Prototype Update: From Idea to First Build
A behind-the-scenes look at bringing Beacon Buddies to life
We're building the first Beacon Buddies prototype — a physical button with lights and sound that rallies the neighborhood. Here's a look at our design decisions, technical challenges, and what's next.
When we first described Beacon Buddies to people, the response was almost always the same: eyes light up, a smile, and then "Wait, that doesn't exist yet?" That reaction is what fuels us. The idea is simple and resonant — a physical device that lets kids signal the neighborhood. But turning that idea into a real product involves more decisions than you might think.
The Core Design Principles
Before we wrote a line of code or ordered a single component, we established three principles that guide every decision:
Kid-first interaction. A child should be able to use this with zero instruction. One button. Obvious feedback. No screens, no logins, no complexity.
Impossible to ignore. When the beacon goes off, you notice. Bright lights, a fun sound, visible from across the yard. This isn't a subtle notification — it's a rally cry.
Built to last. This device lives in kids' rooms, gets dropped, gets rained on, and gets pressed ten thousand times. It needs to be tough, reliable, and fun to use on day one thousand as much as day one.
The Hardware
The current prototype centers around a large, tactile button — satisfying to press, impossible to miss. Surrounding the button is a ring of addressable LED lights that can display different colors and patterns. A built-in speaker provides audio feedback: a distinctive sound when you press your button, and a different sound when someone else's beacon activates. We're exploring mesh networking for device-to-device communication within a neighborhood.
The Software Challenge
The biggest technical challenge is reliable communication between beacons. We need something that works without WiFi (not every family has it, and we don't want to depend on internet infrastructure), covers a reasonable neighborhood range, and uses minimal power. We're exploring several protocols and will share more as we narrow down the approach.
What We've Learned So Far
The button matters more than you think. We tested several button types, and the tactile feel makes a huge difference in how exciting the device feels. A mushy button kills the magic. A crisp, satisfying click makes every press feel like launching a mission.
Sound design is critical. The sound the beacon makes needs to be fun but not annoying — because parents will hear it dozens of times a day. We're working with sounds that are exciting for kids but don't trigger parental rage after the fiftieth activation.
Kids are the best testers. Every time we put a prototype in a kid's hands, we learn something new. They find edge cases we never considered, suggest features that are brilliant, and give brutally honest feedback about what's fun and what's not.
What's Next
We're working toward a functional prototype that we can test with a small group of neighboring families. If you're interested in being part of early testing, sign up for our mailing list. We'll be sharing more updates, build photos, and design decisions as we go. This is a community-built product, and we want your input every step of the way.
