Next, I decided to power the actual grids and plates to see the display light it's blue display elements. Here is a picture of the display I am using. It's a Futaba 6-BT-65ZK (Part Number 4230782). I know very little about Futaba part numbers, but I did find that most followed this format. I was unable to find a reference sheet on this actual display.
I attached 12 volts to each grid and tested each plat to see which elements lit up. After documenting the display connections, I arrived at this pin out for my display. As you can see, there are not many elements and it's geared towards a clock radio in a car.
Letters A - G apply to the segments in the 7-segment display characters. For more information on which element corresponds with which letter, see this Wikipedia image.
Next, I will be trying to figure out how to drive the display using a multiplexer circuit in conjunction with an Arduino. I'll keep you posted on what I discover along the way. :)

Really love your work.. Currently I am after DIY VFD drive so that Router at my CNC machine can be run at low speed without loosing Torque.. You are using Arduino but i don't think it would be capable to drive 2HP motor???

Hi Khalid,
Thanks for the comment. No, the Arduino would not be able to drive anything with a very high current. But, you could use techniques for driving higher current devices like a high current N-channel FET.
I looked at many of your blog entries and am very impressed with your work - especially your wood working skills - they are really great.
Keep up the good work and I'll keep reading your blogs - feel free to contact me anytime!
Mark~
