Adversarial IR Hoodie Lets You Own The Night In Anonymity

March 6, 2023 by Dan Maloney 75 Comments

If you’re in the market for something to obfuscate your nefarious nocturnal activities, rejoice — this adversarial infrared hoodie may be just what you’re looking for.

Not that we condone illegal activities, of course, and neither does artist [Mac Pierce], who created “The Camera-Shy Hoodie.” His purpose seems to be exploring the nature of the surveillance state, or rather to perplex it in the name of anonymity. The idea is simple — equip a standard hoodie with a ring of super-bright IR LEDs, and control them with an RP2040.

We’ve seen blinding hoodies before, but here the LEDs strobe on and off in one of three different patterns, all of which are timed to confound the autoexposure mechanism in just about any surveillance camera by not giving it time to adjust to the rapidly and drastically changing light level. The result is near-total obfuscation of the wearer’s facial features, at least when the camera is in night-vision mode. Check out the results in the video below.

There are some nice touches to [Mac]’s approach, like aluminum PCBs for the LEDs and the use of soldered-on fabric snaps to attach them to the inside of the hoodie, making them easy to remove for laundering. With the LEDs peeking through holes in the fabric, the hoodie looks pretty run-of-the-mill — until, of course, night falls and the USB battery bank in the hoodie’s pocket powers up the light show.

Granted, this won’t exactly help you avoid detection — the big ball of light around your head will be instantly seen by even the most casual observer. But at least it makes it easier to keep your face to yourself. And it won’t help much in daylight — for that, you might want something a little more like this passive adversarial ugly sweater.

Clean Air And A Gentle Breeze In Your Hoodie

March 5, 2020 by Sven Gregori 18 Comments

Hoodies are great, and rightfully a hacker’s favorite attire: they shield you from the people around you, keep your focus on the screen in front of you, and are a decent enough backup solution when you forgot your balaclava. More than that, they are also comfortable, unless of course it is summer time. But don’t worry, [elkroketto] has built a solution to provide the regular hoodie wearer with a constant breeze around his face, although his Clean Air Bubble is primarily tackling an even bigger problem: air pollution.

Wanting to block out any environmental factors from the air he breathes, [elkroketto] got himself a thrift store hoodie to cut holes in the back, and attach two radial fans that suck in the air through air filtering cloths. A 3D printed air channel is then connected to each fan, and attached on the inside of the hood, blowing the filtered air straight into his face. Salvaging a broken drill’s battery pack as power supply and adding a 3D printed clip-in case for the step-up converter, the fans should provide him a good 5 hours of fresh air. Of course, one could also add a solar charging rig if that’s not enough.

Keep in mind though, while a wearable air filter might sound particularly useful in current times, [elkroketto] specifically points out that this is not for medical use and won’t filter out any airborne diseases.

Dinosaur Hoodie To Remind You Halloween Approaches!!

September 14, 2012 by Mike Szczys 3 Comments

[Tom’s] dinosaur hoodie would make a bang up Halloween costume. It’s a glowing version of the bony plates you’d find on a Stegosaurus. Not only does it look great at night, you should be able to put one together or yourself in an afternoon.

He used a laser cutter to make the translucent fins, but it would not be hard to cut them all out by hand. Each piece is two sides of the plate connected by a narrow rectangle which leaves room inside for an RGB module. These are chained together and controlled by an Arduino (most likely using SPI or I2C, we’re not sure which), then sewn on the back of a hoodie.

Update: [Matt] made a derivative of this design. The plates are pointy like a stegosaurus.

Send in those Halloween projects

Which reminds us… Halloween quickly approaches and we haven’t seen the usual onslaught of awesome. We love this time of year because of the ingenuity that comes out to play in the costumes, yard decor, and scare tactics being prepared for the big night. Please send a link to your project and we’ll start pumping out the holiday features.

To get you thinking, here’s a set of folding wings used in a costume, and a possessed powerwheels to chase down the little ones. Don’t sit on your hands, we want to hear about every project!

Reboot Life In A Heartbeat

February 18, 2010 by Mike Szczys 18 Comments

This hoodie senses your heartbeat and uses it to control Life. Conway’s Game of Life, popular in all kinds of electronics projects, uses a grid of cells coupled with a set of rules to mimic the life and death of simple organisms. This iteration displays the game over your own heart, then taps into your heart rate, resetting the game at the beginning of each cardiac cycle. We guess you could say that Life goes on only if you do not.

The EKG circuit that detects the heartbeat is made up of an IR transmitter shining through the tip of your finger to a receiver. An ATmega168 running the Arduino bootloader controls the EKG circuit and resets an ATmega48 which is responsible for Life. [Joe] admits that this is overkill but he’s currently without an AVR programmer; he went this route to make it work. The stylishly-geeky hoodie is taken for a test run (er… test-hop?) after the break.

Anonymizing Clothing

June 17, 2008 by Juan Aguilar 8 Comments

Though much of [citizenFinerran]’s intent in designing a suit that camouflages the wearer from security camera footage was philosophical, it is designed with a very tangible purpose in mind. The suit does not provide true camouflage (to say nothing of true invisibility), but it does create enough moving visual obstructions to make the wearer completely anonymous on film. More details on this and other invisibility cloaks after the break.
