Okay, this is for the tinkerers, hobbyists, and science lovers. This DUNSIHUI module takes a small DC input (3.6V to 6V) and boosts it up to a whopping 20,000 volts. Yeah, you read that right—20kV. It works on the Tesla coil principle, creating high-voltage pulses that can produce arcs up to about 5mm. It’s compact, efficient, and pretty straightforward to use: connect a battery and a switch, and you’re in business.
It’s meant for experiments, educational projects, or small high-voltage applications like negative ion generators, ignition setups, or just cool sciency demos. The input wires are red (positive) and green (negative), and the output is via two high-voltage wires. Each module is about 110mm on the leads, so you’ve got some room to work.
Important safety note: This thing is not a toy. Always be careful with high voltage. Avoid running it without a load, and don’t run it for more than 5 seconds at a time to prevent overheating. The arc distance depends on your power supply’s current capability—more current means longer, more stable arcs. Great for learning about high voltage, DIY projects, or adding some spark to your experiments. Just use common sense and proper safety gear.
