Meshtastic is a tiny gadget that lets you text your friends when there’s no Wi-Fi or cell signal. You pair it with your phone and text through an app just like always. The clever trick is that if your friend is too far away, your message hops through other people’s Meshtastic gadgets to reach them, like passing a note through a chain of friends. People use it for hiking, camping, festivals, and emergencies, and it can show where your friends are on a map. The only catch is that it only sends short messages, not pictures or calls, but it works almost anywhere. Be sure to bring your tablet or laptop. This class is free for all Veterans and ACTIVE duty Military.
