this one minute video shows how the Digital Super8 app works with the cartridge that’s in the Super8 camera.

All electronics inside the Digital Super 8 Cartridge
We’ve got a working prototype of the Digital Super 8 Cartridge that runs with the Raspberry Pi 3 in an external module with touch screen. Benefits of that solution is the high level of control of operating the Digital Super 8 Cartridge and its settings through the touch screen. Plus the additional real-time monitoring of what is being filmed (in B&W) is a plus.
However the drawback is that the ‘filmtype viewing pane’ of the super 8 camera has to be knocked out of your camera in order to enable the USB connection from the cartridge to the external module.
Some people have suggested to us to try and fit all electronics into the cartridge. Clearly we had to find a smaller Single Board Computer than the Raspberry Pi. Ports and test with the NextThing Co. C.H.I.P. SBC failed as this single core ARM SBC is simply not powerful enough. Now our hopes are on the Orange Pi Zero, which sports a quad-core ARMv7 SOC in a tiny form factor. We have ported the software and the OPI Zero performs reasonably well. Great results for VGA and QHD resolutions. But we need to find optimisations in the code and push for the 720p to runs without dropping frames as well. Whether this will be at all possible we don’t know yet.
Benefits of this solution is that the Digital Super 8 Cartridge can simply be dropped into your camera and you don’t have to work with external module or screen. However the cartridge will have to provide a few buttons and LEDs for powering on/off and controlling settings. Alternatively we are looking at using VNC to provide connection via WiFi to your smartphone where you can then see the desktop of the Digital Super 8 cartridge and control its settings.
We are now waiting for the appropriate Lithium Polymer battery and boost/charge circuit and first need to get all the electronics really to fit within the cartridge. More to follow.
