Emission Spectra Scarves
These Emission Spectra Scarves are lovingly machine-knit from black and colored 100% cotton yarn. They measure about 6.5 feet long and 7 inches wide.
Pictured above is Matt Mechtley sporting a custom quasar, and Limor (Ladyada) Fried and Andrew Salomone both wearing Silicon.

This scarf was originally Amanda Wozniak‘s idea.
Download patterns to make your own! Thanks to Bryn Davies for the Spectra Pattern Generator Python script (no longer accessible). You can
generate a pattern based on your knitting gauge at Bryn’s site download the python program and run it yourself:

Now that’s damned clever!
If you don’t mind me asking (and giving away your sekrets.) How do you determine the total number of rows, and how wide each band is? That and the usual knitters questions, yarn gauge, and needle size?
I wonder what the emission spectra of Uranium would look like?! 😀
Oh. This is an utterly brilliant idea. I love it! I want to make one for my mom – who does a ton of spectroscopy.
@Seth, it would look like this: http://chemistry.bd.psu.edu/jircitano/U.gif
@Geoffrey: I take a look at the spectrum image from the chemistry site I linked to in the post, and one pixel row = one knitted row in the scarf. The gauge is quite small since I do it on my knitting machine, but you could probably replicate it on small needles, about a US size 3 or so maybe.
I saw a craftster post about this a while ago – someone made a specta scarf for a science swap. I did a podcast episode on how cool it would be to do a quilt of the spectrum. I was inspired by the scarf I saw on craftster and although my spectrum scarf is just an idea and not a product, I am inspired you are doing this as a business. Your process of using the knitting machine is making a really quality product. Do you plot out on graph paper each row? You say you count all the pixels? wow! Very good job Becky. It’s nice to see cool minds think alike:
make the scarfs, and I’ll buy a couple – winter is still several months off for those of us int he Southern Hemisphere.
How much for molybdenum/zirconium?
Hah! Too much.
I’m sorry. I was busy marveling at the utter coolness of this idea, and wondering if Zn would be appropriate for my husband, and then I scrolled past your model’s name, and fell out of my chair. I went to camp with Limor in Israel, ages ago. We were the only geeks there.
Going to have a look at zinc now, while still scratching my head. Double cool.
Don’t know why you’re apologizing… She runs Adafruit Industries, an electronics kit company. Head on over there if you want to say hi, the link is in the post.
Would you be willing to make a manganese scarf? (e.g. is the line-count excessive?) I’d like to get one if you would make it.
Yep! It would fall into the “crazy” category in the way I have them listed on Makers Market.
That is all kinds of awesome. Hubby just went mad with geek. 😀
