It is a small high volts shock circuit, pressure from the low current. It is best for fun play. In-circuit has a few tools just 2 small NPN transistors, 2 resistors, and 1 transformer. So easy to makes and cheap. Pin detail of a small high volts shock circuit: When switch S1 closes the circuit for feed power supply gives with Q1 and Q2. current flow through the coil of the transformer of the primary and touch limit the current with R1 and R2 before convert comes in point B of Q1 and Q2.
this builds Q1 and Q2 bias by a transistor that bilateral alternate operates all the time. When Q1 bias builds have current flow change during a half on of coil primary and when Q2 builds have current flow during a half below of coil primary.
Which operates alternation of Q1 and Q2 can build be the electric current alternates to come out at coil secondary cell making this circuit should use carefully. because of might causation dangerous from the electric changing current.
Note: we can use many transistors which are NPN kind and small size. (C458, C1815, C828) This circuit can collect on the breadboard or Universal board PCB.
And use current about 34.6mA at a voltage supply is 8.4Volt, can provide the output of ACV-203Volt
If I test to think about current output. as principle Power in = power out:
Power in = V x I; V(battery) = 8.4Volt and I(current of circuit) = 34.6mA
Power in = 8.V x 34.6mA = 290mWatts
So, Power out also about = 290mWatts
Iout = 290mWatts / 203Volt = 1mA
Parts you will need
Q1,Q2: 2SC458,2SC1815, 2SC828 NPN transistor
R1,R2: 10Kohm 0.5W Resistors
T1: 220Volt AC primary to 9Volt-0-9Volt,250mA secondary transformer
In the US use 110Volt AC primary. But it is low voltage up to about 110Volt.
