Hey guys! In this post, I'll be talking about my hardware and it's program. There will also be a pop quiz near the end of the post. I didn't have a video for making the hardware, so I'll have to explain it with pictures.

HOW THE PROGRAM WORKS

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 The program is way too complicated to explain entirely. There are little bits of writing that describe the program. They are called "comments." If you want to make a comment, you use "//" at the beginning, like "// This is a message." Another way of making a comment is using "/**/" like this, "/*This is another message.*/" If a user were to open up a game's code, there might be comments in the program. If they were to make a mod for the game, the comments would help them with different lines of code!

If you are a fellow programmer, you would know what a variable is. A variable is used in a program to store information, like a container. If there were no variables, it would be a lot harder changing the numbers in the program.

Here is a picture of some of the code. The three variables in the circle represent the LED's. The variable "int power," controls how bright the LED's are.

WHAT ARE TIE POINTS?
~~~~~~~~~~~~~~~~~~~~~~~
The tie points are used to connect with the wires, LED's, etc. The breadboard has 830 tie points. If you saw the diagram for the circuit, all of the wires are connected with LED's and UNO R3. When the program was finished, I found out that the circuit can only work when it's connected to the computer. It was dark when it was on, so the lights were kind of bright.

 Anyway, here are some pictures of the program working.

Racing to the Finish! : Part 2

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
Hey guys! In this post, I'll be experimenting a bit more with my race car, and I'll be talking about the fastest cars in the world!

CAR EXPERIMENTS

~~~~~~~~~~~~~~~~~~

Many things can be tinkered with, even cars! There were four experiments, the trick, grip, power, and strength experiment.

I started with tricks. It involved the large wheels, small wheels, and the axle attachment. When I put the parts on, I just had to turn the axle around 3-4 times. The car was moving fast enough to do a wheelie.

If you are wondering how it did that, the answer is Torque. Torque means "Moment of Force." When I added the axle attachment, the car accelerated faster, that gave it a lot of torque. The more torque you have, the more it accelerates. It went so fast, it did a wheelie!

The grip experiment was a weird one. I just needed wax paper, tape, and a measuring tape. First, I measured the wax paper so it could fit on the large wheels. Then I taped them together to put them on the wheels.

 The Tinker-zine said my car wouldn't move. However, my car went further with the wax paper. It had to do with Friction. Friction is a force of motion. It kept my car moving on the road. With the grip strips, there was a lot of friction. When I added the wax paper, there was less friction.


For the power experiment, I only needed my race car and a measuring tape. To start, I turned the rubber band 2 times, and wrote down how far it went. I repeated the steps, but I turned the rubber band 4 times for the second try, and 8 times for the third. For the first try, the car went 22.5 inches. The second, 7ft and 1 inch. For the third, it went as far as the tape could go, up to 25 ft!

How come it moves more when you turn the band more?The more you turn the rubber band, the tighter it gets. That caused the car to go faster when it got released.

The strength challenge was really short. To do this experiment, I needed some batteries, a fruit roll-up box, thread, scissors, and of course, my race car.  I needed to make a sled for the batteries to fit in, so I got the box, and cut it into a sled shape. To drag it behind the car, I got some thread, and poked a hole in the bottom of the sled, and tied the thread to it. Then I tied the other end in one of the slits to attach the sled. For the experiment, I turned the rubber band 1.5 times around the axle. The experiment started out with the sled being empty, the car went 3 ft, 3 inches. I added a AA battery to it, the car went 2 ft, 4.5 inches. When I added a AAA battery, the car only went 1 ft, 2.75 inches. Finally, with one AA and two AAA batteries, it went 1 ft, 2 in.

I tried to add more batteries, but it couldn't move! Race cars have to be made out of light materials like aluminum so they can move fast. If they were heavy, they would move really slow!

