SUMMARY
Nope, you can't get one there, 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.
Seeing that it is Father's Day soon, what better
time to 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.
Step 1 — Adafruit Resistor Helper Tie
Take a look at Adafruit's Resistor Helper guide to make the standalone resistor helper.
Download the PDF of the resistor helper.
This papercraft resistor calculator was designed by Adafruit with
Matthew Borgatti.

Print out one copy for reference.
Print out one more to cut up and assemble the color wheels.
Print one copy out on your iron-on transfer paper. Know how to use your iron-on transfer
paper. The one I used is for application on dark materials. It requires that the image not be
reversed and it must be printed on the surface that will peel away from the backing sheet.
It is applied directly on where you want it to stick.

Step 2
Follow the instructions on the PDF. The color wheels are paired front and back and are
marked in which order they will be assembled into the case.
You can roughly cut out each pair of color wheels and glue the corresponding parts back to
back. Place under a weight like a telephone book to keep them flat while the glue dries.
When dry, trim close to the edge design.
You can run the color wheels through a laminator or just apply clear packaging tape over
them. This will increase the durability and strength of the color wheels.
Laminate both sides of the color wheel. Trim off excess tape.
From the iron-on transfer print, cut out the separate panels for the sides of the resistor
helper. You should have two pieces, the 4-band and 5-band sides.

Step 3
Like genuine Arduinos, be wary of labeling found on your products.
Time to start dissecting the tie. Use a seam ripper tool since that is almost as good as a
scalpel in working with delicate tie material. Okay, we've got real polyester here instead of
silk.
Break the bar tack that holds the back of the tie together near the bottom. Splay the tie out
up to where the tie holder label is. You might need to free up a side of the label too.
Using one of the resistor holder side panels as a size guide, position it on the tie so that
you can see you have access to that much of the tie.
You can place the resistor helper on either side of the tie. The preference is determined by
which hand the wearer will prefer to use to access the thumbwheels.

Step 4
There is a piece of thick fabric inside that is the interfacing or stiffener for the tie. We need
to cut out the portion where the color wheels need to be seen on both sides of the tie.
Transfer the markings where the color wheel windows will be to the interfacing.
Cut out that piece of interfacing.
We need to restore structure to the tie by applying a piece of fusible interfacing to the tie's
outer fabric where the original tie interfacing has been removed. This also reinforces the
tie fabric so we can cut out the windows for the color and number values. Also, the paper
fasteners will be inserted through there.
Cut a piece of fusible interfacing the size of the side panels. Fold in half and mark the fold
so it is easier to see.
Line the interfacing up with the fold in the edge of the tie. I had to trim the front a bit so it
would not intefere with the seam and fabric tie liner at the point.
Apply heat with a clothes iron set a moderate heat to bond the fusible interfacing.
