I do stuff like that too. I always like to use an I2C connected LCD
display while developing code on any micro processor project. I might take
the actual LCD off at the end but I always leave the signal pins in place.
I might need to debug the device again some time and then I can find

Is there a term similar to "eye candy" for geeks?
Many years ago, I
I used to work at a place that used a lot of those LED time displays that
were hooked up to IRIG. Why were they there? Because everyone hates to
toss out nice working equipment. The displays were bought ages ago and
still work just fine. Many of those racks you see were assembled 15 or

I can
Two reasons that come to mind are:
Displaying distributed time to distant sites from some master.
Readability at a distance.
