As well as slightly higher output voltage for semiconductor Vs tube rectifier, there is the issue of natural 'soft starting' that vacuum tube rectifiers exhibited. As it takes some amount of time for the filaments to reach operating temperature and thus allow full current flow, there was a more gradual rise in output voltage and current flow with tubes, much easier on the downstream filter caps and other components. Semiconductors rectifiers allows much higher initial current surge limited only by the impedance of the transformers windings.Lefty

IOREF. A Due board will have 3.3vdc on that same pin.
Quotei see the topic got derailedWell you never know, maybe the Due design will include some valves QuoteIOREF. A Due board will have 3.3vdc on that same pin. Good point, I guess that answers that question. Pity about the 300+ existing shields but it would be hard to accommodate them and keep the price down I suppose.______Rob
Well.. if the shields are not going to be compatible, maybe it's time to raise the 'pin spacing' issue again?
I release all rights to this specific copyrighted idea.
Well you don't have much choice, you can't copyright an idea.
but I do believe one can copyright an idea, just by writing it down
Can Copyright Protect my Idea? .......The simple answer is no, an idea in itself cannot be protected. The Chambers 21st Century Dictionary defines an idea "a thought, image, notion or concept formed by the mind" so by its very definition an idea is a totally intangible thing. In order for there to be any protection of an idea, it must first make the idea exist in some tangible way. In the case of copyright law, it is the work that realises the idea that is protected (i.e. a document), and it is the act of recording that work that fixes copyright in the item itself.
the Due is way over due (oh a new Arduino joke!)
It could be many things, chip shortages or difficulties with the cross compiler / environment are my guess.
