(...) I just hacked together a quick-n-dirty C++ program to talk to Spirit.ocx. It unlocks the brick and downloads new firmware into the RCX, all using the public methods exposed by Spirit.ocx. I sink events from the .ocx, and I don't get any COM (...) (25 years ago, 27-Apr-01, to lugnet.robotics.rcx)

(...) I mean the active-X events, like "ondownloaddone". I've never seen an active-X component for which you should enable the events. So I presume spirit.ocx will fire an "ondownloaddone" event, when it's ready with the download. But spirit (...) (25 years ago, 25-Apr-01, to lugnet.robotics.rcx)

(...) OK, I'll chime in..... First, this should go to lugnet.robotics.rcx, so I'll post it there and leave the reply in build, but follow up to robotics, please. Without sample code, we can't help, but that's a bit much to ask anyways. Start small, (...) (25 years ago, 25-Apr-01, to lugnet.build, lugnet.robotics.rcx)

(...) Have you enabled the events? You need to both define an event and enable it before it will work. --Ian (25 years ago, 25-Apr-01, to lugnet.robotics.rcx)

hi Ralph, I think I'm lucky. I just did some experiments with a modified IR-tower. The modifications were: the "keep alive trick" from John Barnes and my own trick to add a few more diodes to get rid of the 9V battery. Without a batttery in the (...)

As expected Jeff Hazen and John Barnes sent along a few itmes of interest. (...) Jeff asked if the diffuse cover of the tower had any effect at all. From my experiments, Jeff - the answer is no. John Barnes suggested that the bit-balancing act that (...) (25 years ago, 24-Apr-01, to lugnet.robotics.rcx)

As other people have noted before, the diodes are not located behind the smooth molded "windows" in the tower, but lower, (...) (25 years ago, 24-Apr-01, to lugnet.robotics.rcx)

Hi All, A while back, Ben Erwin asked about other user's experiences with the IR tower and range. I'm trying to characterize a persistent problem with the pbForth serial library, with respect to message reliability. It seems that even in high range (...)

hi John, Some time ago there was a discussion about keeping the IR-tower alive. I want to keep the IR-tower alive, for fast data transport from RCX to PC. You mentioned that you had drawn the circuit diagram, but you never published it. Do you have (...) (25 years ago, 22-Apr-01, to lugnet.robotics.rcx)
