         | Also buspirate was registered in 2009, last updated 2023. Same
         | for dangerousprototypes. Seems legit to me.

       | I grabbed a bus pirate about a year ago thinking "oh, of course

       | This involved flashing a third party firmware. From a project
       | which refuses to release binaries. I had to install something
       | like 5GB of toolchains to build it, and then THEN! I had to
       | _manually edit_ the resulting .hex file. At some point the binary
       | is converted to an ASCII representation of the hex pairs, but all
       | letters converted to uppercase. Then it 's parsed back into
       | binary with the wrong values. I had to manually search and
       | replace uppercase letters with lowercase.
       | 
       | I've seen a lot of dumb software nonsense in my time, but this
       | one really takes the cake.
       | 
       | It also never actually worked. Hopefully the firmware on this
       | revision is less terrible
