Re: Midtone Machines - Automatic Film Processing Machine
Another new blog post, new company logo and some website updates: http://midtonemachines.com/news/new-...-and-progress/
The machine is now fully capable of processing B&W, I'm actually starting to run out of things to do on it now, so I'm going to have to start doing the boring things like making a BOM (bill of materials) to figure out how much it actually costs to make one...

RE: Name, why not something that pays tribute or homage to what it was originally based off aka Phototherm.

Well maybe Burns-O-Matic, :o
Midtone Rapid Color Processor

Midtone RFP-4? (rapid film processor 4, for 4 rolls of 35mm per tank)

The first version of the Phototherm was the FP-1, although rapid kind of implies something like a x-ray film dev process.
Re: Midtone Machines - Automatic Film Processing Machine
I'd say something simple like Midtone Machine AFP-4
Re: Midtone Machines - Automatic Film Processing Machine
New blog post up and new name for the machine, it's now officially the Chromabox-4
I'm struggling with my ancient 3D printer while in isolation so I'm looking for suggestions for when I'm able to shop online again, let me know if you have an idea of what printer I should get!

Re: Midtone Machines - Automatic Film Processing Machine
Leaking valves. 30 years ago when I was still working as a chemist we did a lot of manual titrations. Teflon stopcock Pyrex burette. 1/10 molar HCl never seeped around the stopcock. 1/10 molar NaOH just wouldn't stay in the burette, after about 30 minutes you would see some leakage, if you left it over the weekend, we would come back to a crust of dry sodium hydroxide around the joint.
I have tanks with floating lids dilute working solution of hypo clearing agent, doesn't leak through the self closing tap, if I try to store the 5X concentrate it seeps and clogs the valve. This stuff is mostly sodium sulfite solution.
Re: Midtone Machines - Automatic Film Processing Machine
Managed to print enough valve parts to retrofit the prototype and the leaking is gone. I've also got the heater systems up and running nicely. Here's a really short teaser video of the Chromabox-4 in action, cycling through 6 different 'chemicals' one after the other. What you don't see is the automatic water and air flush cycles that happen between different chemicals to prevent cross-contamination (which would have been visible in the video as colour contamination between the different bottles).

Re: Midtone Machines - Automatic Film Processing Machine
Chromabox-4...? Hmmm not feeling it, let me know when you produce retrofit tanks for Phototherm machines
