Using IR LEDs To Hide In Plain Sight

Getting by without falling under the gaze of surveillance cameras doesn’t seem possible nowadays – from malls to street corners, it’s getting more common for organizations to use surveillance cameras to keep patrons in check. While the freedom of assembly is considered a basic human right in documents such as the US Condition and the […]

Exploring Early ’90s Video Game Architecture With Another World

Curious about past computer architectures? Software engineer [Fabien Sanglard] has been experimenting with porting Another World, an action-adventure platformer, to different machines and comparing the results in his “Polygons of Another World” project. The results are pretty interesting. Due to the game’s polygon-based graphics, optimizations vary widely across different architectures, with tricks allowing the software […]

A Safer, Self-Healing Polymer Battery

Lithium-ion batteries are notorious for spontaneously combusting, with seemingly so many ways that it can be triggered. While they are a compact and relatively affordable rechargeable battery for hobbyists, damage to the batteries can be dangerous and lead to fires. Several engineers from the University of Illinois have developed a solid polymer-based electrolyte that is […]

Particle Accelerators That Fit on a Chip

If you were asked to imagine a particle accelerator, you would probably picture a high-energy electron beam contained within a kilometers-long facility, manned by hundreds of engineers and researchers. You probably wouldn’t think of a chip smaller than a fingernail, yet that’s exactly what the SLAC National Accelerator Laboratory’s Accelerator on a Chip International Program […]

This Artist Drags His Feet Across Sand and Snow

You may have seen Simon Beck’s work a few years back. The snow artist, known for creating large-scale works of art with nothing but snowshoes, has been creating geometrically inspired fractals and mathematical forms for years. An orienteer and map-maker by day, he typically plans out his works in advance and chooses sites based on […]
