.Here I will show you how to build your own Tens machine and reduce the amount of pills you use to stop pain .To Build this Tens unit, you will first need to buy a 555 timer IC . The 555 timer is very small about a quarter of the size of your finger nail .You can purchase one for about 25p from Maplins or Radio Shack etc .
There are 2 types of Tens machine. High Frequency Tens uses frequencies in the range of 80 to 100 Hz. This blocks the pain impulses going to the brain .
Low frequency Tens uses frequencies from 2 to 4 Hz . This will help the body produce its own endorphins and increase local blood flow to relieve pain ( this can last for hours ) .
Square waves are universally encountered in digital switching circuits and are naturally generated by binary (two-level) logic devices. They are used as timing references or "clock signals", because their fast transitions are suitable for triggering synchronous logic circuits at precisely determined intervals. However, as the frequency-domain graph shows, square waves contain a wide range of harmonics.

SQUARE WAVE TRAIN
The “Square wave” permits the frequencies to penetrate the body more efficiently at any given Khz output. Square waves are considered the superior “frequency to wave” output for any Frequency generator device.
