Simple Handheld Electronic Pulse Massager circuit

This is a simple handheld electronic pulse massager circuit. Which it helps to relax the muscles with electric pulse waves. Ideal for those muscles all the time, such as standing or hand throughout the day. This machine is small And is powered by 9 volts battery, so it’s safe. You can also customize the frequency and strength as well.

The working principle.
On Figure 1 is Handheld Electronic Pulse Massagger with 9 volts. The working of circuit will begin with transistor-Q1 is connected as the frequency generator circuit. Which this frequency will depends on R1, R2, C1, C2, L1, L2 and VR1. We can adjust frequency by VR1.

Then LED1 will flash as frequency that step up at L3. Which is high voltage pulse about 50 volts and be pulse narrow range. And This current is lowest so Not harmful to the user in any way. This voltage will flow to VR2 to adjust the pulse voltage before to output.

How to assemble circuits
Firstly we make the PCB as Figure 2 that is an actual-size of Single-sided Copper PCB layout. Then assemble components as Figure 3 is the components of PCB. By put all parts that lower than higher such as Diode, resistors etc.

The testing
When we assemble circuit successfully as Fgure 4. Then apply a 9 volts power supply from battery by a positive polarity to +9V and the negative polarity to GND of this circuit. Now LED1 will flash then test adjust VR1 to see then notice flashing of LED1 will slowly or fast as adjusting VR1. If try as above will show that this project ready to uses.

Application
We should connect both output point with a metal plate, then place them on body, the two points a little apart, Next Cover with a wet cloth next to the modest size of 5×5 inches.

After that adjust VR2 to the full left, then apply voltage to the circuit, next rotate partially the volume to right. A our muscles, it will begin to pinging and more, according to the strength of the spin VR2. Then Try rotating VR1 to change frequencies as needed.

Repair of this project.
1. LED lights throughout, showing that C1, C2 short. And pin CE of Q1 short.
2. LED flash but tried, muscles do not jerky, indicating that the lack of L3.
3. Adjust the frequency did not, indicating that VR1 shock.

How to use it
1. Do not use both metal plate touching the head or temples.
2. Do not use on pregnant women
3. Do not apply DC adapter instead of 9 volts battery.
4. Cases, the side effects, should see a doctor immediately.
5. Do not bring both metal plate to the area of ??the wound.

  1. I CAN NOT UNDERSTAND THE OUTPUT TRANSFORMER DETAILS. IS IT FERRITE CORE ?

    PLEASE SEND DETILS.

    THANKS.

  2. How do i make L1, L2 & L3 transformers?

  3. Por favor,necesito detalles de L1,L2,yL3.
    Muchas gracias
    Onurba

  4. L1,L2 and L3 is output transformer.
    This transformer is an old components.
    (I thing is is 2×600 ohm/8 ohm transformer)
    it’s primer side 3 pin (2 bobin)and seconder side is 2 pin(one bobbin)
    *if you folow circuit on pcb image you will understand

  5. what is the frequency and amplitude of output pulse generated by this massager?

  6. I could not get exactly how you made transformer using inductors L1, L2 and L3. I’ve traced their positions using the pcb layout you provided but don’t know of what values they are?

  7. how to make or winding out put trans for mer.what is conection circuit and pcb layout not match

  8. using ENGLISH words is not all there is to speaking ENGLISH. the ENGLISH language also requires ENGLISH sentence structure, which most of your word structure lacks, making your message hard to understand.

  9. Hi Steve hoke,
    Thanks for your feedback.

  10. we don’t know about transformer u mentioned
    we want details about it

  11. I CAN NOT UNDERSTAND THE OUTPUT TRANSFORMER DETAILS. IS IT FERRITE CORE ?

    PLEASE SEND DETILS.

    THANKS.
