an enclosure for your project"},"content":{"rendered":"<p><strong>Introduction &#8211; a brief history of project enclosures.<\/strong><\/p>\n<p>Project enclosures not only protect electronics from the elements\u00a0and provide a way to handle, they also\u00a0give it personality. \u00a0Various materials can be used to enclose electronics, such as wood, plastic, glass, or\u00a0cardboard. \u00a0The only limitation\u00a0is the process to create the enclosure. \u00a0Traditional plastic enclosures are available online and at most electronics parts stores. \u00a0These cases are relatively inexpensive. \u00a0Albeit they are easy to get, they have some drawbacks. \u00a0Rarely do they fit your project perfectly.<\/p>\n<p>Machining custom cases is a tasking process. \u00a03D printing\u00a0can simplify\u00a0this process\u00a0by using\u00a0CAD files. \u00a0These files can be created, modified, and shared\u00a0online. \u00a0This\u00a0enhances the entire build phase.<\/p>\n<p>Having a 3D printer may not be an option for some, so printing services are\u00a0key. \u00a0<a href=\"http:\/\/www.shapeways.com\/tutorials\/sketchup_3d_printing_export_to_stl_tutorial\" target=\"_blank\">Shapeways<\/a> provides a method for creating enclosure models with CAD programs like\u00a0<a href=\"http:\/\/www.sketchup.com\/\" target=\"_blank\">Sketchup<\/a> and <a href=\"http:\/\/meshlab.sourceforge.net\/\" target=\"_blank\">Meshlab<\/a>. \u00a0 \u00a0Websites like <a href=\"http:\/\/www.thingiverse.com\/\" target=\"_blank\">Thingiverse<\/a> can be used as a model source. \u00a0Using the CAD program, the enclosure can be designed to meet the needs of the project.<\/p>\n<p>However, not\u00a0all enclosures fit this design. \u00a0Enclosures used in research and development are problematic. \u00a0Once the project is done, the used cases end up as waste. \u00a0This makes the\u00a0costs of manufacturing an enclosure wasteful.<\/p>\n<p>Recently I came across an item that was presented\u00a0at a Google IO event. \u00a0These VR headsets use an\u00a0Android smart phone as the display screen. \u00a0What&#8217;s clever is the headset is almost entirely made of cardboard.<br \/>\n<iframe loading=\"lazy\"

much better suited for R&amp;D than traditional cases. \u00a0<a href=\"http:\/\/blog.mcmelectronics.com\/post\/Build-Your-Own-Raspberry-Pi-Case-from-Cardboard-or-Cardstock#.VC6v7vldXTo\" target=\"_blank\">MCM Electronics<\/a> provides a way for folks to do this themselves. \u00a0Having the option to bulk order these seems more practical than creating them one by one, which could be\u00a0spent developing. \u00a0<a href=\"http:\/\/www.guidedproducts.com\/\" target=\"_blank\">Guided<\/a>\u00a0is\u00a0a manufacturer of custom cardboard packaging. \u00a0It&#8217;s a perfect fit. \u00a0When the project life cycle is complete, the enclosure is recycled.<\/p>\n<p><strong>Purpose &#8211; projects that have different enclosure requirements<\/strong><\/p>\n<p>I&#8217;ll go over\u00a0these options with\u00a0some projects that have a need for enclosures. \u00a0The first is a compartment for a helmet camera, the next is a lobby video kiosk, and the last is lab equipment for up coming course work.<\/p>\n<ol>\n<li>The compartment is needed to mount\u00a0a mobuis camera\u00a0to the helmet. \u00a0I have a mount\u00a0design to base off of,\u00a0so\u00a0I won&#8217;t\u00a0need to design it from scratch. \u00a0It will need to be able to handle being outside and exposure to constant sunlight, heat, cold,\u00a0or\u00a0rain.<\/li>\n<li>The lobby video kiosk won&#8217;t be as difficult. \u00a0It will house a raspberry pi board and will be mounted behind a monitor screen. \u00a0The unit will be inside. \u00a0The only concern I&#8217;ll have is heat and dust effecting\u00a0the electronics.<\/li>\n<li>The lab equipment will be handled and moved around. \u00a0The only issue is keeping it enclosed to make work easier. \u00a0The setup may change so having an enclosure with low costs will be key. \u00a0I would also like to have the ability to fabricate quickly.<\/li>\n<\/ol>\n<p>These scenarios should cover most enclosure options and will give us a comparison why one is more suited than the other. \u00a0 Let&#8217;s begin.<\/p>\n<p><strong>Details &#8211; making an enclosure that best fits the project<\/strong><\/p>\n<p>We&#8217;ll be using 3 examples that have unique design requirements, which are the camera enclosure, video kiosk, and lab gear. \u00a0I&#8217;ll start with the more demanding camera enclosure\u00a0project and have the others follow.<\/p>\n<p>The camera enclosure\u00a0is going to be a 3D printed case. \u00a0The deciding\u00a0factor was that the enclosure will be out in the elements. \u00a0That disqualifies cardboard. \u00a0Another factor is that\u00a0no standard case is on the market, due to the fact this is a custom built project. \u00a0This makes 3D printing the best option. \u00a0Since no standard case exists, this means finding a CAD model online might work. \u00a0However, I&#8217;ll need to draw the model with a CAD program. \u00a0we&#8217;ll be using <a href=\"http:\/\/www.sketchup.com\/\">Google Sketchup<\/a>.