Based upon my sad experience, make sure that the phosphenes are benign

I had a MRI to see what caused the Bells Palsy last year. Loud
buzzing at different frequencies, followed by a migraine that lasted for
the better part of a week. No images or light, though.

and with 39 feet of wire in it, since #10 has a resistance of about 1

Now, let's say that this thing can dissipate 100 watts, continuously.

Since:

P = I˛R

then:
P 100W
I = sqrt --- = sqrt --------- = 50.64 ~ 50 amperes,
R 3.9e-2R

the voltage across the coil would be,

E = IR ~ 50A * 3.9e-2R ~ 2 volts

and its IT would be 50 amperes * 100 turns = 5000 ampere - turns.


Never believe in John Fools Bogus computation. There is no way you can
get 5000 amp on your little 500W power supply wires. No wonder why you
guys are in deep shit. Talking about my exaggeration? Look at yours!,
so fuckingly out of wax formula.

Sad, really...

I apologize for any unkindness I may have thrown your way earlier, since
I didn't realize I was fighting a battle of wits with an unarmed man.

Here, let's try it again but, just for you, a little closer to the
street:

For a solenoid with a 39/1000 ohm coil resistance dissipating 100 watts,
the current through it would be about 50 amperes, while the voltage
across it would be about 2 volts.

Now, (and this is critical, so try to pay attention) the strength of the
magnetic field will be proportional to the product of the current in the
solenoid and the number of turns wound around the core, and in the
example given earlier for a 5000 ampere-turn coil, the number of turns
was clearly declared to be 100 (10 turns per layer by ten layers).

So, if the product of x amperes and 100 turns is 5000 ampere-turns,
what's x?

A. 50

B. 50

C. 50

D. None of the above

Eagerly awaiting your answer...

You need to know more about the encoder's outputs, and the bit pattern.
Does it say if the encoder outputs are TTL compatible or anything? If it

know what bit pattern corresponds to what output/input you need.

Thanks Rich. I have the bit pattern, I just want to toggle individual
bits. I don't know whether the outputs are CMOS or TTL, but encoder's
output sink current is listed as "25mA max". Would my proposed solution
(using the signal lines as a sink for a small [< 25mA] load at 5V) work
for either CMOS or TTL signals? Both or neither? Thanks again.
You might want to use something like the ULN2803 8-section darlington
driver (open-collector) and 1K or so pullups to +5V.

At least that shouldn't blow anything up. :)

I seem to remember some chips that would sink 25 mA, but at the moment,
I'm drawing a blank. It shouldn't be too hard to research, though.

The OP said that his encoder will sink 25 mA, so he doesn't need the
ULN2803. All he needs is 5 mA pull-ups to +5V.

The OP also said that he doesn't have an encoder, but that he wants to
emulate one to drive the circuitry the encoder normally would.

Now, assuming that a '1' from the encoder was an open collector and that
a '0' was a saturated NPN collector-to-emitter junction, then what he'd
need to drive the circuit with could be 8 NPNs with their emitters
grounded, their collectors pulled up to +5V with, say, 1k resistors and
the collectors also connected to the inputs of the circuit.

N channel MOSFETS would also work.

You may want to look at "Gray Code"

Not saying that is what you're encoder is generating how ever.

Who knows, but for a $1.98 a watt it's a good deal if you want to give it a go. I know I could run my home office off a couple of
panels (laptop, printer etc.)Even having a couple would keep the lights on
in an emergency.

Especially at night.... factor in batteries and invertors and its way more
than 1.98.

For a laptop, printer and a couple of 15 watt compact florescent lights?
Hardly a huge expense, with 1000watt inverters $100.00 on ebay, a couple
of Sams' club deep cycle batteries ?

UPSs don't cycle their batteries much, unless the power supply is very

But even so I tend to get only three years out of my SLA UPS batteries.

You should investigate how much diesel goes into producing the uranium
to fuel the reactor. Uranium is very plentiful, but the yield is very
low. Eventually you make back the energy in producing the fuel, but
it's not like the fuel is free. Now if we had reprocessing plants, the
math would be more favorable, but reprocessing is very messy.

I used to be pro-nuclear until I read Dr. Helen Caldicot's "Nuclear
Power is not the Answer.". One thing I hadn't realized is nuclear
plants have to release gas periodically. The amount of radiation
released is very small, probably less than that of a coal plant, but
it isn't the closed loop system everyone makes it out to be.

