Hello, (...) The only problem with that is that you will have to guarantee a max. voltage of 9 or 10 V at the RCX. I don't think usual charging circuits have a voltage limit that makes sense ... Greetings Horst (22 years ago, 23-Sep-02, to lugnet.robotics.rcx)

hi all, i have made some measurements with lnp in legOS 0.2.4 under ideal conditions (dark room with minimal load on PC and RCX) and found that sending a 10 byte message with lnp_addressing_write averages on about 0.06136 seconds (+/- 10 ms for time (...)

In order to protect the RCX from any type of power problems, would it make sense to disconect the RCX from the batteries first and have it run from an alternate power supply? or would this make it too complicated? I know little about electronics, is (...) (22 years ago, 24-Sep-02, to lugnet.robotics.rcx)
