I have researched many of the VFD clock threads out there and this is what came of it.
Ladyada for the ice clock write up. www.ladyada.net/make/icetube/index.html

Please note that I am not an electrical engineer, this is just a hobby, so apologies for any scary design :-)
Also if you like my work then please vote for me as I have entered the micro controller contest, Thank you.
Step 1: Board Design
Fritzing also supply a fabrication service which is well priced and very easy to use.
My design was based on the replaceable bulb style, so using separate plugin boards for the VFD bulbs. I thought this would be better than unsoldering stuff if there is a bulb failure.
The clock would use a real time clock ic and a temperature sensor.
There will be three buttons for menu operation.
I also found a nice little touch ic on HobbyTronics website, this will be used as a button to switch the clock mode between time, date and temperature.
I must admit that board design is great fun, it really brings out the OCD side of me ;-)
