I am looking for the following...( google produced nothing)
an LED or LCD minute clock ( just 2 digits) 4-6 inches in height and is high
visibility, prefer AC power.

Perhaps a link to a kit or schematic so that I can build it myself.

Thanks for any info.

I built a schematic for this. Take a look at

http://home.comcast.net/~rcmonsen

I have not breadboarded it, but simulation seems to work fine. Make sure the
7 segment display driver can drive your big LEDs.

Well, thank you !

Just out of curiosity. What would you estimate this to cost?
What if you built it and sent it to me?
Just curious.
Thanks again

The total parts cost would be dominated by the 5" displays, which'll run you
about $40 each (ouch). The transformer is about $10. The microcontroller,
shift registers, and assorted power mosfets is about $20. So, you are
looking at about $110 in parts. The case will be more, depending on how
fancy you want it to look.

Its too bad I didn't buy that large digit (4") 7 segment display A/C alarm
clock at the yard sale yesterday for 50 cents; its possible though that your
application will require brighter segments. The ones on digikey (see link
below) should be really bright.

Actually, I just found some cheaper displays:

$13 for 5" high 7 segment red displays. Much cheaper, and they look about
the same from the specs.
