EP#124: Letting The Loaf Out

• 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"
• 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?
