Idea 003 - PCB Art of Every Mammal in BC

3 minute read

This post is part of the 100 project ideas project. #The100DayProject. I am looking for feedback. Comment below or DM me via social media Instagram, Twitter.

One Line Pitch

A series of PCB art badges, one for each mammal in BC. Each badge has a small sensor and some LEDs that relate to the mammal. Make a limited edition series of each mammal and show off the series at an art show.


Create a small PCB badge of every mammal in British Columbia. Doing this many iterations on PCBs should give me better practice with PCB Art design and allow me to learn a lot of the intricacies with PCB Art.

Everyone has their favorite animal, making one badge for each mammal ensures that everyone wants at least one of these badges.

There are ~130 mammals in BC. Many of the mammals in the same families look very similar, such as the plethora of rodents. I suspect that I can reduce this number to the major family instead of every rodent in the group. It would be worthwhile to find a way to reduce this list if possible. Just the most recognizable animals would be 15.

To help reduce the amount of design effort that would be required. I would use a mixture of SVGs from “the noun project” and outlines of photos to make the PCB outlines. Looking for “Badges” “patches”, “enabled pins”, “Stickers” would also be a source of inspiration.

In most cases it would be just the head. With LEDs for the eyes or teeth. One sided board, for simplicity of board design. SAO connector as well as a battery clip for the back. If required the programming pins should be in the same format for every badge. Because the SAO uses 3.3v this limits the kind of electronics that I can use. Reverse leds that use the fiberglass of the badge as a diffuser. Think eyes 👀

If it needs brains then use a small cheap processor like the attiny85 ($0.83 each)

Prior art

Primary inspiration came from this youtuber Michael Alm where he water painted ~141 pictures of mammals over a 2 year period. The video is about him making 141 frames for the art show but near the end he talks about this project.


Other inspiration came from existing PCB BadgeLife badges.

Art lovers, Electrons enthoists, anyone who loves animals.


Rather than the attiny, I would choose one of the chinese chips like WCH(Jiangsu Qin Heng) CH32V203C8T6 ($0.55) lots more capability. 64KB Flash, RISC-V 20KB RAM, 144MHz, 16 TouchKeys, 8 UART, Analog, and digitial pins.
