R/C Hovercraft

Hi my name is Matthew and I am building a RC hovercraft. This device has two fans that enable it to move around without disturbance. The body of the device is secured and accompanied by an air cushion and skirts that go on the front and back of it so it could easily move on land and water smoothly.

Reflection

This has been a good year for me at the Bluestamp Engineering program since I had learned a lot of unique skills that could help me become a better engineer. When I started on my projects, I had met a lot of challenges and obstacles that I had overcome by searching up certain things on the internet and observing what I did wrong. There were some days where I thought I wasn’t going to succeed in doing my project, but I know that was not the case since I had eventually completed it. Ever since I came to this camp, Bluestamp has given me a better perspective of how engineers should act when they are cooperating and working with each other or by themselves. For anyone that wants to come to this camp, I could tell that this camp does not give up on you and wants you to exceed in becoming a better person not just in engineering , but also life.

BOM

Schematics

In this milestone, I had used black paint, a ruler, and a marker to produce a black fin for the hovercraft in order for it to make it look fierce.

Third Milestone

I had attached the battery, arduino, 2 ESCs, receiver, and both of the motors with tape and hot glue so they could not fall off the hovercraft when the hovercraft itself starts to move. Also during this time, I had attached a roof over the arduino so it could be secured and protected from debris coming from the hovercraft and a hatch for the wires to fit inside the hovercraft. I had installed  two motors  so that one can blow air to the cushion of the hovercraft in order for it to float and one for thrust. After this, I put black paint on top of the whole entire hovercraft, the roof, and the hatch that is on the back of the hovercraft.The challenge in doing this was that I did not build the correct roof for my hovercraft and had to redo it. I favored in adding another motor on top of the hovercraft using a screw and washer underneath the screw. I did not like that I had to solder in order to connect both ESCs to each other. For my next milestone, I am going to attach a fin on top of the roof and paint it black.

Second Milestone

STEM Summer Camps

This milestone will be about controlling several devices using a controller. I had connected the receiver and the ESC, which is connected to the motor,  to the arduino’s digital pins  by using  wires which helped the arduino read the signals from the controller to the receiver and the ESC. The arduino maps the values of the joystick of the controller into the speed values for how fast the esc is going which causes the motor to move a certain speed. The challenge in doing this is that I made the mistake of wiring the receiver the wrong way which didn’t make it blink to show that it was connected to the arduino. I had learned that ESC stands for Electrical Speed Controller. I enjoyed seeing the values on the serial monitor when I made the arduino know the information from the controller which mad both the controller and the receiver to have solid Led lights. I did not favor in switching the codes to make the motor be powered and controlled by the ESC and the controller. For my next milestone, I am going to test out my hovercraft with the motor and the other essentials to move it.

First Milestone

20180712_140708
I had created the structures for making the actual body of the hovercraft by using a ruler to measure the pieces of cardboard to make the prototype of the hovercraft. The challenge in this stage was that I had to use the ruler very carefully as to make the right measurements and I had made a few mistakes of how the pieces should fit to make up the hovercraft. Later on, I used the cardboard hovercraft to make the pieces of foam for my final version of my hovercraft and had also used putty and epoxy on the fiberglass cloth to make the body. I had learned that epoxy is a strong glue and can withstand heavy impacts. I enjoyed all of the calculations I had made when I was using the ruler and I did not like that I had to wait for the epoxy to dry up on the hovercraft. For my net milestone, I am going to connect the gamepad to the controller using the arduino.

Starter Project

The project that I have built was the Dice Kit which has several LED lights that light up from numbers 1 through 6 when the device is tapped against the table. This is caused by the Dice Kit reading the impact of hitting the table by using the piezo sensor which then enters the PCB as a voltage which is regulated by the Diode in order to protect the chip from over voltage. The reading is then read by the chip on one of its legs which the chip turns into a decimal value which causes the LED lights to light up randomly since the chip uses a randomizer. However, when the Dice Kit isn’t touched for 15sec, the chip goes into low power mode and as a result turns off the LED lights. The great thing about this is that it was easy to make and the challenge to making this device is that you have to be careful about soldering under the PCB when you are trying to flush the legs to the PCB.
