GRC SpinRite
I feel like I used to spend an inordinate amount of time dealing with suspect hard drives. I mean, like, back in high school. These days I almost never do, or on the occasion that I have storage trouble, it's a drive that has completely stopped responding at all and there's little to do besides replacing it. One time…

A Year of 3D Printing
If you'd asked me a few years back if I thought I'd buy a 3D printer, I would have said no. My experience of 3D printers back when I was in college was that they were very slow, expensive, frequently failed mid-print, and needed constant calibration...

MiniDisc Hacking
Most MiniDisc aficionados are aware of unit hacking to gain access to new features. The unit that perhaps benefits the most from this is the Sony MZ-N510, which also comes in the N520 and NF610 variants. The 2001 model R700 can be hacked to add many features of its upscale brother, the R900 , as well as the Type-R…

Conway's Game of Life on FPGA
When learning a new programming language, I like having a well defined yet non-trivial problem to solve. Conway’s Game of Life (GoL) fits this definition. It has enough depth to uncover various tradeoffs. So naturally, when I picked up Chisel hardware description language (HDL), I wanted to build Game of Life in FPGA…

Infra-Red, in Situ (Iris) Inspection of Silicon
Cryptography tells us how to make a chain of trust rooted in special-purpose chips known as secure elements. But how do we come to trust our secure elements? I have been searching for solutions to this thorny supply chain problem . Ideally, one can directly inspect the construction of a chip, but any viable inspection…

IPad 2 introduces new headphone jack
Update: Just to clarify, this post is speculation, not fact. Based on the excellent iFixit teardowns it looks like the iPad 2 headphone jack has pins on both sides , which is more in line with Apple's typical cantilever design (roughly similar to the jack in the Macbook Air ). Interestingly, it looks like the…
