this reminds me of something I built pre-LLMs that i called a "doomsday computer"
it was a raspi with a couple 18650s and bms taken from a drill battery combined with a pico-projector and a laser keyboard stuffed in a waterproof acrylic cube with a stack of sd cards filled with stuff like the survivor library and an offline copy of wikipedia.
complete with fold out solar panels and circuitry taken from one of those amazon solar phone chargers.
worked well for a few hours at a time at night while camping. eventually i was planning to add a retropi sd and a best of music sd (like classical and the rolling stone magazine top 500)
