Oh yeah, one other thing. I’m not sure how much voltage or current the inputs
can handle. There might have to be some kind of load in between the two RCXs.
I was thinking of using a bunch of 9V lights connected in series (that’s
actually hard to do -- try it sometime.)

Voltage shouldn’t be much of a concern, unless the RCX has a transformer to
allow it to output higher voltage than the internal batteries can provide.
Besides, wiring up a bunch of 9v lights will increase the total voltage needed
to make them glow...but it won’t affect the voltage supplied through them (I
once had to wire ten 12v mini-PARs in series so we could safely run 120v current
through them as practicals in a play). If you want to decrease the total power
supplied to the RCX, I believe you’d be better off wiring them in parallel, as
that won’t do screwy things to the voltage.

It’s been a long while since I took physics, so I think I need a coil of
wire, not just a wire/electric plate. And a much bigger magnet.
|
I don’t recall for sure, but I think you’d need to have the magnet inside a coil
of wire, either moving through it, or rotating inside of it. You might consider
trying a magnetic lever that would lift as each magnetic coupling passed over
it, tripping some sort of physical switch.

| I'd like to share two thoughts with you all. They involve the RCX and doing things with it that I'm sure the designers never intended (or thought possible). Oh, if you're reading this in the .trains newsgroup, you can skip over the first thought (...) (21 years ago, 1-Sep-03, to lugnet.robotics, lugnet.trains, FTX)
