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

Improve the quality of standard TV images - I designed this circuit many years ago, based on the claims that the technique would improve the quality of standard TV images. The circuit adds information to the edges of the objects and was reported to bring out more detail. After building and testing . . . Hobby Circuit designed by David A. Johnson P.E.-July, 2000
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

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
