GREETINGS! and welcome to Let's Derby, a custom designed Pinewood Derby
track system that takes all of the guess work out of races. No more close calls, near misses or bad judges.
All of the electronic components were designed by myself. As you look through the different sections of this
site, I hope you will see the detail put into the system.
The starting gate is a fully automatic design. A motor is used to, smoothly, control the gate to lower and
raise it into place. A digital finish line utilizes infrared sensors to detect the cars as they cross the line.
Large 3" numbers display 1st, 2nd & 3rd place. Smaller .4" numbers display the race time of each car underneath
it's place indicator so each car owner can see how their time compares with the leaders.
Three large LED signs display 1st - 6th place. A
wireless module is used for the data transmission so the signs
can be placed anywhere in the room for best visibility. At the end of the race, the signs can scroll through
the entire standings so every Cub can see where they placed.
When the Cub's car is weighed and checked in, their name is entered into the system so the LED signs can display
their name along with the time of their car. Nothing excites the Cub more than seeing their name up on a Leader Board.
People have told me this is the best track they have ever seen and is very professionally done. Just give me a call or
send an email to schedule your next pinewood derby race.
The Finish Line has a resolution of .0001 seconds. There have been cars .0001 seconds apart. Let's see you 'eye-ball' those...
Audiences have said this is the best setup they have ever seen, "Very Professional"
Large LED Signs show the top six cars through the entire race. We average all lane times so we get an average performance for each car.
Once Pack Meeting is over, Cubs and siblings can race for fun as long as they want... Well, as long as Mom & Dad will let them.
I have everything needed for the race (except awards):
These rules are just a suggestion. I gave each boy a copy when I was a Cubmaster.
