Re: braille keyboard?

Can you go into more detail about the "translation board"?

Have a great day,
Alex

you'd need to get a little more advanced and see which keys were 
pressed
at what times, then translate them to the print version and send 
them out.

Hi all,
This has been on my mind off and on for years: I would like to 
make a
Braille keyboard. I am realistic enough to know that it will 
probably
never happen (I could not pay for all the parts), but I want to 
know
about the programming end of things. How would I go about this? 
I assume
a microcontroller with a pin for each key. The controller has a 
sort of
"database" where certain pins mean send certain keyboard 
messages, and
send nothing as long as any key is pressed (except control 
keys).  Am I
way off the mark? I imagine nine keys (six like usual plus 
space,
backspace, and enter) as well as control, shift, applications, 
escape, a
key for JAWS or other screen readers to use (mimics Insert with 
numlock
off), and Windows, and maybe a row of function keys. Is 
something like
this possible? I know that some devices like this exist, but 
they are
extremely expensive and I do not know if they have all the 
modifier keys

necessary for full computer control.



Have a great day,
Alex
