Oops, sorry, the SmartSockets are 5v-serial (not RS232 volt levels) controlled, not I2C bus controlled. which is even easier to drive than I2C.
You can find them here - http://www.tayloredge.com/storefront/1386_B7971SmartSocket/index.html
They are normally used to drive the large B7971 alphanumeric 14-segment nixie tubes, but you can easily drive any 14-segment starburst display with them. Quite a few people have used them to run LED or VFD displays.. http://youtube.com/results?search_query=smartsockets&search=Search
If you arent going to use the big B7971 tubes (about $60 each, so maybe not affordable), then you can just leave out the HV transistors and resistors off the smartsockets boards when driving low volt displays, or just use the smart-sockets micro (buy programmed, or download the code and program your own, its free) and make your own board.
The Micros are cheap and mean you can drive as any displays as you like from your controller with a single daisy-chained serial line.. more info and example of use of alternative displays here. http://www.tayloredge.com/reference/Circuits/1386SmartSocket/index.html
If you just want numeric display capability without alphanumerics, then the Smart-Nixies (as opposed to the Smart-Sockets) are the I2C driven model, and can run high voltage numeric nixies, or be run in "Numitron" (7-Segment) mode to drive any ordinary 7-seg displays from an I2C bus and are quite cheap - http://www.tayloredge.com/storefront/SmartNixie/index.html _________________ Great minds discuss ideas.
