Key information: Terrain section states that steepness below 25˚ or above 60˚
presents low risk and that peak risk is in the 35 to 45˚ slopes.
The hardware could involve an accelerometer, LCD, pushbuttons to select mode,
and a piezospeaker for alarm. The key to the prototype would be to demonstrate
that the device can detect certain levels of risk from, say, the base of the slope.
Features can be added assuming the prototype is approved.
Note: Ski resorts regularly maintain their slopes by taking these measurements
and then launching explosive charges into the hill to create small avalanches,
thereby preventing a larger avalanche later. So even though it might seem risky
to measure from the bottom of the slope, we are talking about a slope that is
regularly maintained to prevent avalanches.
The prototype involves using your board to sight the top of the slope from the
base, which turns out to be a simple modification of the application discussed in
this Chapter’s Activity #1. A
modified version of VertWheelRotation.bs2 that displays different messages on
the LCD based on the measured angle. The
like this when you’re done:
READ counter, dataItem
DEBUG dataItem ' Format wasn't specified, so nothing like DEC was
FOR char = 4 TO 0
NEXT
DEBUG CLS, "Datalogging starts", CR,
FREQOUT 4, 50, 3750
PAUSE 950
"in ", DEC2 char, " seconds",
CR, CR,
"Press/release Reset", CR,
"for menu..."
' used. If DEC dataItem was used, it would still be
' right because that's what the text examples used.
