Subject: [alt-beam] Ripple current and Goop problem


With a title like that I am sure the curious would read this :)

I have 2 questions; any help would be appreciated.

1. what is the term 'ripple current' meaning in relation to capacitors? I
have a catalog here and one of the specs for these caps is there 'ripple
current'. Any ideas?

2. I recently bought from a pawn shop a little LCD casio 'Marine Hunter'
game for AUS$3, for the reason that it had a reallly nice solar 'battery'
(more than one cell!) - it looks like the suncerams that I have never been
able to find locally. Anyway, the LCD game is pretty bad, so I have no
qualms about stealing it's power source. The problem is, it has been fixed
inside with some kind of herculean double sided tape. What should I do to
get it off? I don't want to pull off any coatings/layers (the tape is on the
back of the panel) nor do I want to kill it with the wrong kind of solvent.
Any suggestions on a solvent that is 'cell friendly?' - I really like this
solar panel as it works brilliantly under even dodgy flouro lighting!

PS: The game was made in 1983, and still going. Hmm... 16 years and still
needs no battery :)... Maybe my next bot can be that good :)

Thanks for the effort of reading this!

Jacob
