Bluetooth Square Wave Music Tesla Coil Scientific Experiment Toy with 20cm Artificial Lightning – Rotating Type

Features:

.Desktop integrated mini solid state Tesla coil finished product, the primary and secondary are all made of PCB, discarding the traditional solenoid secondary Tesla coil, highly integrated, cleaner and safer. 
.The Tesla coil power supply is only 32v DC, and the low-voltage power supply ensures safety, and the effect is stronger than most desktop-grade commercial half-bridge Tesla coils on the market. The 2M high-frequency sub-level, there is no pain even if you touch the arc with your hands.
.With a toroidal coil, plug in the power supply and you can experience the charm of lightning on the palm.
.Bluetooth connection can play square wave music, increasing its playability. At low frequencies, you can freely play the arc between your palms. The frequency of the music mode is higher, and the arc will burn when concentrated at one point. 
.The power supply is a DC power adapter, which does not need to be grounded, and is more stable. The heat sink is equipped with a temperature control switch. The power supply has over-current protection. The pulse width of the music mode is limited and multiple protections are provided. 
.There is no fan to dissipate heat (because the heat is very low), do not run at maximum power for too long, so as to avoid the temperature control protection is too fast.
.Instructions for Use: Switch down to fixed frequency mode, the knob to adjust the arc frequency and size, pause in the middle of the switch, switch up to music mode, use the audio cable to link the phone to the maximum playback, the knob can adjust the size, the right knob Control the size of the arc and twist the clockwise pointer. The left knob controls the fixed frequency frequency, and clockwise speeds up the arc spray frequency. It is best not to keep the maximum arc on in the music mode, so as to avoid the temperature control protection too fast. If the arc in the music mode is turned on to the maximum and sometimes discontinuous, this is caused by the power protection of excessive power. At this time, a small arc should be opened appropriately.
.A very nice gift for science and intelligence, there is a curved light bulb, which will rotate with the power on, forming a circular lightning effect, and rhythm with the music.
