What is a “Raspberry Pi”? Wikipedia tells us: “ The Raspberry Pi is a series of credit card–sized single- board computers developed in the United Kingdom by the Raspberry Pi Foundation with the intention of promoting the teaching of basic computer science in schools and developing countries.”credit cardsingle- board computers Raspberry Pi Foundationcomputer science Elinux.org tells us: Conceived 2006 Eben, Rob Mullins, Jack Lang & Alan Mycroft 2011, first Alpha boards powered up and booted 2012, manufacture and shipping of first model “B” boards 2015, “Pi 2” boards shipping, Windows IoT available for Pi

Why build such a device? “The idea behind a tiny and affordable computer for kids came in 2006, when Eben Upton, Rob Mullins, Jack Lang and Alan Mycroft, based at the University of Cambridge’s Computer Laboratory, became concerned about the year-on-year decline in the numbers and skills levels of the A Level students applying to read Computer Science.” Faculty concern with decline in Science, Technology, Engineering and Math (STEM) (

What else can you do? Yoer Pi A portable, adaptable local area network even in restricted Internet and power

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

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

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 & 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

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.

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

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.

Try it! Wireless UMMSPI SSID = YOERPI It will provide an uplink, if an ethernet with that capability is plugged into the Raspberry Pi What do you think?
