This is small high volts shock circuit, pressure from the low current. It is perfect for fun play. In circuit has a few component just two small NPN transistors, 2 resistors and a transformer. So easy to builds and cheap!
When switch S1 close the circuit for feed power supply give with Q1 and Q2. By current flow through coil of transformer of the primary and touch limit current with R1 and R2 already change come in pin way B of Q1 and Q2.
It make Q1 and Q2 bias by transistor that bilateral alternate work all the time. When Q1 bias make have current flow change during a half on of coil primary and when Q2 make have current flow during a half below of coil primary.
Which work alternation of Q1 and Q2 can make be the electric current alternates to come out at coil secondary cell building this circuit should use the carefulness. because of might born dangerous from the electric alternating current.
I test circuit on breadboard.
Note: You can use many transistors that is NPN type and small size. (I use C458 or C1815 or C828) This circuit can assemble on breadborad. or Universal board PCB.
And use current about 34.6mA at voltage supply is 8.4V, can provide output of ACV-203V
And use small transformer 0.25A as video below.
If I test to think about current output. as principle Power in = power out (around..)
Power in = V x I; V(battery) = 8.4V and I(current of circuit) = 34.6mA
Power in = 8.V x 34.6mA = 290mW
So, Power out also about = 290mW
Iout = 290mW / 203V = 1mA
It is low current only.
