Hackaday YT - Ossmann/Temkin - Accelerometer as a Guitar Pickup w/ Software Defined Amp Reverb & Distortion in GNU Radio w/GreatFET

From ~5 years ago, but popped up in unrelated search results and is mildly amusing. I never have gotten GNU radio working with a cheap SDR TV dongle when I last tried around 6 years ago. It is a curiosity I've been meaning to explore.

Goodasm - 6502 Z80 8051 ++ Assembler/Disassembler - Travis Goodspeed

This is going to be big. It might reshape vintage gaming. From the guy with a repo on reverse engineering a gameboy ROM from a photo of the die.

Howdy y'all,

These days, the world has many excellent disassemblers, but when writing assembly in a weird languages, many of us just fall back to handwriting bytes in Nasm or painfully adjusting to yet another macro assembler. GoodASM is my attempt to fix that.

This assembler is very easy to retarget by extending C++ class and calling a few functions. You pretty much just define the endianness and byte size, then copy the instruction definitions almost verbatim from the programmer's guide.

Defining a new target is completely symmetric. While assembly is the primary purpose of this tool, a disassembler is also produced. An example for each instruction automatically becomes a unit test, insuring that you don't accidentally fat-finger a bitfield or two.

When writing assembly, particularly shellcode, you often have questions that a calculator should answer. What are all the instruction that begin with ro in this language? What are all of the potential forms of the jmp instruction? Does ror a assemble to ASCII? An interactive REPL mode answers these in a jiffy, with tab completion.

If you like this program, please buy my book on Microcontroller Exploits for yourself or for a clever student.

Voice Intercom on Ethernet

cross-posted from: https://lemmy.ml/post/26838835

Hi,

I'm looking a way to make or buy an intercom system between room in the same house. That works more or less like a Walkie-talkie but wired on the local LAN .

With the following "requirements"

  • only voice
  • push to talk ( do not need to dial )
  • broadcast the voice too all receiver
  • AC-powered
  • work on the local Lan (Ethernet)

If you know any device that does that or a clever way to DIY or even an android app (LAN only)
I'm all ears.

Thanks

My apartment complex used to be a hotel and still has the doors. Can I hack the key cards unlock?

Basically the title. I confirmed with management that the system for these hotel style door locks are no longer in use and they likely even moved doors from their original location in the process of remodeling the building into apartments. I'm just trying to prevent myself from getting locked out and avoid using my regular key if I can. I've tried reading it with an NFC reader and it didn't work so I imagine it was to be RFID?

Any tips on where to start? I am an experienced software engineer, but I haven't done any hacking before. I can buy tools to do the job if necessary

Edit: Added pictures for the cynics. It is my apartment
