Frequently Asked Questions (FAQ)

Q: What is a Bluetooth Tesla Coil Speaker?
A: A Bluetooth Tesla Coil Speaker is a fascinating science gadget that creates real electrical arcs while playing music through plasma instead of a traditional speaker cone. It's a unique demonstration of high-voltage electricity, wireless energy transfer and sound technology.

Q: Can you use it without music?
A: Yes, simply switch to "Lightning mode" to have a mesmerising continuous stream of lightning arcs without any music input—a fascinating display!

Q: How can lightning make music?
A: Unlike a traditional speaker, a Tesla Coil creates sound by rapidly changing the frequency of its electrical arcs. These changes cause the surrounding air to vibrate, allowing the plasma itself to produce music—an incredible demonstration of electrical engineering in action.

Q: How do I connect the speaker?
A: Simply plug in the Tesla Coil, pair it with your phone, tablet or other Bluetooth-enabled device (or using an AUX cable; see below), and you're ready to stream music wirelessly in just a few seconds.

Q: Can it connect to audio without Bluetooth?
A: Yes, the unit includes a 3.5mm AUX in socket, so you can connect it to music sources without needing a Bluetooth enabled device.

Q: Can it play real music or just sound effects?
A: Yes. The Tesla Coil can play real music by modulating its electrical arcs. It works best with square wave audio, and we've included a link to free sample tracks in the instruction manual so you can experience the best performance straight away.

Q: Is it safe to use indoors?
A: Yes. When used according to the instructions, it's suitable for indoor use. As with any high-voltage device, it should be operated away from flammable materials, metal objects and sensitive electronic equipment, and should always be used responsibly.

Q: Does it come fully assembled?
A: Yes. The Tesla Coil arrives fully assembled and ready to use. Simply connect the power supply, screw in the discharge needle, pair your Bluetooth device and start creating spectacular lightning effects within minutes.

Q: Can I purchase this as a DIY kit to solder together myself?
A: No, many of the components in this kit are far too small to be soldered by hand. This kit is assembled robotically at the factory.

Q: Who is this Tesla Coil suitable for?
A: It's perfect for science enthusiasts, electronics hobbyists, makers, teachers and anyone looking for a unique STEM gift or conversation piece.

Q: Is this safe and suitable for kids?
A: Yes, it's safe for kids, but we recommend adult supervision for anyone younger than 16. Please adhere to the following safety requirements. Keep away from flammable or explosive materials. Avoid arcs striking other electronic equipment as damage could result. The sound produced can be loud, avoid excessive exposure. The energy discharged in 'Music mode' is greater than in 'Lightning mode' so avoid touching the arcs in 'Music mode'. Do not disassemble the unit.
