    So, I am asking you to be patient and give me some more time to receive the new
    re-manufactured boards and to assemble the clocks with this new boards.

    Sorry.

    Thanks for your understanding and patience.
    No rush! 😊

    I am still very interested in this and willing to wait for it to be done right. Thanks for building these!

    Hi Shep,
    thanks for the hint... good addition to my parts list.

    @ all,
    will finish the clocks as soon as possible and keep you updated
    on the progress.

    Rob of DeClock fame clued me into that one. You can thank him for that


    Couple other points:

    1) if anyone has an empty shell or completely destroyed clock, hit me up via PM and I'll buy it off of you. This shell will go straight to reverse engineering and reproduction via 3D printer. I have an amazing knack for reverse engineering parts these days, and this is one that I will post to Thingiverse so anyone and everyone can print at their convenience at a place local to them, no cost involved in getting the design, only in getting it printed. I can offer printing too at cost, need to figure out what that would be on my end, but will be low.

    2) Yoda, I always complete one and ONLY one board of every batch first to confirm it works 100% correctly. Once I know it does, I solder up the rest. Saves me in component costs too when the design is bad.

    By the way, I've thought myself about redoing the clock also in the past, but it's too small and complex for my current electrical capabilities. I can't SMD solder, so that throws a lot out the window. Good to see fresh young talent looking at it though so I can pass along ideas!

    A large capacitor is a great sit-in for a cell battery. Every time the key is turned to ACC, the capacitor charges up. This conclusion was arrived between myself and another electrical guru on the forum here I collaborated with on the idea. Standby draws milliamps, so it's really not needed to put a battery in there that will only need to be replaced.

    Also look into GPS. Multi-million-dollar satellites and we only use it for time. But hey, it works. All you need to do is set a time zone and you're set. I've been running one beside my bed for 2-3 years now, and the only times it skips a beat are when it misses the signal, which is easy enough to tell. It's my travel clock too. As soon as it's plugged in, anywhere from 10 seconds to 10 minutes later and it's synced up again. And this guy is one without any sort of battery backup at all, so as soon as that power goes out, it has to find it from scratch, every time. 10 minutes was the longest, and that was in the basement of a 3-story house in cloudy and stormy weather. 99% of the time it's within 3 minutes.

    Hi Shep,
    thanks for the feedback.
    I just assembled 2 boards (NOT MORE) to make sure the mistake is not on my
    side, but due to a serial defect from the board manufacturer.
    So now I am sitting in front of a pile of parts and wait for the new boards... ;-)
    ... I'll keep you updated...

    ... finished the second batch!

    I have assembled the PCBs, uploaded the program and tested them.
    They are ready to be shipped.
    Take a look at the picture.
    Tomorrow I will PM all of you, who were interested and waiting for these clocks, to
    arrange shipping details.

    Talk to you soon...

    For anyone who wants a direct plug-in fit (unless you can get them on your end Yoda? Would be a nice bonus to quite literally plug-and-play!)
