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.....

There are many ways to create a stereo effect. If you were miking a piano, a string section, or...
This is two three pole bandpass filters with the HPF Fo about 50Hz and the LPF Fo about 15kHz....
One of the unusual features of the out-of-production Programmable Drum Set was its use of touch...
This circuit produces the famous Big Ben sound. It produces the "ding dong" sound when switched...
The turn-on and turn-off characteristics of two complementary transistors can be combined to...
This circuit monitors car battery voltage. It provides an indication of nominal supply voltage as...
This circuit holds on the internal light for approximately one minute after the car doors are...
In this circuit, CI is charged to a fixed reference level, then discharged. Integrator ICl...
As you see in the circuit above the four pins "Controller pin 1", 2, 3 and 4 will control the...
The TPA2011D1 is a 3. 2-W high efficiency filter-free class-D Audio Power Amplifier (class-D amp)...
Since then NL has evolved into the Microsoft Windows ®-based NL4, which has been used extensively...
UGN-3501T Hall sensor due to the composition of the counter circuit diagram UGN-3501T has a high...
Motor winding is delta transposition capacitance cl -C -3G DC Lan speed generator and three-phase...
Each J202 JFET stage provides up to 180 phase shift by 1 megohm potentiometer control....
