Ah. Real-world economics scotches another clever techno solution :(

they have. however, thermoform paper is actually more expensive than standard
paper stock. also, the "thermo" brailler (embosser) isn't cheap either.
now, there are small form factor varieties that will work on 3x5 sized sheets.
those run about $500 and are good for labeling prescription bottles,

Bond paper is traditional. Haven't they figured out a way to emboss thin sheets
of polymer yet?

that I am not sure of. these embossers are used at places like the American
Printing House for the Blind. considering how much material is printed in
braille monthly, their maintenance is a bit expensive. these are not your

Hmm, sounds like an entrepreneurial opportunity making a cheaper unit. What's
the input? Unicode?

Considering you have found out how cheap the electronics are I expect I

sort of hard to find power failur
ok. considering the design, I had originally thought it was from the late 19th
century. my bad!.
still, the thing was definitely over engineered. I can't honestly say the same
thing about the newer, lighter plastic models. what I find disturbing is this:
the newer plastic manual brailler is prone
such a device, possibly redesigned in modern way+electronic that would
automatically control it and you get braille tty.

It should probably be an TERM=thumb then in an ideal world..

oh yeah. thermoform paper. the problem is that any heat tended to permanently
deform it. it did produce some nice sharp braille.
I am not material expert but i think it is possible to make thermoform
"paper" that could be thermoformed multiple times. once when printing then
ironing out. Even i

the other thing which works well for storing long term braille (like an index
card) is the plastic backing out of bacon packages. that stuff is heavy enough

yes. the problem with small market. Such device should not be expensive if

the problem is that they are so expensive. in fact, anything that is marketed
to the blind gets some cost boost because the manufacturers claim its a niche
market (I don't call 26 million people a niche market). there is also the
problem that these same manufacturers use government contracting as a
