Hi Guys.

I finished my first project!  Finally.  I got the idea from Mike =
Predeko's book for the LED clock.  But I couldn't find the right parts =
to put together the multiplexing for all the LED's, so I decided to work =
with what I have available and made a binary clock:  20 small 3mm LED's =
that show the hours, minutes, and seconds in bcd binary. =20

The design so far is simply a 9v battery, a 5v voltage regulator, a PIC =
16f877, a 32.768 kHz crystal + 2 22pf caps, resistors and LED's, and one =
resistor tied to MCLR.

The programming was fun.  Building and soldering the rat's nest out of =
wires on the back of the board wasn't.  (-:  (Took 3 weeks.)

I left it running for a test last night and it sucked all the juice out =
of my 9 volt battery in just a few hours. =20

Would someone give me hints as to how to figure out what the problem is =
why it is using so much power?

Thanks in advance.
Lindy
