Being a hacker, I naturally gravitate to junkyards, yard sales, and surplus warehouses. In addition, pursuing our local newspaper’s classified ads, Craig’s List, and Ebay often uncovers really neat items that can be turned into IoT projects. Case in point, a couple of years ago I was on Craig’s List when I ran across this ad:
So of course I picked it up and brought it home. Since we have a hard time getting our youngest out of bed in the morning, I made sense to try and hook it up to his bed.
The first order of business was to understand how the bed’s controller works. We first thought that the controller used PWM so we hooked up our Oscilloscope to the two metal wires that travel from the controller to the bed’s screw drive. We moved the controller up and down but no signal was being recorded. Sonoma then noticed that the “wire” was a hollow tube. Taking a wild guess, we blew down the pipe. Sure enough, that made the bed move.
