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

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.
A comparison 21 different microcontrollers — all less than $1.

I'm not sure where this came from (some class handout?) but it is a very nice guide to hand-drawing Bode plots.
Educational electronics weblog with a good name I came across today.

Robert Baruch is getting custom LCDs manufactured in China at surprisingly low quantities and total cost.

These low-cost 8051 microcontrollers with USB look interesting.
