Five Ounce Racer - Revving Up Pinewood Derby Software in Python
summary
Python reads a decades‑old Pax timer at 1200 bps with 7 useful bits and two stop bits using pyserial, masking off the high bit; the entire reader is under 50 lines. A log‑driven simulator replays races, times go into SQLite, and a simple Django admin provides operator controls while a lightweight Flask UI shows live results. Race reruns are driven from IPython notebook and unit and behave BDD tests validate the round and lane handling.
