Circuits Designed by Dave Johnson, P.E. :
  • 300V Peak To Peak Signal Generator - This circuit converts a square wave signal to a +-150 volt output signal with fast 100nS rise and fall times. … [Designed by David A. Johnson]  Added December 2007
  • AC Current Indicator Light - This circuit could be wired into a 120vac power line, which feeds power to any load, ranging from 40 watts to 250 watts.  It will turn on a LED light whenever current is being drawn by a load.  It is especially useful for remote lights, where you may not  … [Hobby Corner Circuit by Dave Johnson]  Added December 2012
     
  • Advertising Badge 1 with Flashing LED - I have seen numerous flashing light badges at trade shows and conventions. They are often handed out as gifts to promote some business. The devices often use inefficient circuits, which cause the battery power source to be quickly depleted. My circuit is  … [Hobby Corner Circuit by Dave Johnson]  Added March 2008

  • Advertising Badge 2 with Flashing LED - A single lithium battery will provide months of continuous LED flashing.  It also has a tiny push-button switch to turn on and off the light flashing. … [Hobby Corner Circuit by Dave Johnson]  Added April 2005
