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.....

The RF circuit is a C-Class power amplifier . it is used in last stage of transmitters .Its...
This 1 square meter antenna has radiation resistance of about 10 nanohoms, making the 0.4 Ohm...
The figure shows two TL3103 linear Hall-effect devices used for detecting the angle of rotation....
A simple bridge rectifier and a 12-V regUlator powers the MOSFET sensing circuit. The unregUlated...
The VLF whistler receiver is intended to listen to natural radio noise and signals that occur...
LED light chaser circuit typically refers to an electronic configuration able to generate or...
What kind of microphone or mouthpiece I can use to connect across a pots telephone line in order...
Designing a circuit that will use a combination of switches and resistors to allow a...
Although the voltage across the two pins of our microphone will fluctuate based on the input...
Darlington connection-type transistor is used for the drive of the coil. As for the Darlington...
Here is the circuit diagram of a very simple wire loop alarm based on a N-channel enhancement FET...
The time can be set with a potentiometer between 1 minute and 1023 minutes, about 17 hours. A...
Circuit from the AD596/597 form a temperature measurement and control instrument is shown in...
