STARK Mini Tesla Music Coil Speaker Plasma Singing Loudspeaker Experimenting Device Teaching Tool Desktop Toy
Features: Design Intention: Use a newly designed PCB circuit board to expand the area of the heat sink, adopt better components, and improve the sound quality and volume a lot. Easy to Use: The size is small, beautiful and easy to display. The circuit design is reasonable, the fan with large air volume is silent, quiet and no noise, ensuring long-term use. Multi-function: 3.5MM audio input is convenient to connect to mobile phones and computers to play any music. In addition to watching electric arcs and listening to music, the product can also be used to ignite in space, light up gas and lamp tubes, without any touch or connection. Science Educational Toys: When this Tesla coil works, it is absolutely magical for children or adults. You will be fascinated by this Tesla coil and sigh. Instructions for Use: 1. Assemble the electrode needle (the electrode needle must be assembled before starting up). 2. Plug the 24V power supply of the product into the socket on the main body of the product, and toggle the switch to generate an arc. 3. When you need to play music, connect the audio cable to the phone, and play it on the phone first, and finally connect the other end of the audio cable to the product body. Note: 1. This product has a high arc frequency, and it will burn if you touch it. Please do not touch the arc. 2. The discharge needle is relatively sharp, children please use it under the care of their parents. 3. After power-on, it is not recommended to touch the components on the circuit board except for the switch. 4. If the heat sink is hot, please cut off the power and let it go for a period of time. For Ages: 12+

This coil is impressive, nice dancing spark from the needle tip and it makes leds glow at a distance. As expected it can irritate electronics located nearby. When I had it running the first time, I noticed the heat sink and particularly the corner bolts got either very hot or I was getting a shock. Today I used a multimeter to check for voltage and found none on either the sink or screws. They did appear to get quite hot rather quickly. I tried to use an IR thermometer and a needle probe digital kitchen thermometer to see how hot these parts were. The IR did not pick up much temperature rise and the digital thermometer was scrambled by the emissions. I turned off the coil and the thermometer regained its mind. Holding the thermal probe tip against the bolt the thermometer reading did slowly rise and eventually showed the screw was quite hot. While I was running the coil I noticed the fan pulsing. The fan speed was fluctuating but basically running. Whatever the heat sink is trying to cool is really hot, likely the cooling system is marginally capable of handling the thermal load. I would be reluctant to leave this device running unattended. Given how the digital thermometer behaved, I am reluctant to try and plug this into my I phone to test the speaker mode.
