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.....

Like most other ESCs, this one is built up using N-channel Power MOSFET`s because of their good...
This LOGIC PULSER capable of delivering pulses of various compositions, to any type of circuit...
This locater is made up of two parts. The first is an rf oscillator, whose circuit is shown in...
The temperature sensor provides an input to pin 3 of the NE5037 of 32 mV/°C. This 32 mV is the...
The current range in multimeters, particularly the more inexpensive ones, is restricted by the...
This little transmitter is suitable for less demanding Doppler propagation measurements. It is...
Original components, when still good, are stable and not subjected to infant mortality. Of course...
UGN-3501T Hall sensor due to the composition of the counter circuit diagram UGN-3501T has a high...
The system uses optical fingerprint sensor with ARM Cortex M3 core STMicroelectronics 32-bit...
AURA VA50 company is famous for, from about 1989 to begin production (from this point we can see...
As shown, the circuit 555 as the core, and the composition of the photosensitive resistor RG and...
