Hang in There, Kogasa-san 3309
Of course you know I was looking forward to the Kyoto con too, right? :-)
This altimeter measures altitude starting from a point of reference (home), and I've made it so even if its power gets cut, that altitude will not disappear but will be retained in its nonvolatile memory.
Since it measures based on stuff like air pressure and temperature, the numerical values change even when it's at rest, so I made it so it obtains the car's speed pulse and doesn't update the values when at rest.
Thus, it weakens the motion sensor's sensitivity, rendering it almost ineffective. I remembered the speed pulse comes out of the car after I attached the motion sensor, so this is how it went. (^^;)
