The first two weeks of hackerschool was way better than I expected.
Some of the highlights include learning how to use the BeagleBoneBlack PRU with Dana, building a wifi probe request sniffer using libtins, and finishing the first week of stanford networking course CS144.
Inspired by Ambers post on trying things you are scared of, I'm going to retackle this NES sniffing project. The goal is to identify and display what cartridge is in a running NES. My plan is as follows:
- Get the beaglebone PRU to trigger interrupts on the phase2 pin of the nes
- Read the LSB of the data line in that interrupt
- Write 512 bits to shared memory
- Do this a few times
- Find longest common substring and try to guess a 'header' to know when we should actually read
Small things that happened in the last week
- d3.js graph to add nodes and links to visualize a mesh network
- getting cjdns up and running on OSX & a beaglebone with the help of PSST!, GRRR!, and nyc meshnet
