Ranjit, hey, thanks for noticing :-) > Happen to see the case of Milkymist one[1], it is a transparent > material and would prefer GTA04 embedded in case like that, with full > view of itsy bitsy circuits and chips, don't know how feasible is it. > [1] http://milkymist.org/mmone.html
That case was designed and manufactured by fantastic Raumfahrtagentur in Berlin http://raumfahrtagentur.org/ roh from Raumfahrtagentur used QCad for design and laser cutting, the original .dxf files are freely licensed and published https://github.com/milkymist/extras-m1/blob/master/cad/protocase_v8_laser.dxf QCad: http://en.wikipedia.org/wiki/Qcad There are many details that still need improvement, mechanical work is labor intensive :-) Screws, spacers, feet, etc. In the later versions we used dichlormethane for gluing the buttons, the entire button design can probably be improved as well. Werner just milled some out of wood http://downloads.qi-hardware.com/people/werner/tmp/m1butwood.jpg We made a wood version of the Milkymist One case earlier, but wood bends over time, if we really wanted to use wood we would need to find out more about that. http://en.qi-hardware.com/w/images/4/42/Milkymist_One_wood_case.jpg The Milkymist logo is engraved into the inside of the top acrylic, it looks nice but as always there is room for improvement there as well. https://github.com/milkymist/extras-m1/blob/master/cad/milkymist_logo_engrave_v1.dxf http://en.qi-hardware.com/w/images/d/d3/Milkymist_engraved_logo_shot.jpg Bottom line: We learnt a lot, made a beautiful and functional acrylic case (often used for architecture models as well, btw). Many details can and will be improved, the process is all open and uses free tools. Kristian Paul used the same files to make his own Milkymist One case in Bogota, Colombia. In the future we may also investigate milling or lasering aluminum, maybe starting with the same .dxf design files we have right now... If anybody has questions about a mechanical design and manufacturing process using free tools, don't hesitate to join the Qi list at http://lists.en.qi-hardware.com/pipermail/discussion or the #qi-hardware IRC channel on Freenode, webchat http://en.qi-hardware.com/webchat Last but not least - Milkymist One sells for 499 USD plus shipping at https://sharism.cc/milkymist About 40 of 80 run3 units have already sold in the last 3 weeks :-) By buying one you support the entire free supply chain, including Raumfahrtagentur in Berlin.
