I am trying to build a device that will slide the Bookcase Open and Closed to reveal the Batpoles in a 1:12 Scale.
It is plastic and measures 10” Tall x 5” Wide. It is basically a Dollhouse Sized Sliding Door.
Is there such a device that already exists or can someone here in the forum help with this.
It is a plastic bookcase that would need to simply slide back and forth.
Thanks in advance for any and all help!

 

BTW… This Little Plastic Panel that needs to slide open and closed is about 10” tall by 5” wide.
Thanks again in advance for any and all help.

 

Welcome to AAC.

There are numerous ways to achieve the motion. Since the door is 5" wide I'll assume you want to slide it approximately 5" in either direction. To move a door you're going to have to take a mechanical approach. You could do it with a micro-motor and some pulleys, but then you have to hide the motor somewhere and have strings running through your project. If you're far more mechanically minded you could try and build a linear motor to sit above the door. As you energize certain sections of the motor your door will jerk from one position to another like the second hand on a battery powered clock. So that approach doesn't seem like a very realistic approach. A third approach would be to have a screw drive and a hidden motor to turn the screw. That way you can screw the door open or closed. You first need to decide what approach best suits your application.

 

I can definitely hide the motor (which I assume could be pretty small) as well as hide any strings too.
Can you give me any Amazon Links (or similar) to what exactly try I would need?
Thanks again for all the help and greetings from New Orleans!

 

I found this which looks like a possible place to start but how would I reverse the direction to close the door?

Here's a drawing I made back in December. It was concerning limiting the motion of a sled to one point or another with being able to stop in any position between fully one way or fully the other way. For what you're asking, a simple DPDT Switch such as S1 shown in the "Simple DC Motor Reversing" diagrams. The problem with THAT solution is that the motor will want to keep running. That's the reason for the MPB1 (Momentary Push Button) Normal open Push Button. S1 sets the direction and MPB1 runs the motor as long as you press and hold the button. In your project it won't be necessary to wire in limit switches.

 

Did you watch the video with that motor? It IS a gear reduction motor but it still spins quite fast. You'd want a much smaller pulley to pull your strings and probably not run it at its full rated voltage. I imagine the door opening and closing slowly. That motor in its current configuration will slam the door open and closed. You won't want that.

 

Tony.... Thanks so much for the Diagram.

I would like it to open and close at a fairly slow rate.

I need a Parts Shopping List Including the motor, the diodes and the switches, and the Gears/pulley needed.

I am a hobbyist so the more information for me the better.

Was in inspection over 40 years. Electronics mostly. Now I'm a cabinet maker.

Can't help you. I could - but then you're just building what someone else said. You have the basics. Motor speed, gear ratio, pulley sizes, those are up to you. I don't think you're going to need limit switches. You might even find a DPDT switch with Momentary Center Off. Flip it one way and the door opens. Release the switch and it stops. Flip it the other way and it closes. Release it - - - . You get the idea.

Just did a quick search on Amazon. Found this page. From here you should be able to choose what best suits your project.
