Mastering the Flow: Practical Electronics
Like Duolingo, but for Mastering the Flow: Practical Electronics. Tomo turns the whole topic into a game you play five minutes a day, until it actually sticks.
For the part of you with thirty open tabs that never became anything.
185 levels across 8 sections, about 370 minutes end to end, roughly 74 days at five minutes a day. It moves through Building Circuits That Work, Managing Power and Energy, Storing and Timing Energy, Switching and Amplifying, Interfacing with the Real World, The Logic of Modern Electronics, Troubleshooting and Refinement, and The Physics of the Flow. It assumes you already know the basics.

Key ideas in Mastering the Flow: Practical Electronics
- Voltage acts as the initial push or pressure
- Current is the measurable movement of electricity
- Resistance is the force that opposes movement
- Higher resistance makes it harder for electricity to pass
- Increasing friction reduces the total current flow
- Distinguishing between the roles of pressure, flow, and friction in a circuit
- Predicting the effect of increasing resistance on current
- Voltage is the pressure that overcomes obstacles
- Higher pressure can force flow through high-resistance barriers
- Current is highest when pressure is high and friction is low
- High friction can choke out even a strong pressure source
- Understanding the danger of high voltage sources
- Predicting flow levels based on circuit components
- Consequences of a short circuit
- How components work together
- Current increases proportionally with voltage
You've tried the other tabs
Thirty open tabs. Four facts you actually kept.
You watched. You nodded. By Sunday it was gone.
One answer, then back to scrolling.
Eight weeks. You meant to finish. You didn't.
Tomo gives Mastering the Flow: Practical Electronics the Duolingo treatment: levels, streaks, and quick quizzes that test what you just learned. That game loop is what the tabs above never had, so it's the one you actually finish.
Here's what playing it feels like
