This circuit is converter to use to charge DC12V from the lead-acid batteries to AC 250V for use in a car, Boats or mobile homes. There are the output power There are the sufficient power to the small electronics such as a lamp or electrical soldering iron. In circuit use only six transistors, transformer and a few electronic parts. So it is easy

to build and cheap, too. The Q3(BC549) and Q4(BC549) both are the a stable multivibrator (AMV) has output is pulse square wave from about 50 Hz. They will alternately inductor current. When Q3 induct current will have the current flows through Q2, making Q1 connects the half coil circuit of the primary transformer with the 12V drop across voltage from battery. If you use the transistor in the output section to be number: RCA 40411 will be has the current flows through the primary coil in each time is 10 amperes. To power output (Way secondary coil) is 180 watt. However, if the number 2N3055 power output will be have a 90 watt. Because transistors being used in saturation. Therefore, it must be held on a large heat sink. there is the cooling fins that size over than 100mm up and also multiple fins. And If using transformer is triodes core, it makes a smaller size. The circuit is small, because have a little device makes do no adjust to a sine wave. Thus the wave output will be a square. Which may be a result of some electrical appliances, such as, dimmer lights and electric motors, may be will not work. Because it is designed to be used with a sine wave power, and is not recommended for use with color TV and video or audio tape.
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.....
