I use the Major System for my 3 digit system (images from 000-999), and the Shadow System for cards (which is a 2 card system). The SS is based off phonetics from the Major System for the most part. For binary, I used a 4-3-3 which also pulls from my images for numbers and cards, plus I had to create some unique images as there are some phonetics that occur in my binary system that don’t in numbers or cards. In total I need 1381 images (had to create 3 unique images for dates as well).
Here is a link to a post I made in 2020 with a link to a spreadsheet I made for my system. There are links to the original SS and Binary posts there as well, both authored and created by @LociInTheSky
