01 / DC FUNDAMENTALS
The voltage divider
Two resistors. One useful lesson in voltage, current and loading.
10 V in → 5 V out Build video · 0:31Circuit simulation examples: One question. A few components.
Predict a result. Run the circuit. Change one thing. These examples connect a useful equation to a result you can see.
02 / FILTERS & FREQUENCY
A signal, smoothed out
Watch an RC filter reduce a signal, then find its corner frequency.
500 Hz in → 0.303 V peak Build video · 0:33
03 / DIODES & WAVEFORMS
One direction changes everything
See a diode pass the positive half of an AC waveform.
AC input → half-wave output Build video · 0:34
04 / POWER CONVERSION
Twice the voltage, no inductor
Four switches and a flying capacitor stack a 5 V supply on itself.
5 V in → 9.90 V out Build video · 1:32Images and measurements come from the real desktop development build. The named projects are bundled examples; they are not an in-browser simulator.
