Spanning Tree is a DC-area feminist hacker/maker space. We welcome people of color, trans women, genderqueer/genderneutral people, and people with disabilities.
As if National Maker Faire wasn’t enough, the weekend of June 20th and 21st is going to be jam-packed with Spanning Tree events.
Then on the 21st, we’ll be meeting at Creative Colony to learn how to create an LED cuff or brooch with Threadwitch (aka Sally Byers), a maker known for her skills combining traditional textiles with Adafruit electronics. RSVP here, as there are only EIGHT spots available in the class. We’ll provide you with all the materials for this beginner’s-level class, but participants will need to know basic hand sewing such as how to thread a needle, tie a knot, and sew a running stitch. Check out this video of Threadwitch’s Volcano Coat and other projects:
We’re proud to announce that we’ve been accepted to the 2015 National Maker Faire! We’ll be holding a Meet + Make where we’ll show off this year’s LED and yarn crafts. RSVP here and get updates about how best to find us at the Faire.
Spanning Tree is on the hunt for volunteers! Have you ever wanted to…
- Teach a class?
- Interview DC makers of all shapes and sizes?
- Help with fundraising?
- Run a table at a makerfaire or craft event?
- Organize a Meet + Make?
…then come to our next “open house” Meet + Make on May 24th and learn what it takes to get a feminist makerspace up and running! Can’t make it? Email Erica, our event coordinator, at firstname.lastname@example.org, and let us know how you want to help!
On Saturday, April 25, 2015, Spanning Tree made its inaugural appearance at the Robot Fest celebration of the creative use of technology.
This annual event features dozens of exhibitors showing off not only robotics from R2D2 to unmanned aerial vehicles and everything in between, but also 3D printers, soft circuit fashion, microcontroller workshops, vintage electronics, amateur radio equipment, electronic musical instruments, and more. It’s held at the National Electronics Museum in Linthicum, Maryland, which houses decades worth of creative engineering and showcases technical advances in science and engineering.
Along with information about our organization, Spanning Tree representative Katie brought a karakuri automaton she built from a kit. Originally made in Japan from the 17th century to 19th century, these pre-electronic robots used clockwork mechanisms to perform actions, sometimes even interacting with their environment, as in the case of the tea-serving robot she brought. Using only gears, cams, springs, and levers, it moves in a straight line for a set distance, moving its feet as if walking, and then bows its head. This signals that the tea is served, and the doll stops when the cup is removed. When it is replaced, the robot raises its head, turns around, and returns to where it came from. Robot Fest attendees were very interested in this demonstration of “old school” robots, prompting discussion of craftsmanship, ingenuity, and the meaning of the word “robot” itself.
Here’s a short video of the tea-serving robot in action:
At yesterday’s Make Afternoon, we assembled our cloud chamber out of a glass container, an old projector, and some very flamboyant duct tape.
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:
Would you like to sign up for a monthly donation?
Donations help us rent spaces to make more cool stuff in (and keep us in tea!)
Our first-ever Make Afternoon featured many awesome things and projects. Highlights included:
Sewing machines and soldering irons.
An embroidered spaghetti plot.
And lots of LEDs and textiles.
We’re thinking of doing one of these every other month, so watch our Meetup group for the next one!
Join Spanning Tree for our first ever Make Afternoon on Saturday, January 17th. We will be meeting at 1:00 pm in room A-9 of the Martin Luther King Jr. Memorial Library for an afternoon of making, crafting, and getting to know each other.
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. )
