The Tech Report have an interesting project for those interested in building their own electronic gadgets and doohickeys. They have created a project which uses a NodeMCU open source microcontroller for IoT devices to allow you to remotely power cycle your PC via an RF signal. The build will teach you about creating your own IoT device, a bit about how to secure said device and insight into the signals which tell your PC to power on or off or to go into sleep mode. For those already familiar with the components and processes utilized by this project, it is a quick and easy way to design a device that retails for $25, for a lot cheaper. Take a peek here.
"Commercially-available remote power switches make turning a PC on and off from a distance a simple task, but our resident microcontroller enthusiast thought of a few ways such a product might be improved. Join us as we see whether those ideas could be implemented for about $10 in parts."
