And maybe the answer is to simply buy garage door opener controllers and re-purpose them, but I bet someone here has a more elegant solution. Many of the things I want to make for my house tend to require behavior like an automatic garage door; meaning that the push of a button would open or close, lift or lower something, then stop in the open/closed, lifted/lowered position, and do the same in reverse when the button is again pushed. Most of the things I would do are for in the house, like opening and closing large shade louvers, lifting a panel to expose a TV (or lift the TV itself, yow!), etc. These things don't need the safety functions or the torque I imaging you need for a garage door but the functionality would be essentially the same. So the question is, are there off the shelf controllers for things like this? I haven't been able to find such a thing online but then I'm not sure what to call it. The next question will undoubtedly be sizing the right motor for the job, or what the best assembly is for the specific task, but I'll save that for subsequent posts if anyone here has ideas for me. Thanks in advance.
