Mini DIY Adjustable Power Supply

About: Always loved electronics. I like to reuse parts or componets and I Love to be part of the Instructable community.

This is my mini adjustable power supply. It will take any DC source between 7.5V and 28V. The output will be between 1.4V and the input voltage.It cost me about £9 in parts, most of them from HK.

Please comment if you like it.
