For the upcoming school year, her school is providing the teachers with new big screen TVs and iPad tablets. Previously, she used a  mobile phone connected to a scissor-bracket, connected to a desk clamp for a document camera. Her complaint about that setup was that it was pretty wiggly. Now that she has shiny new hardware, she wanted an upgrade to her document camera setup, and she wanted to use the iPad&#8217;s screen mirroring capabilities.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"Design\">Design<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">My approach was to design something budget-friendly and easy to build. PVC pipe and fittings are budget friendly, and the build only required one tool, besides a tape measure: a low-cost ratcheting PVC cutter. I saw other designs that required saws and drills. This design avoids using a saw or drill by utilizing off-the-shelf mounting hardware.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The lengths of the PVC pipe sections were based on fitting a normal, letter-sized sheet of paper under the camera. The height of the 9-inch vertical posts create a working distance that fits the whole sheet of paper within view of an iPad camera.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"Materials\">Materials<\/h2>\n\n\n<div class=\"wp-block-image\">\n<figure class=\"aligncenter size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"768\" height=\"1024\" src=\"http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/2022-08-14-Doc-Cam-crop-768x1024.png\" alt=\"\" class=\"wp-image-586\" srcset=\"http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/2022-08-14-Doc-Cam-crop-768x1024.png 768w, http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/2022-08-14-Doc-Cam-crop-225x300.png 225w, http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/2022-08-14-Doc-Cam-crop.png 800w\" sizes=\"auto, (max-width: 768px) 100vw, 768px\" \/><\/figure>\n<\/div>\n\n\n<p class=\"wp-block-paragraph\">My design is composed of: low-cost 3\/4-inch PVC pipe and fittings, a tablet\/phone tripod mount, <s>an 11-inch <em>Magic Arm<\/em> &#8212; a 2-section articulating bracket<\/s> a short <em>Magic Arm<\/em>, and a <em>Super Clamp<\/em> &#8212; a clamp suited well for mounting photographic equipment to cylindrical objects, such as poles, stands handlebars, and pipes. What&#8217;s magic about the <em>Magic Arm<\/em> is that 1 knob loosens and tightens all joints. Manfrotto is the company behind the original, high-quality, pricey versions of the <em>Magic Arm<\/em> and <em>Super Clamp<\/em>. I am using knock-offs, but the specifications say that they will support a payload of <s>2kg<\/s> 3.5kg, which exceeds the weight of an iPad and the tripod mount. I chose the particular tripod mount because it&#8217;s all metal and accommodates both tablets and phones.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Bill of materials<\/h4>\n\n\n\n<ul

Before doing this step, you might want to tighten the <em>Magic Arm<\/em> so that it isn&#8217;t so floppy. The clamp needs to be around 8 inches from the right vertical post, not centered when using an iPad, because of its camera location.<\/li><li>Clamp the Super Clamp onto the 12-inch PVC cross bar with the opening facing down.<\/li><li>Insert the camera device (tablet or mobile phone).

Place the whole setup so that you are looking at the document in the correct orientation.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Landscape Orientation<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">When using the camera for a document in portrait orientation, I think it&#8217;s helpful to lock the tablet or phone in landscape orientation <em>before <\/em>inserting it into the mount. Place the whole setup so that you are looking at the document in the correct orientation.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Screen mirroring<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">On an iOS device, an iPhone or iPad, you need to use AirPlay screen mirroring. Turn screen mirroring on\/off by using the Control Center (swipe down from upper right corner of screen), tapping on the Screen Mirroring icon, and selecting the target device. Air Play can also be activated within certain apps such as YouTube by tapping the AirPlay icon.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">On an Android device, you need to first grant Microphone permission in Google Play Service app by going to Settings &gt; Apps &gt; Google Play Services &gt; Permissions.  To turn on casting, run the Google Home app, and tap the tile of the target cast device. As in iOS, tapping the casting icon within some apps activates casting.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">Annotation with an Apple Pencil on an iPad<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">To use an Apple Pencil for annotation:<\/p>\n\n\n\n<ul class=\"wp-block-list\"><li>Take a photo of the object of interest<\/li><li>Tap on the photo thumbnail in the camera app<\/li><li>Tap on &#8220;Edit&#8221;<\/li><li>Tap on the Markup icon<\/li><li>Select a color and tool<\/li><li>Start annotating<\/li><\/ul>\n\n\n\n<h4 class=\"wp-block-heading\">When not in use<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">With the selected tripod mount, the screw at the top of the mount allows you to easily loosen the mount enough to slide the tablet out when not in use, which you will probably want to do. Loosening the <em>Magic Arm<\/em> knob allows the tripod mount to hang vertically instead of protruding horizontally when not it use.<\/p>\n\n\n\n<div class=\"wp-block-group\"><div class=\"wp-block-group__inner-container is-layout-flow wp-block-group-is-layout-flow\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:100%\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:100%\">\n<figure class=\"wp-block-gallery has-nested-images columns-default is-cropped wp-block-gallery-2 is-layout-flex wp-block-gallery-is-layout-flex\">\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"800\" height=\"1067\" data-id=\"572\" src=\"http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/IMG_7293.png\" alt=\"\" class=\"wp-image-572\" srcset=\"http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/IMG_7293.png 800w, http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/IMG_7293-225x300.png 225w, http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/IMG_7293-768x1024.png 768w\" sizes=\"auto, (max-width: 800px) 100vw, 800px\" \/><figcaption>document in portrait orientation<\/figcaption><\/figure>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"768\" data-id=\"579\" src=\"http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/IMG_7290-2-1024x768.png\" alt=\"\" class=\"wp-image-579\" srcset=\"http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/IMG_7290-2-1024x768.png 1024w, http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/IMG_7290-2-300x225.png 300w, http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/IMG_7290-2-768x576.png 768w, http:\/\/lucina.mastroid.com\/wordpress\/wp-content\/uploads\/2022\/08\/IMG_7290-2.png 1067w\" sizes=\"auto, (max-width: 1024px) 100vw, 1024px\" \/><figcaption>document in landscape <br>orientation<\/figcaption><\/figure>\n<\/figure>\n<\/div>\n<\/div>\n<\/div>\n<\/div>\n<\/div><\/div>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"Alternate\">Alternate Hardware<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The 11-inch <em>Magic Arm<\/em> could be replaced with something not as flexible in regards to adjustment potential. This isn&#8217;t a big deal because any possible target device&#8217;s camera has zoom capability.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The ball head that came with the tripod mount and an additional purchase of a male-male 1\/4&#8243;-20 adapter <a href=\"https:\/\/www.amazon.com\/gp\/product\/B09NR4W846\/ref=ox_sc_saved_title_4?smid=A3A0UFDELGC6AT&amp;psc=1\" target=\"_blank\" rel=\"noreferrer noopener\">https:\/\/www.amazon.com\/gp\/product\/B09NR4W846<\/a> could possibly replace the <em>Magic Arm<\/em> in the design.
