At the 20250109 ROS Lawn Tractor Meeting, we gathered to discuss the latest advancements in lawn tractor technology and exchange valuable insights on maintenance and usage. Our team was excited to collaborate with industry experts and fellow enthusiasts in exploring ways to enhance our lawn care practices.

Introduction

We recently attended the informative and engaging Lawn Tractor Automation meeting, where we delved into fascinating discussions about powering Raspberry Pi devices. Throughout the meeting, Jeff and Al particularly stood out with their invaluable insights and experiences. Let’s take a closer look at the key highlights from the event.

Powering Raspberry Pi Devices: Insights and Recommendations

• Jeff’s Power Supply Negotiation Stories

  • Jeff regaled us with anecdotes about the challenges and triumphs of negotiating power supply requirements for the Raspberry Pi 4, sharing valuable lessons learned along the way.

• Al’s Booting Tips and Recommendations

  • Al shared essential advice on the initial booting process, emphasizing the importance of starting with an official Raspberry Pi power supply instead of relying on battery power.

• Exploring Raspberry Pi Variants

  • The video index provided convenient links to meeting videos discussing various Raspberry Pi units and their unique features. We learned that some boards have “partial” schematics available, and the existence of multiple revisions of the Raspberry Pi 4 boards.

• Advanced Techniques Unveiled

  • Al demonstrated the intricacies of reprogramming Teensy 4.1 without the need to remove it from the board, showcasing a cutting-edge radio control PCB. Jeff recommended exploring the use of Raspberry Pi 5 with a Raspberry Pi 4 power supply to simulate scenarios without PD negotiation.

• Crimping Vs. Soldering: The Debate

  • Engrossing discussions revolved around the pros and cons of using crimp-on ferrules versus soldering techniques. Attendees shared their experiences and insights, shedding light on the best practices in this domain.
