Yoqanr Jacob's Ladder Mini DC Induction Kit — High-Voltage DIY Tesla Coil

Overview

The Yoqanr Jacob's Ladder Mini DC Induction Kit puts high-voltage demonstrations into a compact, hands-on package. Perfect for students, makers, and curious hobbyists, it blends a striking visual arc with practical setup that invites experimentation and learning without overwhelming setup time.

What’s included

The system features a purpose-built PCB frame aligned with the high-voltage module for a tidy, reliable start. The bundle combines a ZVS high-voltage power supply with a Jacobs Ladder kit; the ladder itself requires assembly by the user to complete the build.

• A customized PCB fixed to the frame for straightforward wiring and stable operation.
• A ZVS high-voltage power supply designed for durability and consistent performance.
• A Jacobs Ladder kit that you assemble, enabling a hands-on learning experience.
• An insulated horn electrode mounted on the base plate to protect surfaces from heat exposure.
• Clear guidance noting that a separate power supply is required (24 V DC, 150 W or higher).

How it works and what you’ll see

Once power is supplied, the ladder displays a rising cascade of glowing arcs that trace the path between rungs. The subtle crackle and warm glow offer a tangible look at high-voltage dynamics, making it a memorable classroom or maker-space demo.

The horn electrode sits on an insulated base, helping keep the surface clean while you observe the arc’s movement and rhythm as it lights up the ladder.

Ideal uses

• Classroom demonstrations, STEM clubs, and science fairs where a dramatic visual aids understanding of electricity.
• Makespace projects and DIY experiments that explore safety, setup, and basic high-voltage principles.
• Personal projects for enthusiasts who enjoy electronics-inspired displays and Tesla coil-like effects.

Power, safety, and setup notes

The kit requires a separate switching power supply rated above 24 V and at least 150 W. The design includes an insulated base and robust components to support repeated use with proper precautions. Follow standard electrical safety practices when operating.

Why choose Yoqanr

• A tailored PCB frame keeps components aligned for quick, repeatable setup.
• The welded ZVS supply and the assembly-needed Jacobs Ladder kit offer a satisfying mix of reliability and hands-on building.
• An insulated base plate helps protect surfaces and extend the life of the copper wiring during demonstrations.
