Panorama picture maker that I once made.
I wanted to make this in a while and only now in Shanghai I got around to finish the project. Inside works an Arduino pro micro and two of those stepper drivers used in all those DIY 3D printer (RAMPS ecosystem). As always in my projects the body of the device is made from layers of 3mm lasercut acrylic, a technique that IMHO beats classic 3D printing in some ways.
