EL Wire Hat: Sequenced and Sound Activated with Remote Control - powered by Arduino and Sparkfun

Featured
Welcome to the Instructable guide of my EL Wire hat with some fun features.

The concept is an EL Wired hat with 8 sequenced EL wires controlled by a wired remote. Multiple speed controllable sequence modes are pre-programmed into an Arduino UNO, including a sound activation feature.

Features:
7 sequence modes (speed controlled)
1 sound activated mode (sensitivity controlled)
1 sequence mode that goes through all 7 previously mentioned sequences.

The brain behind my baby is an Arduino Uno Rev. 3 with a Spartkfun EL Escudo Dos shield.

This psychedelic fashion accessory was built for a festival, so it needed to be quite tough. Also it was built in a bit of a hurry, so steps were not documented during time of build. With that in mind, I will do my best to guide you through what I went through in as much detail as possible.

Step 1: Materials and Tools

A Hat - whatever style suits you and your EL Wire configuration.  We will be concealing our wires on the inside, so keep in mind that we will need to make holes in the hat. I would avoid using your grandfathers trilby :)

I used this guide to make a light suit. Thank you so much for this great information.

Dovadil, you did an incredible job of detailing your instructions. I built this and it was the first electronic build I have done. It worked on the first go! The only thing I changed was I used CAT 5 connectors from the brain to the hat so I can unplug it from there. My next job is to use the brain on another EL wire outfit and I can just plug that into the CAT5 . Cudos to you. i'll work on getting video and pictures up.

Wow tanders0104 - You have no idea how much pleasure it gives me, and what a complement it is, to know that someone else has built and benefited from this instructable.
I like the idea of using RJ-45 connectors. I really would give you loads more versatility with the concept.

Holy moly, my EL Escudo looks way different than yours!! Plus you seem to be able to light all the channels. When did you order yours? Nice looking results!
ctuck ctuck1 year ago
Aha it's the Dos! A new model that looks much more improved over the first. Guess I will be making anew SparkFun order! I can finally make my 8 Segment EL Wire project work!
dovadil (author)  ctuck1 year ago
Yeah, from what I have read, the Dos was a huge improvement.
ctuck dovadil1 year ago
Sure looks like it. I ordered one last week, should arrive soon. I have lots of EL projects I was really hopeful for that were all dashed by the week EL Escudo. The Dos should be a pleasant change.

GROOVY!!!

I want one!!!!!!!!!!

Also it’s a great conversation starter!
dovadil (author)  J-Five1 year ago
You have no idea :)

Next, try making an entire outfit with them. That would be VERY intresting.

GREAT idea, i wanna have a shot of making it, but with a more compact remote design, and maybe some light material to cover the lights, so they aren't visible til they are on :)
dovadil (author)  jsargent11 year ago
jsargent1 - Thank you.
Yes, the remote - I find the size to be okay, but this hat was my first full Arduino project and at the time, it was made before I explored wireless and XBee options. Obviously having less cables would be ideal, but with the time restriction of getting the build done before a festival, I decided to go down the route I knew the best, and this was using wire.
Also, if the hat is made quite tidily, it actually looks quite psychedelic, even during the day.
During your recreation, please let me know of any improvements/short-cuts along the way on my Orangeboard.
Cheers,
Dovadil

Awesome !!! nice detailed explanation.
dovadil (author)  Q2WERTY1 year ago
Thank Q2WERTY. This Instructable was composed and published only after I had built this psychedelic fashion accessory, so I have tried to be as detailed as possible.
I hope you manage to make use of some parts of this build and make something of your own. I have learnt a fortune from instructables.com (without which, this concept would never have materialised)

This is AMAZING!! Dovadil are you single??
dovadil (author)  mnurek1 year ago
Thank's mnurek - I'm flattered, but this isn't really the right place for this type of conversation ;)

This is AWESOME!
I hope you win

Might wanna put a low pass filter on the microphone otherwise when there is loud music playing its just permanently on.
dovadil (author)  pietzeekoe1 year ago
Thank you for this tip. That is a really good idea. I will probably implement this into mk1.1
Nice Hat! I might make one for a party!

Cool - go for it. Was definitely worth the effort.
