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 …
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
What about lack of available techies?
• Just plug it in … or unplug it when done• Wireless network name: YOERBPI• Server name: www.yoerbpi.net• If you want to be a “techie”
• User name: pi• Password: <……….>• ssh address: 198.168.42.1 OR www.yoerbpi.net
How it compares to “other” things i.e. Librarybox, egranary, Rachel, GLOWM
Similarities with YoerPI:• 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 YoerPi can be configured
to be either read-only or read-write
• YoerPi content is easily modified, non-techie can add/delete/modify content
• YoerPi 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 College
• Kenya–Bishop Lawi Imathiu Secondary School–School of Public Health (University of
Nairobi)
• Ghana• Malawi• Liberia
Try it!• Wireless UMMSPI

• It will provide an uplink, if an ethernet with that capability is plugged into the Raspberry Pi
