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.....

Very simple and useful circuit for amplify the stereo signals .The circuit dissipates roughly 28...
Rectified and filtered voltage from the 24 Vac transformer is applied to the LM723 voltage...
In the circuit the frequency trimming component is arranged so that the voltage across it is in...
The telephone ring generator shown below generates the needed high voltage from a simple...
The main system is the user interface and control system. The phone line was chosen as the method...
This is a circuit for an LM1893 power line modem circuit. This circuit is used to transfer...
A timing and counting circuit using integrated circuit chips with seven-segment LED displays is...
This circuit uses12V DC instead od mains AC. This is very good idea if you don`t want to mess...
The infra-red receiver requires the infra-red light to be modulated at 38 kHz, this is quivalent...
100 MHz frequency and period counter using the Intersil ICM7226B 40-pin DIP. This circuit uses a...
