This is a smaller version of a design I posted a few years ago, this time it’s for a single HDMI-based device. It allows you to switch between several devices without having to go behind the TV.
If you’re juggling a bunch of devices this would be extremely handy. Nowadays there are many plug-and-play consoles, clone consoles, video game dongles (from AtGames and Arcade 1UP), streaming devices, single board computers, and soon: gaming handhelds with HDMI output (the upcoming Analogue Pocket). Almost all of these are powered by USB too.
Most of these devices would benefit from a power switch, especially those game dongles which stay powered-on until unplugged (seen in the example below). So I included a humorous kill switch for the robot:
The robot’s body moves like a lever, so powering off this device makes it appear as though you are also deactivating the robot. The arms are loose and swivel freely, the LED eyes indicate power.
