Small tools, made carefully.
Lumi is a two-person design and prototyping studio in Tallinn. We build interfaces, small hardware and the quiet software that connects them.
Selected work
Harbour schedule display
E-ink timetable screens for a ferry terminal. Readable in direct sun, updated twice a minute, runs for months on one battery.
Greenhouse sensor kit
Soil and air sensors for a family farm near Tartu. Simple dashboard, alerts by SMS, no subscription.
Booking page for a ceramics studio
A calm, fast booking flow for weekend classes. Replaced three spreadsheets and a phone line.
Wayfinding study, Old Town
Field notes and prototypes for clearer street signs aimed at visitors walking without a phone.
Notes

Designing for long winters
What changes when most people use your screen in the dark from October to March.

E-ink refresh, without the flicker
Partial updates, ghosting and the trade-offs we settled on for the harbour project.

One battery, one season
Notes on power budgets for outdoor sensors that nobody wants to visit twice.

Why we still sketch on paper
A short case for slow first drafts.
About
We started Lumi in 2022 after years of working inside larger agencies. We take on a handful of projects a year and stay with them from first sketch to the version people actually use.
Currently booking projects for spring 2027.
