Bluetooth Weighing Scale

Inspiration

I am a cofounder of an app that has a thousand users, which is used by many to log their meals at Purdue dining courts, so I believe this would be helpful to improve the accuracy of their logging.

What it does

Its a bluetooth kitchen scale, theres nothing more to it.

How we built it

We were going to use a load cell, but StarkHacks didn't have any, so we resorted to utilizing hooke's law. It uses springs and an ultrasonic sensor connected to a Rubik Pi 3 to accurately measure the weight of an object.

Challenges we ran into

I don't know how breadboards work, and it took me over 6 hours to get the wiring correct.

Accomplishments that we're proud of

I got it working!! (until i put it in the 3D printed case, then it got cooked)

What we learned

Submit 3D prints early to hardware hackathons, far bigger tolerances

What's next for Bluetooth Weighing Scale

Making it more scalable, actually implementing BLE support, adding BLE support to my app
