If you have your modem and router squirreled somewhere behind furniture (or even within rack case), you know how problematic reboots are. They always involve blindly going in the nest of wires trying to either get device outside or unplug it hoping you’ll be able to plug it back again. For such cases it would be awesome to have a reset button mounted somewhere reachable.
Functionality is as follows. Press the button for a second or two (until LED light goes dim) and upon releasing it, you will see LED blink. During that time your device is without power. Power comes back after about 4 seconds with your device happily rebooted.
This box takes any 9-60 V input and has two outputs just in case you have multiple devices you want to control. As there is no voltage control, beware not to connect different voltage devices together.
