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 circuit is based on the IC1 that is 555, for the creation of alternate flashes from the two...
When the panel isn't generating, the entire circuit is off and there is absolutely no current...
The circuit is built around two power FETs, which are configured as a simple astable...
When power is applied to the circuit, the heater coil in the sensor is energized by the 5-V...
This circuit utilizes the MRF123 TMOS power FET. The MRF134 is a very high gain FET that is...
There is something to be said for the processes of reducing a set of objects or functions down to...
The timer is triggered on the zero crossing voltage pulse. The time constant is determined by...
The Mini 3 digit display aka "DVM-module" (digital voltmeter module) can easily be tuned and...
One interface that is missing in the Lego MindStorms system is an electronic ear. We don`t mean...
The ZN414 is a low cost, single-chip AM radio integrated circuit. Launched in 1972, the part was...
Drive a blue or white LED from a low voltage. Normally, if you want to light up a blue or white...
This machine was near-and-dear to me as it was my first real computer, an Ohio Scientific...
Battery discharge will cause plate acidification, affecting the normal life of the battery. To...
