Howdy y'all! In this friendly little tweety-box thread, I'd like to share my new project with you. It's called the GoodWatch, and it will be next month at Shmoocon. 1/n

Here's the pinout for the flash programming port. It's in a different order compared to the one on the SCSA D-Ark.

Apart from the content quality, the paper and print is also high quality. Something you don't see everyday with technical books. It covers real world attacks on MCUs like STM32 series, nRF52, etc. Also techniques like glitching and chip decapping. Here's table of contents:

Another Heat cost Allocator looked into. This time an Ista non RF Variant. Decapped Blob turns out to be an MSP430C413 8KB ROM 256 Byte RAM Other than that its just: - Custom LCD - 2 Temp Sensor - CR2477 Battery - IRDA Interface Not much to "hack" on without RF and ROM based SoC

Modern Binary Exploitation by @RPISEC. This was a university course developed and run solely by students to teach skills in vulnerability research, reverse engineering, and binary exploitation. github.com/RPISEC/MBE

IBM 360 panel from the old Living Computer Museum in Seattle. Wonder where it went?

Turns out this was easy to repair, certainly the classiest of my EPROM eraser collection.

This was 1993. Despite all of the problems with VB ("not a real language", the runtime DLLs, etc.), it was So Much Fun™️ to create apps this way.

Taking apart my FT-891 for this mod was SO worth it. When will all radios come standard with Anderson Connectors? I mean Xiagu saw the trend and already does. #AndersonPowerPole #Hamradio

This is a friendly reminder to order replacement capacitors for your HVAC system today, so that you aren't miserable when they eventually fail. It'll also save you hundreds of bucks on a service call.

Just dropped a blog post on reproducing a known voltage glitching attack to bypass APPROTECT on the nRF52840! 😎 Spent hours soldering & debugging to get it right. Not novel, but a messy journey—check it out: matiassoler.com/posts/approtec…

I just have released the schematics and PCB of my transputer board, along an article describing the process. Enjoy it! #retro #transputer #ibmpc #dos nanochess.org/transputer_boa…

Hahaha this epoxy is super heat sensitive! It flakes right off. We accidentally pulled the stm32 off on this one! Yanked several pads. Whoops :) @watermelongames #paprium black epoxy is compromised severely by heat. It literally bubbles up and flakes off.

OK I've uploaded my from-scratch 80286-like softcore CPU to github: github.com/nand2mario/z86 🚀 It is still a WIP. But it should be fairly complete, at least in simulation. 5-stage pipeline design like the 80486: Fetch, Decode1, Decode2, Execute, Write-Back.
