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.....

Feedback - This is where part of the output signal is fedback to the input BUT 180o out-of-phase...
Flashing occurs each time the capacitor discharges through the tumed-on SCR. When the discharge...
A pair of timer IC"s are the heart of a circuit that simulates the warbling bee-haw of a British...
This circuit will switch off the line supply to audio or video equipment if there has been no...
How the circuit works is simple when you send a DTMF tone to the decoder the value of pin 15 goes...
A circuit of an off-line telephone tester which does not require any telephone line for testing a...
Most ohmmeters of the design shown in the previous section utilize a battery of relatively low...
A versatile circuit of IF signal generator which may be of interest to radio hobbyists and...
The Keypad must be the kind with a common terminal and a separate connection for each key. On a...
The basic techniques of designing electro-mechanical systems and to gain the knowledge on tuning...
The Intersil ICL32XX devices are 3. 0V to 5. 5V powered RS-232 transmitters/receivers which meet...
The medical ultrasonic atomizer circuit is composed of power supply circuit, on the low side of...
The Amazing All-Band Receiver is basically a diode detector followed by a high-gain audio...
This alarm is designed to sound its Siren only once. That is - when the alarm is activated - the...
Explanation Here is a simple 100-watt using IC CD4047 and IRF540 MOSFET of the inverter circuit...
