Wow, the launch of the crowdfunding campaign was a blast! In less than a week ANAVI Fume Extractor was funded and hit the first stretch goal. All backers will get cool stickers with their kits. With your help we expect to hit the second stretch goal really soon!
As you know ANAVI Fume Extractor is entirely open source product certified by the Open Source Hardware Association OSHWA) with UID BG000060. Does it make any sense to create open source with expensive proprietary tools? Of course not!
ANAVI Fume Extractor has been designed with free and open source tools only. All schematics and resources for the hardware are available at GitHub under Creative Commons Attribution-ShareAlike 4.0 International (CC BY-SA 4.0). Btw the firmware is also open source and it is available as and Arduino sketch under GNU General Public License v3.0.
KiCad is a free open source software suite for electronic design automation (EDA). It is written in C++ and works on MS Windows, Mac OS X and GNU/Linux distributions. The majority of KiCad’s source code is available under GNU GPLv3 (or later) and 3rd party code included in KiCad is under GNU AGPLv3 (or later).
KiCad was started in 1992 but it popularity rapidly increased in 2013 when The European Organization for Nuclear Research (CERN) started using and contributing to it. After that numerous companies switched to KiCad. Most notably Olimex, my open source hardware neighbors and friends in Plovdiv, Bulgaria!
OpenSCAD is a free and open source software software for creating 2D or 3D models. It is written in C++ and works on MS Windows, Mac OS X, BSD and GNU/Linux distributions.
OpenSCAD uses its own description language. The graphical user interface is super simple. Basically you write source code on the left side and a 2D/3D model is rendered on the right. The models designed with OpenSCAD can be exported to various formats, including STL for 3D printing or SVG for laser cutting.
ANAVI Fume Extractor includes a 2 layer printed circuit board (PCB) designed with KiCad and acrylic enclosures designed with OpenSCAD which were polished and converted from SVG to PDF using another open source tool InkScape. Other important open source tools used are git and Arduino Software (IDE). All these tools have been used on a GNU/Linux distributions, more precisely Ubuntu 18.04 and 20.04 LTS.
So ANAVI Fume Extractor is not just an entirely open source product, furthermore it has been designed with free and open source tools only!
