>> Just an FYI - I am mentoring a group at CalPoly that is working on an offline solar powered digital micro-library.  They will be distributing 50 of these to schools in remote pacific islands of Micronesia and Vanuatu this summer.  See attached.  It is based on Rachel & a raspberry pi clone called "Banana Pi".

>> In developing regions of the world, books are expensive to purchase and Internet- based material costly to download. As more computer devices make their way into these regions, such as low cost tablets and smartphones, a new approach is offline whereby; preloaded “micro-servers” i.e. Raspberry Pi, are providing this access to digital books and downloaded Internet content.
>> With one of these micro content servers and a few tablets, a rural school in a developing region can now have a very affordable digital library. The software and content are free to use, in most cases, but schools and teachers are asking the question: what, which is the right solution to use? This proposed project is to test four or five of these micro- server content solutions for ease of use, compatibility with specific type of devices, ease of adding new content, and supportability in developing regions.
>> The targeted short list of micro server content solutions are:
>> 1. Rachel Pi - http://www.rachel.worldpossible.org/
>> 2. WiderNet - http://www.widernet.org/
>> 3. Internet- in- a- Box - http://internet-in-a-box.org/
>> 4. Library For All - https://www.libraryforall.org/
>> 5. OuterNet - https://www.outernet.is/en/
>> 6.  http://librarybox.us/
>> 7. http://www.col.org/progServ/programmes/KM/Pages/Aptus.aspx
>> 8. http://ole.org/learning-toolkit/
>>
>> Each would be set up to test:
>> 1. Usability specific end user type devices a. Windows Laptop b. Android tablet c. Android Phone d. OLPC XO laptop e. Windows Tablet
>> 2. Power usage a. Suitability for powering with a small solar panel b. Power usage at:i. Idle ii.Normal use iii. Multiple user video streaming
>> 3. Ease of adding new content a. Web interface b. Command line c. Space management d. Videos
>>
>> I also attached an image of an solar powered laptop lab in a box.  These were used in Micronesia and the team at IIT is now working on a tablet version.
