Heavily modified Instax SQ6 with a Hasselblad back

Fujifilm Instax Square SQ6 Specifications/Information

I looked up the specs for the SQ6: image size is 62x62mm. Hasselblad format is 6x6cm, and the actual opening on a Hasselblad back is 61.2x61.2mm. A rough estimate suggests modifying the back is feasible. So... let's get to work.

Current progress: 98% – substantially complete.

• Focal plane alignment
• No modifications are made to the Hasselblad camera body.
• The back section can be detached separately.
• Hasselblad native digital back connection method
• Featuring a blade-insertion structure
• The instant instax is ejecting the photo.
• Focusing is normal.
• Shutter is functioning normally.
• Card ejection is normal.

I'll add the details once everything is fully refined; for now, let's just look at the process.

Update

Mass production is being planned; stay tuned.

Release some technical data

Regarding dimensions:

Hasselblad back mount to focal plane distance: 3.3; Hasselblad film cassette dark slide thickness: 1.1; SQ6 mount to focal plane distance: 4.26; SQ6 mount dark slide thickness: 1.21; instax film cassette front and back plastic thickness: 1.5.

Circuitry:

There are two options,

1. Replaced the original circuit board with a custom PCB utilizing the DRV8838 to implement the automatic chip-dispensing function.

Circuit schematic:

The circuit board looks like this:

If you need the PCB files, join the group and ask me for them.

2. Wire a microswitch in parallel to enable automatic card dispensing.

Circuit schematic:

Simply connect the wiring according to the circuit diagram to enable automatic card dispensing.
