Learn to Sketch: Shading and Shadowing Cylinders

Until recently, how to shade and shadow cylindrical objects has been a mystery to me. I had known there should be areas on the surface shaded lighter and others darker, but I didn’t quite know where those should be. Understanding the physics and practicing the sketches in a detailed way (a few times) helped me lock in the core concepts. Now I can sketch them quickly without trouble. This article shares the physics and provides a step-by-step process for skill building.

Inspiration from History: Design in the Wilderness

I am often inspired by design triumphs in history, but there is one design that has particularly influenced me. It is a humble design: an odometer made from wood for covered wagons that was never put into mass production. Part of what makes it interesting is that it was done under harsh conditions with the goal to help other people and it would become a legendary part of an epic exodus and the settlement of the Western United States.
