I received my free (+$3.95 P&H) upgrade kit today and was pleasantly surprised ( or should that be AMAZED, Y-A-H-O-O-O-O!!!! and THANK YOU LEGO) to see that was NOT just a software upgrade, as I had thought, but the full #3803 "RIS 1.5 UPGRADE KIT" (...)

Wes, I'm sorry; I missed the Rcx Motor info... If the Rcx Motors start/run with 6V but don't work with the Rcx Outputs, something is 'Funny'. The Rcx, with decent batteries, puts out about 7 volts to a running Rcx motor (full power setting). I'm not (...) (26 years ago, 10-Nov-99, to lugnet.robotics.rcx)

Hi all, If you still want to get a (second) RCX with a power connector, order online from www.legoworldshop.com. Make sure you order the RIS 1.0. Lego will throw in the upgrade to 1.5 in for free, so you still get the same set. I just got mine. I (...) (26 years ago, 9-Nov-99, to lugnet.robotics.rcx)

The simple thing would be to do the short delay in the software. Identical relays usually 'make' faster than they 'break' due to energy stored in the magnetic circuit. It's hard to do this without active components. If you use a typical small (...) (26 years ago, 9-Nov-99, to lugnet.robotics.rcx)

Wes, relays would work pretty well. (Still, how much current do your motors draw???) The LEGO motors draw about .35 Amps (350 Milliamperes) You could connect two 5V coil relays , each with a diode in series with the coil, connected oppositely to (...)
