How can I make a (relatively) simple adjustable height desktop?
When I was working in tech support many moons ago, the office had these great adjustable desks. If you wanted to stand up while working you could raise the keyboard and monitor up to a standing height and if you got tired of standing, they would lower down. There was a motor that did the raising and lowering on those desks. I'd like to make something similar in the simplest way possible.
Bonus points if the solution can be placed on top of an existing desk and still work.
