yes, you will want to use a pull-down resistor otherwise you will have a floating voltage, making for a rather flakey button.

Conductive thread made from stainless steel has low resistance compared to others on the market.  Check out the variety that offers.  Here is a thin thread that is only 9 ohms per foot:

Note that conductive thread when used in the sewing machine should only go in the bobbin and never as a top thread, as it will fray and break otherwise.  In the bobbin it is able to lay flat against the work.

You could have a wireless radio transceiver send a message to its pair connected to an Arduino and a 3G shield. You can then send a pre-programmed SMS to whomever upon the event trigger.

You need to consider the power consumption of the sensors as well, as well as how much current the IO pins can source/sync.

The trick to working with a manageable current requirement with muscle wire + Arduino is to play with the duty cycle in your code: that is, playing with the HIGH/LOW duration.

The main difference between the Lilypad Arduino and the Lilypad Simple Board is that the Simple Board does not have Rx/Tx pins (receive/transmit), which are typically used in wireless communication -- for example if you were integrating a Lilypad Xbee board to your design.  I believe it has less IO pins as well, if I am remembering correctly.    So yes, using a Simple Board for your project should be fine. 

The FTDI cable is essentially the same as the breakout board, and yes you can use this to program the board from your computer.

Given the number of LEDs you plan to use and the required power source, you will need to be using a transistor(s) on your banks of LEDs. A TIP120 will probably do the trick.  Consider wiring them in Series/Parallel arrays, as used in LED matrices. Consider also that conductive thread is quite resistive.  I always like to incorporate iron-on conductive fabric wherever possible, since resistance does not diminish over distance as with thread.  I cut strips of conductive fabric and then join them to components using a few looping stitches of conductive thread.

11  Community / Workshops and Events / Wearable Technology Classes in Toronto on: May 04, 2012, 06:18:16 pm
Hi all,
I'll be teaching a series of three workshops in Toronto, Canada , each related to Wearable Tech.  Please see below for the workshop descriptions.

Wearable Technology 1: Intro to Soft Circuits
When: Thursday, May 10, 2012. 7-10pm
Instructor: Erin Lewis
Price: $45 ($35 members) + materials.

About the workshop: Soft circuits are electronic circuits made wearable through the use of conductive thread and conductive fabric. In wearable electronics, circuitry design and application are made with the body in mind. This workshop will introduce you to the world of wearable conductive materials as well as specific techniques for their application on the body. You will learn to construct soft analog components such as wearable switches, flex and force sensors, soft pressure matrices and even fuzzy, directional 'stroke' sensors. You will also learn to think about the body and its movements in an entirely different way: as a means to actuate electronics! This workshop is great for crafters, makers, DIYers, electronic hobbyists, and anyone looking to include the dimension of the body and soft analog electronics into their projects.

About the instructor:
ERIN LEWIS is an emerging artist who is currently studying Integrated Media at OCAD University, with a minor in Wearable Technology. She works predominately with electronics and video in an installation setting. Erin has released video work with the National Film Board of Canada, exhibited work in Nuit Blanche, and conducted live video performances across Toronto and Europe. She enjoys grapes, kittens, and real-time data feeds.

Wearable Technology 2: Intro to Lilypad Arduino
When: Thursday, May 17, 2012. 7-10pm
Instructor: Erin Lewis
Price: $45 ($35 members) + $35 Lilypad hardware purchase

About the workshop:
The Lilypad Arduino is a programmable microcontroller specially designed for use in wearable tech and e-textiles projects.

In this workshop, we will introduce you to the Lilypad and its suite of sensors and accessories, teach you how to interface the Lilypad with soft circuits, and guide you through the basics of writing Arduino code to add fun interactive behaviors to your wearables projects. Hands-on exercises and a variety of example projects will be used to explore the exciting possibilities of this technology.

This workshop is suitable for people with no previous knowledge of the Arduino microcontroller, and is a good introduction to the world of Arduino in general.

About the material fee: We have made the option to include the cost of purchasing a Lilypad microcontroller and FTDI adapter in the fee. Because the Lilypad is designed to be sewn into wearables applications, we recommend that every participant in the workshop own their own Lilypad to work on and take home at the end of the workshop. The FTDI adapter allows your Lilypad arduino to communicate with your computer via a USB key. If you already have a Lilypad, then you can check the option to pay only the course fee, and bring your own hardware.

