#FreeLSS
FreeLSS is a laser scanning program for the Raspberry Pi. It allows a Raspberry Pi to function as the core to a complete turn table laser scanning system.
Additionally, the standard Linux buld allows the use of an ordinary webcam and the Arduino-based turntable/laser driver from the FabScan100 Fab Lab project.
###COMPILE
These instructions assume you are running the latest version of Raspbian or Debian/Ubuntu for base Linux maches. Other distros will likely require changes.
First, update the firmware to the latest version and reboot.
$ sudo rpi-update
Install the dependencies that are managed by the package manager:
$ sudo apt-get install libpng-dev libjpeg-dev cmake vlc git-core gcc build-essential unzip sqlite3 libsqlite3-dev libmicrohttpd-dev
If using a standard Linux webcam also install packages for that:
$ sudo apt-get install fswebcam
Download and install wiringPi if using a Pi:
$ cd
$ git clone git://git.drogon.net/wiringPi
$ cd wiringPi
$ ./build
Download and install Raspicam if using a Pi:
$ cd
$ wget http://downloads.sourceforge.net/project/raspicam/raspicam-0.1.1.zip
$ unzip raspicam-0.1.1.zip
$ cd raspicam-0.1.1
$ mkdir build
$ cd build
$ cmake ..
$ make
$ sudo make install
$ sudo ldconfig
Download FreeLSS:
$ cd
$ git clone https://github.com/hairu/freelss
$ cd freelss/src
Now edit Makefile with your favourite editor and set the TARGET variable to either "pi" or "linux" depending on which camera and turntable hardware you wish to use.
Finally, build FreeLSS itself:
$ make
###Running FreeLSS FreeLSS must be ran as root (or another user with access to the hardware pins). The interface for FreeLSS is web based and by default runs on port 8080 (you can change this to 80 in Main.cpp if running as root). When running, access FreeLSS by navigating to http://localhost:8080/ from the Raspberry Pi itself. Or access it from another machine on the network by the Raspberry Pi's IP or hostname. For Example: http://raspberrypi:8080/
The following command starts FreeLSS as root.
$ sudo ./freelss
