Submitting your physical build!

Finished building your project? Awesome! Here's everything you need to do:


1. Update your GitHub repo

Once you've built your project, make sure your GitHub repository is up to date! You should add in the following:

  • Any files you've updated since (3D printed parts, schematics, firmware, etc)
  • A picture of your project in the README.md

2. Record a video demo!

Next, record a quick 1-minute video of what your project is, what it does, and how it works! It doesn't need to be super edited or professional - a recording from your phone works fine

Post it on YouTube afterwards - it can be unlisted if you'd like.

3. Share your project online

Share your project online! Reddit is heavily preferred, but Printables is also fine if your project has 3D printed parts with it too.

An example post is @Cyao's Icepi Zero - he's a 17-year old Hack Clubber from France!

We would also REALLY appreciate it if you could plug Hack Club!!! No pressure though - just helps to spread the word :)

4. Make a magazine page!

We're making a Highway to Undercity magazine! Vol 1 has already been printed, but we're making a Vol 2 that'll be bigger and better. In the past two weeks, Vol 1 has been given out to Michael Reeves, Strange Parts, lots of large companies, and more - we're planning on going even bigger than that!

What's new with Vol 2?

  • You must include at least 1 picture of the physically built project
  • We're including Undercity moments too!

Got questions? Ping @acon on slack!
