The South Africa company, which has developed the 5 kilowatt Fuel Free Generator, has discovered that the batteries` longevity is significantly effected by the process. As far as the choice of batteries to test is concerned, there are many different lead acid batteries, Gel Cells, Car Batteries, 2 volt batteries, 6 volt, 12 volt also NiMH or other

types of home made battery. If the batteries stay charged while you are discharging 30 amps through the load, & each of the 6 batteries only receives 10 amps charging current, where does the 20 amps free energy come from. - To achieve a maximum switching speed of 2857 Hz, the opto isolator has to be driven harder to make sure that the gate turn off voltage falls below + 2 volts. There is a 470K variable resistor in the 555 astable circuit which can be used to adjust the frequency to some extent but its main purpose is to maintain a 50 % duty cycle. The square wave cycle time is 350 micro seconds, the mosfet on time will be ( 175 micro seconds - a dead time of 40 micro seconds ) = 135 micro seconds of on time. If you want to eliminate the reduced power output issue, you have to increase the load current to take into consideration 1/4375 of the mosfet on time has been lost. The output voltage from the tesla switch cannot be guaranteed due to the need to reduce the switching frequency considerably when the batteries become charged, thus the dead time will be removed periodically. Lowering the power consumption of the drive circuits means that smaller batteries can used to build portable free energy devices & there is less instability & stress on the toroid which is used to create the isolated 12 volt supplies. Thats the switching part of the circuit designed & tested, now the construction begins. - This is a big project & has...
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.....
