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.....

This simple Linear circuit provides continuously variable regulated current (~25-400mA) from a...
In microprocessor control of multiple loads, the minimum cost per load is critical. A typical...
U1 is a 4060 12-stage binary ripple counter that is used as a free-running oscillator; its...
The circuit in Fig. 56-lla lights the signal lamp upon detecting a line current consumption of...
This phase-shift oscillator is useful for audio oscillator applications. Adjust R7 for a good...
Tube Distortion Pedal circuit diagram. IC1 : 747 dual op-amp, other ICs may be substitued but...
The technology of range finding employs extensively in civil, industrial fields such as...
The target of this project was the design of a small portable mixer supplied by a 9V PP3 battery,...
The 900 Hz tone is generated with an LC-oscillator. The "L" part of the "LC" is provided by the...
The 8-lead plastic mini-DIP LM3909 IC was developed by National Semiconductor in the mid...
The original firmware is usable on the amateur radio bands, but is not very convenient to use....
As shown in Figure by the built-in temperature sensor to control the triac TC620 achieve...
Specific remote control transmitter circuit composition shown in a diagram. Transmitter mainly by...
As shown in the lock circuit by a decimal counter CD4017 composed by ten its output terminal is...
BKQ series automatic parallel controllers are designed specifically for small hydropower...
Circuit work process is: When the momentary switch S between, since the voltage across the...
