From Mobile March 2014-Learn how Kristina added electronics to items she can wear. She’ll cover some of the issues I ran into that are specific to building wearable technology and how I solved them.

Conductive thread
Quality is sketchy, buy from a good source!
Sewn in components
Either modified normal components or special ones
Special Arduino
SparkFun has the Lilypad line
Adafruit has the FLORA line

Soft Circuits
Challenge becomes how to add on non e-textile components to clothing
Get a wider variety of components to choose from
Removable == washable
EL Wire Skirt
Do not think of your battery pack last!
They’re heavy, cumbersome, and necessary!
They might make dancing hard! The horror!!
Lesson Learned
LED Array v1
Lessons Learned?
Don’t procrastinate!
Programming for the Arduino is harder than what I’m used to - start early
PROGMEM is your friend
LEDs do not work like they do in your imagination!
LED Array v2 & v3
Goals
As flexible and durable as possible
Use less pins - more pins for other things
Easy to program
Cheaper
Step 1Step 2
Step 3
Step 4
Step 5
Programming
LED is individually addressable
Program translates (x,y) to an address
Color - reference with one number between 1-384 instead of RGB

Scroll and alternate image
Tetris!
Joystick breakout board from Adafruit
Integrated with a flexible wire into the sash
Joystick sticks out of fabric (but this actually doesn’t work so well)
Sewing
Circle Skirts!Measure your waist
Math yourself up a radius
Draw a donut in the fabric
Cut out the donut
Add elastic on one side
Hem the other
Voila!
These pictures and a full tutorial are from http://whatthecraft.com/circle-skirt-tutorial-new-and-improved/
Lessons LearnedFind a good, simple base project
Something easy
Something that can be replicated
Something that can be modified easily
Don’t forget power! (remember that one?)
Removable components are a lot easier
Terrycloth diffuses LED light!
Bottom two pictures are from the Vega Edge Kickstarter: https://www.kickstarter.com/projects/868814363/vega-edge
To Sum Up…Have the base be something easy or make the full thing removable
Hold off building something permanent as long as possible
Don’t forget the battery packs or other bulky parts of your construction
Don’t procrastinate
PROGMEM for putting stuff in storage memory
Terrycloth to diffuse light
