E-Textiles – Sewing with Electronics Jan 3rd, and 4th AfterAction

Event was Jan3-4th 2013 and was AWESOME!!

After Action Review: Theo arrived about 430pm at airport.  We grabbed some food and got to the space about 545.  We had a whole lotta new folks and several we had not seen in awhile, as well as regulars.  Thurs night turned into a lot of overview of e-textiles and talk – along with a 1/2 doz other things happening around the space.  Theo couch surf’d at Makers East (my home in Haiku) and after breakfast at Market Fresh Bistro (my fav food) we were back at makerspace by 1130am (yeah a bit late but we’re on maui time.).  There were 3-5 people who returned to learn programming and more details of the Lilypad/Arduino.  Lots of inspiration and sharing. (class material and more on Lilypad is at the Learn.Sparkfun.com site)  We have decided to have an Arduino Corner at our Thursday Meetings for people to share experiences and learn more.  This may evolve into its own night and/or weekend daytime meetup.  We shall see.  Here are some pics of the event…

Sewing Microcontrollers and Electronics? Yes!!!
Maui Makers is pleased to host a vacationing elf from Sparkfun Electronics who is bringing several ProtoSnap LilyPad Developer Kits to give away at our Thursday Jan 3rd public night 6-9pm in Pu’unene. (The Elf is available Friday Jan 4th daytime to continue if people want to do so)

Sparkfun’s ProtoSnap LilyPad DevKit

Come down and learn how to program a microcontroller, make LEDs blink, motors vibrate, sense light/temperature… and then sew it into your clothing! Event and kits are free. Limited number of LilyPad Dev Kits are available on first come-first receive basis.

For directions, etc. see map etc in right column or the info page on Thursday Night Meetings

About the LilyPad Dev Board…

“The ProtoSnap LilyPad Development Board is designed to get you started in the world of e-textiles. Combining a LilyPad Simple Board with other LilyPad components like a buzzer, a vibration motor, an RGB LED, a button, a switch, five LEDs, a light sensor, and a temperature sensor, the ProtoSnap LilyPad Development Board lets you dive right into wearable electronics. When you’ve learned how to program the LilyPad Arduino Simple Board, break apart the components and explore the power of the LilyPad platform.”

Basically an Arduino board with sensors/effectors built into board, that you can later snap apart and sew back together on clothing… conductive thread included!!!

What can you do with e-textiles?   Well check out the examples this new article just posted by MAKE magazine

Many more examples abound on the web..  start here (http://www.lbruning.com/etextiles) or here  (http://www.adafruit.com/blog/category/wearables)

How do you sew electronics with conductive thread? Check out the post I did earlier this year on our class at the Hawaii Stem Conference.

    Hey Jerry, I want to thank you for setting up the awesome class with the Lilypad. I had no idea they were going to be giving them out. I was purely coming to say hi to everybody and plug back in after being away for so long. it was a real treat to get yet another Arduino programmable toy to invent with**! so thanks again for putting it altogether and planting the seed for growing The Makers of Maui!!

    ** earlier that day I had been thinking about installing a break beam alarm to let me know if my housemate is coming up the stairs; then THWAP!!! ZINGO I go to your class and walk into instant karma: the Lilypad developers board had that one already programmed in!

    A Hui Ho

    I made a few changes to some stock code for the ProtoSnap LilyPad Developer Kit board to turn it into THE SOUND for an ELECTRONIC DOOR KEY, Unlocking the door (or whatever you imagine). I have picked values that produce a nice rising or dropping of tone as the flashlight passes of the light sensor.

    Here’s the SKETCH. NO OTHER REQUIREMENTS except passing a flashlight over the sensor:

    ——– fwd ————-
    Pitch follower

    Plays a pitch that changes based on a changing analog input

    * 8-ohm speaker on digital pin 8 (I just used the piezo onboard)
    * photoresistor on analog 0 to 5V ( Photoresister onboard, pin A6)
    * 4.7K resistor on analog 0 to ground (didn’t worry about this)

    //the tone kicks in when serial readout is > 16

    This example code is in the public domain.



    void setup() {
    // initialize serial communications (for debugging only):

    void loop() {
    int ledPin = 10;
    // read the sensor:
    int sensorReading = analogRead(A6);
    // print the sensor reading so you know its range
    // map the analog input range (in this case, 400 – 1000 from the photoresistor)
    */ (Peter Rosen changes marked with ** Modified values to operate in low light without buzzing)
    // to the output pitch range (120 – 1500Hz) **Pitch Extended
    // change the minimum and maximum input numbers below
    // depending on the range your sensor’s giving:
    int thisPitch = map(sensorReading, 100, 500,1000, 5000);
    pinMode(ledPin, OUTPUT);

    // play the pitch:
    tone(7, thisPitch,3);
    delay(6); // delay in between reads for stability


    Anyways I liked the sensitivity and sound made by passing the flashlight, slowly over the sensor to make a very science fiction like sound. Enjoy.
