SeeingEyeduino - Working Braille Finger Pad : Blog #3

Hi everyone,

 

For my 3rd blog I will be showing my working braille finger pad. There will be more to the final setup but this shows how well it works. I ended out getting 6 miniature actuators to create the braille pins. It goes back to my original idea of using electromagnets. In this demo I used an Arduino Uno which will be changed out for the one supplied in the kit. As a note; I won't do an unboxing of the kit as other competitors will be doing this and I didn't want to repeat the blogs.

 

Below are pictures of the Braille finger pad:

The video attached is of the working braille pad. I will upload the code later as I would like to see who can figure out what the braille pad is spelling out. Please comment if you know!!

While making the Braille Pad I learned a lot about reading Braille. The average Braille reading speed is 125 words/ min and speeds have been recorded up to 200 words/min. So to put this into an easier way to understand (For myself anyway) that would be roughly 10 letters per second or my video cut down to 1 second since there were 10 letters. So my Braille pad has to be sped up a lot to reach the 125 WPM. This won't be the case as Braille has 2 levels, the higher level uses some abbreviations for common words to make reading faster. I will be researching this as I want to learn more about Braille.

 

Thank you for reading and watching my blog

    Hi Dale, Nicely Done! Those solenoids remind me of the ones that get used in door bells. John

    That is AWESOME! I love it! Too bad about the smaller actuators. This certainly works as a proof of concept. Further development could use remote actuators and cables or strings to make the finger pad…

    It’s ‘Hello World’ ;-) I’m new to the Braille concept and read out the answer from your blog which followed this update Seeing Eyeduino - Blog #4 Motors and more Apologies for being late!

    Ahh - perfect then. They looked like they were the size of a thick deck of cards in the photo.

    Hi James,

     

    Thank you for the comment. The actuators are the perfect size for the tip of your index finger.

    That is AWESOME!

    I love it! Too bad about the smaller actuators. This certainly works as a proof of concept. Further development could use remote actuators and cables or strings to make the finger pad actually finger sized.

    I’m getting reminded of my project which I did during my bachelors where the solenoid was supposed to press the perfume bottle to let out the perfume.
