Spark your passion for physics, electromagnetic fields, and soldering with the DIY Mini Tesla Coil Kit BD243C!
Curated and quality-tested by TNNJoy for electronics hobbyists, STEM students, and young engineers (ages 14+), this entry-level DIY kit allows you to assemble a fully functional miniature Tesla coil from scratch. Powered by a high-power BD243C NPN transistor and secondary copper winding coil, this kit demonstrates high-frequency AC wireless power transmission by lighting up neon bulbs and gas discharge tubes right in mid-air!
Key Features & Science Highlights:
Wireless Power Transmission Demonstration: Generates a high-frequency electromagnetic field that wirelessly illuminates neon bulbs, fluorescent tubes, and gas discharge indicators when brought close to the copper secondary coil.
BD243C High-Power Transistor Core: Driven by an authentic BD243C power transistor with an aluminum heatsink for stable thermal dissipation during continuous operation.
Fun & Rewarding Soldering Practice: Excellent beginner soldering project featuring clear component labels on a durable FR-4 glass fiber PCB.
Compact Desktop Science Display: A fascinating physical science gadget that serves as a captivating desk ornament and physics classroom demo.
Dual Audio / Power Input Options: Includes 3.5mm audio jack terminals allowing high-frequency plasma spark modulation to play subtle music tones.
