When I was young I always wondered what's inside these ICs and how do they actually work. I disassembled a lot of appliances but not having much of a clue.

Then I stopped for many years, became occupied with computers...

Interesting to see the pricing when looking for this IC, if I would charge such prices on my ebay...

Not bad for a first time project? Is it?

My guess is 6:42pm.
Brownout is correct, That led on the left is for pm and the one above it is for am.

I've attached a quick drawing of how I hooked it up, for more info see:

The circuit in the pdf can be a bit confusing (it was for me at least).

Obviously, you'll need to adjust the resistor values for the displays according to the voltage you are using etc.
