Listen Later

Welcome back, Scott Williams of Xentronics!

  • Scott was on Episode 624 talking to Dave about the business of consulting, but they discussed Scott coming back on to get more into the technical side of things.
  • Chris listened to the episode and wondered if Scott would get more pulled into management of the day-to-day
  • There’s a new program in Victoria (Australia) to enforce deposit/rebates on bottles and cans. This opened up an opportunity for an electronics project.
  • Bin management is another common IoT project
  • Industrial – Site Hive is a long-time customer in the construction space
  • Consumer goods
  • Scott said he’s likely to reach for a Raspberry Pi CM4 for quick prototyping/POC
  • Wht about the high density Hirose connectors?
  • Does Xentronics “go down the stack” by using tools like Buildroot / Yocto?
  • Cameras make products much more difficult. Raspberry Pi cameras have a CSI interface but aren’t “standard” per se.
  • When starting projects, Xentronics is likely to pull out ESP32 for WiFi, Nordic for Bluetooth, STM32 for generic processing
  • Bare metal vs RTOS? Normally they start in the RTOS space to add things later
  • Pre-made / prior art
  • Colin Karpfinger of Punch Through, a firm that largely focuses on Bluetooth
  • EMC resources/courses
    • PCEA educational EMC
    • Todd Hubing
    • Keith Armstrong
    • Ken Wyatt
    • Wurth seminar – Scott never got the recording, but will try again and we’ll update here/reddit if he gets it!
