DIY LED Hourglass Electronic Soldering Kit – 57 Blue LEDs, 5V Microcontroller

Build your own mesmerizing LED hourglass with this hands-on DIY electronics kit! Designed for students, hobbyists, and electronics enthusiasts, this soldering practice kit lets you assemble a fully functional electronic hourglass that mimics the graceful flow of sand — using 57 bright blue LEDs controlled by a microcontroller. It's the perfect project to sharpen your soldering skills, deepen your understanding of circuit design, and end up with a cool decorative piece when you're done.

Please Note: This kit is intended for individuals with basic circuit assembly experience. Detailed assembly instructions, circuit diagrams, and working principle documentation are included. Assembly success depends on the builder's skill level — please review the product description carefully before purchasing.

Made in Mainland China.

How It Works

The electronic hourglass uses LEDs to simulate sand particles. The illuminated LEDs on the upper half "fall" one by one to the lower half, just like real sand in an hourglass. Once all LEDs have shifted to the bottom, simply press the restart switch and the cycle begins again. A built-in micro switch lets you adjust the speed of the hourglass — slow and meditative or quick and exciting, the choice is yours!

Frequently Asked Questions

Q: Do I need prior soldering experience to assemble this DIY LED hourglass kit?

A: Some basic soldering and circuit assembly experience is recommended. The kit includes detailed assembly instructions, circuit diagrams, and working principle documentation to guide you through the build. Complete beginners may find it challenging, so we suggest practicing basic soldering on a simpler kit first.

Q: What power source does the 5V LED hourglass kit require?

A: The kit operates on a 5V DC power supply. This is compatible with standard USB power adapters, making it easy and convenient to power once assembled.

Q: Can the speed of the LED hourglass be adjusted?

A: Yes! There is a built-in micro switch on the PCB board that allows you to adjust the flow speed of the LED "sand particles," so you can customize the hourglass cycle to your preference.

Q: Can this kit be used as a decorative light when not running the hourglass animation?

A: Absolutely. When 28 LEDs are simultaneously illuminated, the assembled kit doubles as a soft ambient night light — making it both a functional project and a decorative display piece.
