Hacking And Philosophy: The Mentor’s Manifesto

hnpMentorsManifesto

Welcome back to Hacking & Philosophy! I’ve done my best to keep up with the comments from last week’s article, and your responses and suggestions have been invaluable. Most readers expressed concern over how this column would define “hacker” or “hacking,” and whether the texts focused more on hacking-as-illegal or the hacker/maker culture. Rest assured that all interpretations are welcome, but I have no intention of dwelling on the sensationalized, criminal hacker stereotype, either. Others asked whether we’d be holding our conversation somewhere a bit more user-friendly: a solution is in the works. For now, we will stick to the comments.

Last week, I asked you to read an early document in hacking history: The Mentor’s “A Hacker Manifesto,” also called “The Conscience of a Hacker.” What follows is my analysis of the essay. I invite you to join me in a discussion in the comments: post your responses to the piece, your questions, your objections, anything! Now, lets take a trip back to the 80’s…

RFID Reader Snoops Cards From 3 Feet Away

Security researcher [Fran Brown] sent us this tip about his Tastic RFID Thief, which can stealthily snag the information off an RFID card at long range. If you’ve worked with passive RFID before, you know that most readers only work within inches of the card. In [Fran’s] DEFCON talk this summer he calls it the “ass-grabbing method” of trying to get a hidden antenna close enough to a target’s wallet.

His solution takes an off-the-shelf high-powered reader, (such as the HID MaxiProx 5375), and makes it amazingly portable by embedding 12 AA batteries and a custom PCB using an Arduino Nano to interpret the reader’s output. When the reader sees a nearby card, the information is parsed through the Nano and the data is both sent to an LCD screen and stored to a .txt file on a removable microSD card for later retrieval.

There are two short videos after the break: a demonstration of the Tastic RFID Thief and a quick look at its guts. If you’re considering reproducing this tool and you’re picking your jaw off the floor over the price of the reader, you can always try building your own…

Video Game Automation Hacks

coupleofvideogamehacks

3rd party console game controllers sometimes sport a “rapid-fire” button to give gamers an unfair advantage. [Connor’s] project is along the same lines, but his hack had a different goal: automate the input of GTA5 cheat codes. [Connor] admits that this is his first Arduino hack, but aside from a small hiccup, he managed to pull it off. The build connects each button on a PS3 controller via some ribbon cable to its own digital out on an Arduino Uno . After plugging in some pretty straightforward code, [Connor] can simply press one button to automate a lengthy cheat code process.

[Matt’s] hack manages to save him even more user input in this second video game hack, which automates finger clicks in an Android game. [Matt] pieced together a couple of servos plugged into a PICAXE-18M2 microcontroller, which repeats one simple action in [Matt’s] Sims Freeplay game: continuously “freshening” (flushing?) a toilet. To mimic the same capacitive response of two fingers, [Matt] built the two contact surfaces out of some anti-static foam, then grounded them out with a wire to the ground on the board.

Check out a gallery of [Connor’s] controller and a video of [Matt’s] tablet hack after the break, then check out a rapid fire controller hack that attacks an XBox360 controller.

A Killer Arcade Cabinet For Halloween

slaughterhouseArcade

It’s already pretty cool that [Clay] co-owns an Arcade, but he’s really impressed us with his custom-made Splatterhouse cabinet built to get his patrons in the Halloween spirit! A Namco brawler title from 1988, Splatterhouse came in an unadorned and otherwise forgettable cabinet. [Clay] salvaged an old Williams Defender, coating the sides with a cocktail of drywall compound, sand, and paint to achieve a stone texture. He then carved up some pink insulation foam into a tattered “wooden” frame and used it as a monitor bezel. For accents, he fashioned strips of latex to resemble torn flesh and placed them among the boards. The control panel is yet another work of art: [Clay] 3D printed a life-size human femur for the game’s joystick, and converted the buttons to look like eyeballs.

[Clay] decided to go beyond the stunning cosmetics, though, and tapped into the game’s CPU with a custom daughterboard that detects different in-game events and state changes such as player health. An ATMega165 uses four PWM outputs connected to a number of LEDs inside the cabinet and around the monitor bezel to react to the different events. If a player takes damage, red lights flash around the monitor. Inserting a coin or dying in the game causes a different set of LEDs behind the marquee to go nuts.

Check out his detailed project page for more information and see a video overview below. If building a full-scale arcade machine is out of your budget, you can always make a tiny one.

