Enginursday: To be a fly on the wall...

There’s a fine balance to walk in wearable electronics between form and function. You want as much utility as possible, and you like to imagine that someday, something you create will be as indispensable to someone’s life as a smart phone. But you also want to create something beautiful;…

Enginursday: Bling in the new year!

Another year gone, and if you’re anything like me, you’re thinking hard about what you want from the next one! For me, that means reflecting on the parts of 2013 that meant the most to me, and how I’m going to bring more of that energy into the new year. In 2013, I spent a lot of…

Enginursday: The Spark Arts

Here at SparkFun, we’re getting geared up to decorate for Christmas! Oh, wait. Sorry, that’s Target. Sometimes all of that red confuses me! WE are actually getting ready for Halloween, because that is the next holiday, and we are rational human beings. There’s one month left, which…

Hello, Harto!

Let’s have a short, frank talk about the lunches we’re eating at work. Hot pockets? Are you serious? In January of this year, right when we were resolving to kick the bagel bites and give Lean Cuisine one last chance, we had the good luck to encounter the Hello Harto Indiegogo campaign.…

Engineering Thursday - E-textiles Magic!

Have you ever had that moment, after you’ve sweated every detail, solved and re-solved every problem, and the project is finally done, when someone pushes the button, and - as far as they’re concerned - what they’re looking at is magic? They don’t see the hours you put into…

Engineer Thursday - Open-Bear Surgery at Olin College

A couple weeks back, the infamous Pete Dokter and I got the opportunity to take a luxurious* trip to the Northeastern United States, visiting Brown University, MIT Media Lab, and Olin College. While we were visiting, Amon Millner was kind enough to invite us to see first-hand what his students were…

Using the LilyTiny board

What I love about the LilyTiny and LilyTwinkle are how much they lower the barrier-to-entry for advanced e-textiles. The jump from extremely basic LED circuits to Arduino projects can be really daunting to those who have no programming experience at all. I should know, I had never looked at a…

My Love/Hate Relationship with Conductive Paint

Very soon after joining the engineering department, I had an idea. I thought it would be fun to do a much simpler riff on the gorgeous Living Wall by MIT Media Lab. I thought that mine would be approachable, something that anyone could look at and think 'Hey! Maybe I'll do that to my living…

LDK Experiment 1: Lighting Up a Basic Circuit

February 7th, 2013

The first experiment in the LilyPad Design Kit series. In this exercise, you will learn how a basic e-textiles circuit works, and light up a sewable LED using a coin cell battery holder and conductive thread.

Sewing with Conductive Thread

January 23rd, 2013

How to use conductive thread with e-textile components.
  • Tutorial - Basic Lilypad Tutorial | last month

    That’s wonderful! I’m so pleased, you should send a picture!

  • News - SXSW Create 2014 | about a month ago

    Well spotted! Charlie is particularly interested in wearables, and was sporting Adafruit’s Ampli-Tie. It’s a very cool project, and he put quite a lot of work into it.

  • Tutorial - Soft Circuits: LED Feelings Pizza | about 3 months ago

    Thanks for the feedback, Kabong! And you’re right- the larger needles are designed to work well with the standard LEDs, but the smaller needle is necessary for the micro LEDs. It’s fine to use either LED for this project, so if you find the larger needles easier to teach with, feel free to make the switch!

  • News - Enginursday: Enginerds in… | about 3 months ago

    GIVE us 19 years, jeez!

  • Product COM-11748 | about 3 months ago

    Using a microcontroller, you can make the whole string blink at whatever rate you’d like, but the LEDs are not individually addressable.

  • Tutorial - Using the LilyPad LilyTwinkle board | about 3 months ago

    Shouldn’t be a problem as long as both switches are turned to ‘on’! If they are, and you still have problems, you should definitely email techsupport@sparkfun.com!

  • Product KIT-12073 | about 4 months ago

    The kit is designed to walk through a specific set of experiments, and includes the parts necessary to complete them without tearing apart any of the circuits to reuse the parts. I completely agree that if you’re ready to start programming and using sensors, the ProtoSnap Dev Board is the way to go, but this kit is a precursor to those skills. It walks a beginner through the basics of circuit building and sewing in preparation for those more complicated circuits! You can find the experiments the kit is built around here

  • Product DEV-10081 | about 5 months ago

    Glad I could help! <3

  • Product DEV-10081 | about 5 months ago

    Parallel from the pin, and no additional resistors if you’re using the LilyPad LEDs. If you use standard 5mm LEDs, you’ll want to add resistors! I don’t have a tutorial right now that shows more than one LED per pin (but I’ll take it as a suggestion!), but here’s one that shows the circuit using multiple pins. To add more LEDs to the same pin, just continue to connect the positives to the pin and the negatives to ground. https://learn.sparkfun.com/tutorials/protosnap-lilypad-development-simple-hookup-guide/raygun-preparation

  • Product DEV-10081 | about 5 months ago

    I doubt you’ll have any trouble putting several LEDs on each pin. They’ll be brighter or dimmer, depending how many pins are active at that moment.
