I don't want to start a my mod is better war, and I'm only replying to
the above to clear some misconceptions that the above article might
create.  I don't care whose mod is used, and if I had known that someone
was going to post a mod, I would probably not have posted mine.
To reply to some specific points raise above:

	Yes the *RESET line should be kept high, and if you look at the
	circuit I posted, you will find that it *is* kept high. Conversely,
	when you press the reset button the line will go low. Please do
	not post erroneous information.


	The second reset button is the only one you need to use to reset
	the whole system. Yes, it is a bit of a hack, but personally I
	thought it was a reasonable solution given the constraints.


	BTW, the mod I posted is quite sufficient if you are going to be
	using the ST for most of the day, and will leave if off at night.
	If, on the other hand, you want to just use it for a few hours
	a day, you should think of getting larger capacity Ni-Cad cells,
	and making a real charging circuit for higher charging rates.

	Finally, the mod given above works. I have been using it
	for about a week now.
