Busy Light (Raspberry Pi Zero)

This is the very first model I’ve ever designed, and while I know it’s not perfect, it gets the job done. 😉

You can find the full story, including all the details about the software, in my blog.

The busy light uses a Raspberry Pi Zero WH and Waveshare Full True Color RGB LED HAT.

To assemble the case, you’ll need the following:

• 4x M3 Ruthex
• 4x M3x16 screws (e.g. these)
• 8x 6x2mm magnets (e.g. these)
• superglue
• hot glue (optional)

“Issues”

Due to the bend of the USB cable when attached inside the case, the design ended up being slightly wider. The recess for the USB port also isn’t perfect. I added a support behind it and initially planned to glue the cable in place. However, since I don’t own a hot glue gun, I tried superglue instead - but it kept coming loose. In the end, I resorted to zip ties to force everything into place. For the next revision, I plan to add more supports on all sides to secure the cable better.

Another issue is that the LED hat sits a bit too close to the lid. This results in the light being distributed more in the center rather than evenly across the sides. A simple fix would be to increase the distance between the LED hat and the lid or shrink the case slightly to eliminate this issue altogether.
