There is a special type of Jewish nerd who looks at electronic devices approved for Shabbat and thinks, gosh, I really wish I knew how the electronic circuit inside this works so that the rabbis were able to approve its use on Shabbat. Luckily, that nerd now has a place to visit, in Alon Shvut at the Zomet Institute’s Zomet Experience visitors' center. Zomet created a hands-on science center for children and adults to understand the engineering behind things like metal detectors, voice amplification systems, oxygen tanks, keyboards, lights, hospital food heating trays, and electric wheelchairs that are kosher for use on Shabbat.
