First signs of weathering.

By Dermot Tynan, about 8 years ago.

In order to test the spiffy, new Wind Direction Indicator mentioned in The Marvel of 3D Printing..., I assembled the mechanical components (without the potentiometers) and mounted it outside. As we live in a wind-swept area, with a high concentration of sea salt in the air, it was a useful test of how the system would perform. What I couldn't test was the effect of high temperature/humidity in a salt-water environment. To do that, I'd have to move to the Caribbean (which seems like a good idea, given the Irish summer we've had so far!).
