Of Roach Killer and Rust Remover: Sam Zeloof’s Garage-Made Chips
A normal life in hacking, if there is such a thing, seems to follow a predictable trajectory, at least in terms of the physical space it occupies. We generally start small, working on a few simple projects on the kitchen table, or if we start young enough, perhaps on a desk in our childhood bedroom. Time passes, our skills increase, and with them the need for space. Soon we’re claiming an unused room or a corner of the basement. Skills build on skills, gear accumulates, and before you know it, the garage is no longer a place for cars but …read more
How the Xbox Was Hacked
The millennium: a term that few had any use for before 1999, yet seemingly overnight it was everywhere. The turning of the millenium permeated every facet of pop culture. Unconventional popstars like Moby supplied electronica to the mainstream airwaves while audiences contemplated whether computers were the true enemy after seeing The Matrix. We were torn between anxiety — the impending Y2K bug bringing the end of civilization that Prince prophesied — and anticipation: the forthcoming release of the PlayStation 2.
Sony was poised to take control of the videogame console market once again. They had already sold more …read more
Hack My House: Opening Raspberry Pi to the Internet, but Not the Whole World
If you’ve followed along with our series so far, you know we’ve set up a network of Raspberry Pis that PXE boot off a central server, and then used Zoneminder to run a network of IP cameras. Now that some useful services are running in our smart house, how do we access those services when away from home, and how do we keep the rest of the world from spying on our cameras?
Before we get to VPNs and port forwarding, there is a more fundamental issue: Do you trust your devices? What exactly is the firmware on those cheap …read more
Mechanisms: Lead Screws and Ball Screws
Translating rotary motion to linear motion is a basic part of mechatronic design. Take a look at the nearest 3D-printer or CNC router — at least the Cartesian variety — and you’ll see some mechanism that converts the rotation of the the motor shafts into the smooth linear motion needed for each axis.
Hobby-grade machines are as likely as not to use pulleys and timing belts to achieve this translation, and that generally meets the needs of the machine. But in some machines, the stretchiness of a belt won’t cut it, and the designer may turn to some variety of …read more
Alice Evans: Brucellosis, or Why We Pasteurize Milk
It’s easy to forget how much illness and death was caused by our food and drink just one hundred years ago. Our modern food systems, backed by sound research and decent regulation, have elevated food safety to the point where outbreaks of illness are big news. If you get sick from a burger, or a nice tall glass of milk, it’s no longer a mystery what happened. Instead we ask why, and “who screwed up?”
In the early 20th century though, many food-borne illnesses were still a mystery, and microbiology was a scientific endeavor that was just getting started. Alice …read more
