1: Plasma - We have added an audio modulation circuit to this for coil, which allows the arc to follow the amplitude of the music signal and produce sound, making it a plasma . Through Bluetooth or audio cable, various devices can be connected to , with good sound quality and high volume (you can learn through promotional videos) 2: Lighting in the interval - for coils can generate a high-frequency and high-voltage electromagnetic field, and when lamps containing gas come close, the gas inside the lamp will emit lights under the action of the electromagnetic field. Common lamps include fluorescent lamps, incandescent lamps, neon lamps, disinfection lamps, and some rare gas glass tubes. 3. Different lighting fixtures have different effects, and due to the high power of our coil, the effect and distance of lighting through space are currently the on the market. Ion windmill - An arc is a high-temperature plasma that can heat air, and the flow of hot air generates thrust. Therefore, when the arc is sprayed in the opposite direction from both ends of the PCB windmill, it begins to rotate. 4: Ion wreath - We use a thin and elastic metal wire as the discharge end. When the coil starts working, an arc is sprayed from the top to generate thrust. Due to the instability of the thin wire, the arc will shake and rotate. If we initiate a long exposure when the wire starts to shake, we will get a super cool image. 5: Wireless Transmission Experiment - The intention of Nikolat 's invention of the for coil was for wireless transmission, and also use this small coil to explore wireless transmission and continue Nikolat 's unfinished business. This is a for coil. High power, good arc effect, and multiple functions. It is also a plasma thatcan use an arc as a speaker to play music. Safety warning!! Operating instructions: When working on for coils, do not touch the coil part or arc to avoid burning the skin. Do not use metal objects to contact the surface of the coil to avoid burning it out. Stay from electronic devices: for coils can generate powerful pulsed electromagnetic fields, and some electronic devices are prone to interference. For safety reasons, it is to stay from all electronic devices. And that your socket has a grounding wire connection function. Plug Type:US Plug, it applies to Canada, India, Mexico, Thailand, Taiwan, the , the Philippines and so on.
