Saw this on Hackaday, a really excellent video and worth watching. Micah is one intelligent woman. I happened to catch at 6:50 in the video something very familiar to me..... a Parallax Prop Plug being used in the efforts to hack the drive!

ps. I absolutely love the visual representation of the coding flow shown at 20:50. Really wish I could visualize my SPIN code the same way.

    Scanline/scanlime. Micha/Micah. Not doing too well today, are we! :lol:

    Anyway, great video. Her puddy-tat doesn't seem too impressed though. Cats are hard to impress, anyway.

    Oh Boy - she makes me feel really STUPID!!!!
    Has she ever had a conversation with Chip???
    If I was to hear above conversation - would I understand a word?

    Amazing stuff - I wish I understood a 1/100th of it.

    Not to take ChipG away from what he's doing, but he's one of the few people I know who might be able to translate that video for us. :)

    What a great story of exploration.

    I like that idea of viewing a binary file as an actual image. Simple but effective. Gives some very striking clues as to what you are dealing with.

    Now, what do binaries from the Spin tool look like? I bet those areas of Spin byte code and PASM stand out.

    Time for a quick experiment....

    Thanks Gordon - I might have figured that out if I had watched on a mountaintop somewhere in Tibet! Unfortunately- I was in my living room on the floor... :-)

    When you need a RS232 to 3v3TTL converter, if you have a PropPlug you are set. I use mine to access my WikiReader's serial back door.

    I don't understand what you mean by the above statement.

    Isn't the PropPlug only useful for converting between USB signals and 3.3V logic?

    I didn't think the PropPlug had anything to do with RS232 signals.

    Quite right Duane D, I meant if your computer expects a RS232 port and you need it to come out as 3v3TTL a PropPlug is a great general purpose tool. You're quite right that it does nothing for you if you already have RS232. It looks like a RS232 adapter (FTDI variety) to your computer but what you get is 3v3TTL instead of RS232.
