  1. 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.

  2. 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.

  3. I feel horrible even attempting to pull every string I may or may not have, but...

    I have a #GRiDCASE 1537 that was govt surplus. It malfunctioned, and Curt Vendel offered to fix it. After almost 5 years, I got it back, but it's in pieces, and am looking for some1 to fix it.

    This is a tall order, because the schematics for this thing are classified, and will require someone versed in hardware #reveng to do it.

  4. Live at twitch.tv/cyberkaida ! Today we're looking at datatypes in Ghidra and how to extract them from one binary and apply to another! 👩‍💻🐉

    This is really useful when working with common libraries and makes RE much easier! ✨

    Come hang out!

  5. Yesterday I've learned what USB filter drivers are on Windows and that it's apparently pretty easy to install libusb0 as one. (Thanks @patagona)

    Having done that, my initial plan worked on the second try. I can now send the command for switching the color palette, wohoo \o/

    I only needed to make sure that I send the USB control transfers after the video capture has already been started, otherwise the call to #libusb will just hang indefinitely for whatever reason.
