What is PhDino Calc 95?

PhDino Calc 95 is a free, browser-based toolkit of structural, mechanical, electrical, and geotechnical calculators, paired with a wiki and step-by-step project guides. It's built for students and hobbyists tackling medium-complexity problems — not a replacement for professional engineering tools, but a learning-first companion for understanding *why* the numbers come out the way they do, with live diagrams alongside every calculation.
