For experienced hardware hackers: an advanced guide to fun with microcontrollers. Learn to pull firmware from single-chip computers, even when they're configured against extraction.
This book details a wide variety of techniques, so you can reproduce real-world chip exploits in your own lab. Plus, find encyclopedic coverage of vulnerabilities for your hardware security work.
Our second episode of #DayGlowShow streams live July 10 at noon Pacific (tomorrow / 7pm UTC)!
@ishotjr and I are digging into the #PicoCalc – a #microcontroller development platform based on the #RaspberryPi Pico. Plus, reflections from #Teardown2025

Letzte Woche habe ich renoviert, denn mein Sohn sollte in das Zimmer seiner Schwester umziehen die nun bei ihrem Freund wohnt. Und ein Wunsch des Sohnes war ein LED-Streifen, im alten Zimmer hatten wir einen billigen Streifen aus dem Baumarkt direkt an sein Hochbett geklebt, für das neue Zimmer hatte ich aber besseres im Sinn.
Proof of Concept
If you've ever played around with TI microcontrollers, you've probably had to use the Code Composer Studio, which is fine and all, but I found out recently they made their own open source C compiler.
It's nice to know that they not only have a compiler I can use (meaning I'm not locked into using an IDE), but that it's also on the AUR!
(`yay -S msp430-elf-binutils msp430-elf-gcc msp430-elf-gdb` :-) )
“Raspberry Pi RP2350 #microcontroller now available to mere mortals: ‘There are also #RP2350-based devices out there, such as the Thumby Color, a wearable keychain controller with a 128x128 16-bit color screen.

TI's tiny #microcontroller is the world's smallest and costs less than 20 cents - https://www.zdnet.com/article/tis-tiny-microcontroller-is-the-worlds-smallest-and-costs-less-than-20-cents/ " This remarkable device is only a little larger than a pepper flake." insane
Does anyone know QEMU well? I'm trying to figure out how to control the virtual TMP105 built into the #ESP32 fork of QEMU. If I build/run with "idf.py qemu" it magically works (reads from the virtual I2C TMP105 at addr 0x48). How do I change the temp in qemu? #iot #microcontroller
Right, some initial notes on these #RP2350 Melopero Perpetuo #LoRa boards: https://yvan.seth.id.au/melopero-perpetuo-first-notes.html
Long story short: they work... I can make LEDs flash, that's the key thing... right? 
Can also read the internal temperature sensor and check battery status.
A few "bugs" in the examples and a slightly faulty board.
So far, so good... Next job is to get one of them transmitting the temp and battery status to the other. Will need to think about how to "package" that data for reliable tx/rx, probably need some redundancy, etc, maybe a buffer window of data. Then I need to dig out some of my various sensors and decide what to hook up to the "remote" to send to the local. The local will probably then relay data to a connected computer via the serial console I guess.
Project #Polytunnel Telemetry is GO! Well, if I can get a signal that far, otherwise this becomes project #Greenhouse Telemetry... the greenhouse is about 30 metres away, the polytunnel is a kilometre.

I need your help, dear electronic nerds. Does anyone know the exact name of this white connector at the left? I want to buy one (or maybe more), but I do not know how to search it without a proper name. Pleas help. #microController #diy #arduino #connector
Hat jemand Tipps zum Einstieg in #DIY #HomeAutomation devices für eine #Zigbee2MQTT #HomeAssistant Landschaft?
Ich hab ein bisschen Erfahrung mit #Arduino und #ESP32 Letztere gibt's zwar auch mit #Zigbee, sind aber eher nicht für den Einsatz mit Knopfzelle oder einer AA(A)-Batterie geeignet und lassen sich wohl auch nicht per Funk aus dem Schlaf wecken.
Mein Ziel wäre, eine #Microcontroller-Plattform zu haben, auf deren Basis ich batteriebetriebene, wartungsarme einfache Sensoren (Tür, …

Currently covering STMicroelectronics' STM32N6 launch, an 800MHz(!) Arm Cortex-M55 microcontroller with 1GHz(!!) Neural-ART in-house machine learning coprocessor.
Seems like a heck of a bit of kit, but STMicro's claim that it's the first microcontroller to include AI acceleration is... err... not even close to being true?

I wonder how hard it would be to implement a Bluetooth #VT100 emulator using a modern microcontroller, maybe an Arduino with a little display and keyboard. It's what RFCOMM was actually meant for.
It seems like the original VT100 is extremely well documented with beautiful pictures and everything.
The modern computing stack has grown way too complicated...
So! Does anyone have any tips for creating an RP2350-based computer with a custom operating system?
Hoping for something between a fantasy console and TempleOS, but with the ability to do actual work (word processing, emails, etc)
...this is too much of a niche, complicated, and/or cursed topic for me to ask about so casually, isn't it?
RE: https://infosec.exchange/@joshbressers/113205747745148013
Something that would be really nice is a way to bring all the GPIOs from a #microcontroller dev board down to a mini breadboard without having to use jumper wires. I wonder if there's a way to drill out the back of a breadboard and shove 0.1" headers into it to connect to the internal bus bars.
