• Music Tesla has wireless transmission and speakers. It generates high-frequency alternating current through chip oscillation and audio control. The arc pushes the air to generate sound, supporting wireless power transmission.
• The size of this Bluetooth music tesla coil is only 4.17 inches, and a larger top boost coil is upgraded. The optimized Tesla coil lightning arc is long and thick, and can emit a beautiful arc of more than 10 cm, showing a perfect lightning effect.
• It is a perfect teaching tool to stimulate students' interest in science. The artificial simulation of lightning can be used as a physical experiment. It can light the air pipe and various bubbles.
• Connect Bluetooth and play square wave music. The arc of Tesla coil will beat with the music. At medium power, when you touch it with your hand, it will feel itchy, which improves students' learning and exploration ability. Let the lightning dance to the rhythm of the music. Different discharges produce different tones.
• Tesla modules can be placed horizontally or vertically, which is simple to operate. Just tighten the discharge pin and insert the power supply to see the lightning.
