CoderDojoDC is part of the global CoderDojo movement of free coding clubs for young people.

MaKey MaKey Next Meeting

The theme for next meeting is MaKey MaKey, so bring yours or use one of ours to make something new and creative with your Scratch, Scriptcraft, or any of your projects. RSVP at

Turtles and Fractals

We went from turtle graphics to fractals all in one meeting. Whoever said that you couldn't create fractals in Scratch was wrong. They weren't fast, but we had a lot of fun drawing patterns using Scratch while waiting for the Mandelbrot fractal to finish.

Virtual Merit Badge

2014 Maker of Merit Badge

CoderDojoDC is proud to have been singled out with a "Maker of Merit" award for our booth at the 2014 Silver Spring Maker Faire, and we thought it would be nice to share the badge with everyone who helped out. So to all our helpers, here's a virtual badge that you can copy and post on your webpages and blogs.

See you next Sunday at the Elks' Lodge in Rockville!


Thanks for a Great Maker Faire!

Thanks to everyone who came out on Sunday (09/14) to help, or just to visit, our booth at the 2nd Silver Spring Maker Faire! The event was a great success, thanks to all the hard work of our volunteers, especially the kids who did such an outstanding job teaching others about binary numbers. Not only were we able to spread the word about our club and generate a lot of interest from vistors to our booth, we were also one of only a handful of exhibitors to receive a "Maker of Merit" award from the event organizers — another testament to the fantastic job our members did with their teaching and outreach activities! Great job everyone!

We are looking forward to our next meeting (9/28), which will resume on our regular schedule (every second Sunday, 3-5 pm) at the Elks Lodge in Rockville. The meetup site has full directions and other logistical details. See you there!

Join us at Maker Faire Silver Spring!

We won't have a dojo on September 14th, since we'll be at Maker Faire. Admission is free and it's at our former meeting location at the Silver Spring Civic Building. Stop by our booth where we'll be showing off projects and running a coding activity.

Interactive Fiction!

Remember Zork from the 80s? Choose-your-own-adventure books? Interested in writing story-like games that your friends can play?

Learn how to combine your story ideas with programming with our introduction to programming interactive fiction. Melissa Ford will show everyone how to get started with Twine, a very simple program that grows with the programmer's abilities.

Lava Arrows with ScriptCraft

It wasn't easy, but once a few people got ScriptCraft installed at our July 20th meeting, they had lava arrows. Here's a screencast of their script. Thanks to @westgardja for the activity and Alexa for making the video!

Summer CoderDojo

Thanks to the Elk’s Lodge in Rockville, we’ll be able to continue meeting over the summer! Join us every other Sunday from 2 PM to 4 PM to work on Scratch, Arduino, Minecraft, and Python projects. Details and signup are on meetup.

Kids Can Do This

One of our members, Becky Button, got an article published in the New York Times about programming and CoderDojo. Way to go, Becky!

RM Robotics Visit - June 8

Several members of the Richard Montgomery High School Robotics Club will be joining us to teach everyone about robotics and give a tutorial using Lego NXTs. The team recently competed at the FIRST Robotics world championship event and were awarded a 2nd place overall ranking. About 2800 teams from around the world compete in their division, so this is no small accomplishment. They’re also bringing SheRMan, their FIRST Robotics robot, and will let the kids drive it around as time permits. SheRMan is a pretty cool robot, so adults in the group may also be interested in some of the finer pointsx of its design.
