This DIY standing desk controller supplies luxurious car-style reminiscence settings

Among the finest options you’ll discover on a flowery luxurious automotive is seat place reminiscence. Sometimes, there are at the least two profiles that “save” the place of the seat. When switching drivers, the brand new seat occupant can merely push the button for his or her profile and the seat will robotically transfer to their saved place. Uninterested in adjusting it manually, Andy of Yeah Nah DIY applied an analogous reminiscence perform into the controller he constructed for his standing desk.

There are quite a lot of motorized, adjustable standing desks available on the market and a few of them do have reminiscence settings. However the mannequin Andy owns didn’t have the performance. As a substitute, it simply had two buttons to lift or decrease the desk. His DIY controller solves that downside, making the desk way more handy to make use of from each day.

The unique controller was quite simple, with two buttons to activate the motor (one with reversed polarity). Fundamental restrict switches disconnected energy to stop collisions.

The brand new controller, managed by an Arduino Nano Each board on a customized PCB, has comparable buttons, but in addition three reminiscence positions. To search out these positions, the Arduino must know the way excessive the desk is at any given time. Andy added an encoder to the elevation screw to rely revolutions, that are then used to calculate distance and subsequently peak. With that suggestions the Arduino controls energy to the desk’s motors by way of relays and likewise screens the restrict switches.

The Arduino and customized PCB match into a pleasant, minimalist enclosure that mounts onto the entrance of the desk inside straightforward attain. The entire 3D fashions and the Arduino sketch file can be found for obtain when you have an analogous desk and wish to improve it in the identical method.
