I turned a $5 microcontroller into a travel router and it actually works

If you're into microcontrollers, you've probably heard of the ESP32. This $5 microcontroller can be easily mistaken for an Arduino with networking capabilities, but it's so much more than that. Those networking capabilities can let you access your projects remotely, sure, but they also turn the ESP32 into a networking Swiss Army knife that can do a lot of useful things for your home network.
