Midtone Machines film processor

Not sure if this has been posted before, but here is a (another) potential new film processor. Out of New Zealand from an aerospace engineer who apparently recognizes the primacy of good midtones, always a good sign.

As always, the odds are stacked against anyone developing, manufacturing, and marketing a viable and superior processor in today’s market, but this project seems better thought out than the Filmomat, to me at least.

Only posting in case someone might find it interesting, as he doesn’t seem to have much exposure here.
There are internal links on the homepage which gives more information on the thinking behind the design.

One always hopes for the emergence of the better, and/or more affordable mousetrap.

Hey all I'm the 'creator' of Midtone Machines, got word that there was a thread here talking about it so I made an account. Thanks for the interest! If you have any questions I'm happy to answer them in the thread.

Currently designing two PCB's to act as an interface between the arduino controlling the whole thing and all of my motors, sensors etc. I was considering soldiering on with the mess of wiring I currently have but eventually decided to not waste time and go to the design solution I intend to end up with, it will take more time in the short term but I'll end up ahead in the long term.

New update on my website:
http://midtonemachines.com/news/pcb-design/

Nearly finished with the custom PCB design I'm going to use to replace the current rats-nest of wires and bring the machine closer to the final production version.

Looks great. Just a thought, on your breakout board make sure you have it on standoffs or some other way of raising it up. Don’t want an accidental leak submerging it.

Yep it's going to be on standoffs, you're right I've thought about the possibility of leaks and so I'll be making sure that everything electronic that isn't fully sealed is well above the base plate. I might also look at some kind of splash cover for it in case there's a spraying leak (although I think that's less likely, the pipework will hardly deal with any pressure).

New blog post is up, PCBs are finished and working fine, also put together a quick laser-cut MDF body shell for prototyping that IMO looks pretty good.
