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.....

A complete zero-voltage switch solid-state relay contains an input circuit, an output circuit,...
The amplifier's gain is nominally 20 dB. Its frequency response is determined primarily by the...
In this open-loop design, the detector diode is Dl, and a level shifting or compensating diode...
The schematic diagram come from circuit: Adjustable High Voltage Power Supply 0 to 1000V power...
Using TCM3105 FSK modem chip from Texas Instruments, you can easily build a Bell 202 or CCITT V23...
LED light chaser circuit typically refers to an electronic configuration able to generate or...
This project has been developed together with some other OMs (in particular Marco IW1DGG) in our...
The first part of this paper describes the high dynamic range CMOS (HDRC ®) imager a special type...
Experimenting with a vacuum tube VCO similar to the one in the link below, but with a few...
Now, let`s re-examine the function of the TRIS registers. The TRISA and TRISB registers control...
Circuit principle : the oxygen sensor circuit by the OS-12, DC amplifier IC1, A/D converter IC4,...
Circuit principle: computers AC power load is large, the use of the current transformer current...
Electronic tube amplifier lovers started his art that simple, excellent single-ended Class A...
