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.....
.
Charging current is about 100+mA, which is the internally-limited maximum current of the LP2951....
The present trend is to use ever higher frequencies. But by doing so it becomes more difficult to...
This circuit is ideal for use as an over-under temperature monitor, where its dual output feature...
This detector is useful in sine wave squaring circuits and A/D converters. The positive input may...
Zeroth-order resonant (ZOR) antenna manufactured on microstrip transmission lines has attracted...
This is a circuit of negative resistance circuits. All of the preceding circuits rely on RC time...
ZSSC1856 of ZMDI Company is the double-channel ADC of integrating embedded MCU, made up of two...
The wide-range current pump for the precision phase locked loop circuit is a semiprecision ...
CAD`s original E100 microphone was an inexpensive (for its time) multi-purpose studio condenser...
Most of the peripherals that interface with PC uses USB port. The computers power supply circuit...
A simple and cheap Laser Based Security System, which costs below Rs. 100. It is a simple circuit...
Firecrackers are normally ignited by using a matchstick or a candle. You have to run away quickly...
The design presented here is a little bit unusual in its arrangement, but offers some advantages...
A few time ago I decided to create a media center box to replace my DVD player, sattelite...
The antenna is simply a pair of vertical dipoles. The diodes in each dipole allows the circuit to...
It uses three-terminal adjustable voltage regulator power supply functions and suspension...
