So I needed a bench supply for some arduino stuff I have been working on and so I decided to make something at least slightly elegant with my shapeoko 2.
It is all documented on my blog: http://livealittlemore.co.uk/2015/06/10/benchtop-power-supply-from-pc-power-supply/
I will just post some of the photos here and this is the video montage of the build: https://www.youtube.com/watch?v=Qb-fbTWZ688
