Based on the Adafruit Resistor Helper papercraft resistor calculator

Nope, you can't purchase one, you gotta make it yourself.
Unless you are one of those who can remember the entire color code for 4- and 5-band marked resistors (test later on how many possible combinations there are; I'm still working on wiring up CAT-5 correctly), you need the help of a reference chart or you can use the handy papercraft Adafruit Resistor Helper. Need a cool thing to wear to work or school? What better time to make or give the gift of a tie? Of course, for the geek and technically inclined, a hacked tie would be even better.
You can make a resistor tie from scratch but you can also repurpose old ties too. Do something with those old power ties to make them current.
I am just going to use a tie I found at the dollar store (really $2, it had a cool sparkly techno vibe in the pattern) and make a few quick mods to implant the papercraft resistor helper.
CAUTION: Know how to use pointy and sharp things like scissors. Know how to sew, press and iron safely.
