Circuitmess Chatter - Build and Code Your Own Encrypted Wireless Messenger Build Your Own Security-First Texting Devices! Become an engineer and learn about coding encrypted messages and private texting as you build 2 working communicators! Think walkie talks but more practical – no one talks on the phone anymore. Chatter is designed to show people that you can communicate free and remotely without the internet. It uses the so-called “LoRa” low-power wide-area network technology in order to send text messages emojis memes and GIFs. The communicators use a publicly-available set of frequencies that are allocated for use cases like this one. With these frequencies you’ll be able to send messages to the other communicator from 1 to 7 km away (depending on your surroundings). That’s over 76 football fields!
