I build many clock kits. Have made many including Nixie, VFD and large digit LED. This was my first based on the HP HDSP 3534 matrix display. Wasa relatively simple clock to build, but the instructions could have been a little clearer. Had to contact the seller for clarification, but the response was fast, and clear. You can watch my build video on my youtube channel 12voltvids
I have been led's and clocks since buying my first led in 1969 at a military surplus store in London - it was vey expensive and dim. The kit was well packed in an antistatic bag. Very simple to put together, and it worked no problem. Setting is very simple. If there really are 770 "proverbs" (is "He's dead Jim" ann actual proverb?) in there, it's going to take some time to see them all. Anyway, it will be a good addition to my growing collection of odd digital clocks.
