Works great, looks great and fairly simple to put together if you know what you are doing.. If you are new to electronics it will be a little confusing as to which way certain things should be. Only 'complaint' is that as far as I can tell there is no way to stop the LEDs from flashing natively, so will need some modification.
This is a great kit if you want a non-multiplexed display with (static) individual drivers for each segment. Just like we used to make in the 1970's when LED's and TTL IC's first became available. The LED drivers can drive relays, optocouplers etc. to switch a much larger display e.g. 36W Fluorescent tubes. If you want to cast this board inside a block of clear plastic, fit reed switches where the pushbuttons are.
yes, I receved now. Good service.
Excellent kit, would recommend
It is all ok and arrived very fast. Thank you.
Clock does not work at all. All segments light up but nothing happens. Middle switch changes the minutes but only up to 39. Left switch does nothing. Does not count the seconds. I replaced every IC with new ones but it still does not work. All components are installed correctly. All connections are properly soldered with no bridges. Only thing I can think of is that the board is faulty. All ICs were handled properly using static protection measures. The only thing that works is the far right switch which turns the colons on and off. Don't buy this clock.
