How to build a wireless switch to control a projector lift and electric projector screen!?
This is for a home theatre setup. The projector is installed on a motorized lift that hangs in the ceiling. The screen is motorized. They are both 110v AC motors, and they both have seperate up / down leads to control the respective operation.
The screen motor is 110v 0.7 amp and the projector lift is 110v 0.8 amp. The screen takes approx. 20 seconds to lower and has no apparent calibration to stop at any particular point (I would like the controller to be able to have this capability). The lift motor has a 'up' stop and a 'down' stop adjustment that cuts power on its own when it reachs these points so the controller just has to provide power for the length of time it takes the motor to get there which is about 12 seconds.
Both devices have optional add-on hardware to make them infrared controllable but it costs approx $400 each to go that route. My hope is that I can control them with my universal remote along with having a manually controlled switch in case of remote failure.
I want to build this as my first project for contribution to Instructables and the Home Theatre community. Is this do-able for less than $50? Please help.
Thank you all for your help in advance.
