The modules described in this application note can be used as stand-alone multiplexers for both NTSC/PAL broadcast and any HDTV format applications. In addition, by virtue of their size, their performance and the SIP pin outs, they may be used to form.... -
The GT4124 is a broadcast quality monolithic integrated circuit specifically designed to linearly mix two video signals under the control of a third channel. Referring to the Functional Block Diagram, the input signals are applied to conventional....

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.....
Vacuum Tubes 807 and 1625 are commonly used by hams as power amplifiers. Both tubes are audio...
Mains frequency is pretty stable and it is unlikely that you have to measure it but if you have...
The frequency covered is from 0.1Hz to 10Hz and useful signals are received up to 16Hz. The first...
This is basically a flasher circuit modified to turn on and off a bulb instead of a LED. It uses...
The composite input signal is preamplified by transistor Ql and is then coupled to the high-pass...
This is the schematic of a simple 40W, 12 to 220 V inverter. You don`t believe, this is simple...
To activate the air muscle, valve labeled #2 is opened. This causes the air muscle to contract....
The TDA8581(T) from Philips Semiconductors is a 1-watt Bridge Tied Load (BTL) audio power...
The gap between TTL graves and the PC can be perfectly filled with modern microcontrollers. They...
This kit is based upon an original design by Jan G0BBL and provides a multi-faceted replacement...
