Built a modular graphene-compatible smartwatch from scratch. No lab, no VC — just one man, one mission.

I’m a USMC scout sniper veteran turned independent inventor. I’ve been building a tactical smartwatch platform, not as a consumer gadget, but as a modular, rugged, low-power system that integrates solar, piezo, and (eventually) graphene-based battery tech. The watch is built around an ESP32-S3 with a Waveshare 1.85” capacitive touch display. It uses a snap-fit rugged housing I 3d printed myself, plus a hybrid power path that prioritizes solar and motion harvesting over battery whenever possible. No corporate funding. No academic lab. Just a 3D printer, a bench full of parts, and a stubborn desire to see what’s possible when you build for real-world resilience, not market trends. Current stack includes: BQ24074 charger + TPS22917 switch + MCP1640T booster Custom PCB in development Monolithic perovskite solar test panel Modular ports for future haptics, RF comms (LoRa), and graphene-battery integration I call it Ghostwatch. It’s still in development, but already pushing limits in power autonomy, form factor, and purpose-driven design. Feedback, questions, or collab interest welcome. And yeah, if you like it, upvote so I can finally post in the cool subs without looking like a ghost myself.
