This presentation from the University of Medical School describes the use of Raspberry Pi as a potential solution to common challenges in resource-constrained areas, such as high technology cost, limited technology availability (equipment, understaffed dept.), and unpredictable infrastructure. By overcoming these barriers we can improve access to digital learning in developing countries.

  • 4. Common Challenges to Digital Learning in Developing Countries •  High technology cost •  Limited technology availability (equipment, understaffed dept.) •  Unpredictable infrastructure noii’s, flickr lydia_shiningbrightly, flickr
  • 5. Remember Kathleen’s January Show and Tell: Amitava’s Proposed Model
  • 6. What if you could… •  provide a local wireless network … •  provide content via web browser … •  provide content via file or app server … •  do this with or without the Internet … •  do it with or without an electrical outlet … Buy the supplies from Amazon.com, you could do all of this for ~$200 … greencolander, flickr
  • 7. Hardware - Raspberry Pi and accessories Asim Bijarani, flickr •  An ARM GNU/Linux box (Model B): ……………… $25 •  Plastic case: …………… $10 •  WiFi adapter: ………….. $10 •  USB 128GB thumb drive:$60 •  USB 1TB external drive: $80 •  USB ultra-mini hub: ……. $10 •  Rechargeable Battery Pack: …………………………... $40
  • 8. What about lack of available techies? •  Just plug it in … or unplug it when done •  Wireless network name: UMMSPI •  Server name: www.ummspi.net •  If you want to be a “techie” •  User name: pi •  Password: XXXXXXXXXX •  ssh address: 198.168.42.1 OR www.ummspi.net •  Mapping drive: ummspipublic OR www.ummspi.netpublic
  • 9. How it compares to PirateBox/LibraryBox" http://librarybox.us Similarities with Raspberry Pi: •  provide digital content over local wireless network capability in areas •  Can connect to rechargable battery pack for backup power source •  Connect the USB storage device and the content is available to users in range of the wireless “neighborhood” Differences: •  PirateBox allows local peer to peer file sharing (read and write). •  Library Box is read only for users •  Raspberry Pi has a full Linux operating system, which allows full applications and more customization of services (e.g. Dropbox, Moodle), and user interface.
  • 10. Try it! •  Wireless UMMSPI •  It will provide an uplink, is an ethernet with that capability is plugged into the Raspberry Pi •  What do you think?
