Description
######### Update 1: ######### Updaten Software Files In Mnm_Actioncamslider_Software.Zip Changelog App: 1.1 - Added App Icon - Changed Max Time In [H] From 60 To 24 - Setting Time In [H] Now With Minutes - Angle Now Ranges From -180 To + 180° Changelog Scetch: - More Comments - Changed Steps/Rev To Drv8834 Added Wiring Diagram ######################## This Is My Gopro Compatible Action Cam Slider Project. It'S Main Goal Is To Make An Easy, Cheap Slider For Timelapses. This Slider Can Take Up To ~10^38 Sec For The Distance... Should Be Slow Enough Xd Fastest Speed Is 500 Steps/Sec => 1 Revolution In 4 Sec => 20Mm/Sec (At 26Mm Wheels) ######### Hardware ######### There Are Two Versions: 3D-Printed [Pv]: Just Print All The Parts. 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 For All Versions; 2X M8 Screws (25Mm For Pv, 30-35Mm For Nv) 6-8X M3X10Mm (8 If You Do Not Glue The Topmotor Mount To The Base) 1X M5X15Mm 1X 10Mm Tension Spring Or A Rubber Band 2X 608Zz (Skateboard) Ball Bearing For Nv: 2-X M8 Nuts (Depends On Wanted Hight And Material) 2X 20Mm Spacer (With M3 Thread) Electronics (Linked Parts On Ebay [Affiliated]): 1X Arduino Nano (Or Compatible) Https://Goo.Gl/6Ux23S 1X Hc-05 Bluetooth Module Https://Goo.Gl/X27Cm0 2X 28Byj-48 Stepper Motors Https://Goo.Gl/Tdyjsp 2X Stepper Motor Drivers. Best Would Be To Use Drv8824 Or Drv8834 Https://Goo.Gl/Bni40L Both Can Drive Low Voltage Stepper Motors But They Are Relativly Expancive (~10$). That Way You Could Run Everything From A Power Bank. If You Have Some A4988 Laying Around You Can Also Use These, But Than You Have To Supply >8V And Step It Down To 5V For The Arduino And Bluetooth With This Converter Https://Goo.Gl/Swpdlk For Example. ######### Software ######### (All In Mnm_Actioncamslider_Software.Zip) Arduino: Custem Settings (E.G. Wheel Diameter) Are Set In The Top Of The Scetch Upload The Arduino Scetch To The Arduino Smartphone (App Android Only, Workaround For Ios): The App Was Made Using The Free "Mit App Inventer 2" You Can Just Download The Apk And Install It (Allow Unknown Sources Under Settings>Security) 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. Pair The Hc-05 And Your Smartphone Before Connecting The App To The Slider Or It Will Not Show Up. Ios: You Can Use A Bluetooth Terminal App Like Bluterm To Control The Slider. Just Send The Commands Explaned In The Following Protocol. ######### Protocol ######### The Protocol Is Pretty Basic But Easy To Extend. The Commands Always Have The Pattern: #;#;#;#. The First Digit (At The Moment)Can Be 0 (=Set) Or 1 (=Move) For Now You Can Only Set The Wheel Diameter (Diameter On That It Is Running). Default Is 26Mm To Set 30Mm Wheel Diameter: 0;30;0;0. (Canges Are Not Stored In Eeprom At The Moment!) Moving: 1;Timeforthemove;Distance;Tiltcamangle Example: 1;20;100;30. The Move Will Take 20 Sec, Along 100Mm (Left To Right) And Tilt The Cam 30° You Can Use Negative Values For Way And Tilt To Move Into The Other Direction If You Set Time To 0 It Will Move As Fast As Possible. ######### More Info ######### For More Infos See The Project-Videos Part1: Https://Www.Youtube.Com/Watch?V=Jt-A2Rkljt4 Part2: Https://Youtu.Be/9_Ftoecn1Go Musik Used In Video: Tours - Enthusiast Http://Freemusicarchive.Org/Music/Tours/Enthusiast/Tours_-_Enthusiast
