Project Update

 

I was having so much fun playing with the Beaglebone Black and TI SensorTag that I almost forgot to write this update!

 

Anyway, got some sliders to mount the screen to and made a (rather bulky, but strong) frame to mount to the desk and hold everything in place. The next step will be to add the stepper motors and limit switches to automate the lift. My 3D printer is still acting up, so I'll probably end up making the piece manually. Don't worry, I have a plan ...

 

Here's a short video showing some assembly stages and testing the sliders manually.

    You might try a counter weight? As the screen rises a weight on a string falls. You could use plumbing pipe so that the weight does not bash into anything and a pulley mounted just under the desk.

    Initial testing shows the weight is (luckily) not a problem, the steppers can handle it

    Yes! With only a few weeks left, everything has to start coming together. As for IKEA selling these, well, the sliders are from IKEA also, so they do already have most of the parts

    Happy to read this Frederick.

    If I remember you showed in one of your first posts you tested the monitor sliding with a pair of steppers that seemed to be able to lift then entire table image

    The idea of the counter weights was to take in account but it is not very elegant in my opinion ...

    It is a good idea ....

    I still like the automotive electric window mechanism ... and no there isn't room in the suitcase.
