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.....

This inverter circuit can provide up to 800mA of 12V power from a 6V supply. For example, you...
The circuit uses a thermistor and three sections of a LM3900 quad op amp IC. When the temperature...
In this application, the timer is connected in the monostable mode. The circuit is triggered with...
Interested in starting an intro electronics project using a IR sensor and am having a little...
Developing a battery switch-over circuit which is made of two lanes of the depicted circuit....
The NiMH battery chemistry is a topic which, for most of us, is shrouded in mystery. Myths seem...
As we presented in another article the A3952S integrated circuit ( designed by Allegro...
A continuity tester is handy for checking that there is an electrical conducting path between two...
As part of the DBS 800 System, this Audio signalling processor will provide an inband Tone...
The TS2418 is a monolithic integrated circuit telephone Tone ringer with bridge Diode when...
Using a single 555 Timer IC and a small transformer to generate a high voltage, this circuit will...
Ultra simple circuit of the tilt sensor alarm presented here can be fabricated using readily...
This little aid was originally designed to test the Shutter Time Meter. This meter was...
The receiving circuit: the infrared signal is inputed to MC3373 from 7 foot by phototube, the...
