The system is now running with the new "Speak Shield"
beautifully produced by the Fritzing Fab
and mounted on an Arduino Uno.
Notice the MIDI connector on the left.
The stereo output connector on the right is temporary, until

I ordered six prototype PCBs. I need one for running the web site,
one for development,
and I could give away the other four,
of course together with the Arduino firmware to drive them.
If you are intereseted, contact me by email and make me an offer...
