Yikes!  This will result in about 170VDC!  Not only is it a
bit more dangerous to deal with, but standard bulbs run this
way last a very short time.  But they'll be pretty efficient!
You must have a pretty large rheostat handy, or else you are
playing with fire.  There are far more efficient ways of
dealing with voltage conversion these days.  Why has nobody
mentioned switching power supplies, besides cost?

No, nobody's missing the point, but you seem to have missed a lot of the
discussion.  The people touting these flywheels are talking about a car with a
range of 600 miles, though they plan to divide it up among 20 flywheels,
something that wasn't mentioned in this thread until a couple of days ago). 
Now, we've been talking about the energy required to drive a car 100 miles at
freeway speeds, and one of the more fuel-efficient cars on the road today, to
boot.  I.e., we've been talking about roughly 2 gallons of gasoline.  Now, if
the people touting the flywheel technology are really trying to mislead us and
they're talking about a 600 mile range at an average speed of 15 mph, then yes,
you might have a point.

=Car designers aren't completely stupid, you

If they're talking about stop-and-go driving, why are they talking about a

Yes, we know that.  That's why we've made generous allowances for the relative

the EV was 100% efficient.  You *REALLY* should have read more of the thread
before jumping in to prove that you haven't been following it.

Hi All,

Recently I learned that a friends mother suffers from Hodgkins (sp?)
disease.  As a result, her motor control has become very poor and she is
having alot of trouble changing channels on her tv set.  The problem is
that her remote control (supplied by the cable company) only gives the
user a certain amount of time to press the required numbers to change the
channel (IE 3 & 8 to change to 38).  As a result of her condition, she
cannot enter the numbers quick enough to operate the remote.  There are
only three channels which she actually watches with the highest numbered
one being 38.  Does anybody have any suggestions which would allow me to
build some sort of circuit which would allow her to select any one of
these 3 (and only these 3) stations with the press of a single button?  
was thinking of one of the older wired remotes which had a series of
buttons along the top with a seperate button for each channel but I'm not
sure if they go up to 38.  If they do, I could probably put together a
small wired remote which would give her three large buttons (one for each
channel) to work with.  Any help would be greatly appreciated.

You know, every time I hear someone say "where does the Constitution

country.

I don't have to look to a piece of paper to find out what rights I
have, you see, I have *inalienable* rights. I have rights because
I'm human. The Constitution doesn't give me rights, it merely
delineates certain extremely important rights. The Constitution is
the government's license from the people to govern. It spells out
exactly what the government is allowed to do. And as it says in
the Tenth Ammendment "The powers not delegated to the United States
by the Constitution...are reserved to the States, or to the people."

In small words: I don't have to prove I've got a right, you have to
prove I don't.

In small words: If the Constitution doesn't say the government can do
it, it can't.

In small words: If we the people did not give a power to the government
in the Constitution, the government can't do it.

So, the proper question to ask yourself when it comes to rights people
claim that are not specifically spelled out in the Constitution is not
"Where does the Constitution say that" but instead "Where does the
government get off telling me I don't have that right".

The voltage rating of a fuse does factor into the fuse's circuit

LITTLEFUSE 3AG 2A 312 fuses here on my desk.  They are single link
tubular glass cartridge fuses of the type one would find in a radio
receiver or computer power supply.  The barrels are marked "2A
250V."  The package notes:  "SC  10,000A 125 VAC  100A 250 VAC."

I checked my catalog for 3AG type fuses.  There's no mention of the
overload characteristics for 3AG; only, "fast acting."  For 3AB,
which are ceramic barrel, the characteristics are blow time of
110%, 4 hour maximum; 135%, 1 hour maximum; 200%, 15 second

Maybe you could just measure the road horsepower rather than believe
Portch propaganda.  Here's the drill.  Drive at 70 mph on level ground.
Push the clutch and hit neutral.  When the car hits 65 mph, start a 
stopwatch.  When it hits 55 mph, stop the stopwatch.  You now have the 
beginning and ending speed and how long it took to change.  Given the
car's weight, you can calculate how much energy was lost in the process
of decellerating.  I'll let you figure out the math.  It's Physics 101
stuff.

