Thoroughly enjoyed this Jenny- no idea how the algorithms sent this to me, but I’ve just bought two super 8 cameras, so maybe that’s why. I’d love to be able to have the choice of shooting film and digital on them both. Good luck with the project 👏🏻
I just had a sneaky idea how to trigger the record function on the Rapsi: Point a LDR or photodiode at the little screen you're planning to shoot the back of, as there should only be light entering the film gate when the Super-8 camera is actuating its shutter and there should be enough light scattering into the space inside your digital cartridge to pick up.
Thanks so much for that, it's really appreciated! The cartridge is an ongoing project, so watch this space for more. This channel really is what's on my bench at a particular time, so I take forays off in different directions from time to time.
Love this project. No doubt I'll spend the evening on eBay looking at super8 cameras. Maybe the carrier could be adjustable with a couple of screws accessible from inside the cartridge. Left/right forward/back to tune the focus?
Thanks :) Always worth looking at second hand shops, so many online sellers seem to think they're made of platinum and very rare (They aren't). The carrier is adhustable with a couple of screws on slides. It's not perfect. The real problem is the film gate assembly.
Hi, is there any way you can make one for my camera? I've had one for years and I want to keep using it. It's a Keystone XL300, I'd appreciate your help. Regards
Why don't you take off the UV-lens, from the picture-sensor? That will make the sensor less thick. Then add an 'after-market' UV- lens onto the outer objektive. This should work, you will get this one Millimeter off, you needed for proper projection of the images. The quality of the video you will get, should be like 'with the UV-filter' again. Hope you can finish your project. Sorry for my bad English, it's not my native toung, ... ! Greeting from Germany, Markus (db9pz) - my Ham radio call
Imagine the sensor as a glass box a few mm thick, with the light sensitive chip on its back wall. The UV filter isn't the issue but those few mm, they're enough to put the sensor outside the focal plane.
Thanks :) I should add, that's only a subset of the collection of Super 8 cameras I've amassed. It's necessary, because the cartridge has to fit every camera I can find.
funny i saw your Single-8 video first and then the part 2 of this series and now this one ... 🙂anyhoots, if the tiny size of the video sensor is too hard to fit within the camera's gate exactly, then why not use a slightly bigger sensor that would fill up not only the entire gate area, but also go further around it to make sure at least part of the sensor fills up the gate fully!? i know already this could not be the perfect solution but it might be a good new starting point? after all, some DSLR cameras already use this little trick for a number of reasons ...
i'm also thinking that extra empty space in the digital cartridge can be used for quite a number of things ... 1stly, sound recording circuitry can be installed there ... or extra battery to run more power-hungry micro computers and sensors and so on ...
The intent is to replicate a silent cartridge, and let the filmmaker record their own sound. Sound recording in the cartridge is problematic, often there's no way to get the audio signal into the camera.
@@jennylist yes i know about that ... but as you have demonstrated that yourself too, the slight adjustment to the lens trick that works but also turns it into a macro lens instead of a 'normal' one, can now be applied to the sensor itself, by means of some screw / volume thing moving a tiny plate holding the sensor back and forth for fine tuning its distance from the gate ... after all, with some output signal taken directly from the sensor cartridge, its image can also be viewed on a separate monitor outside the camera's cartridge chamber, right? 🙂
if you make the sensor mounted in a way that you can put sheets of paper below it, you can use them to micro adjust the distance. A sheet of paper is 0.1mm thick which is probably the closest you will get in tolerances anyway out of a 3D printer. It might help you dial it in. :)
I've seen it done on cameras where the filter is a plastic film, but this one appears to be the glass. Of course, there are many different camera sensors out there.

