Glad It’s working Trevor.
I’m not sure about documentation but en-file_share lets you upload files to the RACHEL device to be shared with other users.
Wikipedia for Schools is a project that was maintained by an organization called SOS Children’s Villages. I don’t think there’s much that can be done to update it unless they decide to. The alternatives are https://simple.wikipedia.org/wiki/Main_Page or the others I’ve mentioned which are still updated by WIkipedia.
To clone an SD card you’ll need to make an image of it and then flash that image to the new device. The easiest tool on windows to do it is called win32diskimager. To make an image of it you’ll have to use your mac or a device like Howard mentioned. I’m not a mac user but I think the program to make an image on them is called “Apple-Pi Baker”. Etcher is available for mac and that’s what I suggest for flashing images.
One of the options for showing/hiding content is to use the sort page in the admin interface. You can click the hide button on modules you don’t want to show to certain classes and save that.
When will you be taking this to the primary school in Bolgatanga?
