pwn.college is an education platform for students (and other interested parties) to learn about, and practice, core cybersecurity concepts in a hands-on fashion. In martial arts terms, it is designed to take a “white belt” in cybersecurity through the journey to becoming a “blue belt”, able to approach (simple) cybersecurity competitions (CTFs) and wargames.

Electronics-based art installations are often fleeting and specific things that only a select few people who are in the right place or time get to experience before they are lost to the ravages of ‘progress.’ So it’s wonderful to find a dedicated son who has recreated his father’s 1973 art installation, showing it to the world in a miniature form. The network-iv-rebooted project is a recreation of an installation once housed within a departure lounge in terminal C of Seattle-Tacoma airport.

TL;DR - A simple mission to write a guide for some people on Reddit on how to create a plane spotting screen led me down a deep ADS-B rabbit hole and ended with me building a clock.

Read on for a guide to build a screen yourself (GitHub repo here), or if you can't be bothered to source the components and run your own ADS-B station, I can send you a kit with everything you need to set up a clock like the one above.

Encore peu connu du grand public, le logiciel Obsidian obsède des millions d’internautes : c’est l’outil le plus populaire pour se créer un « second cerveau » via la prise de notes. Notre journaliste s’est essayée à cette extension numérique pleine de promesses… et de zones d’ombres. Elle nous raconte.

Are you also afraid that your plants might die when you go on vacation? Me too! Now I have finally solved this problem for good!

In this video I'm transforming my prototype of an automated watering system into a final product in a beautiful packaging. It's been somewhat of a long process and I ended up spending much more time on this, than I had planned on. But I definitely think it was worth it! Do you?

Enjoy!

MuJoCo stands for Multi-Joint dynamics with Contact. It is a general purpose physics engine that aims to facilitate research and development in robotics, biomechanics, graphics and animation, machine learning, and other areas that demand fast and accurate simulation of articulated structures interacting with their environment. Initially developed by Roboti LLC, it was acquired and made freely available by DeepMind in October 2021, and open sourced in May 2022. The MuJoCo codebase is available at the google-deepmind/mujoco repository on GitHub.

Jooki was a dream come true for parents—an intuitive, screen-free audio player that let kids enjoy music and stories with the tap of a token. But that dream turned into frustration when the company behind Jooki went bankrupt, leaving countless devices bricked and families frustrated. But what if Jooki isn’t as dead as it seems?

This blog post isn’t just about fixing a broken audio player—it’s about peeling back the layers of its firmware, finding hidden exploits, a backdoor and unlocking code execution.

We recently got a note in the tips line from [Tavis Gustafson], who is one of the developers of Tronbyt — a replacement firmware and self-hosted backend that breaks the Tidbyt smart display free from its cloud dependency. When they started the project, [Tavis] says the intent was simply to let privacy-minded users keep their data within the local network, which was itself a goal worthy enough to be featured on these pages.

We were thinking about the first such bot we’ve ever seen, and couldn’t come up with anything earlier than Hektor, a spray-painting version of this idea by [Juerg Lehni]. And since then, it’s reappeared in numerous variations.

Details on how we organised thousands of tracks to build a music discovery service that lets you find your next favourite song from BBC Introducing acts.

For map-lovers like [Christopher Getschmann], poring over a quality map can be as satisfying as reading a good book. Good maps can be hard to come by, though, especially at a scale worth looking at, or worth using as adornment on a dull, lifeless wall. The solution is obvious: build a wall-mount CNC plotter to draw maps directly on the wall.
