much of those ideas are wayyy too advanced for me...

perheps the carb ice one?
The PROBLEM would be, my teacher or examiner would find it hard to relate to what is happening because it can only be put use in an aeroplane.

Here is how it may work (I am not good at electronics at all) so this is just ideas (im probably not going to do this at all!):

higher humidity means greater chance of carb ice right? (provided chamber temp drops to or below 0c)

It can work via a humidity sensor (which can be placed outside the aircaft?, ive seen these humidity sensors in the catalogue) the voltage produced from the humidity sensor can be shown proportinally via a bar graph display (a series of LED's), higher the humidity, the higher the reading on the bar graph display (more LEDs come up)...

but since carb ice only forms when the ambient temp inside the chamber falls below 0celcius or below, a thermister can provide the on/off feature, the bar graph display will only work after the temperature falls below 2celsius (to give a safety buffer ), theoratically the thermister should be placed in/around the chamber (if thats at all possible), since carb ice can form in OAT of upto 30c

so in conclusion, the bargraph will display chance of carb ice forming by operating after the temperaature has fallen below 2c (and the bargraph showing level of humidity)

thereffore the greater the reading on the bar graph display, the greater the chance of carb ice forming.

Having said all that, I must say I am not good at electronics at all.
all this sounds too easy, i have no idea how i will actually build one. Even if i manage to build one, my teacher may not like it giving me a lower mark?

hmmmm....i might as well go back to the typical burglar alarm.


thanks for reading.
