MQTT Pager Build Is Reviving the Classic Beeper
In the digital age, where smartphones dominate communication, the humble pager, or 'beeper', has largely become a relic of the past. But one enthusiast, Kyle Tryon, is bringing back this retro technology with a modern twist. By utilizing an ESP32 microcontroller, Tryon has crafted a custom build that transforms the beeper into a useful tool for the digital age.
The ESP32's built-in WiFi and Bluetooth capabilities make it an ideal choice for this project. Tryon's code enables the device to receive alerts via MQTT, specifically notifications from the Sentry platform. This setup acts as a reliable on-call system, alerting Tryon when a system requires immediate attention. The device can play a chosen ringtone, even in the classic Nokia RTTTL format, adding a touch of nostalgia to its functionality.
The hardware setup is straightforward, thanks to the Adafruit ESP32 Reverse TFT Feather board, which includes a screen and buttons ready to use. Tryon's creative touch comes in the form of a 3D-printed translucent case, giving the device a stylish 90s beeper aesthetic. This project not only showcases Tryon's technical skills but also pays homage to a technology that has been largely forgotten.
While it may seem like a niche project, it highlights the potential for modernizing legacy technologies. As Tryon's build demonstrates, even something as simple as a beeper can be reimagined for today's needs, blending nostalgia with practicality.
