Wind Your Own Transformers and Build a DC-to-DC Converter
With switch-mode projects, there’s always the problem of where to obtain inductors and/or transformers with the necessary specifications. Parts can be hard to find and expensive. So why not “roll your own?” With this project, we will design and wind a transformer and use it to get +12V and -12V from a 9V battery from the DC-to-DC converter. Kit includes an article reprint.
