            <title>Motorized half automatic pano head</title>
            <link>http://www.thingiverse.com/thing:2570</link>
            <description><![CDATA[<div style="margin: 5px;"><a href="http://www.thingiverse.com/thing:2570"><img src="http://thingiverse-production.s3.amazonaws.com/renders/4e/5d/c8/ed/91/front_view_preview_large.jpg" alt="" class="render" style="width: 240px; height: 180px" /></a><br/></div><div>**<b>Untested project</b> for the MakerBot Giveaway contest. I’ve got no clue about how sturdy MakerBot printed parts are, this means that I don’t know if the parts I designed are thick enough to support the weight of the camera and steppers. I’m maybe plain wrong ! However, parts size have been carefully designed to fit into Makerbot’s build envelope. The only overhangs are holes, therefore the parts should be printable on a MakerBot (At least, I hope !). STL parts have been checked with Netfabb and are manifold EDIT:I reuploaded the STL parts. They are now oriented in build direction**<br />
<br />
This half automatic pano head has been designed to take pictures using a Canon Powershot A560 compact digital camera. The purpose is to shoot panoramas without getting into the risk of forgetting to take THE PICTURE absolutely needed to get a complete panorama (when you don’t have got a wide angle lens, you need to take a lot of pictures!)... The head moves left/right and up/down. Two NEMA 17 sized stepper motors are controlled by an Arduino  (or compatible clone) using two Sparkfun's Easydriver. The shutting mecanism will be controlled by Arduino.<br />
<br />
The Canon Powershot’s normally don’t have remote shutting capabilities. Fortunately, a great open source software package can add a lot of functionalities to these cameras: CHDK. It adds remote shutting by detecting when voltage is applied on camera usb port.<br />
This head has to be mounted on a standard tripod.<br />
Function: When pressing the start/stop button, the camera will take a picture (or more, if CHDK “bracketing in continuous mode” is checked – needed for HDR), then moves upward, takes a picture,… , then moves left,then moves downwards, takes a picture, … ,and it does the same column after column. When the necessary pictures have been taken, the photograph has to press the start/stop button. After, the reset button has to be pressed to put the pano head back in starting position (only horizontal axis needs to be moved).<br />
<br />
Advantages of this design:<br />
-No need to carry a notebook to control this head. <br />
-Simple to use.<br />
<br />
drawbacks of this design:<br />
 - the row/column intervals and time between moves can only be changed by editing the arduino sketch. <br />
- No care taken about “No-parallax point” for now.<br />
