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 simple and inexpensive circuit can produce a dual (positive and negative) voltage from a...
Just the solution for AVR applications in which I/O is tight, such as the ATtiny12. This should...
A simple, low component count phase locked loop that locks onto and detects the amplitude of an...
Typically, most japanese motorcycles do not have any charge control lamp at all and even on bikes...
The project I present here is my attempt at a universal QRP T/R switch. The idea is to take care...
This circuit has an adjustable output timer that will re-trigger at regular intervals. The output...
The input impedance of a. c. -coupled op amp circuits depends almost entirely on the resistance...
This is a aerial affection ability accumulation with a continuously capricious stabilised...
As part of the DBS 800 System, this Audio signalling processor will provide an inband Tone...
A rear fog lamp has been mandatory for trailers and caravans in order to improve visibility under...
NS LM4766 US company launched a two-channel power amplifier integrated circuits, each channel on...
As shown in FIG Xin US recorders automatically circuitry. The circuit mainly uses a new power...
Cats are predators of rats, the use of electronic devices to simulate mew Repeller is an...
Circuit shown in Figure 13-4. It uses triode control. Two transistors VTi, VTz by capacitive...
