Tesla Coil HFSSTC Electronic Candle Plasma Flame Kit

Explore High-Frequency Plasma and Wireless Energy in Action

This HFSSTC Tesla Coil Electronic Candle Plasma Flame Kit is a compact, high-frequency experimental platform designed for classrooms, labs and hobby workshops. Operating from a DC 36-40 V supply, it generates visible plasma arcs and an electronic "candle" effect, allowing learners to observe high-voltage, high-frequency phenomena and wireless energy transfer in a controlled setting.

The kit is based on a solid-state Tesla coil design with an operating frequency of about 15 MHz. The secondary ignition coil uses a ceramic core with 0.3 mm enamelled wire wound for 65 turns, providing stable performance and consistent plasma discharge. The main unit measures approximately 5 cm x 5 cm x 8 cm (without the secondary coil), making it suitable for benchtop demonstrations and portable teaching setups. For reliable operation, the system uses a 24 V cooling fan and a 5 cm x 5 cm heatsink to support continuous runtime of more than 30 minutes under test conditions.

All major components required for assembly are included: primary coil, upper and lower PCB boards (with 0805 red LED already soldered), ceramic secondary coil, 6.2K resistors, 2K and 3K precision resistors (1%), IRF250 power device, 2W 200 Ω resistor, 24 V fan, heatsink, M3 x 50 mm screws, 5 mm ABS spacers, extended pin headers, 2P bent pins, 4P busbar, capacitors rated up to 3 kV and 1 kV, 2.2 µH I-shaped inductor, in-line magnetic beads, A03 self-locking switch, DC005 power jack, and 5 mm white-green LED. Once assembled, the device produces a stable plasma flame that can be drawn out using a metal object such as a screwdriver or wire, visually demonstrating high-frequency electric fields and ionization of air.

Basic operation is straightforward: connect the main unit to the secondary coil, ensure the coil is clear of nearby objects, then connect the 36-40 V DC power supply and press the ignition switch. The arc should be led out within a few seconds by bringing a metal object close to the discharge area. The kit is intended for supervised use by adults or advanced students with a basic understanding of electrical safety. During operation, it can generate electromagnetic interference to nearby electronics, so it should be used away from sensitive equipment. It is not suitable as a toy and must be kept out of reach of children. Users must avoid touching the ignition coil, primary coil or electronic components while powered and keep flammable or explosive materials away from the work area.

FAQ

Q: What power supply do I need?
A: Use a regulated DC power supply within 36-40 V capable of providing at least 2 A. Ensure correct polarity and stable output before switching on.

Q: Is this kit suitable for beginners?
A: It is suitable for technically inclined beginners under supervision and for students or hobbyists who already understand basic electronics and high-voltage safety practices.

Q: Can it run continuously?
A: Under test conditions, the unit can operate continuously for more than 30 minutes thanks to its cooling fan and heatsink. Allow rest periods if components become excessively warm.

Q: Will it interfere with other devices?
A: The 15 MHz operation can cause electromagnetic interference to nearby electronic equipment. Use it away from sensitive devices and instrumentation.

Q: Is it safe to touch the plasma arc?
A: Do not touch the ignition coil, primary coil or electronic parts while operating. Only approach the discharge area with suitable metal tools as described, and always follow high-voltage safety precautions.
