We found these interesting video on Youtube about winding transformer that I'd like to share with you all.
Although the methodology used is not according to our standards and practices, definitely it is something to begin with and will be useful for crude transformer building. If you follow our blog, you would have discovered that winding a good transformer actually covers more ground that this video.
On a side note, if you'd like to test or prove that you understand or know more than the video composer, do post in the comments section what is done right and what is done wrong. We shall see how good you are at transformer design.
