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.....

Here is a simple circuit which can be used for decoration purposes or as an indicator. Flashing...
The second half controls the steering. The mechanical design is a 3 wheeled caddy with the...
This circuit controls the level of a tank using a bang-bang controlled electrical pump. The...
This circuit draws only 4 mA from a 5-V supply while driving a standard RS-232C receiver. The...
Diagram below shows a simplified diagram of the main peripherals present in the 89S52 or 8052 /...
In circuit diagrams given in equipment manuals, voltages at various points in the circuit are...
The circuit was meant to be powered by a power supply, which is why there is no transformer,...
The idea for this crystal tester circuit sprung out of the need of testing a large number of...
This simple AVR Programmer able to transfer hex programs to mostATMEL AVR microcontrollers. It is...
A sample robot, using parts from VCRs and bought only the minimum necessary to make the simplest...
The prototype of Keypad Switch No. 2 was built using only the Stripboard Layout as a guide. So -...
As shown is composed of a transistor relay delay pull circuit. Just power, 16 F capacitor...
Circuit output current capacity and bulk capacitors Cl, and when the Cl o. 7vtF changed when...
Field effect transistor amplifier has fixed bias input source with feedback. Therefore, the input...
