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.....

H-Bridge This circuit drives small DC motors up to about 100 watts or 5 amps or 40 volts,...
This is a very simple, low cost, Hi-Fi quality power amplifier. You can build it 5 ways, like its...
This circuit modulates a light beam with voice or music from the output of an amplifier. If the...
This window comparator generates an output pulse for each event that occurs within a specified...
This transmitter is capable of two levels of rf power. For low-power wireless video, like in a...
Designing Audio amplifier from the scratch using discrete componentsis interesting, as it allow...
FM Radio project detailed here is based on SONY 1619 chip. This is single chip radio means,...
The series of light switches this time slightly different from the stress of work. The series of...
Introduction The ignition Timing lights in common use range from simple neon to complex units....
The LM3361A contains a complete narrow band FM de- modulation system operable to less than 2V...
This is the electronic schematic of the homebuilt SONAR. Only one piezoelectric tranducer is used...
Expensive stereo is general often have VU meter come to and for help show max power the stereo...
The required output at the inverter is 220/230V @60Hz. Basically, let me say i need an inverted...
Your TVT-MOBI-2 will only display this static image and will not yet react to any data received...
As shown for the stable sine wave oscillator circuit. In order to obtain stable oscillation, the...
Figure 1 circuit uses a single +V power supply, and a voltage output DAC AD5620. DAC input by an...
