At its heart is an Arduino UNO, which syncs the RGB LED ‘bubbles’ and a servo-driven aiming arm to the game’s real-time data.

A light direction sensor, SAR ADC, and energy harvesting photodiodes are integrated on a single chip based fabricated in a 0.18 µm process. No external power supply is needed for the chip to operate.

Pretty much every project I've done just lately has required me to test out some servos and experiment with their positions before they go into the assembly. I usually make a quick servo tester on ...

Thus, they entered a heart rate sensor to our 2025 One Hertz Challenge! The build is based around a Wemos D1 mini, a ESP8266 development board.

A research team at Los Alamos National Laboratory recently found that the strength difference between two very high-frequency radio pulses in lightning is closely related to the altitude of the ...
