Afterthoughts on sketch 2

So a lot of successes occured during sketch 2 as well as a few disappointments.

To recape the idea, the entire premise was that you could have a self popping collar depending on the wind conditions. This would in turn allow you to be protected from the elements without having to manually lift your collar.

The idea was to create my own sensor to detect the wind, by combing essentially, 2 different levels of tinfoil to complete the circuit and give a HIGH on a digital pin.

When the circuit completed, the sensor would activate the servo motors.

In the end my shirt worked well, however there was two main problems that occured which was the thread not carrying enough current, and the sensor being too twitchy.

The snsor was too twitchy simply due to the inertia it had affecting it when I was walking. I thought that i coule fix this problem by making the ball ont he end smaller, and taking off weight, but in the end it still ended up too twitchy.

The thread simply did not have enough capacity to carryt he current requires for the servo motors to function. I attempted to weave the thread and to make it thicker as to increase it's potential for current flow, but nothing worked so in the end I had to resort to just thin wires with a gauge capable of the current flow required.
