Generate composite color video signals in software using an SX microcontroller -  This document describes how to generate composite color video signals in software using an SX microcontroller.  First the document describes the video signal and after that how to do it in software __ Designed by Rickard Gunee

Generate video signals in software using PIC -  During the Christmas holidays 1997-1998, I started on a small project, trying to generate a video signal with a PIC16C84.  I had seen some video clock generating video signals in software, and thought it was a quite interesting idea, and wanted to take it a step further.  I didn't know much about video signals back then, __ Designed by Rickard Gunee

Generating Composite Sync from Composite Video -  The circuit below illustrates generating a single positive pulse which is delayed relative to the trigger input time.  The circuit is similar to the one above but employs two stages so that both the pulse width and delay can be controlled.  When the button is depressed, the output of the first

Generator provides 537 NTSC pattern -  12/03/98 EDN-Design Ideas If you're involved in the television, CRT, or deflection-yoke business, the circuit in Figure 1  can prove useful for adjusting convergence and purity performance.  The circuit generates dots, 537-line- crosshatch, and negative-field(crosshatch- inverted) patterns.  You normally.   File has several circuits, scroll to this one__ Circuit Design by Adolfo Mondragon, Philips Components, Juarez, Mexico

Home Satellite TV System for Less Than 50 Bucks -  Tune into TV signals on the Optus B1 satellite with this surplus gear.  $50 buys you all the bits. __ SiliconChip

Homebuilt Video Digitizer Mark I -  This frame grabber design digitises pictures to very high quality in monochrome (8-bit black & white). Although designed for the European standard 625-line / 50Hz TV system, it should work with the American 525-line / 60Hz standard with minimal modification. __ Designed by W.A. Steer  PhD

Homebuilt Video Digitizer Mark II -  A "video-digitiser" (also known as a "frame grabber") captures television pictures from a TV set, camera, or video recorder, etc., and forwards them to a computer for display, storage, or general manipulation. This document describes a home-built digitiser which interfaces to an EPP (or bi-directional) parallel port on IBM PCs. __ Designed by W.A. Steer  PhD

Infrared Audio Headphone Link for TV -  Do you have trouble understanding what's being said on the TV? Do you need the volume cranked up too loud for everyone else? Do you have a hearing aid as well? If you said yes to any other these questions, here is your answer: an infrared transmitter and receiver to let you listen to the TV sound via headphones.  That way, you can listen as loudly as you like, without disturbing anyone else. __ SiliconChip

LH0032 Video Amplifier -  Schematic Only

Line Cord Resistor replacements -  This page has come about mainly as a result of having open circuit line cord resistors in every single one of my Meck FM converters.  Here, I look at the options for modern substitutes and other schemes for dropping the mains voltage for where a series heater power supply is used.   There is also much misinformation regarding diode and capacitor droppers on the internet, and sadly, some radios are having their valves damaged because of this.  So, I hope to clear this up and show how to calculate the correct components. __ Contact: blehack @ yahoo dot com
