Multifunctional BT music Tesla coil has the function of wireless transmission, produces touchable electric arc, lights up lights, and plays music with high sound quality. With the Tesla coil, you can create dazzling artificial arcs that can be used not only in games or art but also for various scientific experiments such as wireless power transmission, wireless light illumination, insulator voltage testing, sewage treating process, etc. And teachers can use it to demonstrate the principle of voltage boosting to students, high-frequency skin effect, etc. It is a perfect teaching tool to arouse students' interest in science, also can be a fine gift. Features: Beautiful Appearance:It is compact in size, light and portable, beautiful and stylish, with fine durability by adopting a strict production process. The electric arc effect of this Tesla coil is very cool and interesting, and it is also a beautiful decoration for your home at night. Easy to Use:Two rotary knobs design for you to adjust the power (the size of the arc) and working frequency (the speed of the arc). And with a push button to adjust between fixed frequency mode (left), music mode (right), and close mode (middle). Touchable Artificial Arcs:When a metal pin is used as the discharge end, the coil generates a significant amount of heat, and no touching. This process produces a palpable arc that, when touched by the hand, provides a sensation similar to a soothing hand massage at a SPA. Wireless Transmission:The Tesla coil can generate a high frequency and high-pressure electromagnetic field so that the lights containing conductive gases can be illuminated by the electromagnetic field. Includes fluorescent light, LED light, neon light, and some rare gas-glass tubes. BT Connection & Music Plays Function:The electric arc generator features a BT connection function that allows it to plays music from mobiledevices. By switching to the music mode, users can enjoy their favorite songs with improved sound quality and volumes, thanks to the optimized circuit. Experimentation Teaching Aid:It is a perfect teaching tool to spark students' interest of science, suitable for various scientific experiments such as wireless power transmission, wireless light illumination, insulator voltage testing, sewage treating process, etc. And teachers can use it to demonstrate the principle of voltage boosting to students, high-frequency skin effect, etc. Note: Shipped without powersupply, customers need to provide their own 48V, 1.5A and above, interface specifications 5.5 * 2.1 power adapter. Attention Please: This product is a DIY product, handmade, and can only be used for ornamental purposes, not for professional use, such as insulation tests, high voltage ionization tests, and so on. This product due to the small size of large power, does not work for a long time, and high temperature will permanently damage the product. Working time is determined by ambient temperature, generally not more than 5 minutes (fixed frequency maximum power), and music mode generally not more than 3 minutes, depending on the actual use decision. And please stayaway from explosive materials. Due to the serious interference with metal, please do not use electronic devices such as cell phones and computers close to the coil, so as not to cause damage to the product. The solid-state Tesla coil generates a large amount of ozones during discharge, so make sure that the experimental area is well-ventilated.
