Introduction: Lego Coil Winder
hello everyone, i am currently working on, though almost finished, building a Lego induction coil winder, which as the name suggests, is a coil winder made from Lego.
this winder is made specifically for making coils to use for coil guns.
Its a basic motor and line feeder setup, though soon i will add a pulse width modulator for both the line feeder and the winding motor, to control the speeds. and i will post all specs, along with a 3D rendered animation of how to put it together, and basic Lego instructions (made with Lego software if at all possible), plus schematics for the speed controllers.
The line feeder when completed will use a flip flop relay setup, and two contacts at the ends of the toothed bar, and each time the line feeder touches them, it will change the state of the relay (on / off ), and move in the opposite direction.
Ill add more photos when this is all done, but for now, here is what Ive done thus far. there is no speed controlling, though it spins at an appreciable rate, and the line feeder needs to be worked by hand (since i don't have a second motor, though one is on its way ), but its all fine.
For obvious reasons the wire needs to be already spooled, which is what Ive done in the picture. i wound up all the wire onto a spool, off of a piece of wood, so that i may use it to properly wind a coil.
soon also i will make a better way to secure things onto the Lego, but since for the moment im winding onto Lego which as the same diameter as the inner diameter of my coil gun copper tube barrel, there's no need.
sorry the photos are a little blurry, its because my room is so dark even with the light on, and my camera enhanced the photo.
-edit- i just added the 12mp photos as the first 4
We have a be nice policy.
