This circuit converts surrounding radio frequency waves to electric power. It can provide 40 Volts at 10 Watts indefinitely. The output power can be improved playing with the antenna. Placing the antenna near large metal objects gives more power. Antenna should be more than 150 feet long wire, placed horizontally as high as you can for best results. The pointing direction also is critical to the output. Keep the circuit as close to antenna as posible. You can also experiment with dishes etc. The circuit also acts as a passive detector. When large metal objects passes the power gets higher. Also its sensitivity can detect energy changes on earth and so it can used as early warning of seismic activity

It appears that antenna placement is critical to output. By constructing many of these circuits and connecting their outputs together, you could produce the energy to power a house. Remember each unit needs its own anntena. The best thing to do is to experiment with diferent lengths and sizes of anntenas. Every place on earth has diferent levels of RF power. Ofcource near large citys or near transmiters where RF is huge on air, the circuit works much better. To get an idea of making the best anntena, Imagine that this unit as an all frequency radio reciever. A very critical point to consider is the earth ground of the circuit which has to be properly conductive. An earth ground should consist of some type of metallic, conductive pipe or rod. Use the earth of your house or buy a new earth ground from the market hammer it as deep as you can for best results.
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.....
