Rest assured that Mike Caswell and I are in no conflict here at all. As a matter of fact, it was Mike that involved me in the first place, because you guys were having so many problems. Contrary to what some may think, Mike does care, and he intended me to be the vanguard of the solution.
I can't think of a nice way to say this so I'll just say it; nearly every set of instructions on small scale or hobbyist anodizing that you'll find are incomplete, technically flawed, or just plain wrong. It appears that the authors found one of many recipes that happened to work for them, and then never bothered to figure out why it worked. If its any consolation, you would be shocked to know how few professional anodizers actually understand how and why their process works. That said, LCD does work. If dyeing quality is of importance, LCD will outperform conventional techniques, even those used by pros. But should you choose to anodize at conventional current densities, the simple and very effective mathematical techniques explained in LCD will work equally well.
Power supplies that are battery substitutes are not generally fully adjustable, which is a drawback. You will need to provide information on the maximum size part you intend to anodize, and some idea of it's total surface area before I can advise on the size of power supply you will need.
The idea that anodizing is somehow "self current limiting" violates Ohm's Law, and hense is wrong.
