Might be worth a look ar www.siliconchip.com.au. They published a light
box design from a fellow Tasmanian. He included a PIC timer pcb and
code with the article. I'm sure pcb pattern and code are downloadable
from that site. Cant quite remember which month it was published but
I'm sure it was late in 2007. Sing out if you cant find it. I have the
magazine here somewhere.
