Korean Farmer Tech

With the April NFC rollout fast approaching, I’ve finalized my backend hardware strategy. The focus is on two things: rock-solid data integrity and a sustainable development environment. Odroid M2 (The Powerhouse): The unit inside the wooden box in the photo is the M2 . As my flagship, I’ve equipped it with a 1TB NVMe SSD to handle the main beekeeping database. It features an automated backup system to ensure our vital records are never lost. This will be the central hub for all my future development projects. Odroid N2 (Versatile Secondary): The N2 sitting outside the box is designated for lighter tasks and secondary program development. It provides a stable, isolated environment for testing new logic without putting any load on the main M2 production server. Odroid C5 (The Testbed): The newly added C5 is my dedicated testing and prototyping edge device . Paired with a GPIO expansion breadboard and various sensors, it serves as my "lab" for verifying real-time data col...

  Intro: The Learning Never Stops I recently had the chance to attend the "Future Agriculture Response Workshop" in Jeju. As a "Young Start-up Farmer," getting out of the field and into these innovative spaces is always a massive wake-up call. My mission for this trip was clear: look past the flashy, expensive tech and find the true pragmatism that makes smart farming actually work for real people. 1. WangPang Farm: The Masterclass in "Budget-Friendly" Innovation Walking into WangPang Farm was, quite frankly, a shock to the system. While I couldn't snap detailed photos due to security and on-site conditions, what I saw there was a 100% match for my own vision. The On-Site Insight: Instead of multi-million won proprietary hardware, they built their entire automation system using affordable, off-the-shelf sensors and the open-source platform Home Assistant . It was seamless, powerful, and most importantly, accessible. The Essence of Tech: It proved ...

  The Vision: Why Data is the New Gold in Beekeeping Throughout this series, we’ve covered the technical "how"—from NFC handshakes to the Razor Hybrid UI. But the real magic isn't in the tag itself; it's in what happens when the data starts to talk. As we wrap up this initial journey, I want to share a glimpse of the roadmap that transforms a simple mobile log into a sophisticated agricultural ecosystem. I’m keeping the core engine under wraps for now, but here are some possibilities that open up when every hive has a digital identity. 1. The Command Center: A Unified Ecosystem A smartphone is great for the field, but a professional operation needs a high-level view. I am envisioning a Desktop Control Center (WPF) that goes far beyond simple data mirroring. Native Desktop Synergy: Bridging the mobile experience with a robust desktop environment allows for a "Control Center" approach. It's about seeing the "pulse" of the entire apiary on a si...

Theory Meets the Real World Now that the app's core logic is stable, it’s time to talk about the physical side of things. In development, we often think in "ideal" terms, but the apiary is far from a controlled environment. Currently, my apiary is tucked away under heavy insulation blankets to survive the freezing winter. While a full-scale rollout has to wait until the spring thaw in March, I headed out to the field with two smartphones—one to run the app and another to capture the process—to demonstrate the installation on my EPP (Expanded Polypropylene) hives . 1. The "Golden Spot": Rear-Side Tagging In my apiary, EPP hives make up the majority of the units. I’ve decided that the rear of the hive body is the "Golden Spot" for tagging. Why the Rear? : Beekeepers work from the back to stay out of the flight path. Tagging here allows for an immediate digital record the moment you finish an inspection. Permanence : Unlike covers, which get swapped, the...

  Nature and Health: A Lessons in Patience I was hoping to return with a more technical update this week, but sometimes life—and nature—has other plans. I am still in the process of recovering from the illness I mentioned in my last post. To be honest, I haven't been able to touch a single line of code or make any updates to the app this past week. My priority has been simply getting my strength back. 1. The Winter Silence The apiary is currently buried under a blanket of snow. In this sub-zero weather, the bees are in their winter cluster, and the hives are completely wrapped in thick insulation blankets to keep them alive. As you can see in the photo, the hives are inaccessible. These blankets will remain on until at least early March . Even if I were feeling 100%, physical field testing—like attaching NFC tags to the rear of the hives—is effectively on standby until the spring thaw. 2. The Ideal Spot vs. The Current Reality In my mind, I’ve already decided that the rear of the...

 A Sincere Apology for the Delay First, I want to apologize for missing my scheduled post last Wednesday. I’ve spent the past week battling a severe illness that kept me completely away from my computer. It was a tough reminder that health truly is wealth. I’m finally back on my feet and excited to share the next chapter of this project. Stay healthy, everyone! In this third installment, we dive into the "brain" of the app: NFC communication. I’ll also discuss a major architectural pivot I made mid-stream that completely changed the trajectory of the development. 1. Taming Android's Core: Intent and NFC Adapter While .NET MAUI provides a cross-platform framework, controlling hardware like NFC requires deep-diving into Android’s native APIs: NfcAdapter and Intent. The first hurdle was configuring the MainActivity to intercept the OnNewIntent broadcast whenever an NFC tag is detected. The goal was to make the app react instantly. Getting this "handshake" right, wh...
