MiOYOOW Sound-Activated LED Glasses Soldering Kit - DIY STEM Project for Learning Electronics

The MiOYOOW Sound-Activated LED Glasses Soldering Kit is a DIY electronics project that lets you build your own light-up glasses that flash in response to sound or music. This soldering practice kit includes two 12V batteries, adjustable sensitivity, and a circuit board with mesh holes for visibility. Designed for school learning and party fun, it helps develop soldering skills and basic electronic knowledge.

How the Sound Activation Works

The kit uses a microphone to pick up sound, which is amplified by a transistor and sent to a KA2284 level indicator chip. This chip drives five groups of LEDs: the louder the sound, the more LEDs light up. A sensitivity adjustment knob lets you control how responsive the glasses are to ambient noise. When rotated left, sensitivity decreases; rotated right, it increases.

What You Get in the Kit

• LED glasses frame (to be assembled)
• Circuit board with pre-soldered components
• 2 included 12V batteries (type 24A)
• Through-hole soldering components for assembly
• User manual available for download

Who Is This Soldering Project For?

This kit is ideal for students, hobbyists, and anyone learning to solder. It requires basic theoretical knowledge and some soldering experience—not recommended for complete beginners. Schools use it to teach mechanical assembly and electronic principles. The finished glasses work great as a party accessory for concerts, raves, or festivals.

Assembly Notes

Before starting, download the illustrated manual from the Amazon product page. The board has clear labels and through-hole pads for easy soldering. LEDs are mounted on the outer side so they shine away from your eyes, causing no visual interference. The mesh holes in the board allow you to see through the glasses when worn. Remove batteries when not in use to save power.

Frequently Asked Questions

Does the kit include batteries?

Yes, it comes with two 12V 24A batteries. You can disassemble and replace them later.

Do I need soldering experience?

Basic soldering skills and electronic knowledge are required. The kit is a practice project, not a beginner-first build.

How do I adjust sensitivity?

Use the button on the board. Rotate left to lower sensitivity, right to increase it. If the glasses don't respond to sound, try adjusting this.

Will the LEDs hurt my eyes?

No. The LEDs are positioned to shine outward, away from your eyes, and the circuit board has mesh holes for outward visibility.
