This installation enables a live plant to control a machete. plant machete has a control system that reads and utilizes the electrical noises found in a live philodendron. The system uses an open source micro-controller connected to the plant to read varying resistance signals across the plant’s leaves. Using custom software, these signals are mapped in real-time to the movements of the joints of the industrial robot holding a machete. In this way, the movements of the machete are determined based on input from the plant. Essentially the plant is the brain of the robot controlling the machete determining how it swings, jabs, slices and interacts in space.
Now, you don't just go hooning any old EV around the strip, at least not if you're Ken Block. In this case, his ride is a stunning one-off electric Audi, the S1 Hoonitron, inspired by the 1987 Audi Sport quattro S1 Pikes Peak car.
Building and testing different types of Lego Pneumatic Engines that run on compressed air.
A university group named the GreenTeam, from the University of Stuttgart set the Guinness World Record for the fastest 0-62 mph (0-100 kph) electric vehicle acceleration in a 1.461-sec 0-62 mph run.
Whether they are used for powering information displays, automating testing, controlling machinery, monitoring an environment, or doing other tasks, enterprises see Raspberry Pis as serious devices for doing serious tasks. Each model has a long product lifecycle—even the older models (1B+, 2B, 3A+, 3B, and 3B+) will remain in production until at least January 2026. There is little risk that they will go obsolete, so you can maintain a sufficiently large stock and treat them as modular components that you replace rather than fix.
How can we “fingerprint” a codebase to see its structure at a glance? Let’s explore ways to automatically visualize a GitHub repo, and how that could be useful.
The crossed spikes that you see in some images of stars are not actually parts of the stars. They are imaging artifacts that are created by the telescope itself and are called diffraction spikes. Certain telescopes have a large primary mirror that focuses the incoming beam of light onto a secondary mirror or a sensor that is held over the primary mirror. The secondary mirror diverts the light out of the telescope so it can be seen or further processed. Or, alternately, a sensor held above the primary mirror converts the image to an electrical signal that is delivered to a computer.

At a macro level, you learn programming concepts that are largely transferable regardless of language. The syntax may differ, but the core ideas are still the same. This can include things like: data-structures (arrays, objects, modules, hashes), algorithms (searching, sorting), architecture (design patterns, state management) and even performance optimizations (e.g. eager vs lazy evaluation, memoization, caching, lazy-loading etc). These are concepts you’ll use so frequently that knowing them backwards can have a lot of value.
Manton Reece and Brent Simmons — have noticed that JSON has become the developers’ choice for APIs, and that developers will often go out of their way to avoid XML. JSON is simpler to read and write, and it’s less prone to bugs.

By doing open source contributions, you will learn a lot. It allows you to become a part of the open-source community. It can be hard at the beginning, but it’s definitely worth it.
GitHub uses a syntax called Markdown to format text. As many Python folks use GitHub, here’s a handy reference to how Markdown encodes the typical document formats including bold/italic/lists and much more – Twitter (open for full two page reference).
