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.....
.
Connect two 24 V / 3 W bulbs in parallel to the output and set the right frequency on PLL. Now...
Circuit oscillates because the transistor shifts the phase of the signal 180° from the base to...
This circuit puts out a pulse when an object on the conveyor belt blocks the light source. The...
Tl is tuned to converter-output frequency Ul to provide 45-to-50-dB gain, depending on the...
This is a circuit of a microcontroller AT89S52 thermometer and LTC1298 12-bit ADC, programs...
Switching regulators work by drawing small amounts of energy from the input source and...
The circuit shown here is used to switch on a lamp when the tele- phone rings, if the ambient...
Note how the output letters of the integrated circuit [Output A] match with the Diode letters in...
Some circuits need a negative supply voltage that only has to supply a small current. Providing a...
After some years i started using the NMS8280 again for HAM radio purpose. When sending a signal...
This is one way of generating an intense magnetic pulse. A charged capacitor is discharged...
Shows a 32.768 kl-b: micro-power clock oscillator circuit, and can be used in mobile phones,...
By BH-SK-I produced non-contact infrared lamp switch circuit shown in Figure 3-42, it is mainly...
