From the project
flico 是一台以 Raspberry Pi Pico 為核心、用來量測螢幕 / 光源閃爍(flicker)的小型自製 儀器。光訊號由 Vishay BPW34 矽 PIN 光二極體接收,經 Microchip MCP6004 跨阻 放大器(TIA)轉成電壓,由 Pico 的 ADC 取樣後,透過 USB-CDC 串列傳回桌面端的 Rust GUI(eframe + egui)即時繪出時域波形與 FFT 頻譜。

- 螢幕 PWM 調光的可見化:筆電 / 手機 / 顯示器低亮度下的 \~200 Hz–25 kHz PWM 閃爍, 用肉眼看不到,但會讓人疲勞、頭痛。 - 日光燈 / LED 燈具的 100 Hz / 120 Hz 漣波:確認照明品質。 - 遮蔽測試:用手指、紙片在 BPW34 前面晃動,即時看 ADC 訊號擺動,驗證整條訊號鏈。
