Things We Sell ! Wearable Electronics : Lilypad

A regular blog series featuring quick overviews of the various platforms Elmwood offers.

plushie

Intro to Wearable/Sewable Electronics aka 'e-textiles' with Lilypad.

  • Conductive thread instead of copper wire or circuit board traces.
  • Sewing
  • Fun !

Lilypad Ecosystem { SparkFun promoted Wearable platform }


    Out of the Box :

    Featuring a novel 'protosnap' approach: you test your circuits on the board & then snap them off & sew into your project when ready.
    Lilypad has many kits & options.
    Full range found here

    All Lilypad products are Ardunio IDE based.

    Kits have a very quickstart approach & can get going immediately.
    Protosnap kits generally don't require any programming, the other boards are more versatile. 
    We recommend you try some of the kit projects & then move to individual component based projects.
    Individual Boards :

    USB Based.

     

    FTDI Based

    * FTDI cable versions came before USB ProtosnapPlus boards.



    Suggested Companions Out of the box:
    Inventor of the Lilypad : Dr. Leah Buechley

    Intended Use :

    Learning & creating wearable electronics.

    If you want to start with ready made, little-to-no programming kits,
    with lights and touch, go with lilypad protosnaps.

    Things We Sell ! Raspberry Pi

    A new regular Blog series.
    Featuring quick overviews of the various platforms Elmwood offers.

    rpi3b_plus

    Product : RaspberryPi

    Wikipedia

    Current model: 3b+

    { speed similar to Apple A8* chip with integrated wifi }

    Previous models:

    rPi1B, A, B+, A+, rPi2, zero, W, WH, 3

    Out of the Box :

    Plug into an hdmi monitor with a USB keyboard & mouse
    & cheaply do linux computing / electronics control / STEM.
    Pop the NOOBS SD-card in & power on with a monitor & keyboard & off to the races.

    Super easy process to install Raspbian (OS).
    NOOBS SD card allows you to choose a variety of operating systems,
    such as the recommended Raspbian Educational Distro (*free* Mathematica, Minecraft, Python) or other specific use options, such as home media server (OSMC, libreelec/kodi).
     
    Most people will want to go with Raspbian, the default OS provided by the raspberry pi foundation.

    SD Card

    Our many Bundle options here!

     

    Intended Use :

    Learning computers without destroying Mom or Dads MacbookPro.

    There are many amazing pre-installed tools such as Scratch, Python and Mathematica, that can grow with you as you learn & skills increase. 

    Not really a full desktop replacement, but think of it as a versatile family learning environment.

    Or a hackable smartphone circuit board (with no built in screen or calling ability).

    Also if you can fit it, someone has put a Raspberry Pi in it

    Or, if you have an advanced project in mind:
    Full list of operating system choices.



    Performance :

    For LEARNING computing, rPi it is an excellent platform.
    Using a web browser on anything less than a 3b is a patience building exercise.

    For the detail oriented, generic 'by component' comparison

    * Processors are never really directly comparable, but for the daring...


    Hackery :

    If you are anti-monitor can TTL into the PI via a simple USB/TTL cable

    Overclocking is possible on some models.
    Heat Sinks available here.

    Good generic platform for about anything you can imagine. 

    If you want to prototype for mass production later, start with Arduino.
