MEP EP#241: Failing to Electrocute the Chicken

Podcast Notes


  • Bit of feedback on a live stream
    • People suggesting YouTube live
    • Will set this up for episode 242
  • The little things no one sees that make projects take forever
  • 3D printer update completed
    • New fans
  • TI calls for lower-cost sensors to boost robot adoption
    • “We don’t see as many robots as we’d like”
  • Elon Musk’s Neuralink implant
    • Pig example


  • High voltage low current measurement – The circuit evolves
    • Adding resistance measurements
    • The new process
      1. Use the resistor measurement probes to measure the screen resistors values and record those
      2. Use the resistor measurement probes to measure the cathode resistors and record
      3. Plug test harness into the DUT
      4. Begin test
      5. Program will read voltages and using the resistance measurements it will give you a target voltage.
      6. Turn trim pot to set idle current such that the power dissipation is met
    • The load is dynamic and this is an unregulated power supply
  • Looking for bananas
    • Want to have “multi-meter” banana connector
    • History of the banana connector
    • Technically a binding post
