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.....

Here i propose a project of an AB class power amplifier, at its simplest, assembled with common...
This revision reduced the signal level and treble response in the preamp for a smoother sound...
An op-amp comparator is used to compare the converter output with a dc threshold voltage. The...
Simple high efficiency Colpitts oscillator. In the higher frequency ranges, above 50 MHz,...
To connect two computers or connecting two HUB / switch with UTP cable, can use a crossover...
With the phasing out of game, serial and parallel ports from modern computers and the ever...
This circuit uses the popular and easy to find LM3914 IC. This IC is very simple to drive, needs...
A simple and cheap Laser Based Security System, which costs below Rs. 100. It is a simple circuit...
Drive a blue or white LED from a low voltage. Normally, if you want to light up a blue or white...
This toy traffic signal uses a single low-cost hex Schmitt-trigger inverter IC (IC1a-IC1f) to...
This simple circuit can be used to program the PIC16F84 and similar "flash memory" type parts. It...
The figures(a), (b) are as shown, they are AC measuring circuits. The 21(a) is a current...
As shown for the intensity of reflected light detection circuit. The circuit consists of an...
As shown in Figure 567 FM demodulation circuit. The figure, the FM signal from the input pin 3,...
As shown with the production of hi-fi amplifier IC TDA1521A amplifier circuit having fewer...
