Planning
Ergo Glass
A detachable module for ordinary glasses: local lifelogging with clear opt-in controls and a physical kill switch.
Quick overview In plain language
What it does
A concept for a small camera and sensor attachment for ordinary glasses, with local recording and a physical way to stop sensing.
My contribution
I’m planning the electronics and how the attachment would fit and work on a pair of glasses.
Where it stands
This is in planning. The features described are design goals, rather than a finished device.
Concept
Instead of a dedicated smart-glasses frame, this is a module you can move between glasses you already own. With approval, it can capture useful context, keep as much processing local as possible, and always give you a physical way to stop sensing.
Hardware stack
ESP32-S3, ESP-IDF, aggressive idle and frequency scaling.
OV5640 with hardware standby; motion before heavier processing.
BQ24040 charging, TPS62840 regulation, switched camera rails.
microSD and MEMS mic for ambient capture.
BLE for control; larger transfers on demand.
