DIY PEMF can save you money and even replace many of the machines available on the market. Also, building your own machine can help educate you about how PEMF works. Furthermore, you will get a better understanding of what it takes to make a PEMF device. Likewise, you will see how some machines can be very expensive because of all the marketing and business costs.

Today, we can ignore all of the extra costs and just concentrate on making a DIY PEMF machine. Actually, it is pretty easy to make a simple device that will emit pulsed electromagnetic fields. You can probably find all the needed tools in your junk drawer. However, you will need a soldering iron to complete this device. All it will take is a little time and you will be getting similar results to machines costing thousands of dollars.

Basically, this is a simplified how-to for people with a little DIY experience and understanding of electronics. However, as you follow along you may notice that it is easy enough to do for almost anyone. Most importantly, there are dangers such as being electrocuted or burned. Please be careful and observe the directions and warnings for the individual products.

OK let’s make a DIY PEMF device!

There are two basic types of PEMF devices. Most high output machines use powerful transformers and big capacitors to produce a big spark. The result is a square wave charge that delivers powerful treatments you can actually feel pulsing though your body. Our MegaPulse is this type of machine. Alternatively, PEMF’s can be produced with a digital waveform generator and amplifier. StemPulse and Sedona Pro work this way.

PEMF Controller Module

The machine we are displaying here uses a digital waveform generator and amplifier. Simply, we purchased the components on Amazon and screwed them together. From the image above, you can see the screw terminals for attaching wire. Everything is clearly marked. Literally, it will take less than a half hour to clip some wires and insert them into the connectors and tighten the screws.

Make sure the 12 volts from the transformer is attached with correct polarity to the waveform generator and amplifier. Then, attach the output from the waveform generator to the input of the amplifier.

The Transformer

We used some little 2 amp transformers when we first tested this device. They worked OK but they heated up very quickly and we knew they wouldn’t last. The transformer we chose is capable of 15 amps at 12 volts. That is about twice the amount it takes to power the 100 watt amplifier in our machine. Originally, it came with a automobile cigarette lighter socket and we just clipped it off and inserted the bare wires into the other components. Interestingly, this indicates you could run this DIY PEMF mat from your car lighter socket but it will really stress your car’s electrical system. We recommend against this without further testing.

 The PEMF Mat

Many DIY devices you see on the internet just use a simple coil to get a PEMF signal. At ElectroMeds, we ALWAYS aim for the top! Likewise, building a mat to test our controller is the only way to go. Also, we want the mat to have some qualities which are not available on other mats.

Most mats fold and still take up a lot of space. We want our mat to be thin and flexible so it can be rolled up. Unfortunately, this creates a problem because the thin copper wire used in PEMF mats can wear out and break. We solved this problem by using multi-stranded and PVC insulated copper wire sandwiched between very thin yoga mats.

The mat coils are wound according to Nikola Tesla’s patent for efficient electromagnetic coils. Also, the coils are wound in a square pattern so the PEMF’s reach the edges of the mat. You can see there are more turns where your feet would go if laying on it. Generally, this is the way most mats are made. Typically, your feet get more free PEMFs from the Earth and most treatments recommend lighter doses for your head. This mat design reflects those observations.

To wind the coils, we calculated 3 progressive lengths of wire and unwound them down our long driveway. Then the first yoga mat was laid out and sprayed with super strong contact cement. Each length of wire was folded double then carefully pressed into place on the tacky mat. Then, the wires were cut and soldered together to make the Tesla style array. Finally, more contact cement was sprayed on and the second yoga mat laid on top. Once the coil ends were screwed into the controller terminals we had a working PEMF machine!

Testing the DIY PEMF Machine

Of course, we used DIY test equipment to test our DIY machine. We found a little DIY oscilloscope online and used that combined with coils from a StemPulse to test the output. Interestingly, electromagnetic waves create electricity just as electricity creates electromagnetic waves. We used that concept and our little test rig to prove our DIY PEMF machine works.

Specifically, we measured for the presence of electromagnetism near and far from the mat. We were able to measure ambient waves and then a much stronger field near the mat. Also, the field extended to the edges of the mat and were quite powerful 7 or 8 inches from the mat. It seems the coil design helped make a robust energy field that may penetrate deeper than first expected.

To conclude, we are very excited for this project and happy to share it. Of course, we have tried this machine on ourselves and it has worked to remove pain from injuries such as sprained wrist and tennis elbow. Conversely, there is more work to do in measuring the output properly and making improvements. Please let us know if you build your own DIY PEMF and what your results are.
