Introduction: Mini DIY Adjustable Power Supply

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.

Me too, I've been looking for something like this for ages! Can you post the schematic so I can gather some bits together?

jpattison72 (author)2014-02-26

This looks great. I'd love the instructions to make one

newtonn2 (author)jpattison722014-02-26

Thank you jpattison72. I took some pictures as I was making it, so I'll be making the instructable soon.

newtonn2 (author)2014-02-26

Hi Granzeier, That's a fair point. I'll do that on a separate instructable. This one is just to show the unit.

Granzeier (author)2014-02-26

Nice power supply, but this does not instruct people.

How about posting the schematic diagram as step 2, and how you put it together as more steps.

More info on this cool looking device, please.
