Simple Portable Electronic Pulse Massager circuit

Do you feel tired muscle? You may try this, a simple portable electronic pulse massager circuit. It will help you relax the muscles with a frequency pulse.

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

Look at Figure 1 is the Simple Electronic Pulse Massager circuit diagram. It uses 9 volts battery.

Handheld Electronic Pulse Massager circuit

Figure 1 is a Simple Handheld Electronic Pulse Massager circuit using CS9013 transistor

The working of the circuit will begin with transistor-Q1 is connected as the frequency generator circuit.

Which this frequency will depend on R1, R2, C1, C2, L1, L2 and VR1. We can adjust frequency by VR1.

Then, LED1 will flash as a frequency that it generates. Next, it is increased to step up an input voltage from L2 to L3.

It has a high voltage pulse of about 50 volts, output. And it is pulse narrow range and lowest current, too.

So, Not harmful to the user in any way. This voltage will flow to VR2 to adjust the pulse voltage before sending it to the output.

How to assemble circuits

First, we make the PCB as Figure 2 that is an actual-size of Single-sided Copper PCB layout.

Figure 2 actual-size of Single-sided Copper PCB layout.

Then, assemble components as Figure 3 is the components of PCB. By putting all parts that lower than higher such as Diode, resistors, etc.

The testing

When we assemble the circuit successfully as Figure 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 to adjust the VR1.
  • Next, notice the flashing of LED1 will slowly or fast as adjusting VR1.
  • If you try as above, it shows that this project ready to uses.

We should connect both output point with a metal plate, then place them on the 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 the right.

Our muscles, it will begin to pinging and more. According to the strength of adjusting VR2.

Then, try to rotate 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.

Component list

Resistors size ¼ W +-5%
R1: 20K
R2: 50 ohms
VR1: knob 500K
VR2: with knob 10K

C1: 2.2uF 50V Bipolar
C2: 100uF 16V Electrolytic

LED1: 5 mm LED 5 as you want.
D1, D2: 1N4148 0.75A 200V Diode

L1-L3: the small output transformer, TO-601
Universal Box
SPDT- Single-pole double-throw switch = 1 Pcs.
PCB as Figure 2, wires, etc.


Flatron said” 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)


Instructions for use

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