As an engineer or curious mind, you probably have the constant urge to tinker around and build things. This simple project could help satisfy your endless need to build, and could quite possibly save a few appliances from being dismantled instead. Navin Khambhala, a YouTube designer who builds all sorts creative projects recently made a how-to video about how to make your own ‘hoverboard’. Despite the name not being accurate whatsoever as to the function of the machine, rather it is a balance board, the project is actually quite feasible and functions rather well.
The ‘hoverboard’ is made up of a few appliances that are incredibly easy to find. The main structure is made out of wood which houses all of the electronic internals. Two electric motors are then directly mounted to the board and are connected to two batteries. Instead of spending a large amount of money buying specific batteries, Navin discovered laptop batteries function exceptionally. Two switches are then used to turn the individual motors on.
(Keep in mind this is based on my design. Get more if you plan on building a stronger, or larger scale hoverboard)
- (x6) 6″ Iron Railroad Spike. (Could you believe all they use these for now is for antiques and knife-making faires. I don’t think railroad companies even use them anymore!)
- 300-400′ enameled copper wire(AKA: Magnet Wire) 20 AWG (I would suggest Remington Industries for this)
- Wire Strippers (duh!)
- Duct Tape (You can never have too much duct tape)
- 50 D Batteries. DO NOT: get power saver batteries or anything that the package says “longer lasting” this means it uses less energy than regular batteries, and you’re going to need a LOT of energy. (and yes I said fifty of them, not a typo)
- A Standard Skateboard (I would suggest Tony Hawk skateboards. That’s what I based my measurements on.)(Also, make sure its one you’re not afraid to dismantle)
- A Non-Conductible Base. (Large enough to fit three skateboards side by side) DO NOT: use a floor as a base. this base is meant for maneuverability so you could take you hoverboard to test in different locations.
- 16 small screws. (I used the screws that were already on the board(plus another board’s screws). I would recommend getting iron screws that were that size if you can find them)
- Screwdriver (Again: Duh!)
- Electric Drill. (I’ll explain later)
- Battery Holders (Same amount as the amount of batteries your getting.)
12: Measuring Tape (For measuring. I don’t think a really need to point that out do I?)
13: Hot Glue Gun (w/ hot glue sticks obviously)(yes, you need this AND the duct tape)
What is a Hoverboard and How does it work?
Our quest for faster and simpler transportation will always be a Journey and not a destination. One of the trending and sought-after modes for an individual is a Hoverboard. They are self-controlling two-wheelers which run on batteries (Well, most of them). These dumbbell look-alike Hover boards first appeared in the “Back to the Future” in 1989 but they came into existence and became popular few years back. Even though the Hoverboards in use today can’t “Hover”, they are very interesting when it comes to understanding the application of various sensors. They are also called Self-Balancing Scooters.
Before getting started on it’s working, let us first learn about 9-axis sensor. They include Accelerometer, Gyroscope and Magnetometer; all three sensors have 3-axis each.
Measures Position in Linear 3 dimensions (Cartesian Coordinates) using variable capacitance. Here, we have capacitors for each dimension where one of the plates of capacitor is kept constant and other is allowed to vary its position (They are very sensitive to change in position). The change in distance between these plates will cause change in capacitance and thereby, voltage, giving us a quantifiable value we can monitor and use it where needed.
It’s the most important component, so much that the other name for this vehicle is ‘Gyro scooter’. Gyroscope basically measures Angular change by shift of mass within the gyro. A mechanical gyroscope consists of concentric metal rims with a rotor at the center while an electronic gyroscope, which is used for most applications including this one, is a little different. It uses Coriolis Effect: when a mass is moving in a particular direction with a particular velocity and when an external angular velocity is exerted whose axis is perpendicular to the motion, then a Coriolis force will occur which will be perpendicular to both, causing perpendicular displacement of the mass. This displacement will cause change in the Capacitance and thereby, Voltage giving us a quantifiable value corresponding to a particular angular rate.
It measures magnetic field with respective to earth’s magnetic field by using Hall Effect principle. Although, we haven’t included this one in our list of components below to make your own Hoverboard.
How to make the hoverboard from the Junk Material
- Our aim is use make the hoverboard. For this purpose, you can make the use of the old junk material. In fact, by using the junk material your purpose has fulfilled and the waste products are recycled. This, in turn, is useful for the environment. Therefore, you can take the motor and the batteries. Use the metal frame to get the shape of the hoverboard. Further, with the help of belt attach the metal sheet with the motor to provide electricity. You can use the inverter that can place on the metal sheet so that you can stand on the hoverboard.
- In fact, gyroscope sensor is necessary for the hoverboard. Without the gyroscope sensor, it is not possible to keep the balance on the hoverboard. Apart from the gyroscope sensor, you can use the small wheel to provide balance to the hoverboard. Another important thing is the hoverboard is the missing breaks.
