Haaa, well spotted. It's just a generic one but the top button fell off at some stage, rest of it still worked so I just grabbed a left over knob from my film plate build and glued it on, works great and actually feels a lot more solid to use than most shutter cables. I bought a replacement cable but it's just sitting in the bag as a safety for if this one breaks.

@@thefilmlaundry 7 different exposure stages… surely that can be miniaturised into a wardrobe sized machine 😂 Some folks long for aerochrome; me gimme that damn beautiful K-14 - in 120.
But I think a more practical project would be seeing if you can miniaturise the rangefinder mechanism on a Mamiya Super23. Won’t ever get the whole thing down to a Mamiya7 size unit, but a 6x6, 6x7, 6x9 with interchangeable backs and some of those press lenses … that’s the dream…
It came out way better than I expected, once I figured out the process it's actuyquite simple. Hadn't really thought about doing a tutorial, I will pop the 3d models up on Thingaverse, if you are going to make one, by all means shoot me any questions you have, best to just DM me on Instagram @the_film_laundry
No such thing as a silly question. Unfortunately the Instax mechanism means the film is set back a few millimetres more than the Hasselblad film back, and there's no easy way of changing this without completely rebuilding the Instax part. The focussing screen on the Hasselblad is calibrated assuming the film will be a certain distance from the lens. However the Instax film is a few more millimetres back and so unless you shoot at f22 or higher and the depth of field covers that offset, you need to either get the film closer or adjust the focus screen to match the Instax. Hope that makes sense.
Look you probably could design and an entirely 3d printer back with the eject mechanism, however the tolerances for the little catch that pushes up the exposed frame only (without accidentally pushing up multiple sheets) as well as the rollers to provide proper spread of the developing chemicals would be quite complicated, it's possible, but way above my skill level. I do remember seeing a project where someone made a manual crank to advance the film out and a push button kind of lever at the base to start the film ejecting, but it had quite a few hiccups. And for my mind, even if you got it all working it would only work exactly like the film back, so no real benefit.....and I'm lazy 🤣
About new project. I wrote you an email about my project that might interest you. But no response 😢. Thank you for the video, it is really interesting.
Sadly I sold my RB67 years ago, was just too big and bulky. I'm pretty sure there are a lot of projects already on TH-cam, it's a much easier build than the Hasselblad due to the size of the camera
Another great video. Thanks again. Did you make the shutter release cable you are using on the Hasselblad? BTW my 7 year old Bouvier says hi back.

That thumbnail is traumatic!!!
I’ll watch in morning 😂
Haaaaa, I apologise, no Hassies were hurt 🤣

Haaa don't get me started, I have seriously been looking at all the work people have been doing to figure out how to develop Kodachroma again 🤦🏻♂️

It’s crazy that you made it work, and it looks so easy to do, are you thinking on doing a step by step tutorial by any means?

A golf course and some pickleball courts would be nice there. Don’t ya think?
I think the plan is apartments and more shops 🤣
Quick question maybe silly, but if the instax film is located where film would usually be, why would you need to calibrate focus ?

Question why do you need the donor instax if you could 3d print the case and the mechanism to eject the film or is there more to it

awesome
Thanks, was definitely a bit of fun to build.

Weird, didn't get anything, must have been eaten by the spam filter, best to DM me on my Insta, they always make it thriugh @the_film_laundry
That's great. I'd appreciate it if you could make a bag for 😊 mamiya rb67.
