Pinewood Derby Electronic Finish Line

2 questions regarding this circuit.

1) Can you simply replace the push button switches with Tilt switches as the activation device?
2) Also I see a master reset switch being used. I need for it to automatically reset each time without some switch having to be pressed.

For example the car hits the tab with the attached Tilt switch which causes the light to flash.
The tilt switch on the tab will rock back to it's original position automatically once the car passes through it. Based on this circuit would that action alone make it ready for the next race or would you need to modify it further?

Come on guys, chriscc17 has tested his tilt switches and they work to his satisfaction. He came for a circuit that would work with them.

I don't see why it's so important that he try different sensors.

A kludge (or kluge) is a workaround, a **broken link removed** solution, a clumsy or inelegant, yet effective, solution to a problem, typically using parts that are cobbled together. This term is diversely used in fields such as computer science, aerospace engineering, Internet slang, and evolutionary neuroscience.
