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.....

Pure A class is the most simple topology for designing an amplifier! The tube or the power...
RF based Automatic meter reading, or AMR, is the technology of automatically collecting data from...
The VTG-01 is designed to display user defined text over a composite video signal. This is useful...
The choice of material to read or drive is the definition of three digits (Bit), RA0, 1,2 PORTA...
By coupling two back-to-back diodes in series with an ac power circuit, a voltage of about 1.4...
This option has the advantage that one does not need to change anything in the receiver itself....
In few previous post, I showed schematic for interfacing Keypad and LCD using 8051 architecture....
This report entails the details on the principles and operation of an amplifier known as the Wien...
The schematic shown here is a circuit of a 555 tracking transmitter. 555 is a famous versatile IC...
WSH412 is designed to integrate Hall Sensor with complementary output drivers and frequency...
The circuit is a precision integrated temperature sensor type LM35 (IC1), which provides an...
It is a resistance tuned oscillator covering from 35 cps (frequency unit was the cycle at this...
Focus on measuring low-level, HF circuits with a return loss bridge ” topics such as using the...
This negative oxygen ion generator circuit is composed of power supply steady voltage circuit,...
The helium-neon laser requires two voltages: a voltage in the range of 10 kV that starts the...
It is a measurement circuit, when the force is 0 ~ 1500g time. U. Output O ~ 1500nN (sensitivity...
