Maybe it’s because I grew up in the early 90s, in a time right before cell phones and eventually smart phones became ubiquitous overnight, but there’s something so nostalgic and awesome about a walkie-talkie. The mere thought of it makes me want to play an OTT game of capture the flag. Very cool project from Chris Greening up on Hackster.io.
It’s a Walkie-Talkie based around the ESP32. It transmits audio using either UDP Broadcast or ESP-NOW.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
