You know that the original author pulled this of the net because it was not working the way he hoped,there have been other discussion's regarding this power supply here before,you'll have to search for them though

Actually your first upload is the newest version.your right they are good to learn with and it is a nice supply,If memory serves me I think the only problem was some noise on it,wasn't very clean voltage?
I'll see if I can find those old post.Never seen that  second one you posted look's like it was re-worked but I  can't translate the Doc so I don't know what they did regarding the Lt1491 and the lm358's.
Good upload anyway -- keep it up  ;D
