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.....

It's basically a photovore with a couple tactile sensors. It's rather complex but can give neat...
This circuit functions as a line-current sensor and can be connected in series with either of the...
This low cost, crystal-controlled oscillator uses one TTL gate. Two factors ensure oscillator...
This circuit is based upon the change of frequency of the function generator with the input...
A very efficient buck boost converter circuit is shown here. The circuit is based on the LTC3440...
Diagram below shows a simplified diagram of the main peripherals present in the 89S52 or 8052 /...
The following circuits are presented in a logical order (unlike the way they were designed) from...
There is one class of filter called "all-pass" that does not affect the response, only phase....
This is a simple 12V rechargeable smart battery charger circuit. You can use this best battery...
The Muntz one-tube design can be considerably improved by adding an audio preamplifier stage....
This be mini size power amplifier 2 watt OTL that use IC LM380. Be base readymade circuit for...
Interface the ds1820 to microcontroller. As you can see the first pin is connected to GND, the...
Changing to a 3-prong AC cord is pretty much an expected upgrade or mod, as is replacing the...
Generates force field of high-intensity sound inside car, painful enough to discourage thief from...
The operation control circuit mainly by the button switch SB21. Contactor KM1 composed contactor...
A sense of three-point oscillator, also known as Hartley oscillator, the Colpitts oscillator with...
AC solenoid DC circuit operation DC operation AC contactor circuit on the same principle, but the...