FASTEST CARS EVER!!!!

~~~~~~~~~~~~~~~~~~~~~~

These cars can travel at amazing speeds, each one better than the last, all made by the same guy! His name was Richard Noble. The first car he made was the Thrust 1, but he sold it for parts to make the Thrust 2. It can travel up to 633 mph.

Thrust 2

That record would've been great to keep! But he wanted to create something faster, the Thrust SSC. (Super Sonic Car) He broke his own record with the Thrust SSC going 763 mph. The car actually produced a sonic boom!

Thrust SSC

Richard is still planning to go faster, he and his team are making the Bloodhound SSC. It's still a work in progress, but they plan to make it go 1000 mph!! That would be cool right? There are many people trying to break this record, but I bet that Richard is going to beat it first.

Hey guys! In this post, I have the speed video for my race car, and I'll be doing some upgrades to it.

FAMILY CARS AND RACE CARS

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Different cars do different things, but there is a BIG difference with race cars. Family cars don't have to be fast, and they can be pretty heavy, but they can hold a lot of people. With race cars, they have to be light, speedy and aerodynamic. These kinds of cars don't have a lot of space in them, so only one person can fit. Race cars are pretty thirsty cars, only going 2-3 miles a gallon. They also need parachutes to slow them down! Last of all, race cars take years to control the car perfectly, make a wrong move, and you'll go flying!

CAR CHANGES
~~~~~~~~~~~~~~~
As you saw in the video, the race car was moving perfectly, but there is an option to Tinker with the car. There are different wheels to put on, an axle attachment, changing the length of the car, or changing the rubber bands place.

Changing the car makes it move different. For example, the axle attachment makes the car go further. Changing where the rubber bands is also changes how far the car goes. If it's further away from the axle, it wouldn't go as far. But if it was closer, it would go further. I think the length of the car changes how fast it goes, like the axle piece.The wheels are probably for how much drag the car has. When I changed the wheels, it slowed the car down a bit. If you experiment with a car like this, you can make it go fast, fast, FAST!

Oil + Water = GROOVY! : Part 2

/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\
 Hey again guys! In this post, I will show you how I made my Dense-O-Meter, and I'll also talk about emulsions.

MY DENSE-O-METER

~~~~~~~~~~~~~~~~~~~~

A Dense-O-Meter is a jar full of different types of liquid on top of each other. Whenever you drop a small item in it, it will either float on the top, or sink into a level of liquid. The level it sinks to is how dense the item is. (If you haven't seen the last post, density is the compactness of an item.) If you want to make a Dense-O-Meter, you'll need.....

- A Large Jar or Container

- Honey

-Light Corn Syrup

- Real Maple Syrup (I didn't have this)

- Milk

- Dish Soap

- Water

- Vegetable Oil

- Rubbing Alcohol

 (My Container was too full for the Alcohol)

- Food Coloring (Optional)

- Scotch Tape (Optional)
- Marker (Optional)
- Pipette

Once I got my jar set, I started adding the liquids one at a time. With the honey, corn syrup, and milk, I poured them down the center of the container so the liquids wouldn't mess up the other layers. The soap and water were a challenge. I had to squeeze the soap down the side of the container. The water was colored with food coloring to give some color to the Dense-O-Meter. I used the pipette to squeeze it down the sides so it wouldn't mix with the soap. With the oil, I just poured it down the sides, like the soap.

To test out the Dense-O-Meter, I got a washer, a carrot, and a plastic model of the Eiffel Tower. Here are the pictures of the Dense-O-Meter.

Density Levels

Density Level Labels

 In the pictures, you can see the washer in the honey, and the Eiffel Tower in the corn syrup and milk. Where's the carrot? If you check the dish soap level, you can see a bit of orange. The denser the item, the lower it sinks.

All items in dense-o-meter.

EMULSIONS
~~~~~~~~~~~~

We all know that oil and water don't mix, but how do we have so many things that have oil and water mixed in? The answer, is using an emulsifier. Emulsifiers are like magnets that attract both oil and water, that's how oil and water can mix. We can make certain foods called "Emulsions," like dressings, mayonnaise, and ice cream! They use emulsifiers to mix the oil and water  together. After a while, the oil and water might separate.There are many emulsifiers like egg yolk, tomato paste, Dijon mustard, etc.
