3D Printed Mini Retro Computers


Use Adafruit HalloWing to make a mini Mac with images with sounds. 3D print a mini Mac for the speaker and display! Play the classic chime sounds from various Mac OS versions. A desktop toy that evokes nostalgia or prank device for co-workers? You decide!

The HalloWing PCB press fits into the face plate without screws and snap fits into the case. Speaker is housed in a back door with a working hinge. Parts 3D print without any supports!

No soldering necessary! HalloWing is pre-assembled and speaker is wired so it's plug-n-play! 3D print the case and snap fit everything together for easy assembly.

Circuit Python Code

Adafruit's CircuitPython is great for making slide show galleries that playback audio and display images. Use the capacitive touch pads on the HalloWing for input commands. You can rapidly update your code without having to compile and there's plenty of libraries, examples and support. Store plenty of images and audio assets on the built-in 8Mb SPI flash storage.

This project uses the Adafruit HalloWing M0 Express and a mini oval speaker. The speaker has a molex pico connector so it's plug-in-play!

Author Notes:

My first computer was an Apple Mac Performa 6300. I remember attempting to fix a Macintosh 128k in middle school because I told my teacher I owned an Apple computer. I was not able to get it running.

Phil Torrone (Mr. Ladyada) comes up with the best project ideas!
