7 segment LED clock

7 segment LED clock. Simple to print and to setup.

Functions:

• RGB LED clock with web configuration page.
• The time and date value can be displayed in different colors.
• The colours and intensity can be controlled with the internal web page.
• The device is hooked up to your network with the WiFi Manager.
• During startup the current IP-address is shown on the display.
• During startup an initial LED test is performed that can be turned off in the settings.
• During night times the LED intensity can be reduced to set to 0. ***
• The 2 points blink every second. They and be turned off or set to on permanently. ***
• The size of the clock is 205.5 x 105.5 x 45.5 mm and fits well on 210x210mm print beds.

Parts used:

• 1x Arduino ESP8266 D1 mini
• 30pcs LED chips WS2812B Ø9.75mm
• 1x Barrel jack for power input Ø12mm
• 1x 5V / 2A power supply with barrel jack connector
• 1x Transparent super glue to glue the white front parts into the case
• 1x Some wires in different colors
• 7x M3x20mm screw

Wiring the parts:

• The single LED chips are soldered together to a single chain.
• The 2 point LEDs are at the end of the chain as shown in the pictures.
• Connect the 5V pin of each LED to the next LED as numbered from LED 0 to 29.
• Connect the GND pin of each LED to the next LED as numbered from LED 0 to 29.
• Connect the DOUT of each LED to the next LED as numbered from LED 0 to 29.
• The DOUT pins of LED 29 stay unused.

LED order:

Mounting the LED chips:

• Press the LED chips in their holders as shown in the picture. No glue needed.
• Check the orientation of the LED chips again before soldering the wires to them.
• Add solder to each pad to add the wires later to them more easy.
• Add solder to each wire end too before soldering them onto the LED pads.
• Check that each solder point looks nice and shiny to avoid “cold“ solder connections that might cause problems later in the use…

Code:

• The needed code can be found in my GitHub repository.

Web configuration:

Printing instructions:

• Textured sheet used
• 0.2 quality profile used for the “segment” and “point” parts
• 0.3 draft profile for the “case" and the “lid” part
• Supports needed for the “case” part from the print bed
• 5mm brim needed for the “case" and the “lid” part
• Print the base part in a darker color
• Important: Print the “segment” and “point” parts in white color

Notes:

• Complete code will follow… Currently in progress… Basic version online. =)
• The next version will be able to install without the need of glue. 
• Instead of the single LED chips I would like to use LED stripes, because the wiring takes quiet some time…

Happy printing :)
