Hackathon Prizes Online / National

3×3 Grid Ratio scanner

Reward $100

Freelancer.com creative contest — guaranteed prize of $100 USD. I have a 3 × 3 keypad that accepts the digits 0-9; every press produces a token such as A3, C0, X or P. I need a small data-analysis utility that watches the stream of tokens, keeps only the most recent sixteen, ignores every P, and after each new entry recalculates the percentage ratio of letter tokens (A-F with their trailing digit) versus X tokens. A real-time visual update is essential so I can glance at the screen and immediately see whether letters or X’s dominate. Technology is your choice—Python with Tkinter/PyQt/matplotli
