Mandelbrot & Julia Set Maker

By Steve's Makerspace

You should watch the videos to understand how this works:

It takes a long time to generate an image, and the image is obviously very rough, but it works.

Steps:
1) Go to these sites and explore the Mandelbrot or Julia to find something you want to make, but don't zoom in very far because it will take too long for the machine to recreate something deep. Also note that max iterations is set automatically, and if you lower the iterations (as you will with my machine) you'll get a less detailed image:

2) Copy down the Left, Top, and Bottom numbers to the third decimal place (or more if you really want to go deeper). For a Julia set, also copy down the x and y numbers below the image.

3) On the machine, enter those numbers. For a negative number, every number block has to show as negative. In other words, -1.235 would be entered as -1 -2 -3 -5.

4) Select number of iterations. Expect 30 iterations to take 40 minutes to generate a full image! So only use this if you can leave your computer going and go do something else for a while. 60 iterations takes about an hour.

5) If doing a Julia set, enter the x (real) and y (imaginary) numbers all the way to the right of the machine, and TURN ON THE SWITCH on the poll in the Julia set section. If this switch is off it will generate Mandelbrot instead.

6) On the pole on the platform in the main section, press the brown button to clear memory, then turn on the machine.

7) Come back later to see your creation. Take a screen shot!
