Threw this together last week using a DIGWDF 675+ controller... it'll be connected to a single SSR channel from a MiniRen8/8XB... Power on the channel, the display runs... turn the channel off and it goes dark...

That is a very nice piece Dirk!
With everyone going pixel crazy it is nice to see some traditional props still being built.

Thanks. I think giving visitors many different kinds of things to view is important and enhances their enjoyment. All-pixels all the time is tiring to the eyes and they need a break.

I agree, and simplicity trumps "tired eyes" every time.
What are you using to provide the animation? (You might have said, but I'm a bit 'thicker' tonight than usual.)
[Actually, I'm not sure what the 675+ controller does.]

The 675+ is a small, 4-channel controller using the PIC12F675 chip with a DirkCheapSSR all on a single board. You program the 12F675 chip with a sequence and when you power up the chip/ssr, the sequence runs itself without talking to the PC at all. It's designed for standalone, self-running display pieces. I use it in several display pieces where I want a little animation but perhaps only have one available channel left on a controller. I use that channel to power it on/off, so in effect, one channel in the sequence controls four others that are flashed into the 12F675 chip.

Naturally, the 675+ is one of those weird creations from the DIGWDF lab... here's more info...

How do you program a sequence into the 675+ ?

It's coded into the firmware, David. You have only 4 channels so you turn thing on/off and insert delays between as you need, then have it loop back to where you want it to continue.... it's a piece of cake and simple to do.... Here's the section for the sign -- Led1 turns on the text portion of the sign, Leds 2-3-4 are the bells...

Led1_ON
call Delay_100mS

Restart_Bells:

Led2_ON
call Delay_400ms

Led2_OFF

Led3_ON
call Delay_400mS

Led3_OFF

Led4_ON
call Delay_400mS

Led4_OFF

Led3_ON
call Delay_400mS

Led3_OFF

goto Restart_Bells
