I'm not even sure this is the right section for this, but I think it's close. I've been looking online for solutions to hide my projector that don't include me spending $1500. I was curious if anyone has made their own motorized tray system to lower and raise their projector? If so, some pictures or advice on the subject would be very helpful. Even a point in the right direction would be nice; as I'm pretty much starting from scratch.
