Why do what you're good at when you could be doing what you like?
My favorite tournament report so far.
Wesley So on emigrating to the US and how Chess960 is his favorite variant.
Writeup on an effort to design and produce 200 little flyback converters (meant for powering Nixie tubes).
Successfully executing a replay attack against a wireless key fob using inexpensive hardware and GNU Radio (based on Samy Kamkar's original hack).
This is an entire PC-compatible single-board computer implemented with an 8051 microcontroller (!) running an x86 emulator.
I've been able to find very little about the Appotech AX-2005 System-on-chip, just the first page of its datasheet (it runs at 125Mhz):
Seems like good advice.
This TTL computer looks like an interesting design:
-
It implements an 8-bit RISC CPU with an 8-instruction CPU using a surprisingly small number of chips: just 36 standard TTL chips, a ROM, and an SRAM chip.
-
The VGA output is generated entirely in software with no additional graphics hardware (other than a resistor DAC). User code runs only during the hsync and vsync periods.
-
The ROM kernel takes care of all the VGA timing and runs a virtual machine which presents itself as a 16-bit CPU and includes an interpreter so programs can be written in a high level language.
Wow, I didn't know until today that anyone had ever written an OS for the TI-89/TI-92 calculators.

And someone else has made one too! Called Punix: http://punix-os.blogspot.com/
The author of Punix has also published a skeleton OS for anyone else who wants to play with it: https://www.cemetech.net/forum/viewtopic.php?t=7345&start=0
How to write tiny ELF executables by hand.
Pamphlet providing some context and summary of the Book of Amos.
He's no John Bartholomew, but Carlsen is surprisingly good at explaining his moves as he plays.
Good description of a simple preemptive, single-stack task scheduler for an embedded RTOS.
A very nice project report on the design and build of a simple Nixie tube clock including an unexpectedly in-depth section on the design of the custom flyback boost converter. The tubes are driven by individual transistors, controlled by an stm32 uC, powered and programmed over USB-C, and housed in a custom machined stainless steel case.
So far seems like a nice introduction to DSP, and free online from the author!
This review makes me want to play with these microcontrollers.
Arduino started as a fork of a microcontroller library/IDE/dev board called Wiring. Here the creator of Wiring weighs in a bit on the origins of and some of the drama surrounding Arduino.
