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.....

A 2 Watt audio amplifier made from discrete components. This was one of the earliest circuits...
Here the popular 555 timing IC, is wired as a monostable. The timing period is precise and...
As I`m working from a single power supply and I`m trying to keep the design small, I`ve been...
Use a relatively high-end microcontroller ( Piccolo TMS320F28035, 12-bit resolution, +/- 4LSB...
Right here is definitely an simple VE7GC Popcorn RF preamplifier by Dick Pattinson. The circuit...
Remote tester circuit also resembles the logic of a dark sensor (using BC557) . LDR has been...
Here is the circuit diagram of a simple two transistor alarm circuit that can be operated from a...
This kind of sensor switch is suitable for making touch operated bells, buzzers of small toys...
A wireless interface for your next project Got some wire With a coil, a cap and a transistor, you...
The LTC4251/LTC4251-1/LTC4251-2 negative voltage Hot Swap controllers allow a board to be safely...
4-wire resistive touch screen. ADS7846 interface circuit. ADS7846 analog chip contains electronic...
A1602A 40-pin dual in-line package, the circuit functions as follows: playback preamplifier is a...
