  • The Actobotics hub mounts attach reasonably easily to these wheels. You’ll want to get 1 inch actobotics standoffs to replace the existing standoffs with and some bolts to put it all together with. The upside is no need to drill out (and fix your size) for the original grub mount, the downside is probably around $7-12 per wheel depending on hub mount.

  • Using this breakout board from the BeagleBone Black: http://www.linux.com/learn/tutorials/765810-beaglebone-black-how-to-get-interrupts-through-linux-gpio

    Using two ripple counters and a pin mux chip to give the trackball an I2C interface (handy for arduino) http://monkeyiq.blogspot.com.au/2014/01/ripple-counting-trackballer-hall-effects.html

    Probably a batter IC combo to do the later. Hints welcome ;)

  • Anyone had luck running these at 3.3V?

  • Thanks for this! I was getting the “ax ax” and then random junk, the extra init line from the PR fixed things.

No public wish lists :(
