Introduction: Another Slinky Machine

Picture of Another Slinky Machine

If you're tired of operating your slinky by hand, there is a more complicated and costly way of performing the same useless task.

Step 1:

There are several 3d printed parts involved and I have included the Fusion 360 design files as well as the .stl print files.

The servo connector should be printed at 100% fill--everything else is your choice.

Parts needed:

(2) servo motors (I used Hitec HS-311)

(1) Arduino Uno

(4) AA batteries and holder

(3) RGB fast blink led's

(1) slinky

Misc: tape and screws--wood for the base

Step 2:

Picture of

Attach the servo connectors to the servo horns.

Step 3:

Picture of

Using small wire (I use wire wrap wire), push the wire through the base and attach to each led.

Step 4:

Picture of

Insert the lifters through the square holes in the base unit.

Step 5:

Picture of

Fasten the servo holders to the wood stand before securing the printed base with screws.

Step 6:

Picture of

Attach the slinky with duct tape.

Step 7:

Picture of

Wire according to this schematic and use the sketch for the Arduino. Note that numbers in the sketch for servo position will probably have to be changed to accomodate the way you attach your servos (in my setup, 15 for the left servo and 135 for the right servo represents the "down" position).

Step 8:

Power it on and you will have a noisy, blinking automatic Slinky machine.

FYI: This is not quite as useless as it appears--it will probably be decorated and become an automated toy creation for "Santa's Shop" later this year.

Is the slinky attached, or does it just set on by gravity. I am wondering cause I might make something sorta like this if it is okay.

The slinky is attached with tape--I think it will work on a "seesaw type board" as long as the slinky is attached. Good luck with your version!

Thanks! I will try to make it out of knex.

EDIT: I am totally stupid. I somehow forgot that I don't have a slinky. I probably won't make this for awhile, than.
