I'm offering for sale the Numitron electronic clock full assembled and tested. 

 This is made around the kit developed by Jan Sparkes (nixieclock) - a full

 internet enabled clock based on Wemos D1R2 mini. Wemos clock connects to

 your WiFi and always keeps the precise time.  The clock' settings are done with a

 browser using a computer, phone or tablet: once the clock is setup it will keep

 itself right forever. If WiFi is not available, the clock shall use its internal RTC

 (Real Time Clock) time provider backup, so the clock shall display the right time.

A few technical features:

- 4 digits 12 or 24 hours format (HH:MM), selectable

- a large combination of LED backlight colors, selectable

- LED separators 

- LDR (Light Depended Resistor) available to control the dimming of the tubes

- the current date will be shown in the date format you selected 

 The clock comes with 4 pcs. of vintage Numitron tube model DA-2000, made

 by Apollo (US), with 15 mm digit height; the tubes have been mounted with

 dedicated pins on PCB display, for easy replacement.

The clock is powered by a 5Vdc wall power supply (included). 

 Please note that the backup battery (model CR1220) for RTC is not included, due

 to custom regulations.

The kit has been enclosed in a old vintage ammeter case (coming from years '70),

 with glass window; the case has been cleaned, polished and painted receiving a

 "new life", in a "new role".  

The clock has the following dimensions: 14.0 x 14.0 x 8 cm.
