nerdish by nature

Things I make.

I’m Piet Brauer-Kallenberg, an independent developer. I write iOS apps that do one thing, ask for nothing, and send your data nowhere — and when a problem is better solved in plastic than in software, I design and print it instead.

Apps

  • AirportQuiz

    Guess the city behind the airport code. Over 3,000 codes, three modes and a Game Center leaderboard to lose sleep over.

    Coming to the App Store

  • YouUpload

    Put a video on YouTube straight from your iPhone. No laptop, no re-encoding, no account with anyone but Google.

    Coming to the App Store

  • MyRoads

    Plan a road trip stop by stop. Real driving distances between every leg, shared with whoever is coming along.

Making

Printable mounts and brackets for 12V electrical fit-outs — van conversions, mobile routers, switch panels. Free to download from MakerWorld.

  • Universal 12V USB & Power Socket Wall Mount

    An angled bracket that holds a standard round 12V or USB socket where there is no panel to cut into — van conversions, boat lockers, a workshop bench. Screws to any flat surface.

  • TP-Link M8550 5G Router Wall Mount

    A wall cradle for the TP-Link M8550 5G router, so the mobile connection lives somewhere fixed instead of sliding around a shelf.

    On MakerWorld

  • UniFi Travel Router Wall Mount

    Holds a UniFi travel router flat against the wall with the ports left clear. Corner clips let you pull it back out without tools.
