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! Chatter can communicate free and remotely without the internet almost like old-fashioned walkie talkies. 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. 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! Chatter also includes several other fun functions, including a friends list, chat color customization, profile avatars and notifications. Plus, the friend pairing allows you to connect with more than one other Chatter device.

Assembly time of 4 hours, medium difficulty. FCC Compliant. For ages 11+.
