~19 years ago my first real introduction to software/hardware/firmware hacking and electronics/soldering was turning the digital, one-time use "disposable" cameras that CVS etc. sold, into reusable digital cameras. Plenty of issues along the way and drawbacks with the final product, but for the time it was one of the cheapest digital cameras you could get (because the price was heavily subsidized on the fact that you would be returning it to develop the pictures, at which point it could be cleared and sold again). That definitely helped put me on the tinkering path I'm on now.
