Don’t make something you don’t use yourself.

Know who you’re making it for.

Know what you want out of it.

Make projects, not platforms.

Good hardware, good software, good explanation and generous users make a great project.

Document what you make.

Change is painful, expect resistance, and conspiracy theories.

Including people is hard but necessary.

If you’re not prepared for someone else to adapt/improve/clone/trash your work, don’t share it online.

You can’t run a startup part-time.

Don’t let the fact that you don’t know what you’re doing stop you.
