Many on old analog board used DIP switches for setting amplifier gains.
"There was a time when you could change some equipment with DIP switches either legit from the outside, and sometimes less legit if you got inside and found the DIP that set configuration. I once had a setup to measure velocity of projectiles using two optical sensors spaced a known distance apart. You could change the range of the time and the units it reported in via a DIP switch."
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
