Circuits Designed by Dave Johnson, P.E. :
  • DVD Recorder + TV Camera Make Cheap Data Logger  -  Sometimes recording the results of a test requires as much ingenuity as designing the product. Consider a situation which requires the collection of many different variables over a long period of time . . . [Hobby Circuit designed by David A. Johnson P.E.,  04/01/05]

  • 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.,  07/08/00]

  • Infrared TV/VCR Remote Booster  -  This circuit will boost the signal from any infrared TV or VCR remote, extending the range by a factor of 3X.  . . . [Circuit by Dave Johnson P.E.,  10/05/05]

  • IR TV/VCR Remote Booster  -  This circuit will boost the signal from any infrared TV or VCR remote, extending the range by a factor of 3X.  . . . [Hobby Circuit designed by David Johnson P.E.,  10/05/05]

15 Channels Cascaded MAX455 Video Mux -  On this following circuit shown in the schematic diagram, two MAX455s IC chip are cascaded to build a 1 of 15 video Multiplexer. This cascading is done by connecting the output of one MAX455 MUX to one input of  a second MAX455 MUX. The output of the first MUX should be terminated to ground using a 75R resistor, to preserve bandwidth although the two devices are usually close to one another.… [Designer's name not found]

 

48-Input×16-Output Crosspoint IC Eliminates the Need for Multiplexer Amps -  02/20/03  EDN Design Idea   (Transmission line tests 1-kW device using only 100W) Crosspoint switches are ideal for use in video-security systems, which accept multiple camera inputs while providing playback and multiple loop-through to multiple monitors. To … [by Mike Hess, Maxim Integrated Products, Sunnyvale, CA]
