There are Ceiling Fans with a remote control. Would you be able to build a secondary wall mounted control (clone maybe) so that you could keep the hand remote by the bed side and the Ben Heck made one on the wall.
The one I've looked up is Hunter model 99122
Here a link to all the schematics, internal photos, diagram: https://fccid.io/IN2TX41
This would be a great opportunity to Use an oscilloscope and reverse engineer something!
Thanks for your consideration.
Reason for build: there are times when you walk in at night and cant find the remote. Light only turns on with remote if it was previously turned off with remote. You can't just go and pull on the light chain, because it wont work unless you first use the remote.
