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 (...) (25 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.

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 (...) (25 years ago, 9-Nov-99, to lugnet.robotics.rcx)
