Product Description

A flashing experiment box for electronics enthusiasts

DIY is not only a practice of technology but also a redefinition of life aesthetics.

Connect logic and imagination with your hands, and awaken the original joy of creation in soldering and coding.

A hands-on DIY kit built for electronics enthusiasts: assemble the fun running-light circuit by soldering, easily get started with electronics fundamentals and ignite innovation in practice.

Circuit function introduction

this circuit uses NE555 + CD4017 chips, is powered by two CR1220 button cells, and has 7 LEDs flashing in a loop. 

It shows the function of the CD4017 chip very intuitively. 

The small aircraft shape is both fun and practical, making it very suitable for electronics enthusiasts and students.

Product Display

During installation, be careful not to block the battery compartment: solder the battery spring clip first, insert the battery, and then solder the remaining components. 

Solder the long leg of LED7 to the positive (+) pad of board B and the short leg to the negative (-); when assembling the two boards, + is on the LED5 side.
