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.....

Antenna is the means by which a wireless operator puts his signal into the space and also through...
Room temperature plays a vital role in determining human thermal comfort. This digital...
This circuit turns on a relay when two buttons are pressed at the same time.The relay backs off...
This circuit converts frequency to voltage by taking the average dc value of the pulses from the...
A lot of FM transmitter circuits have been already published here. This just another one, a...

Q1, Q2 & Q3 form a high impedance super-Darlington that drives the relay, amplifying the 50 or...
This handy circuit can be used as a speed controller for a 12V motor rated up to 5A (continuous)...
Sun tracking systems are very effective in increasing the efficiency of photovoltaic (PV) arrays,...
Fly back transformers are commonly found in television sets and can put out 50, 000 volts, enough...
The circuit diagram of the non-contact voltage detector is shown on the figure 1. It consist of...
Circuit works: 220 V AC by C1 Buck, DW regulator, VD whole stream, C2 filtered output 12 V DC...
As shown in FIG relay the delayed release operational amplifier circuit. When the power switch,...
Dual power for each complex since load is supplied by means of two-way power Meanwhile, when the...
