Cool project, it has given me an idea.

Now you need to combine it with a WWVB receiver so the time is always accurate.

Found an arduino project that uses WWVB.

Easy for Chronoless, I assume it will.
Well, easy in the sense that the designing and engineering is done. Though it still is a lot of work. Especially the casing. However it's still a prototype and there is much that can be refined.

Thanks for the tips on the WWVB receiver. I considered using it before. But it would be DFC77 for Europe. However at that time I really wanted to see the final result and figured that a DS1307 RTC would be ok for this first proto.

Over the last few days I've received quite some mails from people interested in buying one. I'm now going to ask around to see what the possibilities are of producing a small series. But it's something I'll have to do next to my normal job smiley.

Well if you can get the electronics done, I can do you the acrylic for a good price, PM me if you want.

My idea is to do something similar but the hour hand would light up on the inside of circle so it is more obvious what is minute and what is hour.  Actually, I will probably not do a loop design, but something with frosted glass/plexi.

I would like to add a date and day of week indicators also, I will have to think about how to do that creatively.  Alphanumeric segment LEDs take up a bunch of pins, correct?  any good way of accessing several of those on an arduino?

I might have a bunch of TLC5947s left over from my current project...

Chronoless, I don't know if you heard of kickstarter.com, but I think your equinox clock could enjoy unbridled success.
You can count on me as a contributor.

Wonder how much easier a project like this would be to make using SPI controllable LEDs such as these from bliptronics.

http://www.bliptronics.com/item.aspx?ItemID=114

60 of theses would come in at 70-80UKP for the LEDs but require no additional circuitry - just 4 wires.  I've got a bunch of the 20mm ones and they are very nice (christmas lights project which will ultimately become mood lighting for above the bedroom wardrobes).

I'm seriously considering having a go - perhaps a thick MDF backplate routed out with space for enough gap for mounting the LEDs and the "lenses" and a nice black acrylic face plate.

If only I didn't have a job and wife to maintain - I'd be in the garage right now smiley
