Yes, the unloading is happening over 4.5 volt track so that I can discharge
into a bin below. Also I'm working on making the same section of track act
as a scale by using some springs and a rotation sensor.
As for the how the RCX will interact with the hopper, I'm undecided. I have
though of replacing the levers with gears, but I more I play with the levers
I think I'll leave them on so the cars can still be used manually. So I'll
probally build some kind of clamp that is controled by the RCX and will
squeeze the levers on the Auto Hopper.
Glad you liked it,
