The main video call control panel is made up of PCB

[memestra] is a teacher whose life has become a video conference series in the past year or so. With all classes and meetings, they spend the whole day switching between Zoom, Teams, or Meet. If anyone needs one piece of hardware to control them all, it’s [memestra]. Well, and all the other teachers out there.

The hardware – an Arduino Pro Micro and a few buttons – shouldn’t come as a surprise, except maybe [memstra]the use of a network of resistors for the LEDs. Still, there’s a lot to love about this little box, starting with the speaker. This is not milled or laser cut metal – each side is a PCB, and they are all soldered together in a box.

We especially like the top panel, which fits over the PCB where all the components are soldered. Each of the non-volume buttons has several functions that can be accessed by pressing, long-pressing, or double-pressing. But even the volume buttons have a dual function: pressing them together to mute and unmute the sound. Yes [memestra] never forget which button does what and how, there is a handy reference board silkscreened on the bottom panel.

Like a real teacher, [memestra] wrote full instructions for anyone looking to build a similar device. The heavily commented code should make it easy to insert keyboard shortcuts for Discord or whatever else you might use, although it should be noted that this box is optimized for desktop apps and not browser-based versions.

Are you just looking for a fun way to end video calls? Pull chains are pretty fun.
