Handheld Tesla Coil Gun Pink What this product does and why you might need it Compact, portable frequency coil gun for hobbyists, educators, and audio visual demonstrators. Adds audible and visual interest through frequency discharge and a music playback mode that synchronizes sound with the coil output. Small footprint and handheld design make it easy to position for demonstrations, experiments, or stage effects where a compact source of frequency discharge is required. Key features Color: Pink. Form factor: Handheld design with a diameter of 2.1 inches and a height of 2.95 inches for easy handling and transport. Music playback: Built in music mode. After powering on, move the mode switch to the music position (right), search for the BT device via Bluetooth on your phone or computer, and connect. Note that the unit plays square wave music only. Power limits: Maximum input voltage for the power interface is 48V. Operate within this limit to avoid damage. Performance: frequency operation produces strong electromagnetic effects; expect significant heat generation and metal interference during use. Safety and usage notes Heat management: frequency operation causes the power tube to generate substantial heat. Monitor the temperature of the heat sink during use and stop operation if temperatures become excessive to avoid component damage. Electronic interference: The coil produces strong interference with metals and nearby electronics. Do not place mobile phones, computers, or other electronic devices near the coil during operation to prevent damage and reduce interference. Follow proper handling procedures for voltage and frequency devices. Use in controlled environments and keep bystanders at a safe distance. Practical applications Classroom demonstrations: Visualize and explain frequency electrical discharge and electromagnetic effects in physics or electronics lessons. Hobbyist projects: Integrate into DIY audio visual setups or electronics benches for testing and experimentation. Stage or photo effects: Provide compact synchronized audio and visual effects for small scale performances or creative photography when used with appropriate safety measures. Specifications Color: Pink Type: Handheld Tesla coil gun Diameter: 2.1 inches Height: 2.95 inches Maximum input voltage (power interface): 48V Music capability: Bluetooth connection to phone or computer; square wave music only Keep these points in mind while using the device to ensure reliable performance and to protect the unit and nearby electronics from heat and interference.
