Stepper Addon for Sergiu’s Cell Spool Winder

The GOAT Cell Spool Winder is so great that I decided to motorize it. I received permission from Mr. @Sergiu_Irimie to publish the files.You don’t have to change anything, drill, or glue your existing spooler. You only need to reprint the receiving axle so the motor fits inside. I split this project into 3 parts (shown in the picture from top to bottom):Electronics disassembledPower UnitI didn’t want any more cables on my table, so I used an 18V DC battery as the power source. You can substitute this any way you like; there are many adapters for different batteries. I used this one, or you can just use a barrel jack. You can also power the Arduino and stepper independently, getting rid of the blue breadboard part shown in the picture (though that requires two cables).<
