Video Stabilizer circuit
Have you ever attempted to copy a commercially produced video only to end up with a distorted and jumpy image? If so, then you have run afoul of MacroVision. MacroVision is the most popular copy protection scheme used on the...
Video Clock Superimposer
As a followup to my VCR Pong project, here is a gadget that is actually useful in the Real World! It superimposes the time of day, in "HH MM SS" format, in the bottom right-hand corner of an existing video...
Video Activated Relay
This simple circuit from the May 1996 Think Tank column of Popular Electronics activates a relay when it senses a composite video signal. This allows you to use the tuner built into your VCR to turn on and off older...
5x7 DISPLAY
You must be able to recognise components such as capacitors, diodes, zeners, transistors and resistors to build a 5x7 Display project. This information is covered in our BASIC ELECTRONICS course and a complete set of circuit symbols can be found...

10F15-cascaded-video-mux
Two MAX455s can be cascaded to create a 1 of 15 video multiplexer (MUX) by connecting the output of one MUX to one of the input channels of a second MUX. Although the two devices are typically placed close together,...
monitor splitter
The signal sources in the analog output stage of the PC SVGA card are designed to present the correct impedance of 75 ohms on each line, utilizing five resistors. The input impedances of the transistors are sufficiently high to avoid...
Video Line Selector
When measuring video signals with an oscilloscope, a video line selector is very useful to find a scan line. The line selector generates a trigger pulse at the selected line; the oscilloscope will display only the selected line. This is...
