Feature 1、HIGH POWER AND MULTIPLE CAPABILITIES: This is a PLLSSTC music coil. Possess beautiful shape, relatively large power, good arc effect, more functions. Also a plasma speaker that can use an electric arc as a speaker to play all kinds of music 2、EXCELLENT PROCESS QUALITY: The circuit board use the latest power devices and processes, coupled with reasonable design, to achieve better and more stable quality. The primary coil adopt original design and process, and the secondary coil adopt high definition epoxy resin adhesive coating, which is more beautiful and lasting 3、LONG WORKING TIME: Ordinary music coils are usually damaged quickly because of high temperature or high voltage and high current, for a variety of problems, the use of excellent components, with reasonable design, modern materials, etc., improved coil, not afraid of long term work and heavy use, after 24 hours of continuous work test experiment 4、BEAUTIFUL APPEARANCE: Usually enthusiasts do their own music coils, limited by various conditions, can only make some basic functional works, the appearance is rough and simple. This one bring you some works worth collecting, the appearance level is exquisite 5、WIRELESS POWER EXPERIMENTS: You can also use this small music coil to explore wireless power transmission and continue the unfinished business Item Type: Music Coil Material: Acrylic, stainless steel, PCB Electric Spark: Approx. 30mm / 1.18in Functions: 1. Plasma Speaker: We have added a sound modulation circuit to this music coil, which allow the electric spark to vary in amplitude with the music signal, producing sound and serving as a plasma speaker. Can connect to various devices via Bluetooth or sound cable to play music with good sound quality and volume. 3. Ion Windmill: An electric arc is a high temperature plasma that can heat the air, and the heated air flow generate thrust. When the arc jets from both ends of the PCB windmill in opposite directions, it start to rotate. 4. Ion Ring: We use a thin, elastic metal wire as the discharge end. When the coil start working, the top emit an arc that generate thrust, the arc will sway and rotate due to the instability of the thin wire. If we start long exposure shooting when the wire starts to sway, we will get a super cool picture. 5. Wireless Power Transmission Experiment: music coil for wireless power transmission. You can also use this small music coil to explore wireless power transmission and continue unfinished business.
