EASILY DETERMINE WHO THE WINNER IS IN YOUR PINEWOOD DERBY RACE 

Do you often guess or argue about who the winner is in your PWD race?  The winning cub scout  shouldn't be the one whose father has the loudest voice.  

This circuit device is not a timer but rather a circuit that will tell you who was the first to cross the finish line in your Pinewood Derby race.  It will also tell you who was second, third and fourth.  The device can handle up to four lanes.

IF YOU HATE COMPUTERS YOU WILL LOVE THIS SIMPLE DEVICE.

To use this device, start your race as usual and as the cars cross the finish line the first to cross will cause his indicator led to go on.  This car is the winner.  The second car to cross the finish line will have his indicator led start blinking.  This car is the second place winner.  The third car to cross will have his indicator led blinking about half as fast.  This car is the third place winner. The last car to cross the finish line will have his indicator led off.  

 

That is all there is to it!  What could be easier!

 

Here is a block diagram of the system:

To reset the device just turn the unit off and on, and you're ready for your next race.

The device operates on a 9-volt battery.  This device will work on tracks with 2 lanes, 3 lanes or 4 lanes max.  

This package includes the main unit box, 4 sensors with mounting hardware and pre-printed sample race sheets with a link to where you can get more free (pdf file downloads).

Pictured to the left is a sample score sheet.  It is for a 4-lane track.  There are 4 heats.  This means that each cub will get to race his car in every lane. The four cubs in the first race are: Bob, Wade, Dave and Jeff. 

 

After Heat 1, you need to enter the order of the winners.  Bob finished first, Wade finished third, etc.  After the four heats are done just add the numbers in each row. 

 

For Bob the four numbers are: 1 + 1 + 2 + 2 = 6.  The lowest Total number is the winner in this race Bob.  Wade is the second place winner. 

 

You start with a blank score sheet and will have to enter the cub names.

 

 

The sample race sheets are for two, three and four lane tracks.

You use the race sheets to keep score which means you are keeping track of who was first, second, etc., in each race.  The ultimate winner depends on how you decide to use the information that you collected on your race sheets.  You might want to do a double elimination race.  The instruction manual describes how to use the sample race sheets.  There are some interesting variations that you can try.  

The four included sensors work with room light.

The installation involves drilling a hole in the center of each lane at your finish line and attaching a sensor underneath.  Screws are provided.   The sensors get plugged into the main control box.

If you are racing 4 cars and one or more do not cross the finish line then what?  A built-in circuit timer will end the race after 6 seconds and any car that didn't finish will be placed in last place with his led off.  A typical PWD race lasts about 3 seconds at most. 

The circuit is mounted in a plastic box with measurements 5 inches by 2.5 inches.  The four sensors plug into this box. Each sensor cable is 3-feet in length.  A sensor is shown in the picture.  Each sensor is 2 inches long and mounts with 2 screws.  

This whole package costs $79 and the shipping is free.

Please allow ten days for shipping. 

This product will also work with the Space Derby (using different sensors).  If interested please tell us.  It is the same price.

 

Please ask questions.  Thanks.
