MEP EP#124: Letting The Loaf Out

Podcast Notes

  • Parker
    • MAX6682 breakout board to read the thermistors
    • Engineer Spotlight on All About Circuits
    • Ford Climate Controlled Seat Module Breakdown
      • Peltier setup
      • Temperature feedback is via thermistor
        • 54K to 240K with the resistance around 170K at room temp
        • Possibly a NTC 200K?
      • Fan uses a LB11988HR from OnSemi
        • 3 Wire
        • Interesting setup to control the speed of the fan
        • What part is Dpak with marking 065886A
  • Stephen
    • The uTracer 3 design update
      • Full on scope creep
      • Adding a STM32 mcu to control the relays to make it “safe”
  • Rapid Fire Opinion – RFO
    • Digital circuits: Now with more analog!
      • Using memristors as data storage devices
      • Two memristors into the output totem-pole of a classic CMOS converter, between the usual p-mosfet and n-mosfet – effectively adding a potentiometer, whose wiper is the inverter output
      • Buy memristors?
    • Interviewing engineers? Should you bring your project or not?
