Subject: [alt-beam] Strange Caps??


I had breadborded solarengine and some strange things happened. I just
ordered some .022F and .047F caps rated at 5.5V from The Electronics
Goldmine. http://www.goldmine-elec.com. The 0.022's are made by NEC and
are labeled FYD and have 264 and F8 running along the side (this probably
isn't useful but....) and the 0.047's are made by Tokin, and have FYL and
118 and I0 or J0 (its hard to read). Anyways, when I charged up the cap,
it would get about to the 1381 trigger voltage, and then the motor would
make a soft humming sound. Depending on how close I put my 100W light, the
humming would get higher pitched, or lower. About twice, I could get the
.047F cap to work, but none of the others did. I am sure it is not the
motor, and I tried replacing the cap with one that I knew worked, and the
SE ran fine. So are these Cap's as bad as the Shack's or what??



PS: I got some junked solar powered yard light that have photoresistor,
NiCad's, and solar cells (duh!). However, the cells are covered in a thin
epoxy or some clear rubbery stuff (like my technical descriptions?). It
doesn't peel off very easily. Any ideas on how to get it off? or is it not
worth the trouble?

Thanks for the help in advance,
Ian Bushong
