Research
What science already knows, what equipment exists, and where the open questions are. Written so you can check every claim.
Background research behind OpenLucid’s choices. Every page lists its sources; prices and specs are dated, because they change.
| Page | What it covers |
|---|---|
| EEG and eye-movement options | The sleep-lab standard (polysomnography, EOG beside the eyes), how lucid-dream research verifies the left-right eye signal, every realistic device with its price and data access, validation studies, and a budget for home, validation and lab setups |
| Build your own eye-movement sensor (EOG) with an ESP32 | Why eye signals are easy to measure, which cheap boards work, safety rules, a first build for about €50 (BioAmp EXG Pill + XIAO ESP32-C3), firmware outline, and how to validate it |
| EOG build: where to find the parts | Every part with shops in the Netherlands, the EU and worldwide, prices and stock as checked on 1 November 2026, and what could not be found |
Build your own eye-movement sensor (EOG) with an ESP32
Why eye signals are easy to measure, which cheap boards work, what it costs, how to stay safe, and how it plugs into OpenLucid.
