Introduction: Lightsaber Knitting Needles

Picture of Lightsaber Knitting Needles

An Epic Battle With Every Stitch...

I will not embarrass you with my poor knitting but maybe someone out there can "give me a hand! Right?"

I will however show a cast on at night in a darkened room with the lights off!

I made a second set at 8 inches length for the pocket size contest!

And a third with smaller diameter rods for tighter stitches!!!!!

these have 1000 uses... can you guess them all?

Step 1: Gather the Supplies

Picture of Gather the Supplies

3/8 Lucite rod
several key-chain LED flashlights(princess auto 2.99)
Green LED
2 X 10 Ohm resistor
heat shrink tubing
120 Sand paper
Scotch-bright pad
resistor (10 Ohm)

Soldering iron
Bastard file

Step 2: The Light Is Wrong!!!

Picture of The Light Is Wrong!!!

This flashlight uses a white LED light and has no resistor!

This flashlight has a small circuit board with LED  on the non-trace side. De-Solder the white light!

Change  the colour to super bright Red/Green as shown and add the resistor as shown. Good/Evil will have to Wait!!!!

Before assembly cut off the top of the new LED with a Dermel cut off disk as shown, and leave it cloudy.

You will need to add a stable base and current limiting resistor, mount the resistor as shown.

To support the resistor add heat shrink as shown. in the trace side of the small circuit board.

The heat shrink will add stability and support to the circuit.

Step 3: Make the Light Pipe!

Picture of Make the Light Pipe!

Cut an appropriate diameter Lucite rod to length as below.

The Lucite rod needs to first be scored and shaped with a file, then with sand paper then with scotch-brite pad to eliminate snags.

A standard hack saw can be used to cut the rod to length but this creates an uneven edge that will take a while to file flat.

The rod can be scored with a file or knife, but I find that a tubing cutter makes a clean break point.

The rod is then secured in a drill  for finishing.

With the rod turning at a slower speed ( to prevent friction burning your hand or the rod), pull it against the file to remove unwanted rod bits...

continue shaping until you have the desired look. In this case a needle point.

You will have to reposition the rod in the drill chuck and work on the base. it will need to be shaped to fit into the head of the flashlight and flat against the cut LED. This is determined by the repositioning of the updated LED circuit board into the flashlight head.

Make two the same with different lighting colour, since I'm old, red and green work nicely for me!



As with any saber, you will have to personalize it for you liking. I used copper an aluminum foil tape for minimalist decoration.

Have fun and may the knitting be with you!

I found the flashlights at amazon in colored packs of 5. they say columbia on the side, but that is easily dealt with via the foil tape.

Really cool. Cant you copywrite the idea or something so they don't get ripped off?

indywave (author)2014-01-18

If some one made me one how much would you sell it for to me?

Random_Canadian (author)indywave2014-02-23

I am currently way too busy to get around to making more of these, Sorry.

As with my lighted Newton's Cradle, I suspect that think geek will have someone rip this one off shortly as well.

indywave (author)2014-01-18

By the way awesome

Ingulit (author)2013-12-16

I love these, and I'm hoping to make some very soon! Any chance you could post the dimensions of the mini flashlight? I don't have a Princess Auto store anywhere nearby, and like an earlier poster said they aren't on the Princess Auto website (and the direct-from-China link is broken). I know it needs to accept a 3/8 Lucite rod, but I'm not overly sure how much larger the light is supposed to be judging from the pictures.

I love this! It's cute and stylish and I cannot wait to make a few pairs of these... These are amazing and I think they will be helpful for pre-sleep knitting. (Knitting makes me sleepy but lamps do not.)

BrittLiv (author)2013-07-21

Wow, now I really need to start knitting again! I made a sock once, but lost interest and never finished the second one...

clcok511 (author)2013-07-11

LOL MAY THE KNITTING BE WITH YOU TOO!!!! :D and is it okay if I make these and then sell them (because of all the copywrite stuff...)

bpeek (author)2013-06-10

where can i find the keychain led flashlights needed for this project? i checked princess and couldnt find the peticular model displayed

Random_Canadian (author)bpeek2013-06-22

You can order direct from China... one example from

Random_Canadian (author)bpeek2013-06-10

I usually go in and get them from a big bin by the checkout. I will try to source an alternate for you.

Luke, use the force!!!

lbrewer42 (author)2013-06-09

Amazing... and i thought my light saber chopsticks ( were great!

JenniferLeighLu (author)2013-06-09

That's so cool! I'm making that!

panakanic (author)2013-06-09

Oooooooooo! I don't knit, just crochet, but there are clear, plastic (lucite? not sure) crochet hooks in many colors in the stores. Wonder if this would work with them??? I want! Coolest idea for fiber artists, in a long time!

Kurisutsure (author)2013-06-07

Whoa... I think I should take up knitting...

caarntedd (author)2013-06-07

Very cool.

To get the light travelling the length of the rod simply take a lighter or small torch to the end of both the LED and rod. Seperatly, and not for too long. This will make the plastic crystal clear and allow for a better edge lit effect.

Now, time for me to share your instructable with a ton of people who would love these.

The cyano glue makes the cut ends optically pure when the plastic bits are joined, as long as there are not big tool marks... I found this out on a previous project. saves quite a bit of time by not having to polish the ends.

Thanks and I already have requests... who knew?

Huh, that makes sense with the glue. For plastic suppliers have you tried Sabic Polymers in Calgary? They are way better for price assuming you don't just need a tiny piece, in which case IPP is just fine.

Grumpycat is a fine addition

Thank tubbypaws for the pattern. I have taken the design and have been costuming the cat for a while now...

I even started a facebook page as mentioned... lots of fun, long story but now I have another hobby!

Coolest knitting needles ever!

Tarun Upadhyaya (author)2013-06-06

I always wanted to have these when I was a kid. Now I think I can make one :D. Thank you for sharing your awesomeness :)

canida (author)2013-06-06

These are so awesome! Want want want.
*adds to to-make list*

iminazoo (author)2013-06-06

Where would I find lucite rods?

Random_Canadian (author)iminazoo2013-06-06

They are available through specialty plastic suppliers or sign making shops. Local to Calgary the place I go, and would not recommend, is Industrial Plastics.

Dominic Bender (author)2013-06-06

Cool idea! Looks very stylish, thanks for sharing. The way I knit I'd probably be afraid I'd break them, though...

They are quite durable. However if you break standard needles then all bets are off! ;-)

jessyratfink (author)2013-06-06

Eeeeee, so neat! I know several people that need some of these. :D
