c4tp's friend asks: "Recently my Mother informed me that my grandmother's 80th birthday is approaching. She suffers from glaucoma and it is rather hard to read small text for her. The consensus with our family is to buy her a video magnification device, but the ones I found online were at the minimum of $500 (US), a bit steep for me (and my family). So what I am asking basically, is there a way to build/assemble the parts these retail devices use for a cheaper price?"
Computers are unreliable, but humans are even more unreliable.
Any system which depends on human reliability is unreliable.
