Recently they were redesigned somewhat and labeled on the Parallax site as RoboGames badge of which I bought one. This is the only reference to a badge that I know of. Since their new site went up, the old link to their RoboGames badge no longer works.

I am trying to control 40 LED's (actually motors), so I might try charlieMultiplexing with either the BS2, the SX, few 74HC595 or the MAX7219 for my current project.

However, since I am an SX/B beta tester I have the latest unreleased SX/B which one new feature allows arrays on an SX-28 to be larger than 16. So I utilized this in the design. Check out the link and especially the YouTube video. http://forums.parallax.com/forums/default.aspx?f=7&m=211040&g=211445#m211445 I believe an SX-28 has larger arrays (more than 16) so it should be possible to do this on an SX-48 protoboard too - until SX/B v2.0 is released in the future (I don't know when).

I posted a picture above to see if anyone can help. The arm has 40 actuators, and I need to control each one separate. my idea was to take each LED signal; amplifying it, so each signal controlled one actuator. any ideas?
