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 AquaCont is an electronic system witch permits to manage and to monitor most of the...
The circuit can be used in telephone lines for speech activity detection purposes. This detection...
The circuit has two ranges: 10 sees to 5 mins and 1 min to 80 mins. It can be powered by a 9-V...
This peak detector uses a CA3100 BiMOS op amp as a wide-band noninverting amplifier to provide...
Water is a precious resource in many parts of the world, and many people rely on water tanks to...
This is a high-speed control scheme LED display screen circuit theory. Adopt the MCS51 series...
Before we study the working principles of a TV receiver, it is worth knowing a little about the...
All sound effects are generated internally by the HT2884 IC. Power is a 3 Volt battery, but the...
A 2004 Chevy Tahoe that totally lost power. I was driving at 60 mph and watched my tachometer...
This unit is intended to be connected to an existing car stereo amplifier, adding the often...
This design is for PC Soundcards obviously. If you need an interface for a Mac see my other page....
This transmitter is very stable and will deliver up to seven watts of power with the components...
Circuit works: The controller consists of a power supply circuit, a control circuit and audio...
Expressed LM629 PWM outputs directly drive LM18298 dual H -bridge circuit conditions. The latter...
