LED Dot Matrix Electronic Hourglass DIY Soldering Kit – 5V
Build Your Own Gravity-Sensing LED Hourglass Timer
Bring a classic concept into the digital age with this LED Dot Matrix Electronic Hourglass DIY Soldering Kit. Powered by a gravity sensor, the dot matrix display mimics real flowing sand — flip it upside down and watch the glowing "grains" cascade in real time. Whether you're a maker, hobbyist, student, or educator, this is a hands-on electronics project that's as rewarding to build as it is to display.
Made in Mainland China.
Key Features
