I’ve juste uploaded a short video showing the different steps of the creation of my worldmap clock.
It was a highly interesting project, as it was the first time that I mixed two different things I like : IOT & woodworking. It don’t have much experience with wood but I love the idea of making something from trees !
as promised here is the video explaining how I soldered my LED’s to create the display in my worldmap clock project.
As stated in the video, the module used is Ws2818B which are individual RGB leds individually controllable .
I bought them by 100 on Banggood for about 15€
I found a lot of useful tips on how to power it and use it properly on Adafruit’s website (which also the provider of the library to control it) Adafruit Uberguide for Neopixel
Inspired by some wordmaps made with nails found online, I decided to build my own with a little modification : it’s also a clock and of course a connected clock … I know what you are about to say, yet another connected clock ! And well … it’s true (first project, second project). But this one will be pretty !
The “background” was made using painted 8mm thick MDF and the frame was made using fir wood.
LEDs are WS2818 which can be individually addressed in order to have results like this ! In this project there are 82 leds that needed to soldered (6 points per LED). It’s a lot of word, I’ll soon post a video explaining how I did it.
I will add more behind the “background” to light the wall on which it will be hanging. And I still have to work on the Wifi connection using ESP8266 module and Arduino.
After my first project with wood I decided to continue and buy new tools (including circular saw). Here is what I did using pine wood for my sister’s birthday :
It was a very fun project and I learnt a lot like how to properly sand and how to use wood paste to hide the screws.
I received a jigsaw for my birthday, so I used it to enhance the cage of my two guineas pigs.
Some wood ! Yummy
The cost is very small as most of it was done using scrap wood. This small project was interesting because I could test 3 different type of cuts using the jigsaw :
- Straight cut on the stairs and for the hut
- Cut following a curve for the upper stage
- Circular cut for the “window” (yes it was supposed to be a window but they decided to use it as a door, well it’s your cage …)
They adopted it the day I set it in the cage. To help them discover the upper part I baited them with some fruits and it worked pretty well.
As said with the title, this was my first experience with wood and I really liked it. Maybe one day there will be an other project with wood …
Yet another project !
I was tired of listening to the local radio on my car, I wanted my own music. So in that case you have 2 possibilities: either you buy an other system or you build yourself a super carputer ! Needless to say that I chose the second option.
In this article I am going to describe the different choices I made to build it, but this is not going to be step by step tutorial to build yours.
Here is the final result on my nano version of the Arduino SmartClock
The new clock in font of its older brother
It is a simplified version of the Arduino SmartClock but also smaller.
Like the other model, it is an arduino based clock that connects to my home wifi in order to automatically set up the time (wifi module ESP8266).
It is also an alarm clock, the time of the alarm is also set via WiFi. There is a mode where the alarm is automatically set according to my schedule on Google Agenda and the time forecasted for the journey by Google Maps (by car, because of traffic jams and my variable schedule, this can vary a lot from one day to an other).
Instead of using a light sensor, I set up two simples modes : Day & Night. By day the seconds are shown in a colorful way :
Display by day
By night the luminosity is lower and only some LEDs are used :
Display in night mode
The code is fairly close to the one of the preceding version (reminder : the code of the clock itself is freely available here ). The soldering was more challenging as there not a lot of room available inside of the box.
Inside of the clock
To finish here is little tip :
If you’re building a project inside a box with a power cable (or any type of cable going outside of the box) you can make a knot with the wire inside. That way, if you pull on the cable, it will only tighten the knot and not unplug or break the wire ;-).
The simple knot trick !
