TEMPEST attacks are often the most effective way to break air-gapped security: rather than directly accessing a computer, the attacker records the system’s unintended radio emissions and uses them to …read more Continue reading Reviving TEMPEST Attacks with an Injected Signal
Although it wasn’t apparently designed with this in mind, it seems particularly fortuitous that this walking robotic hand was released in time for Halloween. Designed by researchers from ETH Zurich, …read more Continue reading Teaching a Robot Hand to Walk
Clocks are almost the ideal devices to inspire creativity in hackers — they have a simple, well-defined task, but there’s an almost unlimited number of ways to carry it out. …read more Continue reading Keeping Time on Tumbling Icosahedra
We tend to think of breaking the sound barrier as a comparatively modern accomplishment, but on a smaller scale, cattle herders have been breaking it for centuries: the cracking sound …read more Continue reading Whip-Cracking Machine Reliably Breaks the Sound Barrier
Resin 3D printing has opened up a whole new scale of resolution for hackers, but the technology can go still finer; commercial micro-SLA and two-photon polymerization printers can print items …read more Continue reading Printing Micron-Scale Benchies With Resin and Turmeric
Driven by a desire for privacy, customization, and lower costs, there’s growing interest in AI models which can be run on local hardware. Few of them go as far as …read more Continue reading Running Generative AI on an RP2350
If you want improve a model rocket’s performance, all the common options come with serious trade-offs: you could increase the motor’s size, which raises safety issues, or you could cut …read more Continue reading Tube Launch Boosts Rocket’s Performance
[soiboi soft]’s vacuum-driven dot matrix display is part suction gripper, part touchscreen, and altogether impressive. Its display capabilities are entirely shadow-based, with each pixel being made of a cavity behind …read more Continue reading Playing Snake with a Pneumatic Display
There’s plenty of substances that can theoretically be extruded from a nozzle, but only a regrettably small subset of them can actually be used for 3D printing. One limiting factor …read more Continue reading Support Bath Enables an Epoxy Benchy
Impressive as it most certainly is when an amateur fabricates a semiconductor, most of the projects we’ve seen are more demonstrations than workable chips. [Dr. Semiconductor], however, is going much …read more Continue reading Making LEDs in the Home Fab
