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.....

ICl is a 555 timer running at about 16 kHz. This IC drives Ql, a TIP146, which produces a 12-V...
This circuit is a wireless car alarm system that is built using two circuit modules, namely...
This circuit is design circuit for low drop out charger using a MOSFET as the pass element, but...
This electronic circuit is a video signal amplifier that offers a broad band amplifier with a...
The circuit is able to charge 2. 4V, 4. 8V, and 9. 6V NiCd batteries. The LM317T IC showed in...
This little project came about as a result of a design job for a client. One of the items needed...
The following circuit shows about iButton Electronic Lock Schematic diagram. This circuit based...
In Broadband networking and high speed computing applications, multiple high current, low voltage...
This circuit has can to turn down a light bulb arrives at 100W. If Triac there is tall...
Almost all of the DC amplifier circuits are used as the input stage of the differential circuit....
Circuit using an ordinary digital quartz electronic watch, the lower its crystal welding, as...
Each J202 JFET stage provides up to 180 phase shift by 1 megohm potentiometer control....
