Build a Tesla Coil Circuit Diagram

Build a Tesla Coil Circuit Diagram. The Tesla coil described here can.generate 25,000 V. So, even though the output current is low, be very careful! The main component is a flyback transformer from a discarded TV. A new primary windin_g is needed. Begin by winding 5 turns of #18 wire on the core. Then, twist a loop in the wire, and finish by winding five more turns. 

Wrap with electrical tape, but leave the loop exposed. A four-tum winding must be wound over the ten-turn winding that you`ve just finished.That is done the same way. First wind two turns of# 18 wire, then make a loop, and finish by winding two more turns. Again, wrap the new winding with electrical tape, leaving the loop exposed. When the windings are finished, the two loops shouldn`t be more than 1/.-inch apart, but take care that they do not touch. Connect a 240-U resistor between the two loops. 

The modified transformer now should look like the one shown. Connect the transformer as shown. The 27 -U resistor and two transistors should be mounted on a heatsink and must be insulated from it. The output of the high-voltage winding should begin to oscillate as soon as the circuit is connected to a 12-V de power supply. Ifit does not, reverse the connections to the base leads of the transistors. In normal operation, you should be able to araw l-inch sparks from the high-voltage lead using an insulated screwdriver.