I know you make millions and millions of dollars doing such a business like this even for many independent film studios using Super 8 film cameras. Think of all the great movies they might make.
I don't think for an instant that such a business would be successful,. There has been no volume production of Super 8 cameras in many decades, and meanwhile a reasonably good quality modern camera such as a mirror less compact can be had for only a few hundred dollars. The value of Super 8 for film makers lies in the properties of the film itself, which this doesn't replicate. Also there is a mystique about working with real film for them, which this cartridge can't possibly replace.
Absolutely brilliant!! I'm going to follow this until you get it sorted! YOU'RE A GENIUS!! Cant wait to see how this turns out!!!!
Well thanks! Progress may be a bit on-and-off, but I have another video on its way.
@@jennylist I'm anxiously anticipating it!
I have two super 8 cameras, so this yes super exciting to me, thanks for sharing!! ❤️🧡💛💚💙💜
Any time! Keep watching, I'll proceed further with this project.
The algorithm works in mysterious ways. Fascinating video. Looking forward to seeing the results.
Thanks :)
I hope you saw the rest of the series. I'm not there yet but I am a lot closer

Hi Iain, and thanks! I'll be doing more on the super 8 project in due course, so watch this space.
Great project and great organization to support! Thanks, Jenny.
Thanks for that :)

I've come to a similar conclusion.
Jenny’s list is amazing!!!
Thanks, I guess :)
This is very clever.
Thank you!
Brilliant engineering , bringing life in this film cameras are godly act.
Thanks! It's not finished yet, there's more to come on this project.
Very cool project. Would pay for one of these! Donated btw… thank you for sharing about the org

Only Just came across this, well done. I have quite a few 8s and was wondering how to modelize them so to speak.
Good luck, and thanks.
@@jennylist Hey Jenny, do you have a stl you would possibly share for that case?>
@@TheDarrenS github.com/JennyList/film-cartridge-models Here you go.
Lovely collection and super (8?) interesting build!
Thanks :) I should add, that's only a subset of the collection of Super 8 cameras I've amassed. It's necessary, because the cartridge has to fit every camera I can find.
Old meets new. Ingenious idea 💡
Thanks! there's more to come with this project, so stay tuned!

btw, the time length of the Super-8 cartridge is not 5' ... it's 2.5' when shot at 24FPS and more than 3' if shot at 18FPS ... 🙂
i'm also thinking that extra empty space in the digital cartridge can be used for quite a number of things ... 1stly, sound recording circuitry can be installed there ... or extra battery to run more power-hungry micro computers and sensors and so on ...
The real problem is getting the sensor in the focal plane. It's surprising how much difference as little as a milimetre makes.

The original sensor mounting in this video wouldn't be helped by this, but I am using exactly this technique with the latest lens mount.
I would use the Film Advance Pin and take a single photograph everytime it attempts to pull the film down ?
It's not the easiest thing to sense, sadly. It's tiny. I have wondered about using a Hall effect device though.
What a cool device!
thanks!
If you ever sell it, I will buy for sure. Bravo!
It's early for that, but you'll see the progress as it happens.
Is it probably to buy this prebuild as I do not have the. Time to make one
No, because it's not finished.
I had the same idea, and i just saw your video ! i'm following you :)
Thanks! I'm momentarily diverted into Single 8, but things are happening with this project and I'll be back with it soon.
Cool project.
Thank you!
Amazing!
Thanks!
Do you sell the 3D print design or can you send it if we want to buy it?
I will make the final version freely downloadable as an open source project.
amazing work, girl!
Thank you!!
Haven't you tried smaller sensors that would fit in the film gate?
No. But there aren't any easily available that are both cheap and easily interface to a Pi.
Take the UV filter off too and put one on the lens instead.
The filter on those sensors is glass, and it's almost impossible to remove without damaging the sensor chip, sadly.
@@jennylist I thought I saw some other UA-cam Videos that show removing the IR Filter on some sensors to make them into Infra-Red Cameras?
I've seen it done on cameras where the filter is a plastic film, but this one appears to be the glass. Of course, there are many different camera sensors out there.
That is a good cause.
Thank you :)
Could I commission you for one of these? Thanks
Sadly not, I'm not a manufacturer.
@@jennylist damn, well great video regardless ^-^
