Desk with automatic height adjustment

Arduino / Tables and chairs

Added 6 comments

The master spied the idea of such a table in one well-known chain store. True, the drives there were in the legs of the table and the lifting height is smaller, but the principle is the same. To make a table, the master-master needed the following

Materials and tools:
-Laminated board: 1200 x 600 x 18 mm-1 pc; 1200 x 405 x 18 mm-1 pc; 1200 x 300 x 18 mm-2 pc;
- Steel brackets: 50 x 50 x 50 x 5 mm-2 pcs; 50 x 50 x 20 x 5 mm-8 pcs;
-Screws;
- Guides 350 mm-4 pcs;
-Linear electric drive;
- Power button -2 pcs;
-Installation box;
-4-core cable;
- Power supply 12V 1A;
- power board Arduino Nano;
-Extension;
-Driver stepper motor;
-Arduino Nano;
-Sandpaper;
-Varnish;
-Cable ties;
-Cable channel;
-Drill;
-Crown on wood;
-Screwdriver;
-Painting brush;
-Soldering iron;
- staples;
-Nippers;
-Insulating tape;

Step One: Project
According to the project table consists of two parts. The lower part of the leg with a crossbeam, the upper part of the leg with a table top. Between the upper and lower legs are installed guides. A linear electric drive is fixed in the center of the crossbar.

Step Two: Cropping
Cuts panels to the desired size.

Step Three: Sanding and Painting
On the panel, the master decided to apply a darker coating. Sanded the surface. Painted and varnished the surface of the panels.

Step Four: Guides
Marks up and sets guides.

Screws on the brackets.

Step Five: Crossbar and Cover
Screws the crossbar and cover.

Installs a cable channel into the table cover.

Step Six: Linear Drive
Installs a linear actuator.

Seventh step: control buttons
In the mounting box, drills two holes for the buttons. and one for the wire. Installs buttons, mounts wires. Secures the mounting box to the table.

Step Eight: Arduino Nano
In principle, you can do without the Arduino Nano, but the master wanted to set up different modes of raising and lowering the countertops. The master printed the box for the Arduino Nano, the power supply module, and the stepper motor driver on a 3D printer. Loads the code and mounts the entire electronics.

Fixes everything on the table. Connects the drive.

The table is ready.

How it works, you can watch the video.

Hello! Thanks for your comment, I mentioned both of these points in the instructional. Two actuators would improve stability, although this increases the cost (bending in the drives will still lead to instability). No, you don’t need an arduino, although I turned it on for the “double-click” function, and also to open the door for possible additional functions

So what are they all

different modes of raising and lowering the countertops

?
After all, this is the meaning of a certain "automation"?

You sit on a chair, a bunch of sensors determines your height, calculation is in progress and the table rises to the desired height.

Use your finger to press the button and automatically adjust it))) Don’t find fault with Ivan. You need to somehow make it clear that the adjustment is not jerking up with your hands, but on the drive.

And what is the "automatic adjustment"? How is it produced?
