Why do I need C1 What does it do I don`t understand their role in the circuit. Why do I need C4 and C5 I don`t understand their role in the circuit c) why doe I need R6 and R8. As for those caps on the power rail, they clean up the signal to make it less choppy so to speak(removing current ripple) you would see this with an osciliscope. The resistors on the bases of transistors

to ground, make sure the the transistors turn off, by effectively removing power to them quickly by draining to ground so the circuit operates quickly.

I`m screaming your praises! WOW! I plugged my TV in and bammo! The picture came on bright and beautiful. What a relief! YOU saved me some money and headache. VM United States I`m screaming your praises! WOW! I plugged my TV in and bammo! The picture came on bright and beautiful. What a relief! YOU saved me some money and headache. VM United States I love this site! $9 instead of a repairman or new/used frig can`t be beaten. This older woman will worry less now that she knows about this site. Bless you all. Windy USA Wonderful service, prompt, efficient, and accurate. Couldn`t have asked for more. I cannot thank you enough for your help. Mary C. Freshfield, Liverpool, UK This expert is wonderful. They truly know what they are talking about, and they actually care about you. They really helped put my nerves at ease. Thank you so much! Alex Los Angeles, CA Thank you for all your help. It is nice to know that this service is...
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.....
