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

First experience with wood

I received a jigsaw for my birthday, so I used it to enhance the cage of my two guineas pigs.

 

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 …

Fake journalism and trading

It happens almost every day, even with adds blocker you have articles about how you can easily earn a lot of money from home. I usually ignore those articles, but today while I was surfing, one of them did catch my attention because there was the name of my town in it.

dordogne

Translated it means : a housewife at Saint Antoine la villageoise sur Dordogne (no that town doesn’t exist) earns 8,350€ per month and you won’t believe how !

First of all, I hate this kind of title because it sounds like the viral sh*t you have on Facebook like : “this father jumps from a cliff while holding a bike, but when you will discover why he did this, you will burst into tears !”.

Then the name of the town, the content displayed on the page depends on some parameters, in that case the location of the visiter. This parameter is passed through the url in that case and therefore can be easily modified (that’s why the title says Saint Antoine la villageoise sur Dordogne, I modified it).

The name of the town is used in order to catch the attention of the reader ( and it worked on me), because you know that it is something that is happening right next you, maybe that you neighbor is earning thousands of euros per month without moving out of his couch.

The title is not the only thing interesting I found in this article, let’s analyse some others aspects that can be found in it, and then I will give my opinion about this kind of “journalism”.

DIY Alarm clock – the result

I have finally finished my alarm clock and here is the video to show it :


There are some details that could be added but at some point you have to decide to stop !

Here the main feature that was not described before in my blog :the alarm time is automatically set according to my Google Agenda and to Google Maps forecasted journey time.

I want to make the source code available for free, but I have to “clean” it first.

Enjoy 🙂

Debating in Copenhagen

Last week-end was quite exhausting for me.

I went to represent my school (or at least try) to a debating competition in Copenhagen hosted by CBS (Copenhagen Business School). The debating style was British Parliament and there were 5 rounds before the semi-finals. We finished in the second half of the ranking but it was an interesting experience. It was also an occasion to practise our English : debating is especially useful to enhance your fluency.

I also had the chance to discover the city and visit it in spite of the cold and bad weather.

During the return to Toulouse I had my flight cancelled from Frankfurt to Toulouse, the good new was that I had the possibility to take a lot of pictures on the huge hub that is Frankfurt Airport. I’ll post them on my website as soon as I sorted them.
