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.....

One of the unusual features of the out-of-production Programmable Drum Set was its use of touch...
Two 741 operational amplifiers are used for the active element in this Wien bridge oscillator....
The crystal operates into a complex load at series resonance. Ll, Cl, and C2 balance the crystal...
I have been given the following circuit diagram and have been asked to compute R2 and RC such...
2N3819 is an n-channel JFET especially manufactured for RF and mixer applications and provides...
The contact less telephone ringer circuit can produce a ring as well as a visual indication when...
This article explains how to build the second improved version of the HDR-Jack. In contrast to...
This simple power mosfet audio amplifier circuit, with TL071C and 2 MOSFETs (IRF9530 and IRF530)...
Make Z3801A GPS-disciplined oscillators more useful by making 1 PPS and additional 10MHz signals...
This PIC16F84a based repeater (DTMF) controller is very simple & economical to build. It also...
A wireless temperature sensor so that temperature measurements can be made anywhere within the...
The example circuit is for an automatic animal feeder. When the animal pushes the switch the...
In order to accomplish this my initial thought is to sample an input (ADC) at consistant time...
A simple digital circuit is shown can be used to precisely control the AC power supply, the...
Because the loop gain of the amplifier OP depends mainly on the dry input resistor and feedback...
