Big 6 Digits Seven Segment Digital Clock

This is a my second Digital Clock project.Which is having 5.5" height 6 digits seven segments.

Working with PIC16F876A microcontroller 
Power : 12V DC / Ampere : 1.2A Max 
Time Display : Hours / Minutes / Seconds  

Length : 24 inch
Height :  7inch

I will add a fully completed clock picture with aluminium frame which I made. :-)

Step 1: Find a parts for schematic diagram

Check the attached circuit diagram for part list.

Common anode 7Segments - 6Pcs
PIC16F876A - 1
ULN2803 for Segment outputs driver stage.

2SA1680 and 2SC2785 for Segment Common Anode outputs.

check the pin outs for 7 Segment and finished circuit board.

Nice job! I'm interested in building your project to keep track of our triathlon times. How can I add tenths of a second to this?

Hye.. currently i'm doing digital alarm clock with 5 time set. but it seem really complicated for the circuit. i need to use many decoder, latch and buffer. i dont know how to make it simple. before this i'm using Easy68k but now i want to try using PIC. can anyone help about the schematic first.. here is some document that can make u understand what i mean..

[chiren1]

where is the hex file

Do you have a modified setup for just hours and minutes without the seconds panels?

where is the hex file??

[prash_thil]

nice one user:slwthr
but i recommend a clean desk atleast when taking the picture :P
plus(+)
scan the diagrams will ya :P

possible to read though!

i made it and worked fine! no faults at all

[itsjustdoc]

Bah! Clean desks! Who needs 'em?!

[aasif.faiz]

Haha PP Desilva , i'd cut one of my ears off if u actually made it :P, BTW Nice Instructable Harith

[slwthr]

hahah...I will make it as a sexy table as soon as possible :D

[shifna iqbal]

waoo...dis s unblvbl haryy...awsm...keep it up boy...:)

[slwthr]

hey thanx a lot shif! :-)

[prash_thil]

haryy?? O.o
