AUDIO VISUALIZING HAT

So many people in the world are passionate about the music they listen to or the music they create. They put on their headphones and bob their head in sync with the music. Passers by watch these people enjoying their music but never know what the person is actually feeling. This AV Hat is a wearable device that music listeners can hook up to their headphones. When the headphones take sound input, they convert that audio to video on the hat, creating mesmerizing patterns in sync with the music. This is a fun way of being able to share your music with the world without actually making people listen to it. The perfect place to wear this hat would be at a concert or a nightclub where it takes in audio from the surrounding music and lights up in crazy patterns!


THE PROCESS

Made a 4 by 6 LED matrix:
1. Center square:orange LEDs
2. Middle square:Red LEDs
3. Outermost border: Green LEDs

For the purpose of coding each individual LED to create patterns, we split the rows and columns as follows:




We cut open a hat, taped the wires to ensure they are tightly fixed and then hid the entire circuit board inside the hat.

THE ANNOYING PIANO CLOCK

We have all had days when we cannot seem to get out of bed and just keep snoozing our alarm. The annoying piano clock avoids just that. It plays a simple tune over and over again, till you actually press the piano keys on it and recreate the same tune. If you do not recreate it exactly the same way, it will go on ringing. So annoying! This alarm clock is meant to help sleepy-heads get out of bed and have a little fun while turning their alarm off.



THE PROCESS

First, we set up the real-time LCD display



Next, we wired the LCD, buttons and speaker



We then coded in Arduino to display real time and an annoying message



Put together the casing using cardboard, hot glue, tape and lots of cutting

TIC TAC TOE - The wrist band

Tic tac toe is a simple, entertaining game that people can play at any time! It is a great stress buster. My team mate and I wondered what it would be like to have a wrist band with colorful LEDs that let you play the game on the go? We decided to use blue and green LEDs to indicate the two players. Each time a player touches his colored LED on the surface of the band, the LED lights up. Whoever gets 3 same colored LEDs in a row first, wins!
A major application of our game targets senior citizens who over time, reduce movement in their fingers. This band is a portable, light and entertaining wearable for them to play the game and they can play with friends, kids, grandkids and so on. The best part is, you can invite anybody to play the game with you and even make new friends that way!


THE PROCESS

Components used:
• Perfboard
• 9 bi-­colored LEDs
• Acrylic sheet to make the touch pad
• Resistors
• Wires
• Sticky tape


First,we wired up the 3 x 3 LED matrix onto the perfboard



We then made the touch pad by taping the rows of the LEDs, taping the columns of the LEDs, insulating each intersection and soldering the rows and columns to long wires and then we assembled everything
