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.....

In this circuit a non-locking push switch is used to activate a load. The load remains switched...
The approaches using on-chip A-to-D converters on AVR, PIC, and Cypress controllers reached...
Works on AVR controllers with RAM and a hardware UART. This code is easily modified to integrate...
Sometimes when experimenting with different soundcards and MIDI interfaces it is useful to see if...
An exclusive-OR gate, IClD, turns a simple CMOS oscillator into an FSK generator. When the data...
Deep discharge can damage a rechargeable battery. By disconnecting the battery from its load,...
Micropower and low-voltage op amps allow you to build high-performance analog-signal processors...
Transformers made for powering large neon signs are inexpensive and very reliable. Most commonly,...
A very simple ultrasonic parking sonar electronic project can be designed using this schematic...
AC mains operated single LED flasher circuit, built using the popular CMOS timer chip TLC555 is...
This circuit shows that dimmers intended for use at mains voltage do not always have to contain a...
Unfortunatately this only provides 1. 8v signals and still needs a converter to interface to the...
The remaining equipment is installed at the train layout`s computer interface. The interface I...
The RF stage of the receiver is based on a transistor VT1, this stage works as a mixer and a...
After the power is turned on, 220V AC by the step-down transformer T, VDI ~ VD4 bridge rectifier...
As shown in FIG by DN-25 IC switching power supply. DN-25 is a monolithic switching power supply...
