Wooden Digital Clock with
– Time, Temperature, Humidity, Alarm
– Wi-Fi controller through web browser
– Advance display config
– Stop alarm by vibration sensor
size : 64 x 64 x 79 mm
i use PLA with wood veneer instead of full wood
my room’s too small for put woodworking tools
If want view detail all steps, you can watch video

Step 1: PCB – Display
This step for make PCB (two layer) display module (if cannot do, you can find PCB Manufacturing Service)
I use MAX7219 for led driver and display with Led CEM3491, it have two dots for sec and upper dot for temperature
But CEM3491 is Common Anode, MAX7219 for drive Common Cathode, so must reverse pin Digit and Segment
Material list :
– (x1) CEM3491BY (0.39″ Common Anode 4-Digit 7-Segment Display Amber Color)
– (x1) MAX7219 (Led driver display)
– (x1) 10k Resistor
– (x1) 10uF Capacitor
– (x1) XH2.54-5P (5Pin Straight PCB Male Box Header Bar Connector)

Step 2: Program
I have complete program firmware, you just upload it to STM8S005C6T6 by software STVP-STM8 with file controller.s19
STVP-STM8 : http://www.st.com/en/development-tools/stvp-stm8….
hardware for upload : ST-LINK
if see “PROGRAM MEMORY programming completed” it mean done
about upload firmware, view detail in video at 10:35
