Many electronics circuits and projects for learning in simple ways.

Small High Volts shock using 2SC1815 transistor

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!

High volt shock using 2SC1815 transistor

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.

  1. Everyone one please careful be if building this circuit!!! The Voltage here can kill or injure You!! PLESE BE CAREFUL!!!

  2. And is this circuit safe to use to on other people, or will it “harm or injure them”

  3. Hi,Angus someone
    It is small size circuit.
    All transistor are NPN types.
    and watts output very low or current lower than 1mA.

  4. Sorry, just had to ask.
    I’m not that good with electrical knowledge.
    And what kind of Transformer should I use?

  5. can be used 2SC1906

  6. erro in calclutie ??!!!

    8v x 34.6 mA
    shoud be
    8000 mV x 346 mA

    or 8 volt x 0.346 amp

    im mean ccome one
    mm michael

  7. how to increase the output current?

  8. This circuit will probably only cause a pretty good jolt because the current is so low. With Model T coils which you may still be able to get from JC Whitney you can get an output of 40 or 50 thousand volts. But I would caution anyone against using these types of circuits as gags or any other misuse, because there is always a danger of an undiagnosed or unknown heart condition. You always treat a gun as loaded and you should have the same respect for electricity.

  9. plz..tell me ..what will be the frequency of alternation…..

  10. Are both transistor base interconnected?? and are resistor value is 0.5Watt? plz help

  11. Do you think that this can shock people with 220 volts output only?
    Based on their comments above, I’m worrying that it will not even shock me, because they said that its low output current…
