Story

What is Dana Ball?

Dana Ball is a game with no rules that merges wrestling with basketball. It is played with a plastic toddlers basketball hoop in a carpeted living room. Our team discovered this unique game upon interviewing Issac Yi, whom our project is specifically designed for. This project is a part of an assignment in which our team was asked to create a hyper personal product for a specific person that meets his or her individual needs.

Finding a Client

We posted on UC Berkeley's Free & For Sale page, a Facebook group of +28,000 people. Our first post listed time commitments, but was vague about the end product --it received almost no responses. The second lost took a different approach by using catchy buzz words and listing no time commitments --it was a success! We received 22+ likes and countless messages. The first person to confirm 2 interview times with us became our client.

Interview

Issac Yi is a 4th year Computer Science student at UC Berkeley. In our 1st interview with him, we found out that Issac is perpetually late, likes to work out, enjoys the outdoors, and works at a start up in Berkeley. We also found out that his friends and him play a sport called Dana Ball. This game fascinated us and we wanted to create a product that would legitimize this fight-club-esque - indoor - wrestling-basketball game.

In the 2nd interview, we focused on Dana Ball. We learned that the sport is been played by 5-6 of Issac's friends since 2012 when they first moved to college. It is played in one of Issac's friends living rooms and they regularly get carpet burns from the game (which they do not mind). Not many points are scored during each game, and the duration of each game varies.

Prototyping

1 / 2 • Design Sketch

We wanted to create a basketball hoop that reacts with light and sound when scored. Our beginning circuit included a RGB LED, Piezo Buzzer, Ultrasonic Sensor, and an Arduino Uno. The Arduino was programmed to play a Daft Punk song while flashing light when the proximity sensor senses an object closer than the set distance (35cm).

Our initial design involved 30+ RGB LEDs, but we decided to use a RGB LED strip instead because of problems with wiring and powering. We also added a 12V 1 Amp Power supply to power the RGB LED strip.

Prototype with a RGB LED strip

Step-by-Step Making

1. Get one Arduino Uno, one Piezo Buzzer, one Ultrasonic Sensor, five feet long RGB LED Strip, three transistors, and one 12V 1A Power Supply.

2. Follow the Circuit diagram and connect all parts.

3. Drill and cut parts of the hoop to install the electronics inside.

4. Attach the RGB LED strip onto the hoop.

5. Upload the Arduino project.

6. Plug in the power source.

7. and Dana Ball!
