I know I'm always here with one project after another, but they get done.
So now I'm working on remote controlled blinds. I have moved to a loft and it has huge windows on one side and the bedroom wall doesn't go all the way to the roof. I like the open concept but I don't want to go turn all three blinds closed every night and open every morning, plus automatic ones would be slick. I have the motorization figured out, it's just a gear motor with a limit switch and an H-bridge connected to a latch. What I need is a remote.
Originally I was going to build a transmitter, but that really seems more trouble than it's worth, it basically just needs to transmit two states, up and down. I don't think it's worth the time to build a radio transmitter for that, also a store bought one would probably look better. Can you guys suggest one to buy? I want radio because I may not have line of sight, though at most I will be 15 meters away and through one partial wall. And I only need to send two signals. I am fine with something that needs modifications. I was just drawing up a way to do it with an OOK radio module and started noticing that for the $20 doing it myself will save me (at most) it's just not worth it. I have google searched but all the cheap pre-made remotes I find are already set up to go to an AC relay or a TV, and those ones are IR. There are cool keychain garage door opener controls that would be great, but I'm not sure how hard it might be to make a receiver for that. It could plug into a wall on the end with the blinds, if that helps, but since I don't want to plug in the controller a powerline control system probably isn't the best option. You guys always have some good practical ideas.
Something like this but with a way to connect it to an electronic project would be perfect
