I give seven time a years. Do you know why? I might need transfusion

I see nobody has answered, so I'll chime in. Ding!
Thanks!

Did you mean the IRL2703, which is a 30V 60-milliohm (with 4.5V
gate drive) TO-220 part?

Yes.

Your 7555 circuit is OK, I suppose, but I suggest you add
a say 100-ohm gate resistor to slow the FET's rise/fall time a bit.

Is there a reason for wanting to slow the FET's rise/fall time?

Normally we'd ask you to characterize the load,
It's a common Vivitar 2000 Flash. I measured a load of
80 ma after it was charged. I'm guessing 2-3 amps
from a cold start up. The flash uses 4 AA's; we might
use an external pack of 4 D cells instead.

I expect the circuit to reduce power consumption by a
factor of 10.

The IRL2703 was my best guess after learning what I could
about these parts and looking through the Digi-Key catalog.
Mostly I figured something cheap with a very low voltage
loss when the flash recycles.

I'm hoping that some experts will second guess me, in case
it turns out that I really don't understand as much as I think
I do :cool:.
For example, is there any reason to add an external component(s)
to protect the MOSFET, or perhaps there is another part that would
be more tolerant of any transients that might occur.

Hmm, "Trail cameras are cameras placed out in the woods to take
pictures of wild life, tripped with an IR sensor." Tell us more.

My brother wants to build a couple of these things. Apparently there
is a following for these devices. A couple of web sites on these:

Teflon??

Carl Sachs

Thanks Carl, but I thought Teflon was an insulator. Are you referring to
some sort of graphite-impregnated Teflon?

Don, We need to know a little more about what you are trying to do.

Sheet restivity has dimensions of ohms, not ohm-meters. so it is not
clear what conduction path you are thinking of.

Also will you be using DC or could you work at high frequencies? At
high frequencies the thickness of sheet involved in point-to-point
conduction depends on the frequency.
Oops. I didn't convert to meters before I divided. Here are (hopefully)
the correct values.

t = .031 in ---> 387 x 10^3 ohm/square
t = .062 in ---> 96.5 x 10^3
t = .125 in ---> 24.2 x 10^3
t = .188 in ---> 10.8 x 10^3

Sorry about that.

Last check we are up to 350 million dollars pledged.
I have just heard the latest ITV news, the US has now upped its
commitment by an order of magnitude, and has indeed now pledged180 M
UKP. That is in the ball park of the $360 M you mentioned.
That is good news.
I have now no further wish to continue in this thread.

Aside from the immediate needs, there are long term matters. It will

You don't ask stupid questions in a crisis like this. You just
pour in
anything that comes to hand, as quickly as you can. Efficiency is
of
secondary importance. It is NOW that they need help. BEFORE
TONIGHT.

No, this error was learned the hard way in Africa. with stuff being
shipped in that was of absolutely no use to the people.

As long as some needed stuff gets there very, very quickly, it is
irrelevant what else finds its way there.
You mean like the load of powdered milk that was shipped to a lactose
intolerant population some years ago in a frenzy of feel-good "do
something now"?

Given that the transportation and distribution resources are limited
at best, it would seem to me that some thought needs to put into what
real imminet needs exist and address those first.

In this case, what many places need are roads.

And there are many places which *are* accessible and which are in
urgent need of help.
Sure there are.

Now all you need to do is catagorize them as to what is actually urgently
needed.

Is it water, food, diesel fuel, antibiotics, mosquito nets, blankets,
insecticide, shovels, pumps, or what?

Anyone got some
dehydrated roads to ship out?

Funny ha ha.

Thanks, Rich. The War Department happened to look over my shoulder as I read
your post. You were right, she laughed (urban legend or not).

Happy new year (and send wishes for the best to all your alter-egos,
particularly the one with the pig bladder)

I am surprised that 9/11 is still so formost to your mind; I'd have
thought that the hurricane damage done last year would be much more
relief-worthy. Then again, being a natural disaster, it can't serve as
well to polarize opinions, can it?
There is a difference between a natural disaster (aka "act of God") and
an act of War. If a typhoon had sunk the American fleet at Pearl Harbor
in 1941 there would have been sadness, but no anger or alarm. The fleet
was sunk by a Jap attack. Therein lies the difference.

a 7 HP single phase motor will not be quick or easy to source at a
cheap price IME. Even 5Hp is unusual.

In any case, is it possible to change the motors out? None of these
are too big to not be used as single phase motors. The biggest factor
would be the mounting type. If you weren't so far away, I could
probably give you at least one of each size, but shipping from my
location would be cheaper to go buy a new one or close to it.

Urban legend.

Who cares? It's still a good story.
Actually, it wasn't a good story and I suspected it was an urban legend,
but didn't want to bother looking it up on Snopes. Any woman would see
right through it. The likelyhood of a OB/GYN rescheduling for earlier in
the day than the original appointment is mighty slim. Usually they're
calling to tell you the doctor's delivering a baby and you'll need to come
in later/another day or see the nurse practitioner. There are other issues
with it as well that made it stink of urban legend. Overall, the story
made me roll my eyes more than laugh due to its implausibility.

If we're gonna talk good urban legends, at least chose one with a little
plausbility like the rocket car story that got the Darwin Awards early on.
True, the bumper sticker bit should have been a dead giveaway that it was
a story, but compared to some of the other stupid stunts pulled by Darwin
Award nominees, it at least seemed plausible.

And Rich, why are you cross-posting to so many groups? Divergent themed
groups with members that don't all know how to trim posts at that. So not
the Slack way. Been hanging out with rm too much?

Yeah, and the funny thing (if anything about this can be called funny) is

country need 2 years to have its resorts back online.
Yup. Of the countries involved, Thailand is a quite developed country.

What aid did the US expect, and why did they not ask for it? What are the
numbers for the aid to Spain from the US after the Madrid bombing?

To be crude, but honest, 9/11 is nothing compared to this disaster.
