Circuits Designed by Dave Johnson, P.E. :
  • 12V Cooling Fan Thermostat
    This circuit will turn on a 12v DC powered cooling fan when the air temperature reaches a certain high temperature and will keep the fan turned on until the temperature drops below a second lower level.  Both the high and low temperatures are both adjustable.  For ease of use, the temperatures are proportional to either degree F or degrees C, using an accurate electronic sensor.......

AD7416/AD7417/AD7418 Power-On Reset Circuit -  AN-588 Analog Devices Application Notes....[App Note]If a large number of decoupling capacitors are used on  VDD line, re-applying power before VDD has discharged to 0 V can cause  AD7416/AD7417/AD7418 to reset into an unknown. state.
Adaptable Video Thermometer -  The temperature is shown on an ordinary TV with crisp, full color graphics. Animation and sound can be easily added.  Pictures are recorded on a DVD or CD and can be varied according to the application.  Amazingly simple and cheap design (fits a $10 budget). Software tools are free....(added 06/05)
ADC's Reference Improves Rtd Measurements -  10/27/94 EDN-Design Ideas....Temperature measurements using RTDs (resistance-temperature detectors]generally employ bridge circuits with stable power supplies for signal conditioning. Unfortunately, this scheme generally produces nonlinear outputs. A linear bridge configuration that uses two identical current sources depends on  accuracy of matching  sources....
