Electronic Turntable With Perfectly Over Engineered Design
Introduction: Electronic Turntable With Perfectly Over Engineered Design
Hello everyone... Today I'm back with another very exiting project... I do make stuffs.... And i have a channel on Youtube ... So it's quite necessary for me to have few good video and picture shots for my videos... Especially those rotating shots...
Untill now I had one small rotating device... That I made 2 years ago by salvaging parts from many items.... But that one.. Firstly not working properly anymore... And the major problem was... I needed a better alternative..... So I decided to make this new rotating platform for my upcoming projects....
I know that this project is way overkill in some areas... And is not designed properly... But... It's my first time designing a product in 3d and then manufacturing everything... Also.. It's absolute first time with Arduino and Servo motors.....
I learned basic arduino coding and done this project... I also know that my codes do seems wired... I will update my codes when I will get better alternatives....
Untill then... The project is more than enough for my needs...
All the project files and the other descriptions about the used parts will be available down soon...
After printing everything... I noticed some problems with tolerances... So I need to adjust the 3d CAD files also.... So pls be patient with me...
So without further a do.... Let's get started with the project....
Step 1: Deciding the Basic Need of This Project
The basic need of this project is not building a war robot or a space rocket... So let's keep this simple... From my experience with my last Turntable... And the references from the internet...I learned that this Turntable should turn...in both direction... And a controllable speed will be better..
Nothing fancy is needed for this build...
So I proceed with these in mind.... Firstly I thought to use a normal dc motor.... Which I will attach with gears to the system... 116
And will use a so called pwm controller.... Or a voltage regulator for controlling the speed.... But then I came across with the fact that any dc motor would have a huge RPM to work with.. And in this scenario... That will be extra pain (though the Servo also gave me nothing but more pain... 😑)
So I Firstly ordered a MG995 servo motor... Which came few days later... And upon good inspection... I found that the Servo was broken already.... The gears weren't made of metal... And they have already worgn out..... So I returned them... And ordered MG996R this time.... But when it arrived... This servo was a 360 one..... For my application it was OK... But this also had no metal gears inside...
Then as for the controlling the system.... I Firstly tried to use 555 timer Ic to creat a pwm signal..with variable output, to control the Servo... But as for my own surprise.. That doesn't worked either..... So luckily I had a arduino mini in my collection for an another project.. And i tried that.... Which worked with no surprise (I wasn't wanted to use an arduino for this build... But.....)
Then I tinkered with the code... And finally came up with a horrible but working code...
In the mean time.. I printed the parts with my ender 3..in black and white pla filaments...
Step 2: Things We Gonna Need...
For this project... We will need the following items...
* 3d printer
* PLA filament
* Computer
* Fusion 360 (if you want to make your own model) Or any other CAD software
* 3d printing slicer (Cura/ Prusa)
* Arduino mini/nano (if you are using Arduino Namo.. Then you will also need a programming breakout board)
* MG995/Mg996r servo motor
* Buck converter
* 12 volt barrel connector(female)
* 12 volt 2 amp power supply adaptor (1 amp will be workable)
* 2 dpdt 6 pin Switches + 2 momentary push buttons
* 3 Small 3mm LEDs
* Resistors 1k * 3
* Heatshrink tube
* 47k potentiometer ( I had a dual gang one... So I used that because that have a metal Shaft... A normal plastic one will also work)
* Wires
* Soldering items
* Drill machine
* Other random tools
** If you want to use my files..then pls give me some time.. I need to Finalize the files...
Here are the files..If you want to have a look...
Step 3: Preparation of the CAD Model
For this project, I used the version of the personal license of the famous CAD software - Fusion 360... 485
