// Thermal PCB Inspection
HotSpotter turns your USB thermal camera into a professional PCB inspection tool. Calibrated temperature readings, real-time thermal imaging, and multi-camera support — all in a clean Windows desktop app.
// Features
Built for electronics engineers who need accurate, actionable thermal data — not consumer gimmicks.
Real-time calibrated thermal imaging from your USB camera. Full-frame streaming with configurable color palettes to reveal temperature gradients the moment you point the camera.
Pixel-accurate temperature measurement at cursor position. Uses proper raw sensor conversion (raw ÷ 64 − 273.15 °C) for scientifically meaningful readouts you can trust.
Works natively with InfiRay A1T, Topdon HT-301 (UVC) and Thermal Master P3 (vendor protocol), with more cameras being added. Plug in your hardware and HotSpotter handles the driver details.
NUC (Non-Uniformity Correction) support for consistent flat-field thermal accuracy. Per-camera lens configuration presets with user-editable profiles stored locally.

Maya realized then why people entrusted the stone to strangers: it erased the line between holder and teller. She left behind a short recording on a flash drive labeled with her name and the route she’d taken: a wind sound recorded from the train window, a vendor’s clapping rhythm, the musician’s tune, and her laugh as she mispronounced a greeting. The cultural house promised to preserve it as MP3, adjusted to extra quality — a small gesture, technical yet tender, that kept the textures of voice clear so future listeners would hear things they could miss at low fidelity: breaths between words, the tiny hitch of a forgotten line, the exact way a consonant softened when the speaker smiled.
