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 circuit is for a temperature controlled constant current battery charger. It works with...
Using only 2 capacitors, 3 resistors, 4 seven-segment Display, 1 xtal, 2 switches n.o. and 1...
The circuit is powered by the receiver's pack, the current drain is low, specially if compared to...
Here is a circuit for using the printer port of a PC, for control application using software and...
This circuit provides a regulated dc with less than 100 mV of ripple for microprocessor...
This self-starting fixed frequency oscillator circuit gives excellent frequency stability. Rl and...
Using two SCRs, this control circuit is designed to lock out the other SCR when one has been...
Integrated circuit Ul (an NE602 double-balanced mixer) is a combination oscillator and frequency...
Stepper motors, due to their unique design, can be controlled to a high degree of accuracy...
This is a 5Volt to 12Volt DC-DC step-up (boost) converter circuitry with the intention of is...
Current meter used to measure the current from a solar panel. It has very low power loss for...
This electronic rf detector electronic project is designed using common transistors and other few...
This is a single zone alarm - with automatic exit, entry and siren cut-off timers. It will...
The lighting hood of AquaOne AR-320 tank. These small tanks generally come with crappy tubes with...
555 limit when one group integrated electrical circuit load circuit is shown. It can limit the...
