I have some front panels that I'd like to blink like in the movies. Since the human brain likes to find patterns, I suspect that pure random numbers are nowhere as satisfying as some patterns. Has anyone done research on that? Of course, I'll have multiple modes such as Conway's Life, counting in various ways, ring counters, etc. -- jeff jonas
A sufficiently complex pattern will give the impression of randomness and keep it from getting tedious to look at. On Wed, Aug 5, 2020 at 7:47 PM Jeffrey Jonas via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:

All I can think about is the WOPR. On Wed, Aug 5, 2020 at 7:50 PM Dean Notarnicola via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:

There is a cool program that I run on my pidp8 called deeper thought that could be put into a raspberry pi. Or just set up some caps and resistors that vary, with a 555 time to generate some random like effect Bill On Wed, Aug 5, 2020, 7:49 PM Dean Notarnicola via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:

That will work for a little while, but if they're fed from a common power source, they will very likely eventually sync up. Google "injection locking". -Dave On 8/5/20 7:59 PM, Bill Degnan via vcf-midatlantic wrote:

Decades ago, for a hardware project, I designed and built a shift register based LED color organ. I achieved a certain randomness by detecting one audio frequency that pulsed a bit shift at a regular rate while the frequency was present, and detected another frequency that was used to seed the input to the shift register. When music was played, the color organ swept through 24 LEDs in a linear manner, with random groups of LEDs being lit as the bits shifted through. I suppose something similar could be applied to your idea, but don't connect the lights in sequence. Connect them in a random order and the randomness of the bits flowing through will technically be in a specific order, but "random" in perception.

On the Battleship New Jersey, some of the digital displays appear to have a random pattern of lights. I was told that they used the seven segment display driver outputs from a digital clock randomly connected to the register lamps to get that appearance. So that’s 42 semi random looking bits available, especially if the clock is still running.
