Using a battery power source the TENS device produces a high voltage but low current signal at a specified frequency and duration. This electrical current is applied externally to the skin of the body using sticky foam electrode pads. The more expensive units have advanced features like dual-channels, programmable functions, a digital readout, etc. They have been around for many years and are

used by doctors, therapists, chiropractors, rehab clinics, college and professional sports organizations and individuals. Anyone seeking relief from muscle aches and pain that does not involve the use of drugs. This article, found on a web site for a company that sells TENS units, provides some interesting if albeit theoretical claims on how TENS devices do their thing. I have no connection whatsoever to this company but it`s worth reading. I found their assumptions to be quite plausable. . I also found some basic guidance about using a TENS unit specifically for RLS at this site:. I am not a medical professional. I am providing this web page for informational purposes only. A TENS unit should not be used by anyone who wears a heart pacemaker or defibrillator. It should never be used about the head or neck. If you have been diagnosed with epilepsy or have been told you are pregnant you should not use a TENS device. If you make or use this device you do so at your own risk and I accept no responsibility for the outcome. I created this web page to try and help others out there who suffer from RLS. In my search for some kind of help I found little serious discussion or useful information on the internet concerning using a TENS unit to relieve the symptoms of Restless Legs Syndrome or RLS. Surprisingly there does not appear there have ever been any credible medical studies of the potential benefits either. I`ve had RLS since I...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
