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.....

When the lights of an on-coming car are sensed by photo-transistor Ql, things get going....
This circuit uses LEDs to display the beat frequency of two-tone oscillators. Only one LED is on...
When power is first applied to the circuit, 02 begins to charge via LED1, R3, and R4. When the...
The SD1143 transistor provides a gain of about 14 dB in this circuit. It uses the fact that a...
Welcome to the weblog where we discuss about electronic circuits schematics, PCB design, diy kits...
This demodulator is suitable for the quadrature phase-shift keying (QPSK) modulator previously...
A simple non-commercial grade multiplexer compatbile with telephones. It will supports 4...
This circuit uses a 1458 dual op-amp to form a radar detector. C1 is the detector of the radar...
The circuit is a standard RC phase shift oscillator using a single bipolar transistor as the...
A band-pass filter is a circuit which is designed to pass signals only in a certain band of...
Many TOPSwitch TOP223 flyback power supply applications require two or more outputs to supply a...
Easy build and use, the general purpose Big LED with SPI serial interfacing. Expandable for...
This simple circuit can be used to activate whatever you like, for example, by connecting it to...
Mullard TCA240 dual balanced modulator-demodulator provides suppression of carrier frequency at...
A cellular rotary phone - the dialing takes forever! And here in Colorado - on a 10-digit dialing...
Fans are hoping to make a high-quality amplifier, but the most outstanding publications published...
