Four years ago I had a dream which I only vaguely remember now, but I wrote it down in a dream diary. The next entry in this diary is on 3/5/11, and I started keeping the diary in 1994. Yesterday I was looking up another more recent dream and stumbled on this one again. I thought about my experiences over the past year and it made me see this dream in a completely new light.

In January of this year (2011) I first started working with LEDs and other electronics. December 2010 was when I first got the idea to do this; before then it was nowhere present in my consciousness. I frequently have problems with my LEDs flickering and/or not working and it is extremely frustrating because I haven’t had much success in figuring out what is wrong; I replace lights and wires and they still won’t cooperate. I also broke someone else’s lights recently, and I want to remedy that.

Here is my dream from 9/27/07:

****

“My lights don’t work!”
I woke up trying to say this loudly. My dream had ended with me turning on lights in my bedroom (different layout but with some lights like in the guest bedroom). The lights wouldn’t light up, and I felt it was due to the bulbs (obvious) yet at the same time, felt frustrated that I was always changing the bulbs, yet the lights were always burning out the bulbs quickly. When I tried to speak the words in the dream, my voice didn’t want to work either, which is why in life I spoke it loudly and forced.

Also in the dream, before turning on lights I was trying to hit the wall for some reason, and my impacts seemed unfocused and I could barely feel it and I figured the wall could barely feel it. And before that, I was with some others, it was kind of half first-person and half third person, but I was wanting to listen to some certain music (Heart, CCR?) and my partner/boyfriend/husband wanted to listen to something else, and there were others there too. This half-self sort of pissed off the others; another different first person of me saw this and wondered, possibly out loud, why I/she didn’t listen on headphones and take a break from the situation (and him too) and not only would we both get to listen to what we wanted but also would have the benefit of a break.

****

Some notes I made at the time after thinking about this dream:
The earlier part (about the lights) I woke with the feeling of being numb, fading. Wonder if it has to do with (if dreams have meaning) my wanting to not be in people’s way, or just a feeling of fadedness or lack of interest or something. Yesterday I almost caused a head-on collision at a confusing intersection while driving.

Last weekend I was at Apogaea, Colorado’s regional burn. Similar to Burning Man, but just for Colorado. For those of you still asking “what’s that?”, the website says “Apogaea is a collaborative outdoor arts and music festival held in beautiful mountains of Colorado.” Not sure that really covers it all, but it’s a start. It was my first time (they affectionately call us newbies “virgins”), and while I can agree with the above description, it was a lot of other things too. It had the art and the music – mostly electronic music, loud and entrancing until dawn – but also community, collaboration, celebration, fire (burning effigies at the end), things that light up (LEDs/EL wire/blacklights/flourescent paint and materials etc.), interesting activities (I especially liked the High Flying Aerial Acrobatics workshop, Camp Wardrobe Malfunktion was fun too), people in costumes, etc. In short, lots of different things to sink one’s teeth into.

In the days before heading off I made a Day of the Dead costume. While I’ve normally been adding my pretty little LEDs to Goodwill-hunted merchandise, this one was something I designed and made from a raw sheet of fabric, something I haven’t done in a while. Not intending to leave it unLEDed, I placed 1.8mm red LEDs in each of the eyes. The effect was so illuminating that even Facebook thought one of the skulls was a person and asked me to tag them! LOL. I was kind of rushed getting it done, no time for lining on this one, but it held up ok considering. My Rainbow Raincoat, Smolder dress and Flower Power dress also came along with me and showed their colors.

I camped with some friends I met through the Boulder Hackerspace who created the Musical Universe of Faux Fur Flowers (MUFFFs) – a sound-interactive art installation with LED strips, faux fur, bent pipes and flourescent paint. It was fun helping with assembly and take-down, and also joining the cuddle-puddle I found one night lying underneath enjoying the lights react to the music and their conversation! Here’s some videos of the MUFFFs in action: Cuddle puddle or with drums

And here’s some photos from the event:

The weekend before last (May 21-22) I attended Maker Faire, the “World’s Larges DIY Festival”, in San Mateo California.

I was proud to be a part of the eTextiles / Wearable Computing Lounge and Showcase. eTextiles and Wearable Computing (which I’ll abbreviate eT/WC from here on) incorporate electronics into fabrics or clothing. See my earlier post for more on what it is and how I came to be interested in this field.

The Lounge displayed the works of about 10 or so designers. The Showcase was an eT/WC fashion show, held at 3 pm on Saturday on the ArcAttack stage of the Fiesta Hall. I never imagined myself as a runway model and although it wasn’t exactly like that, I sure couldn’t pass up the opportunity to sachey, chantey!

