[NFB-Braille-Discussion] Electric braillers

[Jen]

Thanks for your excellent explanation of why the electric Perkins brailler
would be louder. That also explains why embossers are so loud! With
embossers, there's an emboss head hiding under the papper and, when it
embosses, you can feel the had move back and forth.

The mechanism for the electric brailler reminds me of the mechanism for a
computer keyboard. Every key has a switch under it that tells the computer
to output whatever key you press.

Good luck with your electric brailler!

Jen

Hi,


First, just do a Google search for "electric perkins brailler," and you will
find the electric brailler I plan to buy.


Second, I got an e-mail from Perkins products, and the person said the
electric perkins brailler will emboss just fine on thermoform and plastic
label sheets.


Why is the electric perkins louder? The electric perkins brailler is louder
because it uses solenoids, coils of wire that act as magnets when
electricity is applied. It uses the solenoids to strike or hammer the
styluses into the paper, and it hammers it against a metal die in the size
and shape of a braille cell into a dot-shaped indent, and that is another
reason it is louder. A solenoid or solenoids are striking metal styluses
hard and very fast against a metal die or plate, so metal hitting hard
against metal quickly will make lots of noise.  very fast. So when you press
keys on the electric brailler, your key presses activate electric circuits
that send a message to the solenoids in the perkins brailler carriage or
emboss head, and then your desired dot combination is hammered into the
paper, probably in one-tenth or maybe one-twentieth of a second and,
immediately afterwards, the carriage advances to the next braille cell, so
you can see why the electric perkins brailler would let you write much
faster? Because you just have to press the keys very lightly, just like you
do with a computer keyboard or when writing with a braille display, so you
can write very fast because the solenoids and other components or electrical
parts are doing the hard "punch the paper" work for you, letting you
therefore type very fast while still getting good dot quality.
