We then gathered in the glow to look for particle trails. As Katie said, looking for the “tails” left by cosmic particles was more like looking at the night sky for shooting stars–you’re barely able to register that you saw one before it’s gone–but we managed to glimpse several before the dry ice melted.
As an added bonus, Threadwitch Sally Byers also showed up to work on her LED fashion. In this photo, she models her hat with the chemical symbols for chocolate picked out in beads and blinking LEDs. (Watch it in action here!)
This March, as a special project for our Make Afternoon social, we’ll be making a cloud chamber. Invented in 1911, it’s a tool that makes cosmic particle visible to the naked eye as they travel through a cloud of alcohol vapors. We’ll be able to identify protons, electrons, and many other particles by the trails they leave as they travel through the mist:
This is the perfect place to finally finish those knitted mittens, put the finishing touches on your personal website, or learn how to solder. Bring a project to work on or just yourself. We’ll have tables, snacks, plenty of outlets, and — if our plans work out — wi-fi.
Additional equipment available for use: a sewing machine, extra knitting needles, a button-making device, a soldering iron and glitter glue. (If you’d like to bring artwork for buttons, try to fit it within a 0.875″ diameter circle — but leave plenty of margin around that, it will be set up to make one-inch-diameter pin-back buttons. )
Have you been wishing you could make awesome animated GIFs just like they do on Buzzfeed? Well, wonder no more! This hour-long class will show you how to create your very own GIFs using Photoshop CS6 and Quicktime. RSVP here.
During this hour-long class we’ll explain everything you need to know about how different kinds of 3D printers work, give demos of 3D design programs that you can use to create your own items, and finally show you how you can have your design printed in plastic by MLK’s 3D Print Crew! RSVP here.
If you missed it last month, we’re teaching this class again! We’ll show you how to create a simple bracelet digitally using TinkerCAD, then walk you through the process for getting it printed in recyclable plastic by MLK’s 3D Print Crew. RSVP here.
Tired of turkey prep and want to learn something new? Erica Stratton is teaching free tech classes at the Martin Luther King Jr. Memorial Library this month. She would like to invite all Spanning Tree members to participate in her next class, “3D Printing: Jewelry Design”.
Erica will show you how to create a simple bracelet digitally using TinkerCAD, then walk you through the process for getting it printed in recyclable plastic by MLK’s 3D Print Crew. The class is this Wednesday (November 26th) so be sure to RSVP now!
Happy Ada Lovelace Day! This is an international day celebrating the achievements of women in science, technology, engineering and maths. Do you know what pioneering woman in technology is referenced by our name, Spanning Tree?
The answer is Radia Perlman, a software designer and network engineer. She is most famous for her invention of the spanning-tree protocol (STP), which is fundamental to the operation of network bridges.
HacDC will once again be hosting us for this four-hour class. You won’t need to know code to take this class, but it’s recommended that you bring a laptop so that you can follow along. Be sure to RSVP here!
Our students turned out to be a very diverse group. We got people of all ages and backgrounds, united in the quest to learn how to knit. Once they figured out casting, we settled in to talk about the difference between English and Continental styles, the proper way to hold a needle (“Like you’re going to stab someone!”) and how knitting patterns are like programming languages.
“It doesn’t matter, yarn happened.”
Mackenzie demonstrating the Continental style of knitting: “Knit like you’re from France!”
People have already begun asking if we’re going to do a basic sewing class. We just might!