(Did anyone capture the Showcase on video? My Mom especially wants to know! )

For the Lounge, I had on display the 3 items mentioned in my May 9 post: the Rainbow Raincoat, Smolder and Flower Power dresses. For the Showcase I decided to wear Flower Power, but I’m also proud that Lynne Bruning, who brought us the eTextiles Lounge + Showcase, chose to wear my Rainbow Raincoat while presenting! (I should have warned her the fabric is very insulating and not so great for stressful situations, though!)

I was happy to meet many interesting and fun fellow designers and see how each of us is taking the technology and creativity in different directions. Very exciting times! Thank you Lynne for making this event happen!

In addition to my eT/WC participation, I was gobsmacked just walking around the Faire taking in all the sights, sounds, tastes and thought-provoking ideas! It kind of felt like the county fairs I used to go to as a kid combined with Mythbusters and Mad Max.

I will be attending Maker Faire in San Mateo, CA this month and am excited to be a part of the eTextile and Wearable Computing Lounge and Showcase organized by the Textile Enchantress Lynne Bruning! I plan to have 3 items at the Lounge and will need to pick one for the Showcase. Each of these items share a common theme:

• the original garment was purchased at Goodwill
• it is lit up by individual LEDs
• telephone wire was used in the circuitry

Fiesta Flower Power
They say “beauty is the best defense against complexity”. Who needs brains when you have elegance and simplicity? Less can indeed be more! A coin cell battery powers 43 tiny 1.8mm white LEDs evenly dispersed on this blue floral print dress. No Arduino or LilyPad.

Rainbow Raincoat
This was my first project in wearable technology, completed in March 2011. Diffused 5mm RGB LEDs adorn each of the 10 buttons on this shiny black coat. Each LED is surrounded by crystal beads for accent and additional diffusing enjoyment. Controlled by an Arduino Duemilanove. A button lets you choose either color drift mode for the subtle approach, or switch to rainbow mode when you want to wow friends and complete strangers alike (and/or try out light painting…).

Smolder

Inspired by a dream, a Facebook conversation and a look, hot and cold compete for attention on a little black dress. Diffused 5mm RGB LEDs are set simply to glow ember-orange, but with the timing and intensity cleverly crafted to mimic the look and feel (well, maybe just the look) of a campfire’s glowing coals. Controlled by a LilyPad, making gratuitous use of the Arduino language’s random() function. NOTE: I’m still working on this one but hope to have a photo up in a few days!

For the Showcase I will either exhibit the Rainbow Raincoat or the Smolder dress.

Look up the word redundancy and you’ll find a bunch of negative-sounding synonyms like repetition, duplication, excessive, superfluous, no longer necessary… but also a few positive phrases like ‘alternatives in case of failure’, ‘circumvent transmission errors’, etc.

True to the definition, redundancy is often perceived as something negative and wasteful. And it can be. But sometimes it saves your ass! I like to call those instances where redundancy is helpful and necessary cases of “smart redundancy”.

Electronics is definitely one of those saving places. I’m finding this a lot lately as I grope my way around putting LEDs on clothes. I’m a relative noob at this, having made only 2 LEDs-on-clothes projects so far. One thing I’m realizing is that to really make this work I need repetition and back-up-plans, because failure is just too likely in a number of ways.

For one, what you use to connect the LEDs to each other and to your power source and microcontroller could stump you. For both of my first projects I’ve used phone wire – already insulated, light-weight, and free because I already had a bunch on hand. But another good thing about phone wire is there are multiple strands of copper wire. A friend of mine tried a project with only single-stranded wire and found it flaked out on her all too often, plus the LEDs were not as bright.


The circuit itself is something else where I have yet to figure out how to work in the right type of redundancy. One LED shorting out can sometimes bring the whole thing down. Finding the problem LED(s) can prove difficult too.

My biggest dilemma is finding solutions to these sorts of problems. What’s the point of putting lights on clothes if the lights don’t work?!

Of course redundancy can have its dark side – such as supporting duplicative databases at a large corporation anxious to please its shareholders. But even then you’d better have a backup plan and sometimes you find hidden misconceptions and learn things you wouldn’t have known if you weren’t consolidating. You also need to decide how much redundancy is enough based on your situation. Being locked out of my garage because my backup opener failed tells me either I didn’t have enough redundancy and/or I shouldn’t have blown off fixing the first one!

