I still shop Radio Shack, and I remember when Radio Shack was staffed by Ham Radio enthusiasts, electronics buffs, and was a coveted after school/summer job to get for some of the high school Ham Radio/Electronics geeks.
Most of my stuff now comes from DigiKey.

Russell 27 wrote:I just used WINAVRs programmers notepad to compile. If there were no errors in my code, everything seemed to compile. Of NOTE: I do not have the Cygwin/perl files installed as you had noted in your post, so consequently when I compile through programmers notepad I get a message in the output box " no perl found", something like that, files do compile nonetheless.

Sounds nice. I'm open to code contributions.
I've always taken it for granted that these old VFD tubes were designed for a sine-wave-AC filament drive. In another thread, I found that the brightness gradient completely disappears when driving the IV-18 to specifications, but using +5 volts DC on the filament. I also could not find a reference to AC (переменный ток) in the IV-18 tube specifications, but I am not able to read Russian.
