While my DIY fixed voltage power supply has been a mainstay on my workbench, its options of 3.3v, 5v and 12v have been a little lacking as of late. It's time to make a variable voltage supply to provide more power options for my projects. This solution is capable of providing 1.2v to 14v and is easily upgradeable to around 30v if need be.
