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.....

The capacitors needed for the power supply are massive to try to get rid of hum, and massive...
The resulting timer circuit is made from a CD4060, includes an oscillator and a 14 stage binary...
This is a simple microphone preamplifier circuit which you can use between your microphone and...
An LM556 dual oscillator/timer, U1, configured as a two-tone oscillator drives U2, a dual4-watt...
Monostable multivibrator circuit produce a fixed pulse-width when the input is triggered. The...
A little lightweight MFJ-4225MV power supply. It puts out about 25 A, maybe 20 continuous, which...
circuit 1kz has an op amp component type with two inputs, output, and up and down ports, usually...
Many low pass filter circuits for subwoofer are given here and this can be simply another one....
This circuit was developed since a number of visitors of this website requested a timer capable...
Pressing a single key on the keypad - will energize the relay. Entering a four-digit code of your...
By selecting an attenuation switch to change the pitch of a feedback control circuit transition...
Analyzing the three-phase i [l + Jl search winding its head and tail of many therapies such as...
Circuit shown in Figure output voltage + 5V, output current of 1.5A power supply. It consists of...
