Here comes a quick article on a quick (and ugly) fix on the Ender 3.
I recently bought one and I’m very happy with it. However it is incredibly noisy. In order to fix that, one solution is to buy cheap dampers for the X and Y steppers.
On my version I could not remove the belt gear piece and I noticed that I wasn’t not the only one (thread on reddit).

On other version you could unscrew it, put the damper and then put it back in place. On mine it is fixed. Instead of trying to remove it and maybe break the stepper and i took an easy and (sorry) very ugly solution : using a file and a rasp to remove enough matter so I could pass through it.
It worked perfectly for me, and I didn’t notice any drop in print quality. However the Y Stepper being bigger it reduces slightly the Y-range so I had to move the endstepper on the Y axis (about 1 cm) as you can see on this picture :
That’s it quick fix, not a lot of details but I hope it will help other people who are stuck the same way I am.
What ? Yet another alarm clock ? Aren’t tired of doing that ?
Oops, I did it again. Actually it is more of a second version of the first one I created (here to know more about the first version). It fell down on the floor so I decided to remake one. It took into the account the defaults that I saw with my first one.
The biggest flaw was that the led display was too bright at night so I decided to switch to the simple TM1736 module (same as in the NanoClock project).
This was also the occasion to use a lot of the leftovers I had at home. I already had all the components : I just had to buy the wood board which costed me 4€. Otherwise I estimate the total cost of about 20€ (Virtual Private Server excluded of course).
As I said in this video, what I really liked about that project is that it was a mix of two different things that interests me : Arduino/electronics & wood (kind of like with an other clock, I promise it is the last one : wordmap clock).

This a very short post to talk about a very interesting and natural phenomenon that I had the chance to spot few days ago : waterspout. It is like a tornado and water but usually way smaller.
It is not the first time I see this, however it is the first time that I see more than one at the same time. It is also the first one that I could take a photo of.
There was no damage reported this day.

I’ve haven’t been active on my blog recently but I have a good excuse : I just got married.
This article is about the two different items that I crafted my self in wood.
The box for the rings
The idea was pretty close to what I’ve done for the proposal. I used the same material : oak and also the same technique. The dimensions are different and I had to make room for the locks on the side.
The box closed with the locks in place
The idea behind the locks is that both of us were accepting to get married, as you need two keys to open it.
The keychains were made by an embroidery in Toulouse (I tried to look on Internet but you usually need have to buy 100 of them or plus …). Instead of the classical Remove before flight it says remove before KISS. And there is the date of the wedding on the other side.
The inside was made with leftovers from an other project. The tissue is made of felt and I used a sewing machine to make it nice and clean. The inside is stuffed with polymer fiber (the same you use to put in stuffed animals for instance).
I’m pretty happy with the result. The only detail that I didn’t like is that the lid is not straight enough when opened. But otherwise I feel like I improved since my last creation made of wood. It is also a good souvenir that we will keep with us.

The donation box
The other project that I made in wood was the box used for donation. It was to help us to pay our honeymoon so I made it in the shape of an aircraft. The wood is pine.
The back of the box was closed with plywood and nails and I had to tear out once the wedding was over.
It was the first time that I used a plane (the tool not the airplane) to have a better finish. I used woodpaste to hide the screws even if you can still see it.
So that’s it ! I hope you liked and I also hope that one day this will give some inspiration to someone else.
As Air Traffic Controllers we are sometimes being notified by pilots about events. Sometimes it can be a fire, or a boat in distress. But when calling the competent rescue service it is not always easy to communicate accurately the position of the event.
Dash 8 and Trackers S2T at Cannes
In aviation we are using nautical miles, a unit that a firefighter will never use (expect if it is for sea rescue). That’s why I created a small tool called BalthaSAR (the name is a pun, SAR stands for Search And Rescue).
The principle is simple, the website converts position of starting point (can be an airport, a VOR or an NDB) heading and distance to coordinates of the reported point.
This can be easily measured on a radar screen.
The point is showed in red on a map, the squares that you can see on the pictures or DFCI coordinates (which are French coordinates used by fire fighters and sea rescue)
The text is in French, and it contains only coordinates for French airports and Navaid (from the openaip database) but can be easily adapted for an other country.
The website is hosted on Github and can be seen here : https://abartben.github.io/balthasar/
The source code is available here : https://github.com/abartben/abartben.github.io/tree/master/balthasar
The work and the website it self was not hard, it is more a compilation of different libraries (mapbox, bootstrap, coordinates converter …) than coding it self.
I hope this will be useful in the future !
I haven’t posted on my blog recently and yet I took a lot of pictures. Fall is here and is progressively giving its place to winter (but don’t worry winter in the French Riviera is easy to support).
Two pictures were taken during a flight around Cannes in a brand new APM30 (nice light aircraft by the way).
Two others pictures were taken from the Lérins Islands. Those are small islands near Cannes, you have to get there by boat. It is a little expensive but totaly worth it. However if you want to get there I would recommend to not do it during summer.
Finally the two last photos were taken at the Mt Vinaigre (the highest moutain in the Esterel, but only 614m high, nothing compared with the Alps).
If you like my pictures you can find all of them in High Quality on my Flickr account
Two days ago was the new moon, the best moment to take pictures of the sky. So I took my camera and my tripod and went along the coast to try to shoot the stars.
The French Riviera is a very dense place with a lot of lights, so not the best place to have clean shots of the stars. However there is a small reserve stuck between two cities where the landscape is beautiful and the lights are few, that’s where I went.

Equipped with my Canon EOS 700D and my wonderful Sigma 18-35mm F1.8, I took this :
I found this experience very magical, the camera is like a magic eye. Once correctly configured it is able to see beautiful things that the naked eye can’t see.
