In the latest SAH catalog (Fall 2001, rec'd today in Massachusetts), in the
Mindstorms section, there are two "new" parts. One is a solar panel, and
the other is a capacitor.
I know these are former/current Dacta items. The page also says to go to
www.lego.com/dacta for "more information on how to use energy in your
creations" (or something like that, I am paraphrasing).
But I can't find anything there on this subject, especially about these
parts.
So, can these really be used in any way? Can the RCX be powered by either
for even a brief or partial time? For example, could I use them for running
the RCX and sensors, but not motors? I can't believe there is even enough
current from either to do much with motors.
And the worst thing: how are you supposed to use these things? It seems
like a terribly uncoordinated thing for LEGO to do to sell these. Both
units appear to have the standard 2x2 connector plate area, but I am not
aware of a way to get that into an RCX. Or am I missing something?

| There is hardly enough current to move a motor. You would need about 9-11 Solar Panels and a bright sunny day to power the RCX. My only attempt at working with this solar panel can be seen here: (...) (23 years ago, 13-Sep-01, to lugnet.robotics)

| I have performed some experiments using the Lego Solar panels and capacitors to operate the RCX. I used the 5 volt configuration on my site at (URL) two AA batteries in series with the output of the solar capacitors. This resulted in a 7.5 volt (...) (23 years ago, 18-Sep-01, to lugnet.robotics)
