Cast lessons

A Cast is a lesson that runs.

A Cast combines guided narration or speech, synchronized visual focus, and an interactive simulated circuit. Available audio depends on the Cast and locale. Pause supported activities to operate controls or inspect signals before continuing. SimCast, RelayCast, and EleCast accompany published courses; AnaCast has three guided pilots, with a full Analog curriculum still unpublished.

How a Cast works

The lesson is a running simulator.

  1. 01

    The camera highlights

    The lesson pans to one component, dims the rest, and draws your eye to exactly what matters now.

  2. 02

    The narration explains

    Prepared narration with synced captions in your language. RelayCast and EleCast add hints and wait for your action before moving on.

  3. 03

    You pause and probe

    Pause anywhere, flip switches, inspect signals, and keep experimenting with the live circuit. Then let the Cast continue.

A recurring learning cycle
  1. 01 · BuildPlace a battery, a switch, a relay, a lamp.
  2. 02 · MeasureRead the meter: 6.0 V across the coil.
  3. 03 · PredictWhat happens to the lamp when the contact flips?
  4. 04 · VerifyFlip the switch. The circuit answers for itself.
Three published Cast experiences

Guided learning on each released course.

Each Cast uses its lab’s simulation model. SimCast, RelayCast, and EleCast accompany published courses. AnaCast has three guided pilots within the eight Analog starters; a full Analog curriculum is not published.
