Perfect for Beginner Soldering Practice: Easy-to-follow instructions and clearly marked PCB (Printed Circuit Board) make this kit ideal for students, hobbyists, or anyone learning how to solder. Practice your through-hole soldering skills without the risk of ruining expensive equipment.

Fun & Functional – It Actually Spins: Unlike boring practice boards, this kit transforms into a fully functional, high-speed fidget spinner once assembled. The unique 3-arm design fits perfectly in your hand, providing a satisfying spin while showing off your soldering work.

Mesmerizing LED Light Show: Features 11 bright, flashing red/blue LEDs that activate when spinning. The persistence of vision (POV) effect creates stunning circular light patterns in the dark, making it a cool gadget for your desk.

STEM & Educational Gift: Combine hands-on electronics with physics. This kit teaches basic circuit principles, component polarity (diodes, resistors), and motor mechanics. A great project for classroom activities, science fairs, or as a unique gift for future engineers.

USB Powered & Safe Design: Powered simply by 3pcs CR1620 batteries (not included), no high-voltage danger. The smooth bearing rotation ensures long spin times, and the sturdy fiberglass board prevents damage during assembly.
