Building an Overengineerd Doorbell With Simone Giertz

Laura Kampf and Simone Giertz spent a whirlwind day at a junkyard hunting for parts, then turned their finds into a hilariously over-the-top doorbell. Expect wild contraptions, creative problem-solving, and plenty of unexpected moments as they cobble together pneumatic tubes, sensors, and whatever else they can scavenge.

Along the way, they lean on sponsor tools like Festool and share links to Laura’s shop, Patreon, and social channels—so you can build along or just enjoy the madness. It’s a one-day build that proves you can never have too many features on a simple doorbell.
