Welcome to n390

This is where I document the projects, experiments, and rabbit holes that capture my curiosity. Some become educational programs. Others turn into software, research, electronics, model rockets, or simply an excuse to learn something new.

You’ll find technical articles, open-source software, STEM resources, engineering projects, and whatever else seems worth building or understanding. The topics may change, but the approach stays the same: ask questions, experiment, and share what is learned along the way.

Choosing a Rocket Parachute: Why Descent Speed Matters

How big should a rocket’s parachute be? Most online calculators make this straightforward: enter the rocket’s recovery mass, choose a descent speed, and calculate a parachute diameter. That is a useful starting point. If you accept 6 m/s—about 20 ft/s—as a suitable landing speed, the familiar mass-based calculation gives you a parachute size under its assumed … Continue reading Choosing a Rocket Parachute: Why Descent Speed Matters

Astronomy Enrichment Program

Mosaic of astronomy images collected by me

Control real telescopes. Capture real images. Explore the Cosmos. What happens when a student points a professional telescope perched on a mountaintop thousands of miles away at a galaxy, and watches the image build on their own screen in real time? Students don’t just learn about the night sky, they capture it. Using Slooh’s network … Continue reading Astronomy Enrichment Program
