<h6>### Update 1:</h6> <p>Updaten Software files in MnM_ActionCamSlider_Software.zip</p> <p>Changelog App:<br/> 1.1</p> <ul> <li>Added App Icon</li> <li>changed max time in [h] from 60 to 24</li> <li>setting time in [h] now with minutes</li> <li><p>Angle now ranges from -180 to + 180° Changelog Scetch:</p> </li> <li><p>More Comments</p> </li> <li><p>Changed Steps/rev to DRV8834 Added Wiring Diagram</p> <p>########################</p> <p>This is my GoPro compatible Action Cam Slider Project.<br/> It's main goal is to make an easy, cheap slider for timelapses.<br/> This slider can take up to ~10^38 sec for the distance... should be slow enough xD<br/> Fastest Speed is 500 Steps/Sec =&gt; 1 Revolution in 4 Sec =&gt; 20mm/sec (at 26mm wheels)</p> <p>######### HARDWARE #########</p> <p>There are two Versions:</p> <p>3D-Printed [PV]: Just print all the parts.<br/> Non-Printed [NV]: Print the ActionCamSlider_Plans.pdf in 100% scale, glue it to a sheat of your favourite material and cut along the Lines</p> <p>For all Versions;<br/> 2x M8 Screws (25mm for PV, 30-35mm for NV)<br/> 6-8x M3x10mm (8 if you do not glue the TopMotor Mount to the Base)<br/> 1x M5x15mm<br/> 1x 10mm tension spring or a rubber band<br/> 2x 608zz (Skateboard) Ball Bearing</p> <p>For NV:<br/> 2-X M8 Nuts (depends on wanted hight and material)<br/> 2x 20mm Spacer (with M3 Thread)</p> <p>Electronics (Linked parts on eBay [affiliated]):<br/> 1x Arduino Nano (or compatible)<br/> <a href="https://goo.gl/6Ux23S">https://goo.gl/6Ux23S</a><br/> 1x HC-05 Bluetooth Module<br/> <a href="https://goo.gl/X27cM0">https://goo.gl/X27cM0</a><br/> 2x 28BYJ-48 Stepper Motors<br/> <a href="https://goo.gl/TDYjsP">https://goo.gl/TDYjsP</a><br/> 2x Stepper motor drivers. Best would be to use DRV8824 or DRV8834 <a href="https://goo.gl/Bni40L">https://goo.gl/Bni40L</a><br/> Both can drive low voltage Stepper motors but they are relativly expancive (~10$).<br/> That way you could run everything from a power bank.<br/> If you have some A4988 laying around you can also use these, but than you have to supply &gt;8V and step it down to 5V for the arduino and Bluetooth with this converter <a href="https://goo.gl/sWpdlK">https://goo.gl/sWpdlK</a> for example.</p> <p>######### SOFTWARE #########<br/> (all in MnM_ActionCamSlider_Software.zip)</p> <p>Arduino:<br/> Custem settings (e.g. Wheel Diameter) are set in the Top of the Scetch<br/> Upload the Arduino Scetch to the Arduino</p> <p>Smartphone (App Android only, workaround for iOS):<br/> The App was made using the free "MIT App Inventer 2"<br/> You can just download the APK and install it (allow Unknown sources under Settings&gt;Security)<br/> If you want to have a look at the Code or don't trust me (;P) create an App Inventor account and import the .aia-file.<br/> Pair the HC-05 and your Smartphone before connecting the App to the slider or it will not show up.</p> <p>iOS:<br/> You can use a Bluetooth Terminal app like BluTerm to control the Slider.<br/> Just send the commands explaned in the following protocol.</p> <p>######### PROTOCOL #########<br/> The protocol is pretty basic but easy to extend. The commands ALWAYS have the pattern: #;#;#;#.<br/> The first digit (at the moment)can be 0 (=Set) or 1 (=Move)<br/> For now you can only set the wheel diameter (diameter on that it is running). Default is 26mm</p> <p>To set 30mm wheel diameter: 0;30;0;0. (Canges are NOT stored in EEPROM at the moment!)</p> <p>Moving: 1;TimeForTheMove;Distance;TiltCamAngle<br/> Example: 1;20;100;30. The move will take 20 sec, along 100mm (left to right) and tilt the cam 30°<br/> You can use negative Values for Way and Tilt to move into the other direction<br/> If you set Time to 0 it will move as fast as possible.</p> <p>######### MORE INFO #########<br/> For more infos see the Project-Videos<br/> Part1: <a href="https://www.youtube.com/watch?v=jT-A2rkLJT4">https://www.youtube.com/watch?v=jT-A2rkLJT4</a><br/> Part2: <a href="https://youtu.be/9_ftOecn1go">https://youtu.be/9\_ftOecn1go</a></p> <p>Musik used in Video:<br/> Tours - Enthusiast <a href="http://freemusicarchive.org/music/Tours/Enthusiast/Tours_-_Enthusiast">http://freemusicarchive.org/music/Tours/Enthusiast/Tours\_-\_Enthusiast</a></p> </li> </ul> Category: Camera
