German madman’s fully automatic crossbow will have you laughing maniacally

Add as a preferred source on Google

You can keep your fashion-obsessed vloggers, your fake “pranks,” and your boring unboxing videos, the YouTuber that has our attention is DIY slingshot maker Jörg Sprave. Hailing from Germany, Sprave has created a plethora of envy-inducing homemade “launchers” over the years — ranging from a steampunk pistol to a machine which propels bowling balls at a frankly terrifying speed.

His latest creation? A fully automatic crossbow, brought to life by way of a cordless drill and impressive gear mechanism to rapid-fire bolts just like a machine gun. To this, Sprave has now added removable magazines — with the result being one of the greatest things we’ve seen on YouTube in ages.

“I’ve been running my channel now for eight years and I always wanted to have a full auto slingshot,” Sprave told Digital Trends. “I wanted something that could do rat-a-rat rat-a-tat fire, rather than single shot, but it wasn’t easy to do. I made several attempts that weren’t successful before I got here. I think this is my best creation so far.”

Since building his rapid-fire beast, Sprave — who doesn’t use the weapons to hunt — said that he has been utilizing it to carry out target practice. “The nice thing about it is that you can reuse the bolts after you’ve fired them,” he continued. “It’s a joy to fire. It’s like shooting a solid stream of crossbow bolts. Aiming is like spraying water from a garden hose.”

Unsurprisingly, Sprave’s YouTube channel has been a hit. His videos routinely rack up hundreds of thousands of views, and his subscriber count is climbing ever northwards. His explanation?

“My channel has three things I think that people find attractive,” he said. “That is stunts, construction, and destruction. I love building things and I love destruction, particularly when it’s filmed at high speed. Destroying things can have a strong aesthetic look, which I think attracts a lot of users.”

Who would dare disagree?

The Apple Car may be dead, but it became the foundation of Apple Intelligence
A decade of work on a canceled car project reportedly laid the groundwork for Apple Intelligence.
Apple Intelligence in Apple Car

The Apple Car may have never left the garage, but it apparently gave birth to Apple's AI ambitions. According to Bloomberg's Mark Gurman, Apple's canceled autonomous vehicle project, one that consumed more than a decade of work and over $10 billion before being scrapped in 2024, ended up laying the technological foundation for Apple Intelligence. In a rather ironic twist, one of Apple's most expensive failures may also become one of its most important long-term investments.

Researchers hid a prompt injection inside a PNG, and AI fell for it

AI coding assistants like Claude are becoming every developer's favorite coworker. They can review code, explain confusing functions, and even write entire features with a single prompt. But new research suggests that this growing trust could also become their biggest weakness.

A team of security researchers (professor Sudipta Chattopadhyay and researcher Murali Ediga) has demonstrated an unusual attack that doesn't target the AI model directly. Instead, it targets what the AI doesn't pay enough attention to during code reviews. Rather than hiding malicious instructions in lines of code, the researchers tucked them inside an image file. Since many AI review tools treat images as decorative assets rather than as something worth inspecting, the pull request can appear perfectly harmless and sail through the review.

AI has already fallen into the wrong hands and they’re using it to make bombs

Artificial intelligence has quickly become the go-to tool for everything from writing emails and summarizing meetings to helping students study or developers debug code. But the same technology that saves people time can also be misused, and a new report suggests that terrorist organizations are finding ways to do exactly that.

According to a research paper shared with The New York Times ahead of its publication, researchers found evidence that members of Boko Haram have been using popular AI chatbots to support both day-to-day activities and combat-related tasks. Interviews with 27 former members conducted in Nigeria over the past two years suggest that tools such as ChatGPT, Gemini, Claude, Grok, Meta AI, and DeepSeek were used to gather technical information, troubleshoot weapons, and even assist with planning attacks.
