I don't think this makes for a good featural script the way i've done it (as someone who doesn't know Braille), but i had a dream about this last night so i decided to work it out anyway. Braille letter numbers are in parentheses.
Vertical position indicates PoA. Horizontal position is voicing.
⠁/k/ (1)
⠈/g/ (4)
⠂/t/ (2)
⠐/d/ (5)
⠄/p/ (3)
⠠/b/ (6)
⡀/h/ (7)
Dot 7 (h) indicates a fricative
⡂/s/ (27)
⡐/z/ (57)
⡄/f/ (37)
⡠/v/ (67)
And that's as far as i got in my dream. But i can take it further now that i'm awake.
Add dot 7 to 1 and 4 to make
⡁/x/ (17)
⡈/ɣ/ (47)
Modify ⡂/s/ and ⡐/z/ by adding dots 1 and 3 to move it further forward or backward, making
⡃/ʃ/ (127)
⡆/θ/ (237)
⡑/ʒ/ (157)
⡔/ð/ (357)
And as i try to find a way to turn ⡄/f/ and ⡠/v/ into /ɸ β/ i'm already running out of combinations. Braille's 255 letters are enough for one language, but without a language in mind i found myself trying to represent the IPA and that's a bit much while trying to keep it featural.
I could try just the sounds in my accent's English.
⠁/k/ (1)
⠈/g/ (4)
⠂/t/ (2)
⠐/d/ (5)
⠄/p/ (3)
⠠/b/ (6)
⡀/h/ (7)
⡂/s/ (27)
⡐/z/ (57)
⡄/f/ (37)
⡠/v/ (67)
⡃/ʃ/ (127)
⡆/θ/ (237)
⡑/ʒ/ (157)
⡔/ð/ (357)
And now, the consonants that don't fit nicely into my chart of voice and fricatives/plosives for 3-ish places of articulation. I want to reserve dot 8 for vowels, so i'll use 1 (k) and 4 (g) as modifiers.
I'll do the nasals next. They're all voiced, so dot 1 (k) will be the modifier i use.
⠉/ŋ/
⠑/n/
⠡/m/
Then /ɹ ɫ/ can map to patterns 2 & 3 with dot 4 (g) as a modifier. This mapping isn't as nice as the nasals, partly because pattern 14 is taken and i have to shift them forward from their places of articulation.
⠊/ɫ/ (24)
⠌/ɹ/ (34)
/j w/ next, and if i use dots 1 and 4 as modifiers i can do /t͡ʃ d͡ʒ/ at the same time.
⠋/t͡ʃ/ (124)
⠙/d͡ʒ/ (145)
⠍/j/ (134)
⠩/w/ (146)
That just leaves /Ɂ/, the glottal stop.
⡉/Ɂ/ (147)
I'm inverting the fricative marker here, but i don't see a better way to do this except maybe using pattern 123 ⠇, all the basic unvoiced plosives.
And now, vowels. All of these will include dot 8 ⢀ to differentiate them from the consonants. I'll start with the ones that are easy to map on the front-back axis.
⢁/i/ (18)
⢂/ɪ/ (28)
⢄/u/ (38)
⢈/a~ɑ/ (48)
⢐/ə/ (58)
⢠/ɔ/ (68)
And modify these with one another to get more vowels and some diphthongs.
⢆/ʊ/ (238)
⢒/ε/ (258)
⢰/ʌ/ (568)
⢊/æ/ (248)
⢉/eɪ/ (148)
⢤/oʊ/ (368)
Next, i'll combine these where i can to get the rest of the diphthongs, and rhotic vowels too. I'm using the symbol /ɹ/ but i think /˞/ is also appropriate.
⢋/aɪ/ (1248)
⢎/aʊ/ (2348)
⢢/ɔɪ/ (268)
⣂/ɪɹ/ (278)
⣒/εɹ/ (2578)
⣆/ʊɹ/ (2378)
⣠/ɔɹ/ (678)
⢌/ɑɹ/ (348)
⢜/əɹ/ (3458)
And i think that's all the sounds my accent uses, barring the occasional /x/ or /ɕ/ in names. And i didn't distinguish nasal vowels (which i think are rarely if ever phonemic). Now, a short sample text. Spaces preserved for legibility.

Now, is this a good script⸮ I don't know. I don't think it's good for reading visually. The letters are too similar and too close together. But maybe it's fine for reading manually. I doubt it's better than existing Braille systems because people have put a lot more time and effort into making them good than the two hours or so i've spent on this (i assume), but maybe i'm wrong there. Without knowing Braille i really can't tell.
But here it is. Braille as a featural script. This sure was one way to spend a morning.
This is a game called chants of the sennaar and in order to progress in this game you must start to understand the writing system through context and the puzzles presented. I think this works super well and was much easier than I expected.
I kinda like the way this looks as it makes the script predictable but I still feel like it could really be improved
These two are pretty bad in my opinion as I can't really tell where the dots are meant to be and it looks very overcomplicated.
This is the original font and I believe it can be easily written (unfortunately my artistic skill is pretty low).
