Here is A, B, and C in Braille:
…and here the rest of the alphabet:
You can connect them to your existing binary system by placing the binary system’s object next to a picture of the letter the cell represents. You can find animal alphabets, etc. on the internet to assign an image to each letter. Do this either on a 26 loci journey or just use the alphabet itself as a peg system.
First cell shown above:
Say your animal for A is “alligator” and your major code for TS (100 000) is “toes”. You can imagine 10 tiny alligators biting into each one of your toes. You don’t have to read top to bottom but reading bottom up for RS instead of TS feels a bit upside down to me (personal preference though).
Another one further down the alphabet:
Say your animal for T is a “tiger” and your major code for JM (011 110) is “gem”. You can think of a Tiger’s eye (https://en.wikipedia.org/wiki/Tiger’s_eye)
For those of you that don’t have a binary system yet but images for 00…99, here’s how you read the binary as decimal:
Consider the braille cell: two columns of three dots each. The left will give you the tenth digit and the right will give you the unit digit. If a dot is raised, its value is counted for the column total. The above examples for A, B, and C are: 10, 30, and 11, respectively.
For the tiger example above, it’s 2 + 4 = 6 in the first column and 1 + 2 = 3 in the second column; so 63 for JM which could then be “gem”, “gym”, “Jim”, etc.
Where to use it (other than reading braille of course):
Say you memorized the periodic table but you have trouble with the symbols for the elements. You can just store A (“toes”) and U (“lyre”) next whatever represents gold in your memory palace. Say Goldfinger (James Bond villain) using his toes to play the lyre, maybe even let him play ABBA’s Money, Money, Money… detail of the image is personal preference of course.
This is different from just using a word with A and another one with U, because you are using only images that exist in your 00…99 system, which you are probably very familiar with. Toes is TS (100 000) and you know those got bit by “A” (alligators) and Lyre is LR (101 001) which you got somehow tied to a “U” (let’s say: unicorn).
If you’re just starting out learning Japanese you can use it to reference Hiragana instead of the Latin alphabet. It works the same way as described above, only that the braille cells represent a different set of characters. Have a took here:
