🗝️ A Smart AI Keychain With a Personality 👀 1. What I want to build I'd love to build a small, interactive smart keychain with animated eyes, a bit like a tiny cyberpunk Tamagotchi that you can carry around with you. The idea is to create a little digital companion with its own personality. Its eyes could blink, look around, react to movement, show different expressions depending on what's happening, and respond to simple interactions. But I want to take it a step further: I'd also like to connect it to a custom mobile app, allowing me to control its features, customise its behaviour, and eventually add new functions without having to rebuild the hardware. Some ideas I'd love to explore: - 👀 Animated eyes and expressions that react to movement, inactivity, touch, or other events. - 🌦️ Weather updates, displaying simple animations or expressions depending on the current weather. - 🎵 Music companion mode, showing animations that react to the music I'm listening to, or displaying basic track information when possible. - 📱 Phone-controlled features, letting me change expressions, switch modes, customise settings, and trigger animations from an app. - 🔔 Smart notifications, with different expressions or animations for incoming alerts. - 💳 Payment-related features, if feasible, perhaps exploring NFC interactions or a way to trigger payment-related actions through my phone. I know not all of these features will necessarily fit into the first version, so I'd focus on getting the core device working first and expanding it from there. 2. Why I want to build it I've always liked the idea of combining software, electronics, and something creative into a physical object that you can actually carry around. As someone studying IT and interested in software development, I'd love to get more hands-on experience with microcontrollers, displays, wireless communication, and embedded programming. What makes this project interesting to me is that it sits somewhere between a tiny wearable gadget, a desk toy, and a personal digital companion.
