the collar, made from copper conductive thread and powered by the LillypadMP3.\u00a0 I&#8217;m still waiting on fabric samples, so I haven&#8217;t finalized the materials yet.\u00a0 I did assemble a very successful test speaker:<\/p>\n<p><iframe loading=\"lazy\" width=\"584\" height=\"329\" src=\"https:\/\/www.youtube.com\/embed\/KU5lUTkLsAY?feature=oembed\" frameborder=\"0\" allowfullscreen><\/iframe><\/p>\n<p>I was very pleased that this worked right out of the gate!\u00a0 The LillypadMP3 is the perfect platform for this application.\u00a0 In this test the speaker is far too quiet, due to several factors.\u00a0 Going forward, I will be adding interfacing to reinforce the fabric and get better vibration quality.\u00a0 I have stronger magnets on order that should help up the volume.\u00a0 Also, the final design of the collar will create a chamber to help amplify the sound.<\/p>\n<p>2) Inflatable dress:<\/p>\n<p><a

I had no idea that working with compressed CO2 was so complicated!\u00a0 I started with a very basic test using a CO2 bike tire inflator to verify the fabric would work:<\/p>\n<p><a href=\"https:\/\/www.youtube.com\/watch?v=QtaPZCPldJI\">https:\/\/www.youtube.com\/watch?v=QtaPZCPldJI<\/a><\/p>\n<p>Using pre-filled CO2 cartridges seemed like the way to go.\u00a0 What followed was research into a vast variety of areas, including paintball\/airsoft, fish tanks, life vests, cycling and rocketry.\u00a0 I&#8217;m pretty sure I now know everything there is to know about CO2.\u00a0 The final design I&#8217;ve settled on is to have a 90g CO2 cartridge in a neoprene holster on the thigh, which will connect to a high-pressure solenoid at the lower back.\u00a0 When triggered by the Arduino, via a MOSFET relay, this will inflate the hem through a hidden tube from the solenoid.\u00a0 I currently have almost everything to assemble this.\u00a0 I&#8217;m just waiting on hearing back from a solenoid seller to make sure I&#8217;ve chosen the correct valve.<\/p>\n<p>3) LightPrint top<\/p>\n<p><a

Kent State Hackathon.\u00a0 I&#8217;m going to use <a href=\"http:\/\/www.instructables.com\/id\/RasPi-w-Fadecandy-driver-WS2811WS2812-Addressable-\/?ALLSTEPS\">this tutorial<\/a> to create a top that is essentially color change on demand, utilizing a phone app that controls a RaspberryPi.\u00a0 I will also be coding in an override to create a bright color flash when the range sensor is triggered.\u00a0 While I like this setup, I wanted to use brighter LEDs than you find on the RGB strips.\u00a0 I ordered higher powered RGB LEDs and the <a href=\"https:\/\/www.adafruit.com\/products\/1378\">WS2811 driver chips from Adafruit<\/a>.\u00a0 And here&#8217;s where I encountered a slight setback &#8211; not having worked with SMT components before, I didn&#8217;t realize that I wouldn&#8217;t be able to just drop the chips on a breadboard for prototyping like usual.\u00a0 So, although I have all of the components, I have not yet been able to test this setup.\u00a0 I have on the way a <a href=\"https:\/\/www.adafruit.com\/products\/1212\">PCB<\/a> which breaks out the SMT connections to standard breadboard headers.\u00a0 This will allow me to do the necessary testing.<\/p>\n<p>This issue also got me thinking about how I&#8217;m going to assemble the final components, which keeping everything small enough to embed in the 3D printed neckpiece.\u00a0 I think I&#8217;m going to look into having custom PCBs made that I can mount the chips to which keeping things small.\u00a0 I can then also use SMT resistors, again helping maintain the small footprint.<\/p>\n<p>4) Hoodie sweater<\/p>\n<p><a href=\"http:\/\/blogs.discovery.wisc.edu\/projects\/files\/2015\/04\/HoodieSweater.jpg\"><img loading=\"lazy\" class=\"aligncenter

case, a piece of printing filament) inserted through the small hole in the spine.\u00a0 The spine will be attached to the garment by threading a thin string or thread through the pivot hole and the loose ends of the muscle wire will be threaded through the fabric, crimped and attached to the Arduino setup.\u00a0 When the muscle wire is triggered it will shorten, causing the spine to rise &#8211; similar to extending your finger.<\/p>\n<p>Miscellaneous:<\/p>\n<p>I got an tested new PIR sensors to use on all of the garments.\u00a0 I chose this particular style for it&#8217;s short reading range
