After reading Dave Koudys’ conversation with fellow RTL’ers about installing a DCC decoder directly
into a Technic motor, I became inspired to actually build such a beast:

So, why is it a smart motor? Well, the idea is that you can wire many of
these motors in parallel to a single RCX output and still individually
control each of the motors

Well, you rock! That’s exceedingly cool. Please build more! Indeed, you might
consider building a largish batch of them -- if you set yourself up
assembly-line style, you could probably knock off a couple dozen of them in a
few evenings and sell them for $40 apiece (or more).
It’s a very exciting development, since as you say, it’s very lego-like. One
RCX brick controlling any number of motors -- how cool is that?
Of course I suppose that power would become a problem if you hung more than a
few motors off one RCX output. Any thoughts on what to do about that? E.g.,
would it be possible to rig it so that the motors draw their power from another
source (an RC car battery for example), and just get the command signals from
the RCX? Or is this not an important issue?
Best,

| (...) I imagine you could bang them out fairly quickly once you've done a few. But, when I mentioned the US$35 figure, that was $16 for the decoder and ~$17 for the motor (via BrickLink). That still doesn't include any taxes and shipping. So, as a (...) (20 years ago, 9-Sep-04, to lugnet.robotics, FTX)
