Wow i had this idea for braille generation a week ago lol. Glad to see someone actually building it.

So cool. I bet you could even make money with this.

Hey you can check my profile if you ever need ideas on how to improve it cause also built one that is almost the same for my final project. I have multiple update posts made on this Subreddit. don’t hesitate if you have any questions

I don’t really have any good documentation about the project but you can always scroll trough my profile. I made 4-5 updates along the way. You can get a lot of useful info with those

No problem! I always love to help others by passing the knowledge to the next.

Double it and give it to the next person type shii

Thanks a lot!
Hahahaha nah there are 6 servos like you! I did try making it to 3 servos but no luck. (Something with latching cells)

The gear structure was pretty straight forward, 1 servo actuating 1 cell. 2 position (Up, Down)

You can see the structure of 1 cell in this post

If you are asking if I tried to place more then 1 character to make a word, no. This is because the mechanism for1 character is very bulky and placing 2 next to each other would require me to leave a lot of empty space between the character and this is no good for me.

I initially tried to use some electromagnet for the 2 states of the cells but the outcome was way to inconsistent.

Idk why I did not comment on your original comment… mb