I’m not much of a football fan, but being that my home state made it to the Super Bowl this year I decided to tune in while I went about my business that day. Maybe I’d see some neat commercials, I thought. At halftime a friend chatted me to ask if I was watching it because there was quite an LED show going on.

If you haven’t seen it:

Here is a summary of what I could dig up on the technology and some of my personal opinions about the visual aspects of the show.

How they did it

• almost 400 of the backup dancers wore LED-equipped costumes
• the costumes were made of durable silver tricot foil by a dance/costume company called Just for Kix in Baxter, MN
• each dancer’s costume was outfitted with 300 LED RGB strip lights supplied by Creative Lighting Solutions, LLC in Cleveland, OH… so, over 100,000 LEDs just in the dancers’ costumes
• velcro was used to affix the LED strips
• the LEDs on the dancers were set up to produce 3 colors only: red, green or white
• power was from a 12 volt battery pack with belt controller
• the dancers manually controlled their lights
• the cube-heads and the Black Eyed Peas costumes’ electronics were made by Engineering Solutions, Inc in Lehi, UT, under some direction by Creative Lighting Solutions

My opinions

• Likes:
  • how the combination of the LED strips and the type of fabric in the costumes made the dancers’ entire bodies glow
  • the surrealistic feel when the dancers formed moving arrows
  • the cube-head dancers looked really funky – I think the combination of costumes, dancing and music were more than the sum of the parts there
• I suppose one could argue that the lights shouldn’t eclipse the singers, but in general I thought the Black Eyed Peas’ costumes could have had some more imagination as far as the LED enhancement goes – color, patterns, patterns in motion, etc. I think there is great opportunity to use all 4 dimensions and color with this fashion / lights / technology mixture.
• Choreography of the dancers forming hearts and arrows: why not combine these and have the red hearts only at first, then have one-person wide white arrows pierce the hearts… or, make the hearts appear to beat in time to the music (maybe they were supposed to look like they were beating but it looked more like swaying to me).

All in all I thought it was great to see so much wearable tech in the Super Bowl.

When I was a senior in high school I had plans to be a fashion designer. I earned some college credit in fashion attending the School of the Art Institute of Chicago one summer. I designed and made some of the clothes I wore. I applied and was accepted to attend the Fashion Institute of Technology in New York City.

Then I, well, I think perhaps, sort of chickened-out. Or maybe I just decided to explore some other things I liked first; I’ve always struggled with juggling multiple interests. I ended up studying math at a university in the same state I grew up in and then worked as an actuary for 14 years. Then I quit and the last couple years I’ve been teaching myself various programming languages and tools with the goal of transforming myself into a web developer.

This past weekend I got to experience a little taste of what it would have been like if I had stuck with plan A, mixed it with a bit of plan C, and added some seafood sensation and secret sauce.

I attended a 2-day workshop titled “Where Electronics Meet Textiles”, put on by award winning textile artist Lynne Bruning and Italian eTextile Master Troy Nachtigall. About 17 attendees from various backgrounds learned about the latest innovations, the materials and disciplines involved, and at the end we were left to our own devices, so to speak, making something of our own choosing (actually and thankfully we had a lot of help from Troy and Lynne!).

At the heart of eTextiles, wearable computing, etc. is often a LilyPad, which is a smaller, more elegant-looking version of an Arduino. These devices are a combination of electronics hardware and programmable software that allow you to transform physical inputs into different physical outputs. Think things like light, motion, sound, contact, etc. Combine this with fabrics, conductive thread or other material, and various other electronics hardware and you can create clothes that light up in response to movement or sound, convert sound or proximity of other objects to vibration, monitor body processes like heart rate, sleep, etc.

Our instructors Lynne and Troy complemented each other well in their strengths and interests. We also had a special guest: Nwanua Elumeze, founder of Aniomagic, who is developing some really innovative ways of addressing human-machine interaction. For example: uploading information to your device by holding it up to your computer screen, where patterns of light, sound or movement are used to send the information, rather than messing about with cables and not-so-basic instructions.

As mentioned, the afternoon of the second day was spent on building our own projects. I don’t know whether to feel guilty about this or encouraged that my life choices of late are on the right track, but I didn’t actually make it to the integrating-with-the-fabric part. I was too captivated with programming my LilyPad. But my new friends made a variety of items, most of which involved some sort of blink and bling. You can see some of it here.

The event was sponsored by SparkFun Electronics and PlugandWear and held at SparkFun’s offices in Boulder.

I’m glad my path has come round again and I’ve met up with with these other eTextiles pioneers; perhaps together we can explore the interstitial spaces where we will create magic and the impossible.
