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.....

The circuit consists of a frequency modulated oscillator, an audio preamplifier with pre emphasis...
Full short-circuit and overcurrent protection is given by this circuit suitable for workbench...
Q1 and Q2 are used to form the basis of an interface circuit for attaching a cassette recorder to...
The ac ringing voltage (typically 40 to 90 V at 26 Hz) is rectified by U1, the tone-ringer IC,...
The headlight flasher is nothing more than a 555 oscillator/timer that`s configured as an...
This is a schematic for radio receiver circuit. This circuit is based on the TDA7088T that can be...
This design has not been called a GOLD detector as this name has been left for the more complex...
Barrier measurement of distance method applied is with measuring strength of bound signal....
The cell we will use for our solar tracking experiment is made from crystalline silicon and has a...
This is a simple 12V rechargeable smart battery charger circuit. You can use this best battery...
A couple of few years ago I had build a diode-sensor based RF powermeter using a 68HC11...
Is the battery empty, or is there something wrong with the device That`s always a difficult...
The simplest inverter to understand is the single-phase inverter, which takes a dc input voltage...
The LT3494/LT3494A are low noise boost converters with integrated power switch, Schottky diode...
The Clearcom type intercom bus runs at a significantly lower level than the Sony bus, the signal...
The prototype of Keypad Switch No. 2 was built using only the Stripboard Layout as a guide. So -...
MAX1516 charge pump drives up to 8 from light LED, with a constant current regulation, in order...
