James,

The bottom 2 pictures show the start mechanism. Basically it is a T shaped piece of ply in a 1/4 inch groove held up by rubber bands. There is a dowel glued to strike the right key on a wired USB keyboard when the back wheel travels over it. This starts the stopwatch. At the bottom end, the hinged box holds a wireless keyboard. The cord on the keyboard receiver barely stretches far enough for good signal once the keyboard is in the box. There is a dowel set to press the stop key when the cart bumps it.

It was actually an elegant solution to what could have been a complicated and expensive timer build, and much more accurate than hand timing. Fortunately "Goodwill" has cheap keyboards, because I wasn't afraid of damaging my nice ones!

Sure looks like she got your engineering mind. Great post , thanks for sharing your family time together. A lot of work involved, she must be determined most kids would have bailed out in the beginning.

Update:

Well, Yesterday was the Piedmont Region science fair at the John Paul Jones arena at UVA, where the winners from 40 middle schools from Central Virginia competed for a chance to go to the State final. She was honored just to be sent there, but ultimately only received honorable mention in her category. (of course that is as good as first place to me!)

She still tells me she doesn't want to be an engineer when she grows up, but that it is fun doing these projects. There are worse hobbies I guess! We are working on the 'real' go cart using some of the results from this experiment, hopefully it will be ready when the weather gets better.

This is my first time attending a Regional Science Fair. As a spectator, there were some amazing projects on display. Some of the work was definitely well above what I would expect of their ages, and kind very impressive.

For the high schoolers, there was some significant money available in awards. One team picked up about 5 awards, totalling around $800. Unfortunately, my oldest's high school does not have a science fair, she may have to see if she can enter one of the other schools nearby.

That was very exciting Doug. It was nice to see you feeding her curiosity. Thanks for sharing.
