Hi, I'm glad you didn't build the 5Volt regulator the way that instructibles did, with the parallel LM7805.
DON"T...This is not the way to get extra current handling from a linear regulator, in fact if your power supply is powerful enough and there is no fuse on the regulator input, it could get explosive.
(Tried it one day as an exercise.Bang, bits everywhere, quite impressive, then measured output voltage, it was at unregulated input level.)
In fact I'd be very careful of any of that project.
[soapbox] I worry when a project is more about 3D pictures, than the project itself, and no circuit diagram, and that regulator circuit. It shows how little research has gone into its construction.[/soapbox]