Wireless Communications: Xbee & Arduino
When: Tuesday, May 22, 2012. 7-10pm
Instructor: Erin Lewis
Price: $45 ($35 for members) + $55 Xbee hardware purchase

About the workshop:
Tired of being tethered to the computer? Make your projects wireless using Xbee radios! Xbees are low-cost, easy to configure, and offer reliable communication between devices. In this workshop we'll work in pairs and small groups to play with different possible setups using Xbees and Arduinos. We'll look at a wide range of art projects and hacks that use Xbees and Arduinos together, so you'll walk away with plenty of ideas for your new-found knowledge. This will be a fun, participatory workshop that will ultimately break you free of your dependency on being hard-wired.

About the material fee: This workshop will require that each participant have an X-Bee wireless module. Our hardware purchase cost includes the X-Bee module and an Arduino wireless/SD shield, which allows the xBee to connect to the Arduino microcontroller. This hardware is for participants to keep. We will provide Arduino microcontrollers for the class. If you already have XBee hardware, you can select the option to pay only the course fee.

You can always you thin strips of iron-on conductive fabric. The only thing you will have to sew would be the connection from the fabric to the Lilypad PCB. 
13  Community / Workshops and Events / Lilypad Arduino Workshop in Guelph, Ontario (Canada) on: February 26, 2012, 12:51:14 am
For those interested, I will be teaching a Lilypad Arduino workshop tomorrow (Sunday Feb 26th) at the Con-G Anime/Geek Conference in Guelph, Ontario.  It's a one hour introduction to the Lilypad body of components, as well as conductive materials and general Wearable Tech stuffs.  Come say hi!

Here is the link:
14  Community / Local Groups / Toronto Wearable Technology Meetup on: February 06, 2012, 09:40:38 pm
This Wednesday we'll be looking at robotic masks (involving conductive felt, servos, lilypads and the like), and discuss the topic of ethical making with a Fair-trade, Fair-Mine Goldsmith, Ryan Taylor.  Here is the event link, with details posted below:

The Toronto Wearables Meetup is a gathering of people interested in wearable technology, fashion, wearable electronics, soft circuits, electronic textiles, emerging materials, and other creative and innovative approaches to things that live on the body.  This Meetup is a gathering of artists, fashion designers, industrial designers, textile enthusiasts, engineers, researchers, students, and anyone interested in these emerging and intersecting fields.

Following the artist talks we will have a Show-and-Tell from previous speakers who will update us on their projects old, new, and in-progress.  Please note that this TWMeetup will be filmed by CBC, who are doing a short segment on the Toronto Wearables community.

Rachael Kess is a fibre student at OCAD University and she wants to START A HOLISTIC REVOLUTION. Working with the idea that BODIES ARE THE ONE THING WE ALL HAVE IN COMMON, Rachael likes to subvert technology in order to engage her viewers/participants in a critical dialogue about how BALANCE CAN BE FOUND BETWEEN BODY AND TECHNOLOGY. She makes masks and puppets using wet/needle felting, weaving and electronics and uses her electro-textile objects in performance, often while naked. Rachael started making masks and puppets in order to CONNECT HER TEACHING/HEALING PRACTICE WITH HER CREATIVE PRACTICE. When not naked and masked, Rachael teaches yoga and practices Thai yoga massage fully clothed.

Ryan Taylor is a graduate goldsmith, chief designer & co-founder of the Fair Trade Jewellery Company (FTJCo) which by Valentines day 2011 was the only company in North America, and only one of a handful internationally to produce using Fairtrade Fairmined Certified gold. Ryan’s documentary about these metals 'The Last Gold Rush' is available online:

He currently sits as Co-Chair of the Responsible Jewellery Council’s (RJC) Standards Committee which has published the industry’s first Chain of Custody system for Gold & Platinum metals, and has recently taken on the role of Chair for the RJC’s sub-committee on Diamond Chain of Custody.  In March Ryan will continue his work visiting artisanal Diamond miners in Central African Republic & Liberia with the US State Dept. & USAid as part of a program called PRADD (Property Rights and Artisanal Diamond Development). An initiative much like Fairtrade Fairmined which could improve the lives and rights of workers and their communities.
