STMicroelectronics STM32F1 Bypass read-out protection (RDP) .
Interesting blogpost for anyone into microcontrollers hacking.

ETH Zurich is developing a new radiation-robust microcontroller that uses the triple lock-step method to validate its own computational results. The basis for this is a RISC-V based design.
Lockstep is nothing completely new in the RISC-V area either, but the focus on energy consumption is interesting. Perfect for satellites!
Andreas Spiess reruns a video from 5 years ago in which he destroys or damages several components in an attempt to build some random project he found on Instructables and then connect it to electronics it was never originally designed to be connected to. It is a favourite video that I refer people to whenever they try using a microcontroller, Raspberry Pi, etc to switch inductive loads https://youtu.be/ReFUr3KuK40
A short history of the over four decades old Intel 8051 microcontroller series and some contemporary developments. Very interesting as it's a world I didn't know much about beyond the 8051 name.
#RetroBSD is a port of 2.11 #BSD#Unix intended for embedded systems with fixed memory mapping. The current target is #Microchip#PIC32#microcontroller with 128 kbytes of RAM and 512 kbytes of Flash. PIC32 processor has #MIPS M4K architecture, executable data memory and flexible RAM partitioning between user and kernel modes.
Remarkably Accurate Quartz Clock update: I last calibrated the clock 34 days ago. Today it was about 0.4 sec late, which would translate into under 5 seconds per year. Battery in this time went from 3.092V to 3.009V.
Remarkably accurate update! Nearly 3 months have passed since the last calibration. Clock drift is still under 1 second, which would translate into a beyond-expectations accuracy of <4 seconds per year. Battery is steady at 3.011V.
