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
