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.....
.
This is design for a frequency meter based on AVR microcontrollers. Maximum input frequency is...
This circuit uses a low-input-bias op amp to give a steady dc indication of light level. To...
This circuit exhibits a 10 V acquisition time of 900 ns to 0% accuracy and a droop rate of only...
This TMOS VCO operates in push-pull to produce 4 Wot 70 MHz. It consists of two MFE930 TMOS...
ITU-R 468 is a standard relating to noise measurement, widely used when measuring noise in audio...
However effective a domestic alarm system may be, it`s invariably better if it never goes off,...
Here is a very simple three transistor audio amplifier circuit that can deliver 250mW to a 8Ohm...
COMSOL, adding SPICE® elements into its FEM, gives the possibility of a direct modeling of...
This application note describes a driver solution developed using the Zetex ZXLD1362 LED Driver...
This tester is designed to locate stray electromagnetic (EM) fields. It will easily detect both...
TNC and Modems ruled the world of digital communications until recently. With the advent of high...
High quality DAC convertor from USB to S/PDIF. I choose PCM2704 circuit, which sent me TI company...
This is a very simple ring modulator circuit which will allow you to make interesting analogue...
Circuit at rest (dark) state operation the electromagnet M current flows, once there is...
