Bruce talks about refreshable Braille

[HedgehogStudios1]

refreshable braille cells use piezoelectric crystals. When a voltage is applied, the crystal deforms and it pushes a series of levers and moving parts to push up the pins. That is why they are so expensive.

I find that I get more done with speach, I can only read Brl for so long

I see that the braille display you're using is in fact a BrailleNote PDA, I assume once you've bought your books as you discuss in this video, you would scan them into your computer using something like Kurzweil 1000 or OpenBook and then you would transfer them to your BrailleNote and read them on the go, right?
