|
| I investigated this issue a while back an have taken apart all four of my RCX's (1.0 w. adapter, 1.0 w/o adapter, and 2 2.0's from an RIS1.5 and and RIS2.0). They all have internal voltage regulators. I've written the number down somewhere on this (...) (23 years ago, 2-Feb-02, to lugnet.robotics.rcx)

| Hello, one of my beautiful new rotation sensors was jammed right out of the box. I built a robot to try out dynamic equilibrum, i.e., balancing a weighted stick, only to notice that my construction didn't turn at all because of sensor friction. (...)

That isn't the real reason though (I could always handle that in software). The real reason is that ever since I (...) (23 years ago, 6-Sep-01, to lugnet.robotics.rcx)

| Hi, all - I was reading through the sources, and I noticed that starting with 0.2.3, there was no dsound_play. Does anybody know why the 8 kHz sound playing subsystem was taken out? That was, IMHO, a way cool feature. Was it just too buggy? Also, I (...) (23 years ago, 10-Jun-01, to lugnet.robotics.rcx.legos)

To get a reading of 0 (RAW)it seems as though you would (...) (22 years ago, 8-May-02, to lugnet.robotics.rcx.legos)
