Inspiration

After winning last year’s Miami Hack Week, we thought of what we could do to top minting an NFT in space via a Hot Air Balloon. What about personally minting an NFT while skydiving? We consulted Delnoza, who talked about her experiences skydiving. We did what any Miami Hack Week hacker should do and asked what problems we could solve for her. During her tales, she talked about how once someone crashed into her, breaking her pinky finger. We then thought about how we could avoid collisions in the future, and realized that an IoT device can determine how far it is from another device. If two or more skydivers have a device, they can then tell how far they are from each other without having to visually locate the other person.

What it does

The main function of SkyHack tech is to determine how close another skydiver is and how fast they are approaching to avoid a potentially fatal collision. When the device detects that other divers are a safe distance away, the OLED display flashes green. When the device detects that another diver is getting cautiously close, the display flashes yellow and the device starts to vibrate. When the device detects another skydiver is dangerously close, the display flashes red as a warning while providing also providing rapid haptic feedback via vibration motors. Our can also device let skydivers know when to jump out of the plane and deploy their chutes. Additionally, we can determine: What skyding group you’re in The Plane ground speed What speed you’re falling at What speed you’re traversing horizontally at What direction you’re heading in, horizontally Your altitude

How we built it

We built the devices using an ESP32, sensor fusion of 2.4GHz transceivers, an accelerometer, altimeter and other input parameters on each device while providing both visual and haptic feedback via OLED displays, LEDs and vibration motors. The devices were powered using 3.7V LiPO batteries
