Meet Chatter 2.0

Build private communication devices

Assemble a pair of DIY wireless communicators that let you send text messages without Wi-Fi or cellular networks. Build them yourself and discover the power of LoRa technology.

Secure line, no network needed

Chatter uses LoRa, a long-range, low-power radio technology, to communicate directly between devices. Your messages will be encrypted, even off-grid.

Learn about wireless communication

Go beyond just using wireless devices – understand how they work! Building Chatter teaches you about radio communication, signal processing, and electronics.

Program beyond basic texting

Dive deeper into coding! Draw and write on the screen, learn how to make buzzing sounds, and much more.
