Hi Trevyn, From the photo you posted, it appears that you have the input and output pins of the 7805 reversed. According to the datasheet, this will probably fry the regulator. I'd recommend getting a new part before continuing, so as not to risk (...) (24 years ago, 2-Feb-02, to lugnet.robotics.rcx)

I just saw Styx-in-a-brick at Linuxworld. (Styx is the distributed file system component of Inferno and fits into 17k.) The RCX was built into a clock (time display device) and was keeping in sync with the host machine via infrared. On the host (...) (24 years ago, 1-Feb-02, to lugnet.robotics)

Cool stuff, congrats on the Slashdot recognition. Hope the "Slashdot Effect" didn't totally cripple your server.

(...) Taking a look at the rules, there doesn't seem to be any penalty for touching the walls, so I dont see why you couldn't use a single RXC with 2 motors and 3 (or 4) touch sensors: left, front, right (back). These can be multiplexed onto a (...) (24 years ago, 1-Feb-02, to lugnet.robotics)

I was looking for the data sheet for the Melexis 10402 motor driver IC, the one in the RCX. It is no longer on their website. I eventually found it, and have posted it here: (URL) want to drive 24V motors and use the RCX to control them. Ideally I (...) (24 years ago, 1-Feb-02, to lugnet.robotics)
