Three devices from my home lab. Designed, PCB'd, printed, and shipped by one person. Hover the classified bits to declassify.
Egg
VOICE-CLONED TTS COMPANION · FOR MOM
FIG.1 — PRODUCT · 3D-PRINTED ENCLOSURE
FIG.2 — MAINBOARD EGG-01 REV.B · DESIGNED FROM SCRATCH
The field unit speaks with my own cloned voice — the browser demo falls back to your system's Korean TTS. The board viewer walks through the actual PCB stackup I designed: copper, silkscreen, and drill.
- Mission
- Daily check-ins, medication reminders, and greetings for one very important person
- Voice
- TTS model fine-tuned on recordings of my own voice, fully offline
- Mainboard
- Custom PCB — audio amp, battery charging, touch sensing
- Enclosure
- 3D-printed egg shell, weighted to sit in one hand
- Compute
- Embedded Linux board
- Connectivity
- Local network only — no cloud, ever
- Battery
- Li-Po with charging base dock
- Status
- Deployed & loved ♥
Mini AI
SELF-HOSTED PERSONAL ASSISTANT · 24/7
FIG.1 — LIVE RECREATION · LOCAL LLM INFERENCE
- Mission
- Household intelligence — answers, memory, voice — with zero packets leaving the house
- Model
- Quantized local LLMs, tuned to fit small silicon
- Privacy
- Air-gapped inference · no API keys · cloud calls: 0
- Network
- Serves the household — including EGG-01 — over LAN
Clearsight
AR SPY GLASSES · THROUGH-WALL HOLOGRAM · REMOTE · CONCEPT
The goal: look at a wall through the glasses and see a holographic reconstruction of the person on the other side. Sensing is split by distance — mmWave radar (near), WiFi CSI (far), RF scan (ambient) — fused into a body pose that's drawn as a hologram on the lens. A handheld remote switches the view between full hologram, skeleton, and an x-ray build-up scan.
FIG.1 — WHAT YOU SEE THROUGH THE GLASSES · A HOLOGRAPHIC PERSON BEHIND THE WALL, SWITCHED BY THE ON-SCREEN REMOTE
- L1 · Near
- mmWave radar (ESP32-fed) — presence & micro-motion within a few meters
- L2 · Far
- WiFi CSI sensing — coarse through-wall silhouettes at longer range
- L3 · Ambient
- SDR RF scan — nearby devices, BLE beacons, 2.4 GHz activity
- Fusion
- Phone / PC merges layers into a body pose & distance estimate
- Hologram
- Pose rendered as a translucent through-wall figure on the lens
- Remote
- Handheld BLE remote cycles HOLO / SKELETON / X-RAY scan
- Display
- Brilliant Labs Frame / Halo — open SDK, HUD drawn directly
- Status
- Concept & feasibility — sensors, fusion logic, long parts wishlist
