The history banana connectors with Stephen! Then Parker brings up Elon Musk's Neuralink Implant for happy pigs and why projects take forever.

Parker

  • 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

Stephen

  • 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

About the Hosts

Parker dillmann
  Parker Dillmann

Parker is an Electrical Engineer with backgrounds in Embedded System Design and Digital Signal Processing. He got his start in 2005 by hacking Nintendo consoles into portable gaming units. The following year he designed and produced an Atari 2600 video mod to allow the Atari to display a crisp, RF fuzz free picture on newer TVs. Over a thousand Atari video mods where produced by Parker from 2006 to 2011 and the mod is still made by other enthusiasts in the Atari community.

In 2006, Parker enrolled at The University of Texas at Austin as a Petroleum Engineer. After realizing electronics was his passion he switched majors in 2007 to Electrical and Computer Engineering. Following his previous background in making the Atari 2600 video mod, Parker decided to take more board layout classes and circuit design classes. Other areas of study include robotics, microcontroller theory and design, FPGA development with VHDL and Verilog, and image and signal processing with DSPs. In 2010, Parker won a Ti sponsored Launchpad programming and design contest that was held by the IEEE CS chapter at the University. Parker graduated with a BS in Electrical and Computer Engineering in the Spring of 2012.

In the Summer of 2012, Parker was hired on as an Electrical Engineer at Dynamic Perception to design and prototype new electronic products. Here, Parker learned about full product development cycles and honed his board layout skills. Seeing the difficulties in managing operations and FCC/CE compliance testing, Parker thought there had to be a better way for small electronic companies to get their product out in customer's hands.

Parker also runs the blog, longhornengineer.com, where he posts his personal projects, technical guides, and appnotes about board layout design and components.
