/diy/ - Do It Yourself

>>174

Interesting vid. I found another one which shows how they do it. Looks like an electric motor drives a pair of screws which raise and lower the middle section via a captive nut.

A bit difficult to diy (at least for me) she to the specialised parts.

Before I checked the vid I was thinking about a way to do this with the raising drawer almost at the point of balance with a bucket containing weights and bulge pump under the table. You then pump a little water into the bucket using 12v pond pump. The bucket pulls up the TV drawer. To lower TV, pump water out of bucket using bilge pump.

Would be relatively simple and easy, but the water would get nasty after a while.

Get an arduino, a stepper motor, a stepper driver, hook them up, attach screen to two slides (you could probably just use ones from drawers but it depends on the design), attach stepper to a leadscrew, make the leadscrew nut move the compartment holding the screen. Adding a counterweight will enable you to buy a smaller stepper motor. This much, ignoring cost of the screen and the table itself, should cost somewhere around $30-$50.

protip: sewing machine cabinets have a similar feature and do it pretty simply.

That is a cool protip. Nice work maker.
