digital clock re wire

[jonnythesurfer]

Hi there. For an A-level project we have to create a clock. I have designed a digital clock where I create the 7 segment displays. I don't have to create the electronic mechanism to do this but would like to create a working clock. I was thinking of buying a very cheap digital clock and removing the LCD screen re-wiring it and inserting my 7-segment displays, made using LEDs. I guess this would be possible and if so is it easy and how is it done? (any wiring diagrams?) if not is there a simple way of creating the mechanism needed which I can do at school for as little money as possible?

Any help would be much appreciated thanks

It would be quite difficult to change from LCD to LED - far easier to just build a microcontroller powered clock from scratch.

oh really? which would be more expensive? what is the best way to build on from scratch?

Building from scratch with a micro-controller would probably be cheapest and easiest.

Otherwise you have to demultiplex the AC drive to the old LCD displays.

Ok thanks I will look into it...

what micro-controller would you recommend? any that are easily programmed? and set up for a beginner like me? I have only ever used simple picaxe project board at school which could only do on figure. any simple diagrams?

An entire PIC clock project is in my Dragonfly manual on my site.
