The purpose was to create an octave and have the ability to play it when a crocodile paddle was pressed. I made this device because I like music and I thought the ability to control the sound with your feet would be cool. This project is to preform the function of entertaining people while acting as a giant piano. It will entertain because it will be

unconventional on how it is played and the sounds that will be produced. I built this project out of cut 2 X 4 ²s, springs, buttons, 5/8 inch drill bit, drill, screws, screwdriver, wires, 8 5/8 inch X 7 inch bolts, nuts, and an arduino. Next I drilled 5/8 wholes in pairs of the 6 inch boards. I did this by mesuring 2 inches from the top and 2 from the sides to place the hole at one end of the board to make a lever. The project was mostly a success. I was proud of how well the buttons worked, but I would of soldered the joints better to the buttons and shortened the length of the 6 inch 2X4 ²s to maybe 4 inches to flatten out the design. I would also paint the project to make the 2X4 ²s look nicer. Other then the sizing and design the mechanics of the project couldn`t of worked better. If I was to do this project again I would definitely look more into force meters so I could make a totally flat platform to stand on. Another thing I would change is the use of a partner because the work load was fairly heavy for one person to handle. There was not only the building of 8 switch/steps to make but I also had to code for each one to work. And to expand on this project I would try to use clear materials I could light up with leds in coordination with the buttons being pressed. This would trigger music and a visual show. I would also like to find different sounds and incorporate a melody function to allow for multiple notes to be...
This project fits more for custom made battery casing that can have more space to hide things inside. This switch with few alterations can be used for any other project as well but is designed based on e-bike needs! This project use a clever functionality of....
The circuit described here uses ultrasonic oscillations and operates based on the propagation velocity of these oscillations in the air. Thus, we can easily determine the distance of two points if the time within which the wave travels this distance is....
Sometimes the precious metals are hidden too deep and are not detected except with complicated devices. In many cases, however, small pieces of precious metal buried near the surface can be detected by relatively simple means. Everyone is very attractive to....
Many times for various reasons we forget or can not water the plants that we have in our homes. And many humidity sensors units just notify us with a beeping sound or with a flashing light, that the pot needs watering. But what if we are away from home? This....
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere. With the....
The sub-harmonic bass generator is a sound producing unit for guitars. The sound it produces looks very much like that of the bass guitar. The octave generator is sometimes quite unusual since it does not produce any of the usual ways of coloring the sound,....
In the past the sounding (sea bottom measurement) was done with the "bullet", that is, with a heavy lead object that the seamen plucked into the sea hung from a calibrated rope. As soon as the "bullet" reached the bottom, the depth appeared directly from the....
This Amplifier was designed to have the following specifications: Distortion less than 0.1% at full power of 100W even at 20KHz. Power has to be attributed to an extended bandwidth. The output transistors must be protected against short circuits. The power....
A series of LEDs serve to alert the gardener when plants need water. Using two conventional digital integrated LEDs and a series of LEDs, we make a very useful device for gardening. The device detects the amount of water in the pot and alerts the grower.....
