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 circuit uses a 555 timer in the bistable mode. Touching T2 causes the output to go high; D2...
Designers can build a 15-dB compressor with a miniature lamp and a current-feedback amplifier....
Using an Intersil ICL8038, this function generator generates frequencies from 1 Hz to over 80...
This low-power 25 watt power inverter circuit which makes use of only 9 electronic parts. The...
Figure A is the schematic of the microstrip single stage RF amplifier. The amplifier is based on...
This is a universal 1 Watt RF class C amplifier that is ideally suited for low power FM...
This circuit liquid level sensor is using a simple and common operational amplifier IC 741 used...
Introduction The SP6648 integrated synchronous boost Regulator is a compact circuit that provides...
A PING Ultrasonic Range Finder to build up a system which is capable of detect and measure the...
You might find yourself needing a low power H bridge for driving a motor like I once did. The 555...
I decided to throw together a schematic of how the OEM AUX switch should be wired, and print it...
This circuit runs a fast battery test without the need of power supply or expensive moving-coil...
The simplest inverter to understand is the single-phase inverter, which takes a dc input voltage...
This circuit features an intermittent siren output and automatic reset. It can be operated...
The power supply was built into the base of the mic which can lead to hum issues despite the...
