oops. quite a lot, really ;) it says here:
- operating voltage 3,6 to 8,4V (I've got 6V)
- No-Load value 2A (I was having NO LOAD ;) )
- well. okay, at max. efficiency it says something about 12A here ;)
- and "stalled" the current is a mere 85A ;)

anyway, under testconditions it should work as the specs for the
L298 talk about a peak current of 2.5A per channel "Non repetitive"
and 2A under DC operation.

Under real operating conditions it does, I agree.
So back to relays, as I said ;). At least, with a little modi-
fication I have got myself a real sophisticated way of driving
the relays using my L298 device ;)

I'm sorry, I posted the wrong URL. I meant:
http://www.dprg.org/l298.html (which does use real L298's but what
You said about the current is still true, of course).

we could have a little campaign like "Save the whales":

"SAVE THE WALTS"

How 'bout that?
