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.....

The use of power MOSFETs allows a direct interface between logic and motor power, which permits...
A JFET (Ql) serves as the oscillator. D2 helps to stabilize the transistor by limiting positive...
Display interface uses the ICM7218A/B with an 8048 family microcontroller. The 8-bit data bus...
IR remote control is a device you can find everywhere where you can find TV, VCR or home theatre....
Today we discuss about a simple solar LED circuit. We know that solar panels comes from 12Volt...
Designing the target designator on the basis of MSP430F149 one-chip computer, in order to meet...
Burst Mode operation maintains high efficiency at light loads by reducing IC quiescent current to...
Initially I chose another infrared sensor for test, PIR Motion Sensor, which was to detect any...
This is a design circuit for converter that using for a very practical LM2623A ratio adaptive...
The program uses two pulsewidth variables, pw1 and pw2; and two sets of routines, left1 and...
The USB(Universal Serial Bus) specification provides the ability and energy. This change...
Timer circuit has been used in many projects and there are basically 2 types that are used these...
Software such as that available on PGM-Fi. org and from Hondata make use of the Honda ECU`s...
Whenever there is a need for battery-powered lighting, like for camping, solar powered cottages,...
By using the reverse binary counter and the binary-coded decimal decoder can obtained the step...
Measuring the radiation can be made not only with expensive factory-made instrument. The simplest...
