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 output cable from my 20 MHz function/sweep generator dangled over the side of the workbench,...
This circuit utilising a 555 timer IC can be used as an alarm system to prevent the theft of...
Sensing short circuits in equipment that performs under water is especially critical, but Fig....
This is a circuit for an electrically operated rolling shutter usually has a standard control...
The circuit is built using ICM7217 integrated circuit, manufactured by Intersil, which contains a...
This oscilloscope clock project uses a PIC 16F876 and a DAC to generate X and Y signals to draw a...
Here is a simple frequency counter designed to monitor the 240VAC mains supply. It as a frequency...
JFET Pierce oscillator will test any crystal from 50 kHz through 25-MHz upper frequency limit of...
Street wear trench pipe installation commonly used Concealed wiring methods. The control section...
DC panel battery is widely used in power plants, substations DC system. To make the current...
Electric water heater temperature control circuit, with water level indication, temperature and...