OMG did you manage to read the whole thing?
You might want to read a few other books before you abandon
"pro-nuclear"

Yes, I read the whole book. Not sure when you went to college, but "in
the day" the BSEE required a class in thermodynamics. I got the
Babcock and Wilcox indoctrination. I was around for the claim of
nuclear power being so cheap they wouldn't meter it. I was also near
TMI when the accident occurred.. As time passed, much of the cover-up
of the event was declassified. [Shocker: the government lies!] I was
went from pro to neutral to probably negative. There is no solution
for the nuclear waste. Worse yet, there is plenty of nuclear waste
stored at the reactor sites that is not in any containment vessel.
They let the rods cool a bit before even considering transferring them
offsite, and we now know Yucca Mountain will not be opened.

Get the book and read the other side's opinion. Calecott's book is
well documented. It considers the entire "food chain" of nuclear
power. I didn't even bring up the power needed to enrich the fuel. It
is hard to get a number on this since over the years the centrifuge
technology has become more efficient. As you probably know, the
uranium for the WWII nukes was enriched at Oakridge due to the
availability of cheap coal power.

Basically, nuclear power isn't nearly all that it is cracked up to be.
I rather have more wind and solar, plus conservation. Sure, it chops
up little birdies, but hey, you need to break some eggs to make an
omlet.

Oh I have the book, I just haven't finished reading it. But I do have a
"issues" with some of what I have read so far. I also have "the new
nuclear
danger" and have a few problems with that as well, although I haven't
finished writing down the problems I have with it.

Umm, reprocessing would eliminate 90% of the "waste", including the
water-soluble Actinides and Lanthanides. Using the the Integral Fast
Reactor, (or an updated version thereof), that was designed
specifically to meet President Carter's request/order for a
proliferation-proof reactor design would perform the reprocessing on-
site. If I'm not mistaken, the "spent" fuel transfer could be
performed almost entirely by remote control.

But, of course, a Presidential Executive Order forbids reprocessing.
Why? Precisely because it is so cheap already that the United State
uranium mining industry is shutdown. Fuel in the Integral Fast
Reactor, (solid rods in a design that cannot cause a core meltdown, by
the way), can be reprocessed until 90% of their initial radioactivity
has been "burned up" in the generation of power instead the 9% that is
used in "conventional" light water reactors that throw away the
remaining 91% of the available radioactivity as (only very slightly
considering it very small volume) problematic "waste".

Well Helen seems a little short on numbers when it doesnt suit her. But
then, she also writes "facts" from unnamed dead people, which makes some of
her "facts" a little hard to check up on. She talks about Depleted uranium
in bombs... I've never heard of a bomb with DU in it (which doesnt mean
there isnt one of course. anyone?). And "Contrary to accepted norms of
wartime behavior, the U.S. attacked colums of retreating Iraqi soldiers-"
accepted?. by who? when? which war was that?

Nuclear power plants do occasionally have to release a tiny amount of
radioactive gas, (usually tritium IIRC), - one day I spent 10 minutes
getting some cleaned off of my new and statically-charged plastic
"bump" cap. But you're right, it is infinitesimal when compared to
the constant radioactive releases in the smoke from from coal-burning
power plants.

I like hydro-electric and wind power solutions, too. I especially
like smaller, individual-sized options. But I agree that those
massive dams could provide equally massive amounts of electricity for
many decades while causing less environmental damage that the coal,
oil, or gas-fired power plants required to provide an equal amount of
electricity.

For net energy, a quarter per peak pv watt is needed.

Even then, it would be many years after a quarter per watt for actual breakeven, owing to all the previously lost energy.

Huh? I usually agree with Don on these things, but here he seems to be confusing energy break even with economic break even. I a
perfect world they might be comparable, but I doubt if that is true in the real world.

I think what he wants to say is that energy break even is many years down the road,
possibly decades. And fixing and maintaining it might kill the small net energy surplus.
And before we get to break even we might have new, much better technology.

Who knows, but for a $1.98 a watt it's a good deal if you want to give
it a go. I know I could run my home office off a couple of panels
(laptop, printer etc.)Even having a couple would keep the lights on
in an emergency.

If there is enough sun to power the lights, you don't need them.


After 4pm six months of the year, yes I do need lights.


The solar panels are worthless for that use without expensive, short
lived batteries.
Cheap deep cycle batteries with a 15 year guarantee are available
