Note that this is still work in progress - I have projects beyond just a clock using these modules ;-)

That's the controller; the PCB is available at oshpark.com

And here's how it's wired:

(a simple meanwell 24V power supply with ability to adjust output to >=27V powers the thing, not visible on the picture)
