CoderDojo Wien Hackathon at WeAreDevelopers

Yes, you've made it to WeAreDevelopers! Now it's your time to prove you are able to take the toughest challenge a developer can face. Show that you're not only an expert but a master who can teach!

What the hack

You are free to let your creativity flow. Just keep in mind that your exercise should be solvable by a kid at the age from 7 to 17. Take a brief look here and see who an exercise can look like. We'll have a bunch of micro:bits with us, if you would like to develop with them. Other platforms we've got exercises already are Scratch, C# and JavaScript but feel free to choose something different as long as it's available for free.

Submission Guidelines

Submit your examples as pull-request to our exercises repository at

An exercise should be self-contained, ie contain a description of the task and an exemplary solution (both as README in GitHub Markdown format, language preferable in German, but English is fine). Full source has to be attached. Look at C# - Schleifen / Loops, Scratch - Fledermaus / Bat escape or micro:bit - Hot Wire for a reference.

You can develop your exercise for the platform of your choice. How ever, the required development tools and runtime should be available for free. Preferable your example can be used on most modern PC platforms such as Linux, MacOS and Windows. Keep in mind that the audience of your example isn't an IT professional, but a kid ;-)

By submitting a pull-request to acknowledge that your submitted code is subject to the GNU GPL v3.


At the end of each day our jury will reward extraordinary submissions with a brand new BBC micro:bit, which were generously sponsed by The Micro:bit Foundation.


Throught WeAreDevelopers it's also possible to pratice your coding skills, wether you're an experienced developer or one of our young coders. Finally we're dedicating entirely to a full day CoderDojo with some very special guests.
