Thread: LCD lifter parts?

I would suggest using a worm gear setup or a pulley system, With the pulley system providing the setup is clean and well measured it should easily drop using the weight of the LCD. Using stepper motors and a stepper control will allow you to have proper control over the lifting system.

There are a few options in which you can use this, I guess most would depend on how much room you have beside,front,below and behind the using itself.

I would personally use a scissor lifter which would be a single motor lifting the LCD from below with a contracting scissor that will expand/close the two rodes with a swivel mounted top plate. But having something flush and molded would be nice a clean..

Are you open to other options?

I have no room under the lcd, i have some room behind and front of the LCD.

Is my lego idea bad?

If your to go with that method, I would use dual shafts.. center single one would be prone to jamming.

Yes would use dual shafts, i have only one in my lego collection...

But where can buy real parts? cant make it with lego

i have no idea where you can get parts to make that-- time for you to wander through a hardware store..

You could use an old CDROM tray mechanism depending on the space available. A sliding balast can be used to zero the weight similar to how an elevator works, or springs but it would have to work harder at the ends.

I love projects like this :-)



Very much like the lego, I guess. And the sissor suggestion.

If you lade (svarvar) of the threads at the end of the screw you can make it turn nicely in the U-beams that at the same time is the track for the LCD.

If you also lade (is that the proper word really?) the screw at end positions the movement will automatically stop there.

A simple rubberbelt will also be a protection against jammed mechanics, so a simple DC motor will do.

You can place the motor in front where you have room.

The hinges can be very simple things. Attach a second nut on top of the ones on the screw. If that is done properly it will also keep the nut on the screw from rotating.

Note that the screw will have to be halfway right threaded and halfway left threaded. Maybe a more practical solutions is two screws. Then you will get more lift too.

just to make it more complicated lol pneumatics
