I was recently tasked with upgrading the servers of a small company. After defining the requirements and thinking about the architecture of the whole system, I decided to document the setup here as a guide, both as a reference for my future self (my memory works in a if-I-didn’t-write-it-down-it-didn’t-happen kind of way) and hopefully to […]
So, you’ve come back from a trip or a photo shoot, you’ve spent an unreasonable amount of time in Lightroom or RawTherapee fiddling with the smallest cursors, and you now have a folder full of images that you would like to proudly share with the world. But how? Of course, you can post your photos […]
View the project on Github : Managing servers is not always easy. You have to balance reliability, security, and user requests for features. One common issue arises when a regular user needs to be able perform some task on a server, such as restarting a service, changing a configuration, or updating a software, but you […]
This is the long-overdue, direct follow-up to the first build log. The rocket is now finished and should be launched during the summer. Let’s go ! Motor stage There has been a few improvements to the parts shown in the first article. First of all, I was getting a bit concerned about the relative fragility […]
I’ve been doing a lot of resin casting lately, and as usual, the needs of one project led to many sub-projects. This is one of them. Keep reading if you are interested in the story, or skip to the end if you only want to download the source files. For those who are not familiar […]
I am currently in the process of porting an Android app and I am therefore learning Kotlin at the same time, since this is now the recommended language for Android development. I have to say, I like this new language a lot : it reminds me of the conciseness and expressiveness of Python but with […]
The last post about this project aimed at building a long-range camera remote control ended with a few working prototypes in need of a case. Designing such a case to be practical, good looking and easy enough to manufacture in small quantities proved to be way more complicated than I expected however, and it lead […]
CanSats, like their name implies, are small satellites designed to fit into the volume of a 33cL can of soda. They are launched from a balloon from an altitude of about 150m and must perform some missions while descending under their parachute. The French CanSat competition takes place every year during the C’Space, the event […]
Update : see the new version here. Wired remote controls for DSLR cameras are incredibly cheap and are easy to find for about any camera brand out there nowadays. They prove very handy when you need to trigger the shot while you are away from the camera, such as for studio photography. The better ones […]
Wait, Cortex 2? Where is the first one? Cortex was a minirocket project launched during the 2018 edition of the C’Space, a French event allowing students to build and launch experimental rockets. It featured an entirely 3D-printed structure, embedded recording of physical parameters, a Bluetooth configuration interface (via an Android app), a GPS and a […]
