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.....

Based on the classic Baxendall tone control circuit, this provides a maximum cut and boost of...
This circuit takes standard 0-10V control voltage (for example from analogue light controlling...
You need free power? This schematic transforms the surrounding radio waves to usable current. The...
The input signal is applied through R3 to the inverting input of the summing amplifier and the...
The LED with integrated flasher is connected in series with the base-emitter junction of...
The HA7210 oscillator 10 combines with an IOL7642 quad CMOS op amp to produce a sleep-mode...
This car audio amplifier circuit is based on LA47536 audio amplifier integrated circuit designed...
This relay circuit is controlled by almost any type of infrared remote controller. This circuit...
Electrical lines which include lighting circuits begin from the main distribution panel of the...
The JarLight is a small flashlight based on a white light emitting diode (LED). It is powered by...
Many enthusiasts will be using their PCs as data loggers, controllers or as web servers. ln these...
A servo contains a small motor and gear box that rotates a shaft to a precise location and holds...
Radio FM radio chip circuits use different, it works slightly different, as shown in the use of...
At high frequencies, q, Cz can be seen as a short circuit (i.e. RPi not present), as shown in...
