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.....

Often a need arises for connection of two telephone instruments in parallel to one line. But it...
The intention of the following application shows how the NE5517 works in connection with a DAC....
Transistors Ql and Q2 make up the flip-flop while Q3 drives a reed relay. When power is first...
All the naturally occurring phenomena like sound, temperature and pressure etc, are analog in...
This assemblage was advised for amateurs owning an old accumulating of vinyl recordings and...
When your application requires no PWM (pulse-width-modulated) dimming or controlled frequency...
A TRIAC driver board for use with my reflow toaster oven project, which means mains voltages....
As it has already been stated the circuit consists of an ultrasonic transmitter and a receiver...
This is a "quick-and-dirty" page that I set up to describe the T1-rate modem that I designed...
Each CdS cell acts as a variable resistor in a single variable phase-shift circuit and there are...
The goal of this project was to create a multi-effect guitar processor. This device will be...
The Clearcom type intercom bus runs at a significantly lower level than the Sony bus, the signal...
The UART, or Universal Asynchronous Receiver / Transmitter, is a feature of your microcontroller...
As shown in FIG homemade wireless remote control circuit diagram; A motor remote road works...
Circuit shown in Figure 3-7. Just touch sensor chip (conductive sheet). Eight gear speed can be...
Dispenser (Aucma) temperature detection control circuit It shows the dispenser (Aucma)...
