Hey another cool thing I found is that if you earth both the earth of the circuit to ground and the other end of the antenna to a separate ground, you increase the power dramaticaly, compared to using a normal antenna and coil. I made a similar coil to the one mentioned on the ambient power web page but it didn`t help. I have tested and found that

the power output is greatly related to how large your capacitors are and how well grounded your antenna and circuit grounds are. A metal stake shoved in the ground provides a reasonable ground. But I found that it is much better to get the largest surface area of metal in contact with the ground as possible. I even tryed digging a hole and planting aluminium foil sheets in the ground. That worked quite well. At the moment I am using the earth of the house for the circuit earth and a metal fence for the antenna earth. This is working great. So far I am using 470uF capacitors and IN60 germanium diodes as they have a low voltage drop and the capacitors collect more current compared to 47uF. I also replaced the 0. 2uF capacitors in the original diagram to 47uF capacitors aswell. I also intend to replace them all to much higher capacitor values. Although the mentioned 50-500 farred capacitors on the web site cost a fortune as each one costs $1000+ each and I would need 12 of them. The first circuit showen on the web page that had the problem with the diode, I fixed and is running quite well. I have included a picture of the fixed circuit in this e-mail as an attatchment if you would like to have a look at it. If you have a look at the circuit you will see that it is the diode in red that has been fixed. This circuit has been test run with a computer program as well as practicaly. An example output of current and voltage...
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.....
