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.....

Electrodes are immersed in an electrolyte that remains level while the sensor follows the tilt of...
This simple mobile voltage regulator circuit may save your two meter or CB transceiver if the...
Analog peak detection is accomplished hy repeatedly measuring the input signal with an a/d...
The wireless light switch circuit described here requires no physical contact for operating the...
This is a design circuit for mass air flow sensor circuit. The mass air flow sensors converts the...
This is some what different concept But here I have used very simple method. Most of people in...
This electronic lighting dimmer circuit is used to control the lamp for arbitrary brightness....
The enable signal for USB chip and GLCD controller were made by PLD decoder from the address...
The LED car voltmeter consists of the filter circuit, voltage distribution filter circuit,...
As shown in FIG by DN-25 IC switching power supply. DN-25 is a monolithic switching power supply...
By the transistor VTi, VT2 composition self-excited multivibrator output signal VT3 put large...
Circuit principle: computers AC power load is large, the use of the current transformer current...
Fig application circuit is a three-phase full-wave six-step driving an open loop motor controller...
This transmitter works in the short waves from 6MC / S to 22MC / S. Coil L1 is the short wave...
