In order to help keep pedestrians, cars and longboarders' safe, we can add turning signals onto the longboard to help others know where the rider is headed to next. Also, who doesn't want to light up the night in style with LEDs?
What it does
Our longboard connects wirelessly to a pebble and an android app. It is able to change different colors based off of the commands. We also integrated safety functions to make longboard safer.
How I built it
We built this at Hack ISU with a great deal of 3d printing for the gears that connected to the truck of the board. As a group we had 2 Software Engineer and 2 Electrical Engineering students. We put LEDs on the side of the board and used a small 5V battery to power the project. In order to get a high enough voltage from the gear, we had to in cooperate an OP amp. This allowed us to get cleaner analog read voltages.
Challenges I ran into
We had major issues in the issue with 3d printing and we had a very small knowledge base. We had issues with the lightrail() function that related voltage to speed. This involved alot of math.... we got it though.
Accomplishments that I'm proud of
We have a finished project that incorporates an app, and lots of hardware such as motors, op amps, arduino and digital leds.
What I learned
We learned what a great deal of energy drinks, lack of sleep and intense amounts of concentration can do to a human being.
What's next for The Boarding Firefly
We are going to be lighting up JOHHHNNNN CEENNNNNNAAAA!!!!!!!!!!!!!!!!!!!!!!!! Blaring Horn
