DA-2000 4-digit Numitron Clock

The 4-Digit "Wemos" Numitron Clock kit is a fully Internet enabled clock based on the Wemos D1 R2 mini. The Wemos clock connects to your WiFi and always keeps the time correct. Setting the clock is alse done with a browser using a computer, phone or tablet. Once you have set it up you can forget the clock. It will keep itself right forever.

In the case that WiFi is not available, the clock falls back to the internal RTC (Real Time Clock) time provider, so that the clock always shows the right time.

This kit is a simple to build (with excellent and clear instructions) and should take you only a couple of hours to construct.

The controller comes pre-programmed, and you can update the code using "Over The Air" (OTA) updates. You don't need any special programming equipment!

Note that this clock is currently not open source.

The wall power supply is not included. You will need to get an external USB power supply with a USB "B" ("Micro USB") connector on it. These are the same as used by smartphones, and you almost certainly already have one in a draw at home.

Tools, solder and some connecting wire is not included.

Full kit of parts WITH tubes: You get all of the electronic components on the PCB, as well as the tubes and LEDs.

Full kit of parts (no tubes): You get all of the electronic components on the PCB, but no tubes, which you need to get yourself.

PCBs and controller: You get the main PCB and the display board PCB, and a pre-programmed wemos controller. You will need to source all of the other parts, which are easily available from distributors or Ebay. We don't use very hard to find or special parts.

PCBs only: You get the main PCB and the display board PCB. You will need to source all of the other parts, which are easily available from distributors or Ebay. We don't use very hard to find or special parts. You will need to flash the controller with our firmware.
