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 circuit modulates a light beam with voice or music from the output of an amplifier. If the...
The ramp generator, an inexpensive alternative to commercial function generators, provides a more...
IC1 is a switching regulator that generates a 45-kHz signal that drives the gate of MOSFET Ql....
This evening as I came home from a paragliding appointment, I had a feeling that I must improve...
The schematic diagram come from circuit: Battery Charger / Power Supply 14V / 4A with MOSFET...
This is a simple microphone preamplifer circuit which you can use betw1een your microphone and...
When 12V DC from the car battery is applied to the gadget (as indicated byLED1) through switch...
This article tries to get you some idea how to interface IR remote controllers to computer....
If you ever thought of experimenting with pulse-width modulation, this circuit should get you...
Because the two amps are the same except for their power sections, we can combine both those...
As shown in FIG constituted by 380MHz RF2175 linear amplifier application circuit. Radio...
Circuit shown in Figure 3-187. When you start, then people start auto ZQB step-down transformer....
Core multi-resonant circuit 40 L06 collapse is 1C.. Auxiliary electric f below its low threshold,...
