The Story

It started with a simple observation: wether at school, or in the office, we usually carry a ruler with us. So why not make that everyday tool more personal and fun?

After buying a basic electronic PCB ruler online, I realized I could build something much more personnal. That's how the Retro-Ruler concept was born.

Version 1 proved the concept worked, despite 3D printing limitations. The Kickstarter sold out in 48 hours - all 50 units gone!

Hand-assembling 40 components per unit was challenging, but it taught me what needed improvement. Version 2 added sound, better ergonomics, and required two complete PCB redesigns.

Built with passion in France, every component carefully chosen for the perfect balance of function and fun.
