[GreenKeys] TTY-Connect PCB Wanted

[Steve Ripper]

Gil:

Thank you for the information regarding the TTY Connect PCB and potential
changes to the original design. I would be interested in purchasing a
minimum of 3 boards of the existing PCB design. I am quite sure that Ronan
who resides in Ireland would be interested in 1 or perhaps more. I sure
others would be interested as well. Please let us know what it will take for
you make another run of the TTY-Connect PCB. I have my Mouser
bill-of-materials ready to go!

Regards,

Hey Steve:

Sheesh, don't go and re-create it in Eagle -- I did the original
schematic/board in Eagle.  Can't release it, as the library parts are
all company-owned.

Maybe I should just get another batch of the current boards made, as
there has been quite a bit of interest.

I've been meaning to update the design, but just have not yet found the
time.  It's been a a pretty crazy year for me between work and family. 
I have been tweaking the tty-connect firmware off and on all year, but
have not finished the next release.

As for a new tty-connect board, I was planning to try a current-source
design for the high-voltage loops, to maybe cut down the standby power
and heat dissipation.  Anyone have a current-source design they have
used for tty?  I would only change the 60-mil HV loops, as the LV loop
is fine as-is.  I was also considering adding more 1/4" jacks to the HV
loops.

Another thing I want to add are drivers and connections for motor
relays.  I have also been considering adding an ethernet port, but I
don't write pc application code, so I'm not sure how useful it would be
to have a tty-connect with a tcp-ip socket port, if there is no app to
connect to it.  Anyone write that sort of code?

The primary purpose of tty-connect is to provide an ascii-only computer
interface, to get away from the special hardware and apps to drive
baudot out of a pc serial port (this gets harder each year, although it
is done quite well in heavymetal and rtty-art).  Of course, you can
leave the PIC off of tty-connect and jumper the opto-isolated 232
section to a tty loop section -- then it becomes an interface board for
an app like heavymetal.

But if the baudot-to-ascii-converting PIC is installed, a logical
extension of tty-connect's ascii serial interface is an ascii socket
connection on an ethernet port -- however, it is all a matter of network
applications, which don't exist, and I can't write.

thanks,

gil
