Precision Balance QC Suite (PB153S-compatible) - Sell Project
Project Overview
Built solo to fix a pharma QC lab's precision-balance tool that kept freezingmid-session. The old Python/Tkinter app called UI widgets from a backgroundserial thread — a classic Tkinter thread-safety bug — so it froze duringweighing, mis-tracked friability session counts (always showed "1 sample,complete"), and had a config dialog whose OK button could scroll off-screen.This is a ground-up rebuild in Rust (Tauri 2) + Svelte: serial I/O, parsing,and PDF generation all run off the UI thread by des...
