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.....

Using the circuit of 40-metre band direct-conversion receiver descr- ibed here, one can listen...
Most operational amplifier circuits require a dual-polarity power supply - one having +V and -V....
To amplify small current signals such as from ah electron-collector inside a vacuum chamber, it...
To generate regulated ± 5-V supplies from a pair of dry batteries, the circuit of Fig. 1 is...
The circuit shown here can be used to control the speed and direction of rotation of a...
The mobile robot should run under the unknown and uncertain environment, must possess autopilot...
This voltage-booster circuit for driving one or more white LEDs uses a 555 timer as its main...
Control a LED with audio signal, but the problem is, that output signal is only 150mVpp (with...
Simple circuit diagram is a schematic remote control, remote control where it consists of two...
This UHF antenna amplifier circuit or UHF antenna booster circuit can be used to amplify or boost...
This circuit allows an ECG signal to be displayed on an oscilloscope. Opamps IC1a, b and d form...
LM35 Smart Heater Controller SchematicMinuscule circuit of the electronic heater controller...
The I2C (Inter-IC) bus is a bi-directional two-wire serial bus that provides a communication link...
The TV-B-Gone is a tiny infrared remote that can turn off almost any TV. A while ago, I ported...
It is possible to build a three-phase sine-wave oscillator using just one UAF42 state variable...