Hint:  Cars I've measured require road horsepower in the range of about
12 to 25 hp @ 60 mph.  Since the Portch rolling wedge is far from 
aerodynamic and uses gumball tires, I'd certainly not expect a figure
near the low end.

BTW, I liked your comment about having blind faith in the engineers who are
designing flywheel batteries.  Reckon you could help bring some of that
to my field, nuclear energy?

I've measured several 286 and 386 machines with a wattmeter.  The
average power consumption is about 60 watts at idle (no disk
seeking) and about 10 watts more whille the disk is seeking.
Monitors draw about 60 to 100 watts depending on how much of the
screen is illuminated.  So figure worst case 160 watts if you leave
the monitor on all the time (not an especially good idea).

Presuming electricity goes for about 10 cents per KWH, That would
be $11.91 in a 31 day month.  If you shut the monitor off for all
but four hours a day, your cost would be about $5.71 per month.

You might look more in the direction of using a full wave

You'll wind up with about 140 volts DC and that through a
rheostat should work on a standard light bulb ok. (I think).

This is kind of like saying that a wind up watch takes 24 hours to wind.
You can add X ammount of energy in Y ammount of time to the flywheel and
use X (minus a slight ammount for bearing loss) in Z ammount of time.
ie.  Charging time and dis-charge time are as unrelated in the flyweel
as charging time and dis-charge time are in a lead-acid battery.

This sounds like a temperature-drift  or an adjustment problem in
either  the  main  power   regulator  circuit  or  in  the  extra
high tension (EHT) generator/horizontal deflection circuit combi-
nation.  The sounds probably come from sparks arising from inade-
quate insulation in the extra high tension circuitry,  especially
in  the thick cable that is attached to the tube at some point on
its side.  This cable carries approximately twenty-five  thousand
(25000)  volts  to  the  front inner coating of the picture tube.
Bare conductors carrying this high a  voltage  must  be  kept  at
least five  centimeters  away from any other  conductor  to avoid
leakage and sparks under a wide range of air moisture levels.

It seems that the EHT is not adequately  insulated,  or  the  EHT
generator is misadjusted such that it generates more voltage than
it has to.  In either case, sparks and excessive leakage will oc-
cur.   The  sparks produce ozone, which is a poisonous gas with a
garlic odour.  Leakage through plastic,  bakelite,  and  phenolic
materials used for insulation, on the other hand, produce organic
gases with typical odours.

The remedy is to have a repair technician check the  EHT  circuit
starting  from  the  tube,  towards  the  EHT  rectifier, the EHT
transformer and the horizontal deflection/EHT  driving  electron-
ics.  The  main  power  supply may have to be checked, too.  They
may  be  found  to be "fubar" (fouled up beyond all recognition).
Do  not  attempt  to  repair it yourself if you do not know  what
25000 volts stored  in  a  TV tube can do,  not  to  mention  the
various  voltages up to 250  VDC  travelling  around  the printed
circuit  boards.  The  latter  are even  more  dangerous  because
they can supply larger currents.

(To avoid such problems altogether, use a LCD pocket TV :-)

I'm just getting started with the ICS and have already lost my KICS
manual, so maybe I'm missing something simple here.  (Anyone have
the number to use at Motorola to order another manual?)

Whenever I trigger an external interrupt (using IRQ or low Port A pins)
I get stuck in the interrupt handling routine.  I'm using RTI, and have
even tried CLI, but as soon as the instruction is hit (in the ICS), the
PC jumps to the IRQ routine.

Note that I don't go into the IRQ routine until I cause a valid trigger,
and the IRQ pin (onscreen) does toggle from 1 to 0 and back as I change
its level.

Also, when running the Paced Loop Program I get extremely long delays
between LED blinks even with RTIFs only counting down from 1 (instead of

Thanks!
