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 […]
Synology DiskStations are awesome. The DSM web interface is both powerful and easy to use and is constantly improving. One thing I have struggled with, though, has been setting up public key authentification in order to allow automated scripts to push backups to the NAS via rsync. Here is how it can be done. First, […]
I finally found some time to upload the few tutorials I’ve written. They are available here or in the menu at the top of the page, all under the CC BY-NC-SA license so feel free to use them in your courses or presentations. If you do so I’d be happy to hear about it!
What to do with a 3D printer which doesn’t want to 3D print anymore? Why not convert it into a CNC router to engrave PCBs? Learn more about that project here.
kicad2bom is a simple tool which is able to extract the list of components from a set of Kicad projects, apply usual select/sort/filter operations, and output the result either on the standard output or in a CSV file. Its goal is to make generating components shopping cart as quick and easy as possible (when used […]
