Why a new FabScan version:
One of the goals of the new software and hardware design was to keep things simpler and more affordable. The most important improvement was to make the FabScan a platform independent stand-alone device. This is why i decided to use a Raspberry Pi as base and a web interface was made for scanning. This enables the user to use the FabScanPi with nearby every device which has a web browser installed.
Another idea was to make the software more friendly for less skilled programmers. So the software was split up into two parts, a JavaScript based ui and a Python based backend server.
FabScanPi is the ideal project for 3D scanning hobbyists, enthusiasts and also education.

Software
Python was chosen as programming language for the backend, because with the usage of Python there is no need for a complicated compiler toolchain.
The web interface is written in Javascript using WebGL. Backend and Frontend are communicating through a web socket and REST API. This software design enables even beginners to work on the software.

Hardware
FabScan PI2 uses a Raspberry PI2 with the PI camera module as base system. Additionally a 12 LED ring is added make environment lighting control easier. With this combination the scan results can be drastically increased. The new designed FabScanPi HAT for the Raspberry Pi provides place for up to 3 stepper motor drivers, two laser connectors and at least 2 servo connectors. A safety plug on board can be used to turn the laser off when the lid of the scanner is opened.
All electronic parts are mounted in a plywood case.

super cool project , i have been following the fabscan for quiet a while and have built a linear scanner around 8 years back . Is there anyplace i can find sample scan models just to compare quality? great work by far i must say
