The (long) story of the relay clock

<< < (4/13) > >>

edavid:
Hey OP, how about posting schematics of your counter circuits?

I think I would have been tempted to start with a regular MCU based clock and add some software controlled relays as noisemakers - but I'm lazy.

JVR:
Damn. I wish I had the time to do this kind of stuff. Well done on getting that ratsnest to operate, even if it was a little flaky in the first revisions.

SiliconWizard:
Given there would be so many ways to get the same result and appearance, or pretty similar, with much simpler appraoches, I'm baffled how the OP got the courage and patience to do this.

Spemo:
Hey,
Schematics will be posted - once I'm done remaking then - to maybe make them more understandable. I hope I have it done this night.

Seriously, my sincerest congratulations and respects.  :-+

One comment about your video: it seems that there are sudden brightness jumps on the LEDs. Having attempted to video record LED displays, I know that sometimes the camera's auto-exposure function gets confused by the extreme contrast and will cause this.
Are the brightness jumps real, or is it a camera exposure artifact?

Thank you!
The brightness jumps are intentional - they are different brightness settings. This got removed in later versions.

I don't have problems with exposure there - the bench is extremely well lit, one day I found some LED panels with 512 high power SMD LEDs... at the moment I have 6 of them lighting up everything, 2 additional smaller lights (40 watts each) in the background. powerconsumption for all of this: 420 Watts  ;D But it's the only way to get my phone to shoot some usable footage.

Spemo:
As promised, here is the "Schematic" I use to build this monster - maybe one of you can find some use with this.

Have a nice day

Daniel
