Video : homemade worldmap clock

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 !

Video – tips with WS2818b

Hello everyone,

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

Wordmap clock

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.

Steering wheel commands on my carputer

After a lot of work on my homemade carputer, I finally found out how to get the steering wheel commands on my carputer.
I made a video to explain how it works and how I did it :

I used and arduino with a Can Module to read the messages. In the video I explain how the Can Network is organised and how to get the message to know what is happening on the steering wheel commands.

Enjoy 🙂

Carputer with Raspberry Pi

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.

Arduino SmartClock – Nano version, the result

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 ;-).

Arduino SmartClock – Nano version

After having successfully created a SmartClock with Arduino, I decided to do it again but smaller !

As I want this project to be more colorful, I found an alternative to simple RGB led. The module is called WS2812 and it is simply awesome !

The modules are fairly easy to use and are connected on cascade. You can simply control the color of every LED separetely.

Description of the module : here

One powerful WS2812

For now, I’m using the Arduino Uno for prototyping, but in order to have everything in a small box I’ll use the Arduino Nano Pro.

Here is what it looks like now :
