How to Add Extra Windings to a Toroidal Transformer – Custom Multi-Voltage Hack

Want to add uncommon or extra voltages to a standard transformer—without breaking the bank? In this video, I’ll show you how to hack a toroidal transformer to add custom windings for multiple isolated outputs, plus a simple way to add a shield winding. This is a cheap and reliable solution for those one-off or prototype circuits where ordering a custom transformer would be overkill. And while stacking multiple transformers can work, it’s bulky and inefficient. With this method, you’ll learn how to get the features you need from a single toroidal core—fast. 🧰 What You’ll Learn: How to add custom secondary windings How to calculate the wire size and turns How to include a shield winding for noise reduction Tips for safe, easy transformer modification Perfect for electronics hobbyists, DIY power supply builders, and anyone who needs multiple or unusual voltages for a special project. 💬 Got questions?
