Analog synths are fun because they combine music, which all humans seem hard-wired to enjoy in one form or another, and electronics, which… uh, this is Hackaday. If you don’t like electronics, we’re not sure what to tell you. This hack from [Sound Workshop] takes the cheap, toy-like Otamatone and turns it into an older and more capable type of synthesizer: a Trautonium. The video below also includes a dive into the different types of early synthesizers, with examples of them playing, so it’s worth watching for that alone — if you know the history, skip the first five minutes or so.
For those of you more into the electronics than the music side of things, the Otamatone is kind of like an electronic...

Le vice-président américain, J. D. Vance, qui dirige la délégation des Etats-Unis, a pour sa part quitté Washington vendredi pour ces pourparlers « à quitte ou double » à Islamabad, selon l’expression employée par le premier ministre pakistanais, Shehbaz Sharif.

With multiple rovers currently scurrying around on the surface of Mars to continue a decades-long legacy, it can be easy to forget sometimes that repeating this feat on other planets that aren’t Earth or Mars isn’t quite as straightforward. In the case of Earth’s twin – Venus – the surface conditions are too extreme to consider such a mission. Yet Mercury might be a plausible target for a rover, according to a study by [M. Murillo] and [P. G. Lucey], via Universe Today’s coverage.
The advantages of putting a rover’s wheels on a planet’s surface are obvious, as it allows for direct sampling of geological and other features unlike an orbiting or...

Most rhythm games have a community creating custom charts, and Trombone Champ is no exception. What is exceptional, however, [CraftedCart]’s osu! played in a Trombone Champ chart.
It all started as a challenge to make the most unserious chart possible. Among some other ideas, [CraftedCart] eventually decides to make an osu! chart but play it in Trombone Champ. Okay, not a problem, let’s just–oh, you can’t run arbitrary code without a making a mod. So instead, they decided to use shaders on the GPU. There are, of course, all sorts of problems with such an idea. Being stuck in the fixed render pipeline of a game, you can’t just add any resources to your shader you want. This leads to using textures as...

Autopsy of Battle Born LFP battery with the ‘thermal safety’ on the bus bar. (Credit: Will Prowse)
After users of Battle Born LFP batteries encountered issues such as a heavily discolored positive terminal and other signs of overheating, multiple autopsies showed that the cause appeared to be the insertion of a thermoplastic between the bus bar and the terminal. Over time thermal creep loosened the connections, causing poor contact and melting plastic enclosures. According to Battle Born, this is actually part of an ingenious thermal safety design, and in a recently published article they explain how it works.
The basic theory appears to be that if there’s a thermal event, the ABS thermoplastic will...

Machine screws aren’t made for wood or sheet metal, they make specific screws for those applications. You probably also know there are special screws for plastic. But did you know there are at least two distinct types? In a recent video, [Lost in Tech] show us different types of plastic screws, including thermal camera shots of screws driving into 3D printed parts, along with tests using a torque driver.
We have often used “any old” screw in printed parts, which usually works OK. We’ve also used threaded inserts or captive nuts, classic choices. One of the issues with screws or inserts is that you have to get accurately sized holes in your 3D prints.
In addition to learning about the types of screws...

“A new gene therapy is giving people born deaf the chance to hear, often within just weeks. In a small but groundbreaking study, researchers delivered a working copy of a key hearing gene directly into the inner ear using a single injection. All ten patients, ranging from young children to adults, experienced improved hearing, with some showing rapid gains in just one month.” From ScienceDaily.

“Not long ago, Australia’s ampurta, also known as the crest-tailed mulgara, hung on the precipice of extinction. Now, a new study has mapped its dramatic resurgence. This small marsupial increased its range by an area the size of Denmark between 2015 and 2021, building on an ongoing re-expansion. The ampurta resurged thanks to an introduced disease that drastically reduced the population of nonnative rabbits. That led to a drop in the number of foxes and feral cats that prey on small animals, including ampurtas.” From Mongabay.

Entretien avec la sénatrice Laure Darcos (Horizons), à l'origine d'une proposition de loi qui vise à protéger les artistes du pillage de leurs œuvres par des fournisseurs d'IA, qui s'en servent pour nourrir leurs algorithmes sans égard pour les droits d'auteur.

Le Parti Populaire Européen (PPE) travaillerait très étroitement avec l'AfD, parti d'extrême droite allemand, ainsi qu'avec d'autres groupes au Parlement européen. Une enquête de l'agence de presse allemande dpa a révélé cette affaire. Dès novembre, le groupe PPE avait déjà adopté une loi avec des groupes de droite et d'extrême droite. Pourquoi cela a-t-il déclenché une telle polémique en Allemagne ? Au milieu de l'agitation bruxelloise, on aperçoit une poignée de députés qui, il y a encore quelques jours, ont élaboré en secret un projet de loi visant à expulser les demandeurs d'asile. Dans un groupe WhatsApp, des députés du PPE ont échangé avec des membres de groupes d'extrême...

xAI vient de déposer plainte devant un tribunal fédéral du Colorado pour faire annuler le SB 24-205, une loi qui doit entrer en vigueur le 30 juin prochain. Ce texte impose aux développeurs de systèmes d'IA "à haut risque" de mettre en place des garde-fous contre les discriminations algorithmiques.
Sont concernés les outils utilisés pour prendre des décisions dans l'emploi, le logement, l'éducation, la santé et les services financiers. En clair, si votre IA aide à trier des CV ou à accorder un prêt, elle doit prouver qu'elle ne discrimine personne.
Le problème pour xAI, c'est que Grok, son modèle phare, tomberait pile dans cette catégorie. L'entreprise d'Elon Musk estime que la loi...

Un groupe de chercheurs et d’artistes s'est lancé pour défi de donner vie à une pièce uchronique que Molière aurait pu écrire s’il n’était pas mort en 1673. Et ce, à l’aide de l’intelligence artificielle. À un mois de la première représentation, nous avons rencontré ce collectif dénommé Molière Ex Machina pour entrapercevoir les contours de cette œuvre sans nul pareil en France.

Pour Brigitte Stora, l’ampleur prise par la pétition contre la loi Yadan révèle moins un débat éclairé sur le texte qu’un emballement collectif nourri de déformations, d’ambiguïtés et de sous-entendus antisémites.
