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.....
.
The circuit has a flat frequency response from about 20Hz to well over 50Khz. Input sensitivity...
The DS protocol was designed to provide firmware-based bidirectional host-to-slave inter...
The resistance of loudspeakers is characterized in a frequency depending on the destination and...
This circuit uses an LED and 4081 CMOS integrated circuit. The variable resistor sets the voltage...
If your ear is good, you can use this IR-pulse-to-audio converter to troubleshoot infrared...
Audio frequency-shift keying (AFSK) is a modulation technique by which digital data is...
The market may be full of these hi-end remote controlled toy cars, but for a hobbyists making one...
This project was completed during a course on robotics taught by Prof. Dave Barret at Olin...
This circuit allows an SPST momentary pushbutton to act as a push-on push-off switch, using a...
This electronic circuit diagram is an audio power amplifier based on TDA8571J integrated circuit,...
Using this schematic electronic project can be designed a very simple water level indicator...
The 4 data lines from the Keypad Interface go straight into the data inputs of the Holtek 9200B...
This schematic shows a peak-reading diode voltmeter driven by two stages of amplification. A 100-...
Electric start and stop the timer circuit diagram shown in the following cycle, LM555 adjustable...
