MEP EP#236: Excited Electrons

Parker

  • Lead Forming Topic

    • Tools
    • 3D printed forms
    • Best practices?
  • Cat Feeder Unreminder

    • Choosing a solar panel

      • Solar Panels generally act like a current source across its useable power band
    • Specifications that are important

      • Power (Watts) - Max
      • Current @ Peak Power
      • Voltage @ maximum power point (Vmpp)
      • Vmpp - Voltage @ open circuit (Voc)
    • AEM10941 Solar Panel Chip

      • Max V is 5V so open circuit can’t be higher then this
      • MPP is set by 2 configuration pins
      • Ratio between Vmpp / Voc

Stephen

  • Voltage References and dev boards

    • MCP1501T-20E/CHY
      • 0.1% initial Accuracy
      • Low noise
      • worst case 50ppm across -40 to +125
      • Capable of sinking and sourcing 20mA
    • AD584 Dev board
      • 0.3% initial accuracy for the J version. The K version is 0.1%
  • Linear rail is shitty

    • Got 300 mm of knock off chineasium linear rail
    • Sounds like sand in the bearings
    • Held vertically the blocks get stuck…

Circuit Break - A MacroFab Podcast

Prepare to plug into the world of electrical engineering on Circuit Break - A MacroFab Podcast. Join two adventurous engineers, Parker Dillmann and Stephen Kraig, as they dissect the latest tech innovations, break down industry news, navigate the challenges of DIY projects and engage in compelling conversations with industry experts. Their real-world practical experience fuels their infectious passion and serves as the driving force behind a show that delves into both theoretical concepts and practical issues engineers face. Parker and Stephen speak with fellow engineers, makers, hackers, and business leaders, creating a dynamic space for discussing challenges in the realm of electrical engineering. They unravel the origins of product updates, ponder the lab-to-marketplace journey of technological advancements and reverse engineer the engineering process. They love to speculate about the decisions dev teams have made and boldly offer their own opinions. The show provides a unique window into electrical engineering for recent graduates and current students, who want a sense of what job markets and workplaces are looking for. About MacroFab:This show is brought to you by MacroFab, which provides a platform for electronics manufacturing services (EMS), hardware development, designing and prototyping for individuals, startups, and businesses. Key MacroFab services include PCB (Printed Circuit Board) fabrication, assembly, and testing. Customers can use MacroFab's platform to upload their PCB designs, select components, and specify manufacturing requirements. MacroFab streamlines the electronics manufacturing process, making it more accessible to a wider range of users, from hobbyists to professional engineers and business owners, many of whom Parker and Stephen welcome to the show regularly. About Parker and Stephen:Parker brings a rich background in Embedded System Design and Digital Signal Processing (DSP). His journey in engineering began in 2005 when he hacked Nintendo consoles into portable gaming units. The following year, he pioneered an Atari 2600 video mod, eliminating RF fuzz and producing over a thousand mods. With a background in Electrical and Computer Engineering, Parker’s areas of interest include robotics, microcontroller theory and design, and image and signal processing with DSPs.Stephen Kraig started his electronics career in 2003 crafting musical-oriented circuits. An avid guitar player, Stephen channels his passion into manufacturing audio electronics, including guitar amplifiers, pedals, pro and other audio gear. He has spent close to a decade perfecting his brewing rig to make the best beer possible, often sharing his experiments with listeners. A Texas A&M Electrical Engineering graduate with a B.S, Stephen has served as the COO of William Mathewson Devices. We Want to Hear From You!
