AstroNav
My ongoing model-rocket project: a custom flight controller, wireless telemetry, a handheld base station and a lot of lessons from real launches.
RP2040 Custom PCB Sensors
Welcome to Youp's space
I build rockets, electronics and whatever seems fun.
I'm Youp, a maker from the Netherlands. This is where I document ambitious projects, failed tests and everything I learn while turning unusual ideas into real hardware.
CURRENTLY BUILDING / testing the next AstroNav ideas one revision at a time.

Active project
Main project · AstroNav
Learning what happens inside a rocket during flight.
AstroNav grew from a simple question into a custom flight computer, sensors, data logging, wireless telemetry, a handheld base station and a series of launches that never go exactly as planned.

Best Maker 2025
I showed AstroNav at Maker Days Eindhoven in September 2025. The project was nominated, and I received the title Best Maker 2025. The jury also valued the story behind all the building and learning.

Sharing the useful
bits
I share my projects to show that anyone can start building something cool.
Not everything works the first time—plenty of my ideas don't. But every broken part, bad assumption and new revision teaches me something worth sharing.
