As the B7971’s are so expensive these days, perhaps we should look for really large VFD’s. Or LED matrices.
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. I like the idea of a scrolling clock or FLW – these days micros are not expensive. So it should not be too difficult to do a large scrolling clock then the issue of four, five, six , sever or more scrolling words is not an issue, especially if the matrices can be banked together. ---------------------------- Jack Buechler T: +44 207 0437809 M: +44 7946002001 S: jack_buechler From: Morris Odell Reply-To: "[email protected]<mailto:[email protected]>" Date: Thursday, 16 April 2015 13:03 To: "[email protected]<mailto:[email protected]>" Subject: [neonixie-l] Re: FLW Clocks I've been tempted - not with B7971s but with a 40 character VFD I have had in the JB for years. It could scroll six letter words and even jargon nicely and there are no gaps between the three groups of 2 digits as in the 6 digit clock. As someone else said, memory space is the issue - I built a FLW a few years ago and that one had about 4000 words in memory with is 16000 letters. That's fine for the 32K micro I used. The 6 letter word lists on the net have between 15000 and 22000 words depending on censorship level. Taking the larger number, that's 132000 characters which is quite do-able with a larger micro. On my FLW I kept all the dirty words and have a selector switch on the back to keep it clean when required, such as when the grandkids get fascinated reading the words. There plenty of VFDs on the e-place in the $100 range. Currently I'm using the VFD in a speaking clock that emulates the old telephone time service :-) Morris On Wednesday, 15 April 2015 20:41:13 UTC+10, celephicus wrote: Everyone on this list has heard of four letter word clocks.
