Hi all
I am after a circuit diagram for a talking clock.
Most apreciated if anyone can help.

Specify, how often do you want it to talk, or at a push of a button,
or what?
Go to:

and then use the numeric outputs to locate a memory block in an
EPROM or several, add a counter for making it talk, and then record
in your speech and burn the EPROMs. Run the 8 data lines of the EPROM
to an R-2R ladder DAC, and then to an amp, like an LM386 and speaker.

If you want to be fancy you could make the numbers all separate memories
and cue them with a counter chain doing the talking-addressing using
the digit numerics as positioners in EPROM address space. If you wanted
to be fancy you could use an SPO256 and feed it numeric codes using
an EPROM and counter string, but the EPROMs already there, so why
waste one of them on such a trivial task. If you like the robotic
sound, you could record the SPO256 into the EPROM.
You can play any 8 bit mono .wav file that way by burning it into an
EPROM. The header is a tiny blip on the start of a wav file, that can
be edited off with CoolEdit or such, but it works without doing that.
