Lessons from Running a Small-Scale Electronics Factory in My Guest Bedroom
After assembling over 200 Telephreak badges by hand for DEFCON 26 (and taking *way* longer to accomplish it than I estimated) I figured I should document some of the lessons that I learned along the way – from initial design to finished product. The subject of many of the examples of the right way to […]

AirPods get stuck in low-quality 16 kHz audio mode when starting a VM
I always love when I find a really dumb solution that works reliably to fix a problem that should never really be a problem in the first place. But having worked with audio devices before—though nothing nearly as complex as the AirPods—I am willing to cut Apple some slack in building a seamless aural experience with…

Why I'm usually unnerved when modern SSDs die on us
You're probably reading this page because you've attempted to access some part of my blog (Wandering Thoughts) or CSpace , the wiki thing it's part of. Unfortunately you're using a browser version that my anti-crawler precautions consider suspicious, most often because it's too old (most often this applies to versions…

Do I really need to get out the soldering-iron again?
So I had this idea that it would be nice to listen to music when I get home from work everyday, so I put all my ripped music onto my phone, and I bought some good quality over-ear headphones.

Designing and building an FPGA sprite-based graphics accelerator (2014)
A very warm welcome to my most ambitious project to date. In this project I’m going to attempt to design and build a sprite-based graphics accelerator that will function as a co-processor to an MCU. Using cheap off-the-shelf components I’m hoping to achieve a level of gaming performance that compares well to popular…

Fast line-following robots
Since February 2016, I have been participating in DIYRobocars meetups here in the SF Bay Area, wherein a bunch of amateur roboticists compete in autonomous time trials with RC cars. I had been doing very well in the competition with essentially just a glorified line-following robot, but have lately upgraded to a full…

Memory-Level Parallelism: Intel Skylake versus Apple A12/A12X
Modern processors execute instructions in parallel in many different ways: multi-core parallelism is just one of them. In particular, processor cores can have several outstanding memory access requests "in flight". This is often described as "memory-level parallelism". You can measure the level of memory-level…
