Andy Morris has solved an aggravating problem. You can get a remote control for tower fans, but they’re too noisy for the bedroom. Propeller fans are nice and quiet, but they don’t come with remotes. So Andy devised a propeller fan remote control that does not require line-of-sight, which makes it easier to use in the dark.
The gadget comes with off/on, three fan speeds, and multicolored LEDs to indicate the fan’s speed. As a bonus, it beeps to indicate that the fan got your message.
The design is well thought out and I have no doubt the gadget works as described, but it's a lot of labor to build. There are cheap commercial radio-controlled (300 MHz) appliance switches on the market that would at least turn the fan on and off. There are also 3-speed models using phase angle controllers for ceiling fans. I have one that cost <$20 and works just fine. There's no reason it wouldn't control a table fan just as well. All one would have to do is install it in a suitable box.
I also like to build stuff but generally do so when there is no economical solution already available.
