Inspiration

The year is 1215, revolution has ended, the future is Web3 financial dashboards with blockchain integration now. After the king was a bit of a stinky-winky, his Barons wanted to restrict his god given right to rule over us and thus the Magna Carta was born. However, there was a need to spread the message.

What it does

It Drives and spreads the message of the Magna Karta. Features:

• Fully functional 4 wheel drive
• Theoretical mobile iOS control
• Wireless keyboard controls
• Collision avoidance with ultrasound
• A slightly wobbly front left wheel
• Drag Reduction System

How we built it

• Box of Timberland's
• Electrical tape stolen from a large Spanish man
• Raspberry Pi
• 4 motors, LCD screen, ultrasound sensor, 8 AA batteries and a portable phone charger.

Challenges we ran into

• Not having done hardware before
• Pin numbers are stupid
• the LCD screen needs specific pins for some reason???????
• Eduroam is awful
• Pi for some reason had a non functioning hostname - had to get the IP every time, you know the thing that changes all the time. Working on someones hotspot, which would disconnect when they walked off.
• Thinking we blew up the SD card until we realised Windows is a non functional OS.
• Not bringing glue
• Not bringing 2 motor controllers
• The iOS app trying to control the car in a totally different way to the keyboard controls

Accomplishments that we're proud of

• It moves
• Small documentary

What we learned

• Bring 2 motor controllers - or send James on a 4 hour quest to the middle of London and back to go to our favorite sponsor of the event (video included)
• Hardware is way more fun
• Actually plan the protocol next time

What's next for Magna Karta
