Just for fun, here's another output method. I found a "hobby servo"
intended for large model aircraft or boats, that swings through 180 degrees
in under a second. It has "holding torque" so strong it's hard to force a
pointer mounted on the servo to move when it's stopped.
So I ran this with a microcontroller and made a meter reader out of it. Has
a tactile dial with moving pointer.
Again, because Smith-Kettlewell had no ability to make more than a
prototype, that's all I could do.
But having a real tactile moving pointer meter was a ball. Yes it worked
fine across a VSWR meter.
Lest you think the servo was expensive, it cost about $13.00. and outside of
the braille dial and custom pointer, I doubt there were over $30.00 in
parts in the project. But to build themin small quantities would be pretty
high cost.
