HEAT

🎥 Full build video on YouTube:👉 LINK HEAT is a compact, budget-friendly DIY hot reflow plate designed for SMD soldering.It’s built with easily available components, a simple PCB, and 3D-printed parts, focusing on reliability, safety, and repeatability rather than overkill complexity.The project is centered around a PTC heater, solid-state switching, and a microcontroller-based temperature controller.Instead of a full PID loop, HEAT uses a windowed / staged temperature control approach, which is simpler, predictable, and well-suited for small reflow plates.Key goals of the projectMake SMD reflow soldering accessible and affordableKeep the electronics understandable and hackableBe reliable enough for daily prototyping useLook clean and compact on the workbenchFeaturesCompact desktop hot reflow platePTC heater (self-limiting, safer than nichrome)Solid-state relay for silent AC switchingMicrocontroller-based temperature controlNTC thermistor feedbackOLED display for live temperature and
