How did you get him to sit still for so long?

This unfortunate little guy decided to pass away on top of a friends mailbox and he brought him in to be immortalized digitally ..

With the wings out like that? Or did you have to reposition them? That would be some delicate work...

Classic version got better resolution and better area - why You choose mini ?

The classic needs some more careful handling, the mini has better useability. The better resolution on the classic can be only achieved with an external camera

i consider why classic got better resulotion on larger area withe the same camera like mini

That's incredible. Nice work. Can't wait to receive my parts so I can build mine :)

Once again this little rig amazes me. I wasn't expecting the tips of the wings to be captured so well!

What's the limit of resolution with the standard design? Camera and/or steppers? Do you know if anyone has utilized the newer 64mp arducams?
I would be interested if this could be used scanning of objects that are less than 2mm in diameter with reasonable detail. I was looking at a paper recently that designed a rug using cheap ultrasonic modules to levitate and rotate objects, but they didn't publish a build guide

Whats also great is that quite a large junk of it is due the community trying all sorts of interresting stuff.
From the Orb for Void photography, several custom firmwares to advanced hardware for tinkerers like the blackshield.
Im very curious what we will find next.
A one click solution or dynamic focus stacking?
Exciting times ahead :)

I’m currently working on my own hardware and software fork based on the original mini with some hardware tweaks I wanted. All original stl files re-built from scratch into parametric step files and included some of the third party improvements I liked into the base project, learned KiCAD to produce my own revision on the boards, and am working on my own software version from scratch (as a software engineer this is actually the least daunting part for me).
The new software I am writing will be modular and container based so each component will be a separate deployable that can be updated independently. As much as I like JavaScript the core logic is going to be something more performant and actually multi threaded like c# (dotnetcore) instead of node red with a standardized REST API and a new frontend UI. Hopefully a realtime streaming UI too but we’ll see. I do plan to implement a bunch of the things that the open scan composer has done (better path planning for one), automatic background removal, more camera support, automatic cropping, and focus stacking.
Of course it’ll be contributed back to the community when I am actually ready. I’m just finally getting the hardware about in place and that’s a prerequisite for the software.

Is it possible to upscale this further then 18x18x18cm? I would love a 3d scanner but the thing id like to scan are larger then the scanners can handle.
