If sighted folks knew how much companies charge for similar portable gadgetry aimed at blind people they'd be shocked.

Companies always quote R&amp;D costs of bringing a product to market for a very small market as the justification for charging $4000 for a portable Braille note-taker.  Open Source and the hacker community are slowly going to crack this monopoly.

If I could still see to solder I would be building one of these.
