I scored some huge two-character VFDs from an elevator panel refit, along with several smaller 16-character ones that accept serial input at 600bps. The IV-4/IV-17 ones are a good size and still affordable. Noritake occasionally gives away some nice VFD doc matrix displays, too. > One of the important points in using them, as you already noted is to look > good, they need to have accurate spacing, so it sort of rules out individual > LED’s - which are really cheap. You can build it up out of individual alphanumeric LED displays, which are available in a bunch of large sizes (like the Evil Mad Science 5 letter clock). I'm also working on an ongoing project to use an old monoscope tube as a character generator to display nicely formed characters on a small CRT. This could be the basis for a 4/5/6LW project, including some fun effects like stretching letters vertically or horizontally, and moving them around. I'm on about the sixth redesign (LT1172 switching regulator driving a CCFL inverter with a voltage doubler) of the monoscope power supply at this point. > I like the idea of a scrolling clock or FLW – these days micros are not > expensive.

Some of the PJRC boards have PLENTY of memory and CPU horsepower, and they're small, cheap, and can be used with the Arduino toolset. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
