Very good price for a nice 24 hour clock...
For ESP8266 Led Matrix Clock DIY Kit
I've been looking for a clock for the ham shack for a while and this one caught my eye. It can be set for any time zone and connects to NTP servers periodically to stay accurate. It is easy to build with what would be the tough part (the surface mount chips and headers for the LEDs) already installed. I bought the kit without the remaining headers installed. It took me about 30 minutes from start to finish and less than 10 of that was with a solder iron (and the rest involved a lot of double checking I was doing things right). Not a lot of documentation on construction, but it is very straight forward an easy to figure out. The only downside to me was having to install yet another (I've lost count of how many I have installed) tool-chain to program the microcontroller. I don't use VScode, so I installed the CLI only on my main Linux box. I have a pitifully slow internet connection, so that took a few minutes. It is pretty easy to figure out which files you need to move to which directory. Then a './pio run -t upload' and things started. The first time, there was a lot of downloading and installing. (After all was said and done, the directory it creates and uses had 2.9 GB of 'stuff'...) But things uploaded. I connected to the serial port, rebooted it, and saw the WiFi come up. It was easy to build and easy to configure. I need to spend some time in the code because I'd rather just see the clock and not have the day of week and date appear periodically. This is a great kit and a great value for the money. The only two complaints I have are the new tools taking 2.9 GB on my machine that I'll probably never use for any other project and that the code doesn't seem to have all of the things you can configure (time zone, brightness settings, etc.) clumped together in one place for ease of use. But if you're a bit of a geek who has messed with Arduinos and other microcontrollers, those are just minor in the overall scheme of things. The result is a nice looking clock that will stay accurate.
