I'm building a survival computer with all of my survival books in .pdf, including things like wild edibles, trapping, repairing small engines, permaculture, gardening, wilderness survival, home construction, and much more. It is going to be about the size of a book, 7" x 5" x 2.5", have a solar panel on the back, powered off of 4 rechargeable AA or AAA batteries, and a built in keyboard, mouse, and touchscreen. The solar circuit is going to be able to charge AA or AAA batteries so that I can use them for a flashlight as well as to power the computer. I am building a fiberglass case that has a clear plastic cover to water proof the whole thing. It uses micro-SD cards that can be switched out for more space and I'm going to include a ton of survival and informative videos, pictures, and even a few hundred games to pass the time. I may build an LED light into it. I'll also shock-proof it as well using rubber grommets to mount the computer board on. If you have any other ideas I'd love to hear them. Do you think it's a good idea?
