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.....

Capacitor C1 is charged through timing resistor R1 when the clock output is high. When C1...
One of the most interesting shield that you can mount on the Arduino platform is certainly the...
Q1, Q2 & Q3 form a high impedance super-Darlington that drives the relay, amplifying the 50 or...
This circuit is conventional Pierce type oscillator that uses a JFET. The circuit uses...
This circuit controls resistive and inductive loads up to 2, 500W. It`s main functional device is...
This metal detector using CS209A made by Cherry Semiconductor. The CS209A is a bipolar monolithic...
A simple calling bell circuit that can be used in small offices to call the office boy using an...
We use the L293D H-Bridge to operate a 12VDC motor with the Arduino. This H-Bridge allows us to...
Some 20 years ago it was common to see small key-holders emitting an intermittent beep for a...
This circuit can be used from low frequencies to at least 120MHz using series resonant crystals...
One of the simplest ways to make a battery powered High Voltage power supply is to use a common...
Circuit shown in Figure 13-4. It uses triode control. Two transistors VTi, VTz by capacitive...
Due to the amplifier frequency characteristics and impact of parasitic capacitance, to make...
