#185 - The Power of NOT Knowing
The Sprinkler Nerd Show
TXT Andy and say what's up? 208 908 3229 -- Hey friends, welcome back to The Sprinkler Nerd Show. Today, I want to take you down a slightly different path. This one’s not about technology. Not about sensors. Not even about irrigation. It’s about something more fundamental… something that shapes how we lead, how we teach, and how we grow. It’s about the power of not knowing. Have you ever noticed what happens when someone asks you a question? What do you do? You probably give them an answer. That’s what we’ve been trained to do. We associate knowledge...

#183 - For Immediate Release, Patent US3808385
The Sprinkler Nerd Show
For immediate release—breaking news, kind of. In this solo episode of The Sprinkler Nerd Show, Andy dives into what seems like a revolutionary product: a mechanical rain sensor that requires no batteries, no Wi-Fi, no firmware updates—just pure, functional design. It shuts off irrigation during rainfall and turns it back on when conditions dry out, all thanks to hygroscopic discs that expand and contract to trigger a simple switch. This device sounds like the newest drop in water-saving technology—until Andy reveals the twist: it's not new at all. In fact, it's based on US Patent...
