Hi! I made an opamp hartley oscillator using a certain electronics simulator and even though simulation takes place I`m unable to get any oscillation.... -
amplifier input and output impedance, load and source resistance are strongly mutually dependent in the CC circuit. That`s a reason, why "impedance matching" doesn`t achieve results representative for the circuit operation. Analyzing the circuit as CB with.... -
A low-distortion Meacham-bulb-stabilized Wien-bridge oscillator is used to acquire the FFT of a pure sinusoid of about 5 kHz.... -
The Wien-bridge sine-wave oscillator uses a light bulb to stabilize its amplitude. The circuit in Fig 1 doesn`t have a light bulb; it sports several enhancements that lower its distortion and generate a test signal pure enough for testing modern op amps and.... -
Feedback Oscillator Positive feedback is used in oscillators to maintain running or oscillating. An oscillator is basically an amplifier which has a feedb.... -

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.... -
