- Description:
____________
This product is a booster coil production suite, the circuit is simple and reliable, with a professional line drawings, electronic research convenience enthusiasts
Uses: high school science experiment, electronic equipment, negative ion generator, scientific small production. This circuit is generated when the stable high frequency arc, high temperature, can easily ignite combustible materials, so it was called the plasma lighters
Parameter:
15KV transformer outside dimensions of approximately: 27×16×21mm
Input voltage: DC 3.7V-4.2V (limit 12v, easy to damage not recommended, this transformer is equally applicable to 12V input voltage, but requires a corresponding increase in the base of the feedback resistor to about 150Ω ~ 1.5KΩ, its resistance should be large to replace a small adjustment, or burned transistor or transformer
There are two primary windings, a primary winding, a feedback winding, the secondary output of high pressure. Other: 15KV transformer designed for maximum output, limit output can not exceed 15KV, is one centimeter arc, a higher output voltage is likely to damage the transformer.

4pin header ,which 2 pins short with jumper?
The four pin switches confuse me
2 pin + and 2 pin - = 4 pin
we can also attach a antenna
Maybe not
But I've attached and it worked more clearly
I don't know actually 🫣
If I want to connect an antenna…where should i connect it? L1?
Wireless?
Yes bro
where?
