2. Common Challenges to Digital Learning in Developing Countries High technology cost Limited technology availability (equipment, understaffed dept.) Unpredictable infrastructure

3. The “last mile” on the Internet is often challenging …

4. 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 for less than $200 …

5. Hardware - Raspberry Pi and accessories An ARM GNU/Linux box (Model B): ……………… $35 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

6. You can use any micro-USB power source: rechargeable battery, laptop, or wall chargers. If you use one of the rechargeable batteries shown, it can act as an uninterruptible power supply.

7. What about lack of available techies? Just plug it in … or unplug it when done Wireless network name: YOERBPI Server name: www.yoerbpi.netwww.yoerbpi.net If you want to be a “techie” User name: pi Password: ssh address: 198.168.42.1 OR www.yoerbpi.net www.yoerbpi.net

8. How it compares to “other” things i.e. Librarybox, egranary, Rachel, GLOWMLibraryboxegranaryRachelGLOWM Similarities with YOER 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: Others are read only for users, while YOER Pi can be configured to be either read-only or read-write YOER Pi content is easily modified, non-techie can add/delete/modify content YOER Pi has a full Linux operating system, which allows full applications and more customization of services (e.g. Dropbox, Moodle), and user interface. The pre-packaged content either has copyright or technical restrictions that limit adaptation.

If you happen to be in Africa … Ethiopia –St. Paul Hospital Millennium Medical CollegeSt. Paul Hospital Millennium Medical College Kenya –Bishop Lawi Imathiu Secondary SchoolBishop Lawi Imathiu Secondary School –School of Public Health (University of Nairobi)School of Public Health Ghana Malawi Liberia

10. Try it! Wireless UMMSPI http://www.yoerbpi.net/rasppi/ http://www.yoerbpi.net/histology/ http://www.yoerbpi.net/eyes/ It will provide an uplink, if an ethernet with that capability is plugged into the Raspberry Pi What do you think? https://wiki.umms.med.umich.edu/display/ET/Raspberry+Pi
