This Homemade Soldering Iron Shouldn't Work... But It Does! 🤯

Can a power resistor become a real soldering iron? 🤔 In this video, I build a portable DIY soldering iron using a 10W 6.2Ω wirewound resistor, a copper tip from an old soldering iron, and a 4-cell 18650 battery pack. This homemade soldering iron is lightweight, portable, battery-powered, and surprisingly effective for electronics work. I show the complete assembly process, explain how it works, and test whether a resistor can generate enough heat to melt solder and solder electronic components. ⚡ Features: • 10W 6.2Ω wirewound resistor heating element • Copper soldering tip • 4× 18650 lithium-ion batteries • Portable battery-powered design • DIY electronics project • Real soldering test If you enjoy DIY electronics, homemade tools, soldering projects, battery-powered gadgets, and creative electronics experiments, this video is for you.
