Debugger

The Debugger in orange, white and blue, seen from the front right
CGI render of the current prototype

A hand-pumped insect remover for the fly that always gets away.

Pump it once, aim, and squeeze. A puff of air carries a pinch of kitchen semolina and knocks the fly off the window. No spray, no swatter.

Engineered in Germany. Built by hand by the person who designed it.

The concept film shows the two problems the Debugger was built for, how it works, and what happens next.

CGI concept film of the current design. Real footage follows once the final version is built.

How it works

Three moves. No batteries, no chemicals.

  1. The orange hopper lid slid open while semolina falls into the hopper

    Fill

    Slide the orange lid aside and pour in semolina straight from the kitchen cupboard.

  2. X-ray view: the slide pulled back and the two latex bands stretched

    Pump

    Pull the blue slide back and push it home. Two latex bands store the energy, and a small drum measures out one pinch.

  3. A small cloud of semolina grains leaving the nozzle

    Release

    Aim and squeeze. A piston drives a short puff of air through the nozzle and carries the pinch with it.

Designed down to the last screw

This is the current prototype, revision 7.2, drawn to scale. Its assembly manual runs to 40 pages.

Made by hand in Germany

I’m Christian, an engineer in Germany and the one-person workshop behind Swatsmith. I designed the Debugger myself, from the first sketch to the last screw, and reworked it through seven revisions.

It isn’t mass-produced. Every Debugger will be printed, assembled and tested by hand, by me, in small numbered batches. That’s slower than a factory, and it means each one is checked by the person who designed it.

Questions

Can I buy one now?
No. The Debugger is in development and not on sale yet. Joining the waitlist is free.
When will it be available?
If enough people sign up, the first batch is planned for spring 2027, in time for fly season. Waitlist members hear first.
What will it cost?
The price isn’t set yet. Tell us in the form which version you’d want. It helps decide.
Why semolina and not salt?
Salt draws moisture from the air and can clump inside the mechanism. Semolina stays loose, costs little and is already in most kitchens.
Is it safe?
It isn’t a toy and is meant for adults. Wear eye protection, and never aim it at people or animals.
Can I use it on wasps or bees?
Please don’t. Leave wasps, bees and hornets alone. Hornets and wild bees are protected in Germany.
Are the pictures real?
The images and the film are CGI renders of the current design. Real photos and footage follow once the final version is built.
Where is Swatsmith based?
In Germany. The Debugger is designed, printed and assembled here.
