Transistors: The Switches That Think
Like Duolingo, but for Transistors: The Switches That Think. 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.
A short one: 8 levels across 2 sections, about 16 minutes end to end, roughly 3 days at five minutes a day. It moves through The Digital Switch and From Gates to Computers. It starts from scratch.

Key ideas in Transistors: The Switches That Think
- Transistors act as switches for electrical current
- Transistors are solid-state devices with no moving parts
- A small electrical signal triggers the transistor instead of a physical push
- Mechanical switches fail due to physical friction and wear
- The control signal and the main flow are both electrical
- The 'switching' happens through the movement of electrons, not physical metal arms
- The durability advantage of solid-state components over mechanical ones
- The Base pin is the control input
- Binary code is built from two distinct states
- The fundamental function of a transistor as an electrically-controlled switch
- Current flows between the other two pins only when the Base is activated
- The 'Off' state of a transistor corresponds to the digit 0
- A small amount of energy at the Base controls a larger flow elsewhere
- Transistors operate at speeds far beyond human perception
- The function of the three pins using the faucet analogy
- Switching speeds are measured in millions or billions of cycles per second
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 Transistors: The Switches That Think 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
