Super 8 Camera Digitizer -- Episode 505

In a previous episode, Clem has built a proof of concept to convert a Super 8 film camera into a digital camcorder without any modifications to the camera itself. Many of you asked for a Kit or if a digital drop-in Film Cartridge replacement was possible! Finally, Clem has the chance to revisit the project and uses the New Raspberry PI compute Module 4 and the HQ camera module to build a crazy compact cartridge that is a major stepping stone towards a real product! And during the project, he even had to start his own 3D printer Resin brand just to obtain a material that is up to the task for this project!

    Thanks for asking.

    I call it "MAYER MAKES Engineering Resin".

    As seen in the video it is extremely tough and impact resistant.
    In my quick iterations I often use resin prints that I oversize and while trying them out mechanically adjusting them to fit (by milling turning or carving), once they fit I get measurements and adjust the cad model.
    While I could make fits and shapes perfectly with standard Resin , they would not hold up to actual use as mechanical parts or cases. I usually had to make them with PETG on my Filament Printers.
    On this project PETG was quickly ruled out as it was not accurate enough and stable to allow for the tight tolerances and forces involved (resin got cracked by the internal clamping mechanism of my camera)

    So I used my contacts into my old Job as dev at a 3D printing material company to see ,if it was possible to develop a resin that would fit my needs.
    And after some iterations the outcome was better than expected.
    Very impact resistant and tough.
    once printed it is flexible and yellowish.
    After curing in Full UV spectrum (daylight) it is stiffer and gets fully clear transparent (a great bonus for Cases!!)
    Behaves like machining plastic on the lathe and mill.
    I might replace some stuff I previously made in aluminium with resin prints thanks to my Engineering Resin.

    Of course It would not be viable to just make a bit of resin for me, so I basically had to start my own Resin brand and make it accessible to the public, Ordering the raw materials in bigger batches gets the price down to a competitive level and we all can benefit from it.
    Currently a tiny prototyping batch is in use by myself but another possibly improved batch is in the works. Soon I should be able to send out review samples to some experts/influencers.
    I plan on two other varaints for the future :
    very Flexible (for softtouch surfaces and compliant structures)
    High Temperature
    Let's hope I can get this to market

    Good luck getting this to market.  I'd love to have a material that I could print that had mechanical strength.  I'd vote for the High Temp variant if you had to choose which one to work on next.

     

    Then, I'd definitely have to get a resin printer image...
