Winding the transformer:
Winding A to C is 30 turns #22AWG magnetic wire center tap at B, making winding AB and BC 15 turns each. Use ferrite bar or antenna bar as the winding core. After winding A,B and C, start winding the output windings above it using #26AWG or #28AWG magnetic wire 300 turns.
You can use any transformer with center tap available.
Note: This circuit can generate a very high voltage that can cause electric shock. This is not a toy , don't play with this circuit.
This might be the thing I need for my battery powered tesla coil.
ReplyDeleteYeah, this one of the basic high voltage generator circuit that uses only minimal parts. even simpler than using 555 timer
ReplyDeleteI've done it, but it does not work.
ReplyDeleteHow much ferrite bar's size?
Please, help me. Thank you very much!
Ordinary ferrite bar or antenna bar will do. Try reversing the connection of the winding. no output meaning no oscillation in the circuit, which is usually due to reverse winding connection.
ReplyDeleteI tried again, but very weak electric current output. Touching no sensation of shock.
ReplyDeleteif anyone has been successful, please provide detailed guidance (with video as well).
Thank you!
what is the 10Meg resistor for?
