#645 – Moving Down The Stack with Scott Williams
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!
