Too bad that it does not control the temperature for color film work.

@Old Gregg - Thanks for the type remark - already fixed. For Paterson tanks - they have cone shape and have tendency to ran out on higher speed - they were not designed to be used in rotary. Rubber band is the easiest thing I come up with to keep them in place. I ran many many hours of testing and it never failed. In Patterson tanks the weak link is the lid. I may see that it may slip off if it is very old / loose, but I never experienced that issue.

@Sirius Glass - temperature control will make it completely different machine, much bigger, complex and expensive. There are plenty of Jobo and similar machines around for that purpose. AuRA was designed to fill the gap between manual development and more expensive machines offering features that many of these machines do not have. I tried to make it reasonably simple, affordable but still a little bit profitable - this is my first commercial project of this kind.
C-41 - I do it exactly the way Old Gregg explained. I live in Phoenix, AZ and my normal house temperature is about 80F / 27C. In my case temperature drops top 100. Never had bed results.

Looks very interesting Victor. It is much more refined than the Deseler rtary agitator I use for a similar purpose.
I've moved this thread to the Darkroom Equipment sub-forum, and will close and delete the duplicate thread you started there.
Good Luck with your Kickstarter.

In this class of processors, that only handle the agitatin of a tank, we already got the Heiland TAS. The programmable processor yields both inversion and rotation in a combined movement. Also it can handle both cylindrical and rectangular tanks. But then its price is about 4 times that of this Aura processor.

Wow- that was quick! I have old Beseler and Unicolor bases- quite primitive compared to your new machine. Clearly there is a market for reasonably priced new darkroom accessories like yours. It’s great that it takes the Paterson tanks.
