I enjoyed the kit! I really like the display but didn't realize it was so small. Since it was a combination boards using Thru-hole and SMD parts it went together really quickly and not too many parts as well. Think it took me 20~30 mins to get the clock powered up. The clock it self, once I got the suggested case from Mouser.com it fit as he said but needed a small adjustment, other than that it looks very nice and will look good next to my other built kits of other digital clocks I have made over the years.
I ended up buying the WiFi ESP8266 separate from the kit which ended up being a nightmare to say the least. Since I bought separate from the kit programming WiFi Module was a nightmare and was not the kits fault. I ended up with three modules now and none of them working. There are too many different instructions and conflicting information on how to restore the modules to factory condition and still have not got my clock online yet. If anyone knows how to help restore the WiFi ESP8266EX Modules please get hold of me. I even sent a message to the manufacture and tried there suggestion with no luck. I wish I had bought the whole kit including the WiFi module from him in the first place, would have saved me days of messing with it and a working WifiChron Clock Online.
Despite the trouble with the WiFi Module, It will be a nice addition to my collection!
The clock looks gorgeous and building it was a pleasure. The only problem? The documentation is a little bit chaotic and it's difficult to find what you are looking for. The email support from the seller is also excellent.
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.
Nice clock kit although it could use a little documentation. However, designer provides excellent support. I had a bad clock chip which he assisted troubleshooting and provide a replacement. It requires externally supplied 5 volts to support the clock chip which makes battery operation unpractical. However, it is easy to build and a neat, small clock. I may try replacing the clock chip with a lower power version and add a battery for a standalone clock. Thats the fun of open source hardware and software. All in all I am satisfied and with the support the designer provides makes this a project worth purchasing.
Updated 9/9 - Within hours of writing my original review, the board creator updated the Source code link to provide the missing files. The code built without problems, and the board works great. Thanks, FlorinC! I've updated my review..
The hardware on this board is well-designed. Although I'm not experienced at SMT soldering, I found it relatively easy to do on this board, since the board layout provides plenty of room.
The Source Code link provides all the files you need to build the project - no need to go hunting for libraries to download.
Overall, nice hardware design, fun build, and that bubble display looks even cooler in person!
