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.....

This Project can be used with the three phase Induction motors. The circuit will take the full...
This is a lamp timer capable of operating two separate relay switches. Outputs can be in three...
This circuit will convert four-bit BCD into a variable voltage from 0-9 V in 1 V steps. The...
A regulator allows you to power a 7.5-V cassette recorder or other device from a 12-Vdc au
The following picture shows the electrical wiring connection diagram for Honda Motorcycle CB750F....
The circuit in Figure 1 is that of a 4-bit asynchronous counter, also known as a `ripple...
This simple circuit tells you about the status of phone such as Line OK, Dialing and Call...
The thermistor used has a resistance of 15k at 25 degrees and 45k at 0 degrees celsius. A...
The following describes the design, construction, operation and use of the DECUS divider module....
An ultrasonic beacon and a ultrasonic receiver is very similar to a beam barrier circuit, the...
Crystal with small CL(7. 0 pF) makes larger oscillation allowance, smaller current consumption...
This circuit produces the power to drive a bipolar stepper motor. The rotation speed and the...
As shown in Figure as a switching power supply to work with linear regulated power supply. Its...
