Free Downloadable Science Brushes for Adobe Illustrator

I’ve used Adobe Illustrator for years, but I didn’t use brushes very much. This weekend I watch the course “Creating Custom Brushes”. My library gives me free access to through their website; yours might too so check it out.

In my zeal, I created a few science-themed custom pattern brushes. Two of them are created from real experimental data. You can see them drawn onto paths below. If you like them, you can download the .ai files through my Creative Cloud presence at the following link:

If you use the files, please satisfy my curiosity, and either comment here or mention my twitter handle @Vironevaeh. I hope they are as fun to use as they were to make!

What are the paths? (counting from the top)

  1. The top path is loosely based on the body-centered cubic crystal (BCC) structure. A real BCC crystal has atoms in the middle of every cube, rather than every other. It also extends in all three dimensions. Iron and chromium form BCC crystals.
  2. This path is real experimental data from coupled Colpitts oscillators. A Colpitts oscillator is a simple electronic oscillator made from resistors, inductors, capacitors, and a transistor. Without coupling, the oscillations are simpler; the interactions cause them to make this interesting pattern.
  3. This path is the “skeletal formula” for a random organic molecule. Next time I will make some polymers, but this one was for play.
  4. A cubic molecule.
  5. More real experimental data, this time from an electrochemical experiment. This is the current produced from the dissolution of nickel oxide in acid. Here, six oscillators are locked in a pattern. (Note that this path has a lot of anchors so it’s a little slow. Maybe this one was more for my fun.)
