Got an LED but no driver, or your driver just died? This simple, universal driver circuit can replace almost any failed LED driver. In this video, I’ll show you how to build one with just a few common parts: 1N4007 diodes, a CBB capacitor, bleeder resistors, and an electrolytic capacitor. The output voltage automatically adapts to your LED load (from 12V up to 30V+), and you can choose the capacitor value to match the desired power – 1µF gives about 70mA, 2µF gives 140mA.

⚠️ Important: This is a non‑isolated circuit. Do NOT touch any metal parts while powered – risk of electric shock!

Perfect for repairs, hobby projects, or emergencies. Watch the full build and test! 🔧
