Wooden Digital Clock with

- Time, Temperature, Humidity, Alarm

- WiFi 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

Step 3: PCB - Controller

Next for solder microcontroller STM8S005C6T6 and other parts for complete PCB controller

button for reset wifi config, just hold down 3s and buzzer will fire beep sound

Material list :

- (x1) STM8S005C6T6 (Microcontroller)

- (x1) ESP8266-12 (WiFi module)

- (x1) ASM1117-5.0 (voltage regulators 5V)

- (x1) ASM1117-3.3 (voltage regulators 3V3)

- (x1) 470uF Capacitor

- (x1) 1uF Capacitor

- (x3) 10uF Capacitor

- (x2) 4.7k Resistor

- (x1) Mini Pushbutton Switch (4Pin)

- (x1) SW-420 (Vibration sensor)

- (x1) DS1307 (Real Time Clock)

- (x1) 32.768 khz crystal

- (x1) CR2032 battery

- (x1) CR2032 battery holder

- (x2) XH2.54-2P (2Pin Straight PCB Male Box Header Bar Connector)

- (x1) XH2.54-5P (5Pin Straight PCB Male Box Header Bar Connector)

- (x1) XH2.54-4P (4Pin Straight PCB Male Box Header Bar Connector)

- (x2) Cable Double Connector XH2.54-2P

- (x1) Cable Double Connector XH2.54-5P

- (x1) Cable Double Connector XH2.54-4P

Step 4: External Interactive

solder external interactive parts : dc jack power, switch, DHT22, buzzer

don't forget put heat shrink tube before solder

and make sure solder jack dc exactly polarity (+ -) with PCB controller

Material list :

- (x1) PCB prototype double side

- (x1) DHT22 (Temperature, Humidity sensor)

- (x1) C1815 Transistor

- (x1) XH2.54-4P (4Pin Straight PCB Male Box Header Bar Connector)

- (x1) DC power jack

- (x1) Buzzer 5V

- (x1) Rocker Switch On/Off

Step 5: Box Case

3d print with PLA filament 1.75mm, layer height 0.16mm

complete SLT file in attachfile, or build for yourself with custom size

Step 6: Assembly

link connector cable and arrange internal, external parts for fit with box case

require M2 bolt (x9)

don't forget put CR2032 battery

Step 7: Wood Skin

I use wood veneer sticker for apply skin simple

Step 8: Complete & Test

Input 9v power supply and turn on switch button to on wifi

Default mode is AccessPoint (mean wifi create from wood clock)

mode AccessPoint have default SSID : noname (no password) with ip 192.168.4.1

with mode Station (mean wood clock will join to other wifi) your device and wood clock must in same wifi network

after switch on and wifi ready, Led will show 4 number of ip, ex : 192 (--blink--) .168 (--blink--) .4 (--blink--) .1

then visit ip on browser, you'll see control page with 7 menu

- Home : display curent Time, Temp, Humi, Heat-Index

- Display : change Brightness and Type display time

- Time : config current time and digits

- Temperature : config temprature

- Humidity : config humidity

- Alarm : config alarm and sound

- Wifi : config wifi

<p>Can I get the coding of this project</p>
<p>Very nice job. Great video overview of what/how you did it. Very well done. You've included a lot of general info on WIFI, Packaging, Display, etc. that can be leveraged for other projects.</p><p>Thanks for your efforts, all the details, and wiliness to share!</p>
<p>Love that. Very interesting and a really good job. Thanks for sharing!</p>
<p>Very nice job. For me, most interesting is digit display through the veneer. Exactly what did you use for veneer? Is it wood or plastic? Thickness?</p>
<p>Its not wood at all. Its textured vinyl. Depending on where you live it will be called different thing. DIY stores in Europe will have it called &quot;Fablon&quot; (a brand). Not sure elsewhere. Just be sure to clean the case with alcohol or dirt/grease remover first to make sure the adhesive lasts.</p>
<p>I not expert about wood, so can't confirm wood or plastic</p><p>only thing i can sure it have waterproof and self-adhesive, like sticker, decal</p><p>back side have info manufacturer : &quot;SHIN LUNG - Product of Taiwan&quot;</p><p>i think same as this product : goo.gl/0ccA9y</p><p>that's all info i have, hope useful for you</p>
Thank you. Information is quite complete. It is plastic (PVC) with adhesive on back. How were you able to make display area transparent?
<p>just apply on led, light of led can through with good brightness, it made you feel as transparent area</p>
<p>What was the program that you used to design the PCB?</p>
<p>I use Eagle PCB of Autodesk</p>
<p>Great video - neat soldering and a quality project at the end! Top stuff!</p>
<p>thanks, with deep focus about soldering</p><p>i think you also expert about electronic</p>
Super cool<br>Does that mean it's displaying through the sheet
<p>Bro.</p><p>What the...</p><p>I can't...</p><p>How did you...</p><p>Could this be any cooler!?</p>
<p>i curious about your word unfilled :)</p><p>focus to main question, because esp8266 consume large power, so when enable wifi, heat will up at 5v &amp; 3.3v regulator ic (not hot, just warm)</p><p>if you use wifi for short time, so don't need cooler</p><p>if worry about result of temperature sensor, you can isolate temp-sensor by aluminum or silver foil, or drill some holes for air flow into box case</p><p>also don't use 12V power supply, heat will up, good power about 7~9V</p>
<p>That's my love. unique idea and easy DIY project. Love to ask my kids to make these kind of experiments. thank you </p>
<p>Wow that's really cool.</p>
<p>That's really really good :-)</p>
<p>thanks u</p>
Colossal!
<p>thanks</p>
<p>I love the way the clock looks with the veneer, it's really pretty :)</p>
<p>me too :)</p>
Its looking very nice with the veneer skin as only the lit LED is visible and other segment is not at all visible and covered with veneer layer.
