Switching power supplies are usually taught as equations, yet most of what they do comes from one fact: a coil resists any change in its current. This app builds on that, lesson by lesson, from a single coil to designing a 20 V to 5 V USB-C supply.

Built with Opus 5.5. All ten lessons ↓

The ocean is made of code, the light is computed and every move the boat makes is physics. All of it fits in under 8 MB.
