Personal projects: satellite pictures, ATAK tools, and field software that runs on your own machine. Most of them you can try in the browser.
The Satellite Pass Directly Overhead Is the One You Cannot Use
Predicts when a radar satellite can actually image a spot, which is not the same as when one flies over it. About a quarter of passes are usable, and the best-looking ones are the worst.

A Camera That Needs a Password Can Never Be Handed to ATAK Directly
Maps 35,944 public cameras and re-publishes any of them as a stream ATAK, VLC or a recorder can open. The format ATAK uses for video has nowhere to put a username, which decides almost everything else about how it works.

Winds Aloft to 103,800 Feet, Anywhere on Earth
Wind from the ground to 103,800 feet, anywhere. The holes in the ladder are interpolated and marked, then handed to ATAK, Google Earth, or anything that opens KML.

Live Bathymetry for Google Earth, ATAK, and a Chartplotter
Live water depth for any area you pick, exported for Google Earth, ATAK, QGIS or a chartplotter.

The Landing Pin Is an Estimate
Predicts where a high-altitude balloon flies and where it comes down, then hands you the track for ATAK. Estimates only.

A Tone You Cannot Hear, Keyed Slowly Enough for a Camera
Morse over sound, light or vibration, including carriers above adult hearing. One pulse train feeds every channel, and most of the work was finding out which of them a phone actually carries.

Nobody Could Land It, and the Difficulty Was Never the Problem
A browser game where a Starship-shaped vehicle falls belly-first at terminal velocity, flips, and lands on a ring or on a droneship deck heaving in a swell. It was unlandable for weeks, and never because it was hard.

I like making tools that help you see the world a little more clearly — whether that is a satellite pass overhead, the wind at 80,000 feet, a ship on the water, or the bottom under it. Space, air, sea, subsea: same itch. What is actually there, and can I hold the answer in my hand.
