A soldering iron made from a KD366 transistor and a buck converter! ⚡ Revolution or nonsense?!
Why buy expensive equipment when you can build a powerful soldering station for desoldering SMD components yourself? Today, we'll use a powerful KD366 bipolar transistor as the heating element. To ensure stable operation and prevent overvoltage, we used an LM5116 step-down regulator. We connect everything to a laptop power supply, set the parameters on the volt-amperemeter (1.9V / 7.00A), and watch pure physics in action! The solder turns into liquid in seconds. WARNING!