<\/p>\n<p>First thing I did was\u00a0create a profile on <a href=\"http:\/\/www.thingiverse.com\/cloudacm\/about\">Thingiverse<\/a>. \u00a0Since this is going to be a source of models, I figured it is only right for me to share what I create back. \u00a0Now that the formalities\u00a0are out of the way, we&#8217;re ready to find something to use as a starting point.<\/p>\n<p>The sensor helmet I wrote about in past posts has been a truly difficult project. \u00a0I have been faced with one complex challenge after the next. \u00a0One of those challenges is housing camera electronics inside the helmet. \u00a0I succeeded in implanting a 720p near IR 808-16 camera and a 1080p Mobius camera. \u00a0However, the Mobius camera operated sporadically. \u00a0This can be seen\u00a0here in\u00a0footage that was the last time it operated.<br \/>\n<iframe loading=\"lazy\" src=\"\/\/www.youtube.com\/embed\/y1bY0ebaBvQ\" width=\"420\" height=\"315\" frameborder=\"0\" allowfullscreen=\"allowfullscreen\"><\/iframe><\/p>\n<p>This was a first for me. \u00a0I have no previous field experience with the Mobius\u00a0camera, but plenty with the 720p 808-16 camera. \u00a0I concluded that I&#8217;ll need to do the same with the Mobius to\u00a0get a better understanding of what it can do and why.<\/p>\n<p>Searches on Thingiverse for Mobius turned up more results than I expected. \u00a0There was a <a href=\"http:\/\/www.thingiverse.com\/thing:340676\" target=\"_blank\">base housing<\/a> already drawn and another of the <a href=\"http:\/\/www.thingiverse.com\/thing:431362\" target=\"_blank\">camera<\/a> itself. \u00a0I had something to work with now. \u00a0Using Sketchup with the models from Thingiverse required some work, since the data files are in a STL format. \u00a0This was solved by installing the STL plugin for Sketchup. \u00a0I found the steps to do this on <a href=\"https:\/\/www.shapeways.com\/tutorials\/sketchup_3d_printing_export_to_stl_tutorial\" target=\"_blank\">Shapeways<\/a> website.<\/p>\n<p>Now that I had the models, I began to make the changes needed. \u00a0It didn&#8217;t take me long. \u00a0The finished model can be <a href=\"http:\/\/www.thingiverse.com\/thing:501958\" target=\"_blank\">found here<\/a> if you&#8217;re interested in downloading and printing it. \u00a0It has been downloaded over 30 times since posting it last week.<\/p>\n<p>With the model done, I submitted it to Shapeways to print. \u00a0To do this I created my\u00a0account. \u00a0Next, I uploaded the file and selected some build options. \u00a0The site stepped me through this seamlessly. \u00a0The process was much simpler than emailing a rep and waiting to for a response. \u00a0It took all of 10 minutes to have my order done.<\/p>\n<p>Since it was so easy to do make the enclosure for the camera, I did a search for the raspberry pi enclosure. \u00a0Sure enough, I found one, downloaded it, and submitted it. \u00a0The cost of printing it was double of one already molded, but low enough to make that choice worth it. \u00a0That takes care of that, now for my final enclosure.<\/p>\n<p>I did a search for cardboard patterns for boxes and found <a href=\"http:\/\/rehabdesign.web.unc.edu\/files\/2011\/05\/box-template.jpg\" target=\"_blank\">this layout<\/a> to use. \u00a0I used cardboard from one of my helmet boxes and cut away. \u00a0The bends in the cardboard are tricky, so to solve this I used a pizza cutter to seam the joints. \u00a0This worked well and after 30 minutes, I had a project box for my Arduino and Ethernet Shield. \u00a0That was easy.<\/p>\n<p><a

from here<\/strong><\/p>\n<p>The business of enclosures seems like an\u00a0obvious part in electronics, but based on my past experience it gets overlooked. \u00a0The ratio of information about enclosures versus the electronics they hold are extremely uneven. \u00a0For folks entering into the field, this presents a challenge.<\/p>\n<p>The traditional view of enclosures has come to a crossroads, with the vast options available in 3D printing and recycled materials. \u00a0The hobby builder no longer has to be stuck with the hobby builder look. \u00a0This opens up a whole new realm of\u00a0possibilities, by letting\u00a0the general public see the work that merits attention. \u00a0Having quick turnaround will let builders finish an idea, instead of it\u00a0stalling and loosing momentum.<\/p>\n<p>This high tech watch is <a href=\"https:\/\/www.shapeways.com\/blog\/archives\/18302-time-it-watch-how-3d-printing-can-drive-innovation-in-wearable-tech.html\" target=\"_blank\">an example<\/a> of how and idea unheard of a 10 years ago, is a reality today. \u00a0Don&#8217;t sit on your ideas, make them!<\/p>\n<p><strong>Summary &#8211; how it all fits inside<\/strong><\/p>\n<p>The three examples I presented here are just a small representation of what is available to system designers and builders. \u00a0The task of building a custom case is simplified with tools like Sketchup, Thingiverse, Shapeways, and most importantly, the designers imagination.<\/p>\n<p>Finding the right fit\u00a0depends on how the project will be used. \u00a0It also depends on the experience of how a project will work in its intended environment. \u00a0There are no shortcuts to this knowledge. \u00a0At least with enclosure choices, the time for R&amp;D can be
