Second class:

water metaphor sometimes helps explain the three components of electricity

Hight of water reservoir = Potential = volts = v
Narrowness of pipe = Resistance = ohms = R
The resulting flow of water= Current = Amps = I

Fantasy Device – As a class, we’ll make a list of fantasy devices; things that don’t exist, but that we wish did. For today, we’ll ignore technical feasibility and concentrate on how you’d operate these devices if they did exist. We’ll divide into groups of 3. Pick a fantasy device from the list. Design/mockup a control interface for this device and demonstrate it in­ class. Try to think physically and avoid too much screen controls, speech and direct mind control…

It is sometimes useful to think in terms of WH questions and try to answer them in your design:

WHO? WHEN? WHERE? WHAT?

Lets take an example, A popular fantasy device in movies and books is a time machine. In movies and TV, the production has to imagine what these devices look like and how they are controlled:

“Back to the future” movie:

Time Machine control panel
Time Machine control panel
Time Machine in "Back to the future" movie
Time Machine in “Back to the future” movie

So thinking about the WH questions:

WHAT is it ? – A car.
WHO gets to go ? – anyone in the car.
WHERE does it take you ? Set in the control panel.
WHEN does it activate ? When the car reaches 80 MPS.

Stewie from “Family Guy” time machine:

Stewey's time machine control panel

Here the designers decided the machine is a cabinet, but they also added a disc that goes with Stewie and is used to get back:

WHAT? – A cabinet and a disc
WHO gets to go? Anyone in the cabinet or on the disc.
WHEN does it activate ? Not sure, but there is a big red button…
WHERE does it take you? There is a control panel, note that the control seems to be relative, so you can go forwards and backwards, not absolute like in “Back to the future”

“Spongebob Squarepants” time machine:

Here the machine is the freezer from the Crusty Crab, note that the whole freezer travels through time and it is ripped from it’s surroundings

WHAT is it ? A freezer.
WHO gets to go ? Whoever is in the freezer.
WHERE does it go? Hard to say, looks like two levers and no display.
WHEN does it activate? Hard to say, but it has some buttons.
