EASILY DETERMINE WHO THE WINNER IS IN YOUR PINEWOOD DERBY RACE
IF YOU HATE COMPUTERS YOU WILL LOVE THIS SIMPLE DEVICE.
NEW FOR 2018 - A 4-DIGIT DISPLAY
If you are wondering what the 4-digit display is, we'll tell you. Rather than blinking leds to show the winner, we now have a four digit display to show who the winner is. The four digits represent the four lanes (or 3 lanes or 2 lanes?). The leftmost digit is for lane 1. Th rightmost digit is for lane 4. Initially the four digits show 0000. After each race the display is updated to show who won the race. For instance, if the display shows 2143, it means that the car in lane 2 won the race. Lane 1 is next, and so on.
But wait, there's more. A SELECT push button has also been added to allow you to see the times. Above each digit is an led. Pressing the SELECT push button will light the led above digit 1 and show the time for lane 1. The time is shown in milliseconds. 1000 milliseconds equals 1 second. Pressing the SELECT push button again will light the led above digit 2 and show the time for lane 2. This is great because sometimes a cub will want to know his time. You don't need to use the SELECT button if you are not interested in seeing the actual time measurements.
Pressing the RESET button will clear everything, reset the display to 0000 and ready the WINNER circuit for the next race.
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 $149 and the shipping is $12.
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.