Bicycle Generator For Emergency Electricity

hackettBikeGenerator

[Hackett’s] back at it, this time with some practical advice for the next power outage to hit your city: why not prepare for the worst by building your own bike generator? You’ll no doubt recall that hurricane Sandy devastated New York City’s grid, even flooding substations and causing massive explosions. [Hackett] experienced the Sandy outages first-hand, and knows the value of having this simple build ready to roll.

The project uses a permanent magnet DC motor (around 250 watts), which you can find in electric wheelchairs or other mobility scooters. His setup’s gear reduction spins the motor 50 times for each revolution of the bike wheel. The apparatus [Hackett] built to press-fit the wheel to the motor’s spindle is particularly clever: a threaded rod adjusts the position of the motor, which is bolted onto a hinged platform, with the other part of the hinge welded to a larger frame that supports the bike wheel.

The motor is connected to a home-built charge controller based on Mike Davis’s design, which monitors the deep-cycle batteries and both kills the charge when it’s full as well as turns charging back on after it’s reached a set level of discharge. The rest is gravy: with the deep cycle battery connected to a power inverter, [Hackett] can plug in and keep phones charged, music playing, and even (some of) the lights on. If you’re a fan of [Hackett’s] straightforward, practical presentation style, check out his tripod build and his demonstration of stripping pipes of their galvanization.

Ask Hackaday: Does Project Ara Solve The Phonebloks’ Problems?

Our tips line is blowing up again, this time directing us to Motorola’s Project Ara: a phone with modular components that plug into a base “endoskeleton.” If you missed the news coverage strewn across the web and you are doing a double-take, that’s because Project Ara is frighteningly similar to the (presumed vaporware) Phonebloks concept from a few weeks ago. Phonebloks was the subject of our last “Ask Hackaday” article, generating hundreds of comments ranging from those defending the concept to those furiously opposed to it.

There’s a conspiracy theory circulating that suggests Motorola released the Phonebloks concept as a viral marketing scheme to generate hype before revealing the official product line. We suspect it’s a bit less conniving. As [jorde] explained on Hacker News, an Israeli startup, Modu, had developed a similar modular cell phone several years ago, and Google bought the patents in May of 2011. A few months later, Google bought something else: Motorola. It seems likely that Project Ara is merely a resurrected and revised Modu, and Motorola conveniently announced it in the wake of Phonebloks’ popularity. Regardless, Motorola has announced that they have partnered with Phonebloks’ creator Dave Hakkens .

So what’s different? Phonebloks was met with cries of “vaporware!” and fervent arguments raising concerns about unavoidable hardware limitations. Motorola claims their goal is:

to do for hardware what the Android platform has done for software: create a vibrant third-party developer ecosystem, lower the barriers to entry, increase the pace of innovation, and substantially compress development timelines.

Unlike Project Ara, Phonebloks didn’t consider open-source hardware (Wayback Machine link), and Motorola makes an interesting argument here: that advances in 3D printing indicate an evolving “open hardware ecosystem,” and the next era of phone development may rest in the hands of your average hacker or a small startup company. Some speculate that the Ara will be similar to the relationship between a PC and its peripherals: Motorola provides the essential guts while giving you some slots for attaching additional components. Let us know in the comments what you think about Project Ara: is it just more vaporware, or a watered-down but plausible alternative to Phonebloks?  And, perhaps most important: do you, as a hacker, want a phone that supports open hardware and lets you plug in “peripherals?” The Phonebloks website has since changed to reflect the partnership with Motorola, and includes a new video that you can watch below.

Retrotechtacular: Automata

automatonWriter

For a moment, suspend your worldview and adopt Descartes’s mechanistic interpretation that living beings are essentially complex machines: a collection of inherently unrelated parts that move and collide. Automata, then, represented the pinnacle of accomplishment in a mechanistic universe, requiring considerable skill to construct. Most of their inventors, such as Pierre Jaquet-Droz, were clockmakers or watchmakers, and automata like the 240-year-old boy writer are packed with moving parts to automate motion.

Jaquet-Droz’s writer is particularly impressive considering all its moving parts—nearly six thousand of them—fit entirely within the boy’s body, and that one can “program” the text that the boy composes. It may sound like a bit of a stretch to claim that these clockwork amusements were precursors to the computer, but they influenced inventors and engineers for centuries.

You’ve likely heard of the other famous automaton: The Turk, (which was actually a hoax, housing an operator inside its base). The Turk, however, managed to inspire Charles Babbage to pursue building a mechanical device capable of performing mathematical functions: the Difference Engine.

Watch some of Jaquet-Droz’s other clockwork masterpieces in a video after the break. Magicians like Robert-Houdin were responsible for building a number of automata, so we recommend you keep the mystical atmosphere flowing by checking out another magician’s performance oddities.
