Wow, this is excellent. I love it. I’m just a bit confused on how the string will work to lift the upper part down. Do you have any documents or clarification on that?
This is an awesome project! Really well documented and done. The only thing I'd have changed is leaving gaps between the slats, and then potentially allowing the TV to create a glow effect from behind them (perhaps with a layer of semi-opaque plexiglass).
Thank you! I toyed with the idea in one of the designs (at 2:01), but I wasn't sure about the structural strength and it might have been a bit too see-through.
Curious if maybe bike chains and gears with adjustable mounting can be used for the moving cover to reduce the growing gap from paracord. Thank you for sharing the awesome build, that's a very nice TV lift cabinet!!
Thanks! Bike chain is a bit messy with the grease, but I think switching to a non-stretch cord would have helped too. Adjustability was definitely key.
Thanks! Besides cutting the plywood pieces to size, almost everything else was done in the apartment. I actually 3d printed a fan duct to properly ventilate the room for wood sanding/finishing... a bit of yak shaving in this project.
Having a TV placed at a normal height for an average seating person seems logical but exceptionally rare! I liked the clever box in the box moving in the opposite direction to the TV-set but wouldn't it be simpler to use separate linear actuators for the box instead of pulleys? Also, plywood is not the best material for designer cabinetry. Try bamboo board!
Fantastic result, from concept, fastidious design to implementation, well done. You could have put a small lip around the top panel to deal with hiding the gap as well as adding rigidity. An led strip could have also been hidden there to provide a cool ambient glow! Also i will add a switch that will turn on the TV as it raises and turns off the TV when it closes to save energy by not being on standby. I also want to figure a way of operating it via an Alexa command. I have lots of ideas, its just implementing them that takes time and effort! A very interesting, informative and inspiring video.
Thanks, happy to share but the cut list is more of an intermediate doc. It's far from being a build plan. Shoot me an email - david (at) dcliu (dot) com - and I'll send it to you.
I recommend looking for a linear actuator, which will usually have a rated load. The one I used lifts 155 lbs. My TV is 55 lbs, plus the top lid and speaker, minus the counterweight of the moving cover. Designing your own actuator is of course possible but I don't have experience with that.
