Read More…Spectrum One is a desk-based WiFi activity monitor built around the ESP32 and a custom-designed PCB. It scans nearby 2.4 GHz traffic and visualises signal intensity in real time using a 10-segment LED bar and a 16×2 LCD display.
This started as a personal experiment to make the invisible wireless environment visible in physical form. Instead of checking apps or software tools, Spectrum One gives you a continuous visual reference directly on your desk.
Each unit is assembled and tested by hand. The design is fully documented and released as open hardware, and the firmware source is publicly available. It’s a compact, purpose-built device for anyone curious about the wireless activity around them — built properly, not mass-produced.
