TV as display terminal interface circuit diagram
The interface circuit is placed between the computer's standard video signal output terminal and the television. It amplifies the standard 1V (Peak-to-Peak) video signal to 3V (Peak-to-Peak). The negative feedback circuit consists of transistors T1 and T2, providing a wide...
A typical laptop power adapter circuit
A typical laptop power adapter circuit converts an AC input of 22V through a rectifier and filter circuit to produce an output of +30V DC. This voltage is then processed by a switch oscillation circuit (U1, UCC38050P), which controls the...
Aladin
Whoever thinks about reproducing an interface for the Aladin should first of all be aware of the fact that there are two different versions of the interface. The first version, easier to assemble, enables the user to transfer dive data...
VGA Hardware Screen Blanker
This design was published in the June 1994 issue of Electronics Australia and has proven extremely popular. The kit was sold by Jaycar Electronics but has since been discontinued. It is a simple device that connects between your keyboard and...
VGA to video converter
The first circuit was utilized to generate a greyscale video, incorporating the composite sync derived from the second circuit. Initial attempts to synchronize the television using only the horizontal sync (Hsync) and vertical sync (Vsync) signals from the first circuit...
C-Bot Article
The schematic is illustrated in figure 10. The circuit can be hardwired onto a breadboard, or a printed circuit board (PCB) can be purchased, as shown in figure 11. The LCD display utilized is a 2-line by 16-character display. An...
Video Fader Circuit
Fading a video signal cannot be achieved merely by attenuating the composite signal, as the synchronization signal may fall below an unacceptable level.
Fading a video signal involves a careful adjustment of both the luminance and chrominance components while maintaining...
video on telephone line wires
The Videowire converts a baseband video signal into a low impedance differential signal that can be sent over ordinary four conductor telephone wire. A send board mounted close to the camera generates the differential signal and a receive board near...
