pinewood derby car with headlights using chibitronics

by:Lanson     2020-03-19
The Pinewood Derby cars are fantastic and the kids love to make them and they learn a lot about carpentry, painting, aerodynamics and weight distribution.
Enhance the experience (
Make your car cooler)
Add LED headlights or taillights.
For this year\'s cars, it\'s easier for us to use Chibitronics to increase these effects.
The following Instructure will take you through the whole process of adding LED headlights or taillights to the Pinewood Derby racing car.
To complete this instruction, you will need the following: Chibitronics LED Starter KitPinewood Derby car kit pencil tweezers 1/4 wood screw small Binder (
Of course, you need all the tools to make a pinewood derby car)
It would be helpful if you planned your car from the start, including Chibitronics.
Before starting any cutting on the car, make sure where you want to put the LED and battery.
It would be helpful if you first draw your design on paper and then transfer it to the actual car.
Keep in mind that once your car design is cut off, some (if not all) Chibitronics locations will be removed and may need to be re-created
Stop in your car.
In the design, be sure to leave at least 1/2 flat for your LED sticker and at least 1 square inch flat for your battery.
You also need to consider how the copper tape will affect the look of your car.
We used two cars to demonstrate the difference between adding lights before and after painting.
Once you have decided on your car design, start by drawing a sketch gently on the surface of the car.
Mark the location of Chibitronics and batteries on the car.
Complete all the steps required to prepare and complete the car.
The last step should be to add the Chibitronics circuit.
It is best to add Chibitronics stickers after you paint your car, because stickers tend to stick better to painted surfaces than raw wood or primer.
However, for your design, you can decide to put a sticker before drawing.
The photos here show the difference between the two options.
On the black car, we applied the primer to the car and then added the copper tape and LED sticker before applying the last layer of paint (
We covered the LED sticker with small tape from the blue painter).
On the red striped car, we added copper bands and LED stickers after applying the last layer of paint.

A battery that is permanently connected to make disassembly simple.
While there are more complex methods, the easiest way is to use 1/4 wood screws to connect one side of the small binder to the car, as shown in the figure.
Please note that plastic or other non-
Conductive materials are recommended;
If a metal clip is used (
Like we did on red and black cars)
You need to add some kind of insulation to prevent the battery from being short-circuited.
The next step is to plan the Chibitronics circuit.
If you\'re not sure how the Chibitronics circuit works, start by looking at some videos on their website.
First mark the position of the lamp (in our cars.
Headlights or race stripes)
And copper tape.
Draw the circuit wiring on the body using a ruler or a straight edge.
Next, determine where the battery is placed.
It is best to put the battery on a flat surface to ensure a good connection with the copper tape.
Once you consider the location of the battery, track it around the battery so you know where to terminate the circuit.
Be sure to mark the polarity of the battery.
If you are using the effect tag, please create a location for If first as it may affect the design of the circuit.
It is recommended to close the effect sticker to the battery.
Make sure to mark each corner of the effect label correctly as this makes it more challenging to draw the remaining circuits.
Once you have the battery and LED (
And effect labels (if applicable)
You can design the rest of the circuit.
Keep in mind that the Chibitronics conductive tape is about inches (3mm)
Thick, you will want to leave inches (3mm)
Between the positive and negative parts of your circuit.
Start at the circuit side closest to the battery.
Starting with the battery holder, apply the conductive tape carrying power to the LED sticker (
And effect labels (if applicable).
Keep in mind that the front and neutral sides of the circuit should not be in contact.
Leave plenty of extra copper tape so you can reach your battery case.
Remember, you can always cut later and you can\'t wear more clothes without re-cutting
Wiring your entire circuit.
Please pay attention to the polarity of the battery when creating the circuit.
When applying an LED sticker in a later step, you need to know which side of the circuit is negative and positive.
It is also worth noting that you should not try to repair or attach conductive tape.
If your tape is broken, remove it and start over.
Attempting to add a tape can result in unreliable conductivity, which may mean circuits that cannot be operated.
Connect each LED sticker to a conductive adhesive strip using tweezers.
Press the sticker firmly on the surface of the car to ensure good contact between the conductive tape and the copper conductor on the LED sticker.
If you are going to use the effect tag, put it on now, otherwise skip to the next test circuit.
Stick the effect label on the conductive adhesive belt.
Press the sticker firmly on the surface of the car to ensure good contact between the conductive conductor and the copper conductor on the effect sticker.
Once your LED sticker and effect sticker (if applicable)
After in place, check if the circuit is working properly by inserting the battery and pressing the conductive tape and battery hard.
The LED should be turned on.
Congrats, you can jump to the next step to finish your car.
If the LED is not turned on, please follow the steps below to debug the FAQ.
If the LED is not turned on: check the battery polarity-
Make sure the front of the battery touches the front of the circuit.
If the battery is plugged back, the LED will not work.
If the effect sticker is used, make sure that the effect sticker is firmly pressed on the conductive adhesive tape and the polarity is correct.
If one or more LED (s)
Work but no one else: Check nonworking LED(s)-
Make sure the LED sticker is firmly pressed on the conductive adhesive belt.
Check non-polarityworking LED(s)-
Keep in mind that the LED does not work if the polarity is the opposite.
Now that your Chibitronics circuit has been arranged, attach the copper tape to the battery stand.
If you\'re using conductive (metal)
You need to create insulation between the tape and the battery.
The easiest way is to cut a piece of paper about 1 \"by 2\" and fold it in the middle.
Insert the paper into the battery stand (
Prevent circuit closure)
And put the positive and negative poles of the circuit together with the battery in the clip.
Once you have completed this step, you should do all the remaining steps to get ready for the game.
Before racing, insert the battery into the binder to make sure the battery is in contact with the copper band.
Ask your leader or track master to dim the lights so everyone can see how great your car looks under the lights!
