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 amplifier uses a grounded grid circuit with either the Eimac 3CX1000A7 or 8877, ceramic/metal...
The supply receives + 20 Vdc from the rectifier/filter section. This is applied to pins 11 and 12...
If the battery voltage exceeds about 11 V, current flows through R1, D1, and R2. The voltage...
The circuit uses a Hall-effect sensor, which consists of an IC that resides in a small gap in a...
Tl is tuned to converter-output frequency Ul to provide 45-to-50-dB gain, depending on the...
A 7805 can be configured as a constant-current regulator, to serve as an inrush current limiter....
Many antique radios run on batteries. These include tube portables, such as the Zenith model...
This button, with a few hacks, now makes it so we can open up our office with our Nexus Ones,...
A commercial motor controller is more than simply a circuit to alter the speed of the motor and...
To be used with PC connected to video projectors, where the lighting controller may require...
In some places, allowing only a specific direction by the motor running, even when the power...
8 microcomputer data is 8-bit parallel output, in addition to the serial input of D -A...
Band pass filter allows only signals within a certain frequency range pass through rather than...
