I won’t bother to link pics here ‘cause it always takes me at least 3 tries to
embedden ‘em...
Anyway, with much further ado, here’s my latest POC--
Externally powered monorail!!

So a few things--the copepr tape is a little stretchable, so after the first
disaster of laying down the tape on the curves (soooo amny bumps and folds!!), I
got the hang (mostly) of it and the copper tape on the subsequent curves are
pretty smooth. Janey gave me good ideas with the cutting and overlapping from
stain glass working, but the tape can strrrrretch a wee bit to accomodate the
curves without issue.
I haven’t taped up a ramp part (should be no issue) and will try to some evening
this week.
I also havent’ tried a switch track. First, because I’m loathe to use switches
in a display layout now--they just get worn way too fast at a show, and I
haven’t quite figured out how to cross the copper at the juncture. I have some
ideas and maybe I’ll experiment, but since I don’t use switches in display
layouts too much, it’s low on the priorities.
I tried to get some good LEGO geometry going to connect the 9v train power
connectors to the monorail track. No go--the power connectors don’t conform to
a good LEGG geometry :( For now, I’ll just solder the power connector wires to
the copper tape and go with that.
But the big news is that since the monorail can run off a LEGO train controller,
it can (wait for it)... be RCX’ed...
OMG! stops without using monorail stop switches. Variable speeds!!!
Yeah, I’m pretty excited.
I’ll try to have at least 1 full loop up at our next show in two weeks.
I’ll keep ya all informed as I go.

| (...) Woah, that's pretty cool! How does it handle any start/stops that it encounters? I assume that the switch on the motor wasn't actually disengaged, so it it needs to be out to the left or right in order to work? DaveE (14 years ago, 8-Nov-10, to lugnet.org.ca.obb, lugnet.space, FTX)

| Dave, I am so proud to say I know you. You sir are amazing. I would also like to anounce to the comunity that I got to see Dave build his first working prototype at the hobby show. I should also point out that at 6pm, I told him he had to stop (...) (14 years ago, 9-Nov-10, to lugnet.org.ca.obb, lugnet.space, FTX)

| (...) WOW! That is awesome. I am going to have to try this sometime in the future. I will suggest some <https://plus43.safe.../p358.html HO pick-up shoes> for the power though. Not sure if those would work without some more invasive modding though. (...) (14 years ago, 10-Nov-10, to lugnet.org.ca.obb, lugnet.space, FTX)
