The follow-up to the original Chatter is here! These easy to assemble, encrypted LoRa communicators are not only useful for their headline feature but also allow writing custom firmware and games. The pair of communicators comes pre-soldered, so all you need to do is assemble the housing around the completed board.
My brother and I each assembled one, and while there were some tricky steps (keeping the battery cable out of the way while trying to close the case), overall it was easy and could definitely be accomplished by young hackers with a little supervision and encouragement. For some reason my NiMh batteries didn’t quite fit the holder properly, though I’ve had this happen with other devices as I think the bump on the positive end of the battery isn’t as long as most alkaline batteries.
Powering the device from USB-C worked flawlessly for testing, and once the included lanyard was attached, we were able to get each other set up as friends and send a few messages! Typing out longer messages on the phone-style keypad could be improved by using a system like T9, but even so it works well, and knowing the unit doesn’t require any infrastructure like WiFi or LTE is super cool.
The other neat facet of this device is its programmability. Just like the original Chatter, you can program the device using CircuitBlocks or the Arduino environment. It’s a great way to explore and learn about wireless communication – especially LoRa, the long-range, low-power radio protocol used in the Chatter 2.0.
CircuitMess are so sure you’ll like the new Chatter 2.0 that they’ve offered a generous 35% off promo code – SECRET35OFF – that’s valid until December 5th, 2025! So if you need a gift for a hacker or teen who is interested in STEM, cryptography, wireless communication or programming, the Chatter 2.0 is bound to be a hit.
