Meta data for electronic components? Stephen talks about categorizing components to make it easier to get to that part that you really need.

Parker

  • Homebrew going big
    • Uncle runs a brewpub down in Alvin, Tx
    • Going to help him repair and rebuild the brewery for post COVID
    • Building more electrical boxes
  • Chip shortages hit even as auto chip sales climb
    • Ford and Fiat Chrysler are temporarily closing factories due to limited supplies of electronic components that are used in displays and transmissions
    • Apple wants to make a self-driving electric car by 2024
    • VLSI Research report
      • 4th quarter auto chip sales improved by 30% over the third quarter, reaching $6.2 billion
      • Which is 11% above fourth quarter in 2019
      • Overall auto IC sales for 2020 were down about 6.4% from 2019
    • Tesla may be the best example of what happened in 2020, reaching sales of 499,000 new cars in all of 2020, an increase of 36%

Stephen

  • Searching for components kind of sucks sometimes. New idea for making this easier
    • Connectors
    • LDOs and other ICs
    • Simple search removal that doesn’t require that the engineer perform their own logic to reach the “perfect part”
    • No More lists or excel sheets – Savable searches
  • Watch out for datasheet marketing wank…
    • TL052 precision voltage reference circuit
    • MCP1501T-30E/CHY
    • Opamp calls out max 80mA per channel and 160mA per chip…with low offset the best of all worlds!
    • Circuit works well in multiple designs but new one craps the bed
    • Got to pay attention to those charts – this is actually slightly worse than a normal opamp…..
    • Solution is to transistor buffer

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.

Stephen Kraig
  Stephen Kraig

Stephen Kraig is a component engineer working in the aerospace industry. He has applied his electrical engineering knowledge in a variety of contexts previously, including oil and gas, contract manufacturing, audio electronic repair, and synthesizer design. A graduate of Texas A&M, Stephen has lived his adult life in the Houston, TX, and Denver, CO, areas.

Stephen has never said no to a project. From building guitar amps (starting when he was 17) to designing and building his own CNC table to fine-tuning the mineral composition of the water he uses to brew beer, he thrives on testing, experimentation, and problem-solving. Tune into the podcast to learn more about the wacky stuff Stephen gets up to.
