Second IC
In 2018 I made the first lithographically fabricated integrated circuits in my garage fab. I was a senior in high school when I made the Z1 amplifier, and now I’m a senior in college so there are some long overdue improvements to the amateur silicon process. The Z1 had 6 transistors and was a great test chip to…

A Motion-Sensing Keyboard
We present a new type of augmented mechanical keyboard, sensing rich and expressive motion gestures performed both on and directly above the device. A low-resolution matrix of infrared (IR) proximity sensors is interspersed with the keys of a regular mechanical keyboard. This results in coarse but high frame-rate…

Setting up Starlink
In March, I got an email from SpaceX saying Starlink was available at my address, and I could pre-order. I paid $500 for the equipment, plus $25 for a Volcano Roof Mount, and $99 for the first month of service, and a few weeks later, I got the kit you see in the image above. I was a little too excited about getting…

Zen 2 Missives – AMD now delivering efficiencies that are double that of Intel
After languishing through the CPU dark-ages (read: Intel trying real hard to keep people on 4 cores so they could charge an arm and a leg for more), the last two years has seen a vertible tsunami of advances in CPU technologies. AMD's introduction of an 8-core CPU (the 1700X) began the rat-race and with both AMD and…

The blog of Tyler Ward (aka scorpia)2019401 points300 commentscited by 3Hardware & Electronics details
The new pi has been released and it has a USB Type-C connector for power however people are finding some chargers are not working with it (notably macbook chargers). Some have speculated that this is due to a manufacturer limitation on the power supplies however it is actually due to the incorrect detection circuitry…

On Hacking MicroSD Cards
Today at the Chaos Computer Congress ( 30C3 ), xobs and I disclosed a finding that some SD cards contain vulnerabilities that allow arbitrary code execution — on the memory card itself. On the dark side, code execution on the memory card enables a class of MITM (man-in-the-middle) attacks, where the card seems to be…

It's hard to justify buying a Framework 12
My nephew just graduated high school, and wants a laptop. When he decides what computer to buy, price (or more precisely, value) is the most important attribute. Apple's MacBook Neo upended the 'value laptop' equation—Apple's not supposed to be both the cheapest option and the best value... but it seems like that's…

Don't use Linksys routers
Back in 2012 I gave a talk at a conference titled Blended Threats and JavaScript . I demonstrated how anybody could design an internet worm that targeted common network devices like routers and turn them into a powerful botnet that is able to monitor traffic across all types of networks. For the pr
