3D Printed Miniature

In this tutorial, you'll learn how to build and assemble a mini replica of the PET commodore. This isn't necessarily useful or an actual computer, it's just a cool prop.  You will however, hopefully gain some experience, learn something new and have fun :-)

From Wikipedia:

The Commodore PET (Personal Electronic Transactor) is a line of home/personal computers produced starting in 1977 by Commodore International. A top-seller in the Canadian and United States educational markets, it was Commodore's first full-featured computer, and formed the basis for their entire 8-bit product line, including the Commodore 64. The first model, which was named the PET 2001, was the first personal computer ever made available to retail consumers.

Charlieplexed LED Matrix

There's 144 LEDs in the Adafruit 16x9 charlieplexed matrix. It's a classic LED matrix look that uses the IS31FL3731 chipset and can PWM each individual LED in a 16x9 grid so you can have beautiful LED lighting effects.

Prerequisite Guides

We suggest walking through the following guides to get a better understanding of the components and Arduino IDE. We also have great tutorials on learning how to solder.


All of the components used in this project are listed below and in the right hand sidebar.
