About me

Hi, I'm Jacob.

I study at Aarhus University, build apps, and every now and then wire a sensor to something.

This island is where I keep the things I've made. Walk around up there, or scroll on for the list of projects.

Pin board

Places I've been

Every pin is a place I've travelled to, and the countries I've been to are painted gold. Drag to spin the globe, and scroll, pinch or use the buttons to zoom in.

Projects

Lighthouse

Vokly

An iOS app that shows you a new Danish word every day.

A widget puts the day's word on your home screen, and a daily letter game keeps you coming back with streaks, hints and a timer.

Windmill

EduRoom

Room booking for universities.

Students and teachers book lecture halls, meeting rooms and study spaces, and conflicting bookings are caught automatically. Built with my team as a semester project, with separate roles for students, teachers and administrators.

Market stall

ElCoS app

The app for ElCoS, the tutor association at Aarhus University.

Tutors photograph a receipt right after buying something and submit it. The treasurer approves it, books it and exports everything to a spreadsheet. There's also a feedback inbox, push notifications and login with a code sent by email. Out now on the App Store.

Telescope

This website

A Raspberry Pi next to my coleus plant that measures the room and serves this site.

Sensors for temperature, humidity, air pressure, air quality, CO₂ and soil moisture feed a small database. A C program runs Bosch's air-quality library, a Python server builds the pages, and a Cloudflare Tunnel brings them to the internet.
