Transformer Kit

Learn how to wind your very own step-up transformer coil from scratch with this simple kit. Great for anyone from a beginner to the most advanced builder. After all, it's great to be able to say you made something from a handful of parts. It's something more to say you made the parts too. Check out what others are saying about the DIY Transformer project build!

If you are unsure of the dangers involved with your particular project, consult with someone who is experienced. Always wear eye protection and gloves. FAILURE TO INITIATE AND FOLLOW YOUR OWN SAFETY PROCEDURES MAY RESULT IN BODILY INJURY OR DEATH!

Note: The order in which you wind the primary and secondary coils does not matter as long as the windings ratio is the same in the end. If you would like to build a step-down transformer, you would need to have primary coils of thinner wire and secondary coils of thicker wire (opposite of step up).

You Will Need:

  • Soldering iron
  • Solder
  • Calculator
  • Electrical tape

Magnet Wire, 26 AWG, 1/4 lb (328 ft.)
