Oh yes, this is up my alley!

I went back to playing with angr recently, and learned about the CompleteCallingConvention function today. It analyses a binary and for each function found, it prints the calling convention, parameter and return type. Pretty funny!

Picture shows the angr script on the top, analysis of some random CTF binary's function and related ghidra output on the lower half.

Not only has the Frob #Atari2600 #Gamedev System for #Apple2 been #reveng, Golden Child from #MAMEDEV has emulated it in MAME!

#Apple2 #Atari2600 Frob #RevEng status: mostly done. a few nets not 100% certain, so i'm pinging them out on my actual board using a multimeter in continuity mode. Thanks to Bradley Bell and Curt Sampson.
Reverse engineering designs from crappy pictures and experience... I was curious as to how this PWM fan for Pi worked and whether it would use a similar approach that I would have done. The answer: yep, pretty much. I might make it a bit more energy efficient by using a tiny mosfet instead, though. Maybe.

Sooo … I ditched the logic analyzer and pulled out my scope and … I'm afraid I have to peel off that label again.

Because I don't know if that looks like #WS2812 to you, but it sure doesn't to me. Apparently there's a short pulse, followed by a another pulse that's either short or long. I guess that's the binary encoding.

I'm open to suggestions which #LED protocol that is.

Alt text has some more details and timings.

Strange electronic devices that you have partially reverse engineered should have a label explaining why they are strange electronic devices and what you have reverse engineered.

One idea to explore further from today's Sustain Together meeting:

A legal defense fund and team to fight against take-downs of legal reverse engineering discoveries.

It is *always* worth searching around to see if someone, somewhere has already done just what you describe - especially after a device goes EOL.

I think we're going to see a lot more citizen-level reverse engineering projects bare fruit, as the #enshittification epidemic spreads like #covid.

We're fed up, and those of us who have the skills and time to do these kinds of projects, *are*.

I know I am.

I just saw a guy #reveng his Phillips electric toothbrush. Another replaced the controller board of an otherwise unusable video router with his own microcontroller and code. Tip of the iceberg.
