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.....

In this circuit, a TU31 shunt regulator is used to sense the output voltage. The TU31 drives the...
Switching diodes are used to fire the neon lamps when negative-peak modulation hits 50. 60, and...
Generally, during power up of the apparatus, the capacitor is the main reason that surge current...
The filter R1, R2 and C1 integrate the PWM waveform. But what is the point of the op-amp It looks...
It needs 2 volts as its threshold however, that only allows a small amount of curent to flow...
This tutorial is in continuation with previous tutorials on 8051 Assembly Programming. Now we...
This circuit is a Digital Radar Speedometer. It allows us to evaluate the speed of any object...
TLD 5085EJ is a smart LED buck converter with an integrated power switch capable of driving up to...
One can transform an ordinary binary counter, such as a 7493, into an up/down counter with mode...
Also known as digital amplifier Class-D amplifier with small size, high efficiency...
As shown for the basic connection circuit INA326/327 signals and power. Selection of the highest...
Circuit shown in Figure 3-147. To allow sufficient braking time, using the time relay KT (1 ~...
