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 ProfiLab-Expert software allows you to develop your own digital or analogue measuring...
In a basic astable timer, configuration timing periods 11 and 12 are not controlled...
The Class A series resonant inverter portrayed is well-known and respected for its high...
Useful for A/B control, the IR receiver shown controls a relay from an infrared beam that has a...
The tester provides an audible indication of the logic level of the signal presented to its...
Designed in the fifties, this pre-amp remained in production until 1975. And, it remains fully...
This is schematic diagram of a video amplifier circuit, built based very high speed opamp IC...

These have two coils and are controlled by changing the direction of the current flow through the...
The aim of this project is to transmit analog sound from a commercial mp3 player digitally using...
These relatively simple circuits can be used to transmit information across a small distance. The...
This application note describes a driver solution developed using the Zetex ZXLD1362 LED Driver...
A simple single-transistor Colpitts oscillator whose schematic is shown in figure 2. When a...
The purpose of this circuit is that of power a lamp or other apparatus for a given time (30...
We added an external piezoelectric element to set on the bench top, making it easier for kids to...
Ic, spread the use of electric comparator LM339c1 / 4), the potentiometer B to set the desired...
As shown in FIG XTR108 four-wire RTD is connected to the circuit. Four-wire RTD lead resistance...
