MIT students create and circulate open source, covert RFID rings to subvert campus tracking system

A reader writes, "A couple years ago MIT changed their dorm security/student tracking policy. They hired security contractors to work in dorms and required everyone to tap their RFID cards upon entry (no vouching for friends/guests). Most students complied. Some moved out. Some got in trouble ;)" Read the rest

Creepy new spy camera is so small it could be hiding anywhere

If you're not already wearing a tinfoil hat, it may be a good time to start: a pair of engineers based out of the University of Michigan have figured out a way to create a light-powered camera sensor that's only a millimeter in size: small enough to be practically invisible to a casual observer.

According to a paper published in IEEE Electron Device Letters by Euisik Yoon and Sung-Yun Park, the new camera has the potential to not only be insanely small, but also, self sustaining, thanks to a solar panel placed directly behind the camera's image sensor, which is thin enough that light, in addition to what's needed to create an image, is able to pass right through it. This could provide the camera with all the power it needs to be able to continue to capture images, indefinitely.  At a maximum of 15 frames per second, the images it captures aren't of the best quality, but they're more than adequate for creeping on an unsuspecting subject.

The good news is that, for the time being, the camera is nothing more than a proof-of-concept. In order for it to be deployed in the real world as a near-invisible surveillance device, someone a lot smarter than me will need to figure out how to store image data and transmit it using hardware that's just as discrete as the camera's image sensor and power source are.

Fingers crossed that it'll take them a while to work those issues out.   Image via pxhere Read the rest

This is the best NSFW explanation of the Florida bridge collapse

Aerial footage of a Volkswagen diesel car graveyard in California

To date, Volkswagen has bought back about 350,000 diesel vehicles in the wake of the massive environmental fraud they committed around emissions testing. Here's one of 37 VW graveyards. Read the rest

Watch military swarm drones lock on and surround a target

Autonomous weapon bans (previously) are currently being debated, but in the meantime, the US Department of Defense continues work with its Perdix Micro-Drone project. Ostensibly for surveillance, it's clear these could easily be modded with lethal weaponry. Read the rest

Massive cruise ship sliced in half to embiggen it

Silversea Cruises has sliced their massive Silversea ship in half so that they can inset a 15 meter (50 feet) extension and increase the ship's capacity by 15 percent. While this kind of thing is commonly done to convert regular automobiles into stretch limos, the company describes this undertaking as a "rarely performed feat of maritime architecture." From CNN:

The elaborate engineering feat, underway at the Fincantieri Shipyard in Palermo, Italy, requires over 500 skilled workers and will take up approximately 450,000 man hours.

A prebuilt 15-meter extension (almost 50 feet) has already been inserted with "military precision" to stretch Silver Spirit from 195.8 to 210.7 meters.

This 1936 film celebrates maker culture (boys only, please)

The 1936 All-American Soap Box Derby is a fascinating look at the ethos and mores from the height of the soap box derby craze. While it's cool to see maker culture valued and celebrated, it's certainly not very inclusive. Read the rest

Adorable child interrupts YouTube review of mechanical component

Jump straight to 4:30 in this otherwise riveting examination of a fixed-displacement oil pump, posted by AvE. My favorite part is when the kid analogizes the pump's pentalobe shape to screws rather than flowers. Engineers! Read the rest

The astounding science and engineering of printer jams

Anil Dash's third law holds that "Three things never work: Voice chat, printers and projectors." But Joshua Rothman's long, fascinating, even poetic profile of the Xerox engineers who work on paper-path process improvements is such a bit of hard-science whimsy that it almost makes me forgive every hour I've spent swearing over jammed paper.
