Microcontroller-less i2c adapter

This is so cool…Phillip cut a video cable and brought out the i2c lines that are used to transmit/receive data from the monitor/display. (I guess that’s how well designed drivers know the resolutions available)

Some drivers let you poke data onto this bus, so you now have a way to communicate with i2c devices (like, say…a wii nunchuk). PC’s also have an onboard i2c bus for sensors, which I mentioned in my blinkM post.

  1. Hey keen! Thanks for noticing. There’s a slightly more descriptive version (with additional pictures) here at Instructables:

    (And on a tangent, wow, the Wave Shield is exactly, Exactly, EXACTLY what I’d been seeking for another project! Just ordered one to mess around with.)
