I've spent 25+ years in IT, and these days most of my spare time goes into building with AI. This is where I put the tools, projects, and experiments that come out of it, and where you can find me if you want help making technology work for you.
Most of these started as "I wonder if I could…" and turned into something useful. They're free to use. Poke around.

From Turing to today in one scroll. The whole page changes its look as you move through each decade. Nerdy, fun, and a good reminder of how fast we got here.
A living 3D map of the county I grew up in and still call home. Spin it, zoom in, and explore the towns from above.
Eight guided builds that turn an Elegoo Mega 2560 starter kit into experiments in flight, structures, machines, and intelligent systems.
New tools and guides land here as I finish them. If there's something you'd like to see built or explained, tell me.
A hands-on lesson in building AI agent systems that don't burn through tokens. Pick an architecture, run the pipeline, and watch the cost estimate move.
Open the simulatorA 3D look at how Earth's orbit and tilt drive ice ages. Adjust the orbital cycles and see the 65°N sunlight respond.
Open the labA look at the Motorsports Engineering program at Purdue in Indianapolis: what it is, how it's built, and where it can take a future race engineer.
Read the guideA decision brief on Purdue Indianapolis's B.S. in Artificial Intelligence: the curriculum, application timeline, campus comparison, and questions to ask.
Read the briefA day-of plan for a campus visit: parking, check-in, campus maps, and the schedule from arrival to the Informatics session, all in one place.
Open the itineraryA field guide for high schoolers — and their parents — on the AI-shaped job market: what employers actually want now, and why “trust but verify” was always the real skill.
Read the guideA tutor for every kid, a reality check for every claim: the evidence that school isn’t preparing students for work, and what parents can demand instead.
Read the briefAn animated lesson for curious kids: follow one photon from the Sun’s core to Saturn to your eye through a 10-inch Dobsonian — then ride starlight across millions of years.
Start the lessonFive societies where staying safe meant saying what you didn't believe, and what that habit costs a community, from Havel's greengrocer to today.
Read the essayAn open-source synthesis of the UAP disclosure record: official reports, congressional action, and the case for non-human intelligence, laid out as a case file.
Open the fileWhat GLP-1s change before insurance can price it: rumor vs. truth on autonomous vehicles, data centers in catastrophe zones, and where risk goes when it leaves. Evidence graded, open questions marked.
Read the briefA seven-part study on lament, frailty, and the God who stays, written for anyone walking through a hard season.
Read the studyA weekly family and marriage Bible study built around Bible Project videos. Same video, two tracks of discussion questions: one for the whole family, one for husband and wife.
Open the studyAI is the thing I'm most excited about right now, but it's only one part of the picture.
If you want to get more out of the tech you already have, at home or at work, I'm happy to help you sort out what's worth your time and what's just noise. Plain language, no sales pitch.
For you and your family
For your job or small business
For the tinkerers
Send a question, even a vague one. "Where do I even start?" counts.
We work through it hands-on, with the tools you already have where possible.
You leave knowing how it works, not just that it works.
About a project on here, a piece of tech that's giving you trouble, or something you'd like to learn. I read everything.
