[sdiy] An alternative for hearing, Braille and phase shifting DC.

[Samppa Tolvanen]

Hi,

I´m hearing impaired. I simply can´t hear. Do You have any alternative
methods for me to qualify the tone? Like I have a really good
perception of the colors and luminosity and stuff?

Anyway - I´ve found that Braille keyboards are pretty nice alternative
for  the 104 keys on normal Keyboard.

And what is wrong? I shorted DC blocking caps on my small stone and
threw +1VDC there - even if I manipulated phase shift control It just
put out +1VDC.
