#208 - IrriVoyeurism
The Sprinkler Nerd Show
What if you could spy on an irrigation system without ever touching the controller? Welcome to Irrivoyeurism. In this quickie episode, Andy explores how a simple soil moisture sensor can reveal the hidden behavior of an irrigation system—from how often it waters and how long it runs to how quickly the soil dries down between irrigation events. For decades, if you wanted to understand an irrigation schedule, you went to the controller. Now you can go straight to the soil. Because every irrigation event leaves a signature. The soil becomes the diary of the irrigation system, recording what...

#207 - Are You One Of Them?
The Sprinkler Nerd Show
Every episode, Andy ends with the same invitation: "Reach out anytime." Thousands of people have heard those words. Only a handful have ever acted on them. What separates the people who send the email, make the phone call, introduce themselves, or ask the question? In this five-minute Quickie, Andy reflects on a story from Steve Jobs about calling Bill Hewlett at just 12 years old and how one simple question changed the course of his life. The biggest opportunities often begin with a single act of curiosity. Sometimes all it takes is the courage to ask. So... are you one of them?

While listening to Jimmy Buffett's Don't Chu-Know, one lyric stopped me in my tracks: "The best navigators are not quite sure where they're going until they get there." Whether it's an old sailing saying or simply a brilliant lyric, the idea has stayed with me for years. In this short solo episode, I share why I believe the best leaders, entrepreneurs, and even the best versions of ourselves aren't defined by having the perfect plan. They're defined by their ability to pay attention. Life gives us new information every single day....
