. Go for it!
  10. 10. Local Projects All these projects are by Melbourne based hackers with various levels of expertise.
  11. 11. Rasbian Rover
  12. 12. Retro Games Console
  13. 13. CCHS Keyless Door Entry
  14. 14. Local Groups ● Melbourne Raspberry Jam – City and Richmond meetings. See meetup.com ● Melb PC in Mount Waverley ● Microcontroller Group – http://www.meetup.com/meetup-group-MXdBjUze/
  15. 15. Further info ● Foundation – http://www.raspberrypi.org/ ● Wiki – http://elinux.org/RPi_Hub ● StackExchange – http://raspberrypi.stackexchange.com/ ●
