TIC & SpeakJet Demo Video ...

[Walt Perko]

Hi,  

This is a basic demo showing the stepper motor moving from the commands sent from my Altair 8800c computer to the Pololu TIC T-500 Stepper Motor Controller Module and the NEMA 17 Stepper Motor:

The little box I showed in the ZOOM is what I'm currently using for the SpeakJet to talk and sing.  

I'm trying to wrangle out an S-100 board that would essentially be 1/2 of Patrick's 88-2SIOR1 board using just the TTL level I/O to the SpeakJet that would also include an  audio amplifier with hopefully a speaker on the board but also a Volume Control, Line OUT and a Speaker OUT jack near the top of the board for external control.
