seven segment LED clock (ESP8266 + WS2812b)

thingiverse

Just another seven segment LED clock. <a href="https://gitlab.com/jdobry/7segment-led-clock/tree/master/firmware">Current version of SW</a> working, but it isn't final version. What is working: * time on dislpay * synchronization from NTP server * time in local time zone. This zone must be specified manually on source code like "Europe/Prague". See <a href="https://en.wikipedia.org/wiki/List_of_tz_database_time_zones">https://en.wikipedia.org/wiki/List_of_tz_database_time_zones</a> * extreme simple web interface to allow select LED color and brightest. * connect to internet over WiFi. Network name and password must be specified manually in source code. * ambient light sensor and automatic brightest control.(need APDS-9960 light sensor module) * local RTC suport as clock source backup (need RTC module based on DS3231) Features in todo list: * show temperature from internet connected weather station * better web configuration * user friendly WiFi setting It is almost fully parametric OpenSCAD design. Generated STLs are for 110mm digits, but you can create size as you want to have. https://youtu.be/EEWWbuWJh8E <a href="https://gitlab.com/jdobry/7segment-led-clock ">OpenSCAD source files are here</a> List of material (4 digit version "88:88"): * <a href="http://s.click.aliexpress.com/e/COMHKB7a">Wemos D1 Mini ESP8266 board</a> * 1m <a href="https://www.aliexpress.com/item/1m-5m-WS2812B-Smart-led-pixel-strip-Black-White-PCB-30-60-144-leds-m-WS2812/32636234899.html">1m WS2816b strip, 60 LEDs/m</a> * 2pcs <a href="http://s.click.aliexpress.com/e/FVrQTsMu">WS2812B PCB Board 1 led Pixel</a> * 6pcs <a href="https://www.aliexpress.com/item/304-stainless-steel-cylinder-head-bolts-screws-HC-HM-knurled-screw-cup-head-bolts-M2-3/32571200037.html">M3 x 12mm screws</a> * 6pcs <a href="http://s.click.aliexpress.com/e/kEqNo1Og">5x5mm M3 brass inserts</a> * 1pc <a href="https://www.aliexpress.com/item/32738206621.html">GY-9960LLC APDS-9960 RGB Sensor Module</a> List of material (6 digit version "88:88:88"): * <a href="http://s.click.aliexpress.com/e/COMHKB7a">Wemos D1 Mini ESP8266 board</a> * 1.5m <a href="https://www.aliexpress.com/item/1m-5m-WS2812B-Smart-led-pixel-strip-Black-White-PCB-30-60-144-leds-m-WS2812/32636234899.html">1m WS2816b strip, 60 LEDs/m</a> * 4pcs <a href="https://www.aliexpress.com/item/Wholesale-10pcs-WS2812B-5050-RGB-LED-PCB-Board-1-LED-Module-Pixel-Light-5V-with-heatsink/32523516771.html">WS2812B PCB Board 1 led Pixel</a> * 12pcs <a href="http://s.click.aliexpress.com/e/FVrQTsMu">M3 x 12mm screws</a> * 12pcs <a href="http://s.click.aliexpress.com/e/kEqNo1Og">5x5mm M3 brass inserts</a> * 1m alluminium "L" profile 10x10 mm for stand inner reinforce * 1pc <a href="https://www.aliexpress.com/item/32738206621.html">GY-9960LLC APDS-9960 RGB Sensor Module</a> EDIT: * 2018-10-14 information about preliminary SW * 2019-01-04 update SW status * 2019-01-08 add segment order picture * 2019-03-25 there is <a href="https://github.com/ropg/ezTime/issues/38">problem with daylight saving change on used ezTime library</a>.
