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.....
.
Each of these ways have their own advantages and disadvantages. The multiple transformer way is...
This circuit is intended for children fun, and can be installed on bicycles, battery powered cars...
The output of the amplifier is to be measured on a digital voltmeter. Besides being able to...
Have you ever attempted to copy a commercially produced video only to end up with a distorted and...
IC-1 and the associated circuitry form a stable audio tone generator that feeds a buffer...
The employment of the circuit IC1 which build survive astable multi vibrator circuit....
the moving message will be display on the LCD which will be controlled through microcontroller...
It is based on the Miller solar engine and has no digital electronics involved. But before we get...
This sign I designed uses no microprocessor. It has an eprom and multiple counters. As in most...
A car stereo amplifier circuit using TDA2040 is shown here. TDA2040 is a monolithic integrated...
This heat detector alarm electronic project is designed using the UM3561 sound generator circuit...
The adjustment control for the contrast of an LC-Display is typically a 10-k potentiometer. This...
This schematic is a tone transmitter. For sufficiently small values of the resistor, it outputs a...
The device emits ultrasonic sound waves that sweep between 65, 000 and 25, 000 hertz. Designed...
AN6657 is a 16-pin dual in-line plastic package, AN6657S 16-pin dual flat plastic package. 1....
A pulse booster circuit When you need to increase the pulse amplitude, pulse boost circuit can be...
CA3600E array transistor pair and a reverse CA3080 operational amplifier used in conjunction to...
