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 very basic to build. To open a lock which is connected to the K1 Load, you must...
A simple circuit with which we have the possibility opening and closing the RL1 contacts. He...
Here we use the PIC16711. Rechargeable battery capacity is rated in mAH (milliampere-hours). The...
The Visual Target Tracking System (VTTS) is a system for visually tracking targets using a gimbal...
I am not a great fan of novelty radios, but this one looks swell on the wall and doesn`t take up...
Sometimes you have a situation where you have a 5-V supply voltage but part of the circuit needs...
This Resonance generators (oscillating sound generator) circuit, designed using CMOS integrated...
Cigar Lighter Plug to USB Power Socket. This circuit is convert 12V DC source from car cigar...
attribution You must attribute the work in the manner specified by the author or licensor (but...
The MAX1846 inverting circuit to implement a switch-mode power supply that provides a -15V at 0....
This circuit is IC controlled emergency light. This series of automatic switching-on of the light...
This simple circuit can give regulated 4. 7 volts for charging a mobile phone. USB outlet can...
The FX919A is a CMOS integrated circuit that contains all of the baseband signal processing and...
Build a device to determine the depth of the flocculent layer in a lake. The flocculent layer is...
The Frequency instability in VFO stage is a common problem. This is usually occurred in VFO`s due...
Circuits that use a temperature compensating resistor have a small error because the tempco`s...
Electronic temperature control circuit on an imported car air conditioners. Operational amplifier...
