Great work!

Hmm.? There was audio when I viewed it.
BTW, nice job, Doug.
Thanks,

Excellent Doug! ?It might get even more guys

I can¡¯t hear any audio on my iPhone for some
reason.

I have completed the construction
of another Si5351 FS4 replacement using the
Adafruit I2C rotary encoder with a voice
option to say the selected frequency for the
sight impaired. This required considerable
refactoring of the sketch. It uses the
"talkie" LPC voice using the PWM output of the
Nano, a simple filter circuit, and an LM386
amplifier module driving a small internal
speaker. The voice is robotic but very
understandable. I edited the over one
thousand-word vocabulary library to include
just the words needed to say the frequency.
Since everything is on the I2C bus, it
simplifies wiring and the encoder just works.
The voice output is optional both in the
construction and in the sketch. I will be
coming out with a complete documentation
package in the coming weeks, including the
sketch and FS4 voice library, which I will add
to the Drake files section. The rotary encoder
and LCD libraries are available in the Arduino
IDE. I highly recommend using the I2C rotary
encoder, which solves the problem of bad
encoders using the Nano GPIO and current
rotary library.
Here is a short video clip showing it in
operation -?
