New Here...Need Help...

Hello all from the Great "Not White Yet" North in Calgary, Alberta, Canada!

  I just joined and this is my first post, so bear with me..

 For this last Father's day my wife and daughter built me a 24 ft 5 lane raceway. At current, I'm running 20 feet of it as I ran out of room in it's current home...I have a finish line marked at the 19 foot mark leaving a foot for run off and catch box..( I'll try to get a pic up here somehow)

 I need a finish line/gate...bad..

 I'm hoping to find an idea for a mechanical "winner indicator" of some sort. I don't have very much money right now and I'm not great when it comes to building an Ardunio unit...BUT... I'm a whiz with mechanical things and putting together odds and ends to create something.

Currently, I have a stop box built in such a way that it allows me to setup 2 cell phones to film at the finish line, then take that video, run it through a slow-mo app, and HOPEFULLY...just maybe be able to tell who won..It's a slow process and most of the time all I get a colored blurs. Most of the time I can tell who won either by eyeball or via the slow-mo replay,but.... I need a finish gate...

Can anyone help?

I know Hot Wheels made a 4 lane mechanical gate that would be absolutely perfect...well...minus one lane...but I would like to get all 5 lanes set up....

BTW...Thanks for having me here and for any help that can be offered.
