TV Lift Using linear actuators from Banggood

I always wanted to construct a TV lift, but preassembled lift kits were too expensive. These actuators were perfect and very well priced, making the project feasible-low cost. I used scrap plywood and 4 drawer guides for two stage lift. The positioning was tricky getting proper height retracted and extended. This design will accommodate my current 50 inch TV and allow for upgrade to 65 inch by repositioning the actuator lift points. I put a 50 pound weight on top to test. It worked fine-up time is a bit slower than retracting, but acceptable. Wiring proved interesting – using a 2 channel remote controlled relay reversing the polarity of second relay for retracting. I’m in the process of setting it up to work with my harmony to press one button to lift TV and turn on TV and surround sound system-then the cabinet construction.
