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 version sports a 2nd audio amplifier stage at Q3. The output level with this version is...
A Variable DC Power Supply is one of the most useful tools on the electronics hobbyist`s...
This is a circuit monitoring device. It runs for over 10 days and can log up to 32k events both...
Last year, I found a 31 day pendulum wall clock (dissambled) in a box of parts at a swap meet and...
This receiver uses an IR-sensitive phototransistor (Clairex, HP, etc.) mounted in a light-tight...
Adding a simple clamping circuit to a Harris 2620 high-speed op amp produces a glitch-free...
A very simple low power AM FM radio receiver electronic projects can be designed using the TA8122...
The circuitdescribed herecan be built and used in your vehicle for an automatic dipping and...
The material is presented in a manner suitable for a teaching tool. It seeks to enlighten and to...
A very simple proximity detector can be made using this electronic scheme. This electronic...
PWM waveforms are commonly used to control the speed of DC motors. The mark/space ratio of the...
Voltage-controlled oscillator (VCO) is an oscillator that its frequency is controlled using a...
