This was supposed to be a simple project. I already had a set of 12 8×8 LED matrix modules, software, and a micro. All I had to do was print out a .3mf file, slide the modules into the prints, tighten some screws, and flash some software. The project ended up being anything but simple. Read on to find out what went wrong and how I got things back on track.

Le LED Cinema Display de 2010 est un moniteur encore assez efficace en 2026, mais qui a un défaut : il est uniquement Mini DisplayPort. Pour le connecter directement à un Mac moderne, il faut donc un adaptateur USB-C vers Mini DisplayPort, j’en avais parlé. Si vous voulez le connecter en HDMI, ce n’est pas possible directement. Mais il y a une solution.

Téléchargez ce fichier d’impression 3D gratuit conçu par Noah’s Thing Factory. This is a simple 2x2 gridfinity bit that is perfect for storing and organizing resistors. It has 10 slots for different values of resistors. There is a separate, optional tab that can be printed to add a label to the organizer. The open space in at the bottom side allows for easy retrieval of the resistors, and there is plenty of clearance to all allow for rolls of resistors to be stored without being removed from the adhesive strips. Boost MeIf you like this model, please consider giving it a boost! Thanks!

J’avais besoin de quelque chose pour maintenir, organiser, stocker ou transporter mes composants électroniques. L’idée que j’ai eue était de les brancher sur une carte qui pourrait maintenir solidement les broches tout en permettant un détachement facile
Il existe deux options : la mousse de polystyrène et les platines d’expérimentation. Cependant, les deux ont des inconvénients évidents. Je n’ai pas beaucoup de mousse de polystyrène, et les morceaux que j’ai ne sont pas de la bonne taille. Les platines d’expérimentation maintiennent les pièces trop fermement et sont trop chères pour cet usage
J’ai donc conçu une carte de base personnalisée. Les trous liés (ou élargis) – comparés à ceux d’une platine d’expérimentation standard – la rendent adaptée à l’impression 3D. La taille et la forme des trous ont été ajustées pour maintenir les pièces parfaitement

psutil is a cross-platform library for retrieving information about running processes and system utilization (CPU, memory, disks, network, sensors) in Python. It is useful mainly for system monitoring, profiling, limiting process resources, and managing running processes. It implements many functionalities offered by UNIX command line tool such as ps, top, free, iotop, netstat, ifconfig, lsof and others (see shell equivalents).

There are infinite varieties of cyberdeck you could make, each with their own inspirations. Today, [RadioactiveArtist] shows us a M.A.S.K. lunchbox cyberdeck faithful to the 80s show.

MicroPython implémente la classe FrameBuffer pour gérer l’affichage sur les écrans matriciels tels que les écrans OLED, LCD ou TFT. Cette classe fournit, entre autres, une fonction destinée à afficher du texte sur ces écrans.

Pour afficher du texte, cette fonction doit disposer d’une fonte au format bitmap. FrameBuffer fournit donc une fonte de ce type. Cette fonte est à chasse fixe et chaque caractère est dessiné dans une matrice de 8×8 pixels. Si, compte tenu des dimensions courantes des écrans, elle permet un remplissage optimal de la zone d’affichage, elle présente malgré tout trois inconvénients majeurs :

• sa taille est insuffisante pour assurer un confort de lecture correct ;
• elle n’est actuellement pas modifiable, et rien ne laisse penser qu’elle le sera dans un avenir proche ;
• elle ne dispose que du sous-ensemble imprimable des caractères ASCII, donc codés sur 7 bits, s’étendant de 32 à 126, ce qui interdit notamment l’affichage des signes diacritiques utilisés dans la langue française.

Dans ce tutoriel, nous allons voir comment générer des fontes bitmap à partir des fontes Truetype vectorielles et comment les utiliser pour réaliser un affichage digne de ce nom, dans les limites, bien sûr, des contraintes liées au matériel.

Nous verrons également comment optimiser l’utilisation de la RAM en pré-compilant les fichiers.

Pendant plus d’une décennie, concevoir une mise en page de type « Pinterest », où des éléments de hauteurs variables s’imbriquent parfaitement les uns sous les autres sans laisser d’espaces vides, relevait du parcours du combattant. Il fallait soit capituler et charger une bibliothèque JavaScript (la célèbre extension Masonry.js de David DeSandro), soit se résoudre à utiliser des astuces CSS bancales comme les colonnes CSS (columns) au prix d’un ordre de lecture totalement inversé.

midi2 is a small piece of infrastructure for boards that already have too much to do. Sound chips, displays, USB stacks, sensors, network. MIDI 2.0 arrives at the transport layer as 32-bit words; midi2 turns those words into structured events and stays out of the way the rest of the time.

The library implements 100% of the UMP format (M2-104-UM v1.1.2) and 100% of MIDI-CI (M2-101-UM v1.2). The application owns memory and decides which modules to link. The transport (USB, BLE, network, serial) lives somewhere else, by design.
