this 7805 IC is generally applied to a fixed-voltage of 5 Vdc supply it is for a variable output voltage. (View) This is precision high voltage regulator circuit diagram based 3 terminal adjustable regulator LM317L IC. The circuit require input voltage Vin ‰¥ 178V and can provide output voltage ( V out) between 8 V to 160 V @ 25 mA current output. (View) This split power supply circuit uses the of the popular LM380 audio power amplifier chip. The device is internally biased so that without having any input the output is held midway between the supply rails. R1, that will be initially set to mid-travel, is used to nullify any inbalance in the output. Regulation of Vout depends upon the circuit feeding the LM380, but negative and positive outputs will track accurately irrespective of input regulation and unbalanced loads. The free air dissipation slightly more than 1 watt, and so will require extra cooling. The device is fully protected and will shut-down if its rated dissipation is exceeded. Current limiting occurs when the output current is higher than 1. 3 A. The split power supply input voltage should never exceed 20 V. (View) This Fast response power supply protection circuit is used to protect regulated power supply from the risks of undervoltage and overvoltage condition. When working with a regulated power supply to reduce a supply voltage, there`s always the risk that component failure in the power supply may cause a...
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.....
