A Micro;Bit attached to a self made top, that will count the number of times the top spins in a circle.
I got this idea because as a child my friends and I would have competitions on who could spin the top for the longest amount of my time. In a computer science class we were required to use a device called a micro:bit, and program it to work in collaboration with another item. That is how this idea arose.
First, I hot glued the standard size marble into the center of the CD. Held it in position and waited for it dry for about eight minutes. This will allow the CD to spin, replicating the action of a top.
This is a very important, but easily overlooked portion of the project. I measured the distance from the bottle cap to the end of the CD on both sides. Next, I found the center of gravity for both of the AAA batteries and marked it. At the same distance on both sides of the CD, I hot glued the center mark of the battery to the line on the CD. This allowed for the CD to be balanced on both sides giving it the optimal amount of revolutions per attempt to spin.
