Formlabs Form 4 Teardown
Formlabs has recently launched the fourth edition of their flagship SLA printer line, the Form 4 . Of course, I jumped on the chance to do a teardown of the printer; I’m grateful that I was able to do the same for the Form 1 , Form 2 , and Form 3 generations. In addition to learning a lot from the process of tearing…

Galois field instructions on 2021 CPUs
CPUs like to operate on data types such as uint8_t , uint16_t , uint32_t , and uint64_t . These data types can be viewed as integers modulo 2 8 , 2 16 , 2 32 , and 2 64 respectively. Addition and multiplication can be defined on these integers modulo 2 N in a way which is familiar to most people; for example, in…

Creating an autopilot in X-Plane using Python
Introduction Today’s post will take us in a slightly different direction than the last few. Today’s post will be about hooking up some Python code to the X-Plane flight simulator to enable development of an autopilot using PID (proportional-integral-derivative) controllers. I’ve been a fan of flight simulators for…

Verilog Is Weird
Verilog is the most commonly used language for hardware design in America (VHDL is more common in Europe). Too bad it's so baroque. If you ever browse the Verilog questions on Stack Overflow , you'll find a large number of questions, usually downvoted, asking “why doesn't my code work?”, with code that's not just a…

Ode to the AA Battery
Recently this post from @Merocle caught my eye: I'm fixing my iFixit soldering station. I haven't used it for a long time and the battery has gone overdischarge. I hope it will come back to life. Unfortunately, there are no replacements available for sale at the moment. Devices with built-in rechargeable batteries…

A legend reborn: Microsoft brings back the iconic Classic IntelliMouse
Microsoft IntelliMouse. Originally launched in 1996, it became instantly famous with gamers and highly regarded as a great gaming mouse. The IntelliMouse 3.0 had exceptional ergonomics due to its the asymmetric from, and sculpted buttons and finger rests, making it fit perfectly into your hand. It also used long life…

I Tried VR and It Was Just OK
It’s been about a year and a half since I wrote The Road to VR, and a… few… things have happened since then. * Facebook bought Oculus for a skadillion dollars * I have to continually read thinkpieces describing how the mere act of strapping a VR headset on your face

Mute Your Microphone While Typing with Hushboard
Yesterday while surfing the ASCII highways of IRC (yes, IRC) a URL linking to a MacOS application scrolled by my screen. Unclack is a small MacOS utility which silences the microphone of the user when they’re typing. The purpose is to prevent the noise of typing being passed through to other participants when on a…

Tiny, tamper-proof ID tag can authenticate almost anything
A cryptographic tag developed at MIT uses terahertz waves to authenticate items by recognizing the unique pattern of microscopic metal particles that are mixed into the glue that sticks the tag to the item’s surface.

Semiconductors are more than just processors and GPUs
If you ask a software developer the question 'What are some example uses of semiconductors?', they'll probably mention 'silicon chips', like the ones found in processors or graphics cards. Indeed, this is probably the answer that I would have given just a couple years ago, but I have since become enlightened as to the…

Apple's long processor journey
There have been multiple generations of Macs. Apple has not really divided them up. 1. Original 680x0 Macs with 24-bit ROMs (ending with the SE/30, Mac II, IIx IIcx) 2. 32-bit-clean-ROM 680x0 Macs (starting with the Mac IIci) 3. NuBus-based PowerMacs (6100, 7100, 8100) 4. OldWorld-ROM…

How to improve the RISC-V specification
My main project is to create an executable spec of the Intel Architecture but, every now and then, I get to take a broader look at ISA specifications and think about the strengths and weaknesses of other ISA specs: what makes them work well; and what techniques they could borrow from other specifications. Earlier this…

USB-C and Modular Smartphones Are the End-Game for Convergence
Two new technologies – the modular smartphone and USB 3.1 – are set to radically accelerate the convergence of everything to a single, in-pocket device. In fact, they are so revolutionary that they will change the entire way we think about mobile computing as the iPhone did earlier this millennium.

Programming with RISC-V Vector Instructions
Perhaps the most interesting part of the open RISC-V instruction set architecture (ISA) is the vector extension (RISC-V "V"). In contrast to the average single-instruction multipe-data (SIMD) instruction set, RISC-V vector instructions are vector length agnostic (VLA). Thus, a RISC-V "V" CPU is flexible in choosing a…
