At 10% efficiency, you'll get about 100 watts out of a square meter of

The term "animusic" is also soemtiems used to describe "musical animation".


BTW, to animate simple piano roll notation, it's simple to cluster the piano
roll into one track and assign different colors. I don't think Sonar Home
Studio 6 does the *video* capture (tho' I never gave any thought to it

even be doable using Flash, or even JavaScript. One YouTube example used

making them a less sensible option.

When millions of electric cars hit the road, the cost of electricity will rise accordingly
due to lack of supply. Can't build all those nukes over night.

available.

Any advice/recommendations/warnings?

Who knows - CNN and MSNBC have been talking about the way the Campaign has
kept her pretty much isolated aside from having her basically repeat her
Convention speech here and there, and they've been speculating as to the
reasons - soem suggest it's to "bring her up to speed" on national and

others havespecualted it's to keep the media more occupied with speculation,
so there is less time available to research her and report on the actual

I think I included this link in another post - it's anon-partisam outline

speculating about Palin, and wasting time commenting on stupid stuff like her
"fashion style" => , the elss time is available for disseminating *real

So, I've heard nothing about when she might start giving interviews, other
than that nobody knows and no hints have been given - if my own misgivings
are correct, the Rep. campaign will keep her as isolated as possible for as
long as possible, and avoid having her give unscripted interviews for as long
as possible.

Not necessarily. Given that oil is a finite resource, and it is already

Fair enough.

It will be long years before electric cars enter into mainstream.

Especially if people listen to those who find any and all "reasons" to not
bother trying anything new, rather than looking for ways to make renewables
more feasible. Meanwhile, compressed natural gas can be, and is, used as
fuel for vehicles, and people are already working on establishing/expanding
the required infractructure. It will be a bridge between the curent
petroleum-based culture, and a renewable-energy culture.

Sure the price will drop as they automate the assembly of the vehicle.
That's what gets me about regular car prices, alot of the car is put
together by machines these days. Yet the prices don't seem to come down
much.

That's because so many extras are added on to keep the price, and
profits, high. I've occasionally wondered what my old Capri 2.0L would
cost these days. No central locking, no power steering, no powered
windows, no aircon, no super surround sound hifi, simple engine, 37mpg
etc.

That's why they stopped making the Saturn SL1. Larger profit margins on
SUVs.

OK, my 2002 does have air conditioning and power steering

What amamzes me is that the Infinity I35 (whcih they also stopped making) is
a fairly large car, very nice interior, comfortable, has more than enough
"zip", and gets about 26MPG mixed city-highway. Meanwhile the much smaller,
cramped, delayed-accelerating, poorly-handling, hard-riding G35 that I had as
a loaner didn't even reach 20MPG. I was looking at new cars becasue I'd
thought that, Surely there are now ones that get better MPHG than my SL1, but
amazingly, even the teensy cars weren't any better (I get about 30MPH mixed,
and teh tiny ones max at about 35 mpg *highway*, but there is no way of
telling what the Mixed mpg works out to be).

So I'm not getting rid of my SL1 any time soon...

Phil Allison"

So I'm ready for the next stage solution. The first time I read Jim
Williams article on the Weinbridge oscillators (this is also in one of
his books.) I didn't quite "get" the integrator FET solution to the
gain control problem and the light bulb looked like such a simple
idea. (I also loved that it was the begining of HP) But I've
advanced since then and am now ready to try this other circuit.

-----------------------------------

How about a new and much better oscillator circuit ???

A simple one that does not use bulbs or strange JFETs to stabilise it.

One that can be made with a single quad op-amp ( eg TL074 ) and no special
parts.

One that exhibits no amplitude bounce when adjusting the frequency or
range
changing.

One that has constant THD of 0.15% from 2 Hz to 10kHz.

One that has flat amplitude ( +/- 1% ) over that same frequency range.

------------------------------

See ABSE ( alt.binaries.schematics.electronic ) for the schem of a " Low
Distortion Oscillator " design I developed 20 years back and was published
in Electronics Australia magazine in February & March 1989.

The circuit use two all pass filters as a "phase shifting" oscillator with
harmonic distortion cancellation ( IC2b). As shown, the output level is
2.5
volts rms - which can easily be increased. Just ask me.

Ignore thermistor TH1 which for very low THD only - the 4 diodes and
resistor network is all you need.

Tuning is done with a standard double gang pot with both halves grounded
at
one end. A simple Schmitt trigger square wave converter is there too, if
you want that.

BTW: This the device you are working on ?

http://www.teachspin.com/instruments/signal_processor/index.shtml

Ah you found one of my babies! yup that's it.

Well I don't want to change the fornt panel so I need tuning with a
coarse capacitance range and fine dual ganged pot range.


** Which is EXACTLY what the design has.


I'm slightly
worried about the harmonic distortion which "screws up" the phase in
the phase shifter.


** Huh ???

The other potential problem I would have with some
"switched" oscillator is the radiated noise.


** What the heck are you on about ?

There is nothing "switched" about the circuit - just a TL074 operating
linearly.

Operation is very similar to a Wein bridge, without all the drawbacks.


(I'm not sure what your
oscillator is, but you mentioned a comparator.)


** I did NOT mention any comparator !!!!

Have you seen the schem on ABSE or not ??

http://www.usenet-replayer.com/cgi/content/framebanner_3?http://www.usenet-replayer.com/3/8/0/8/1220798083.149.jpg


I would like to keep
the "leakage" of the oscillator into the front end down to the 10 nV
level.... that's about the noise voltage level of the preamp.


** At least give the schem a look - pal.

Cos you sound like you are 100% off with the fairies.

Its a toy, You need something like this...
http://www.bikeparts.com/search_results.asp?ID=BPC307590

I think I achieved not too much less than that with a hot-rodded Cateye
HL-EL 5200.

That is a maybe $40 4-AA LED light with a Luxeon.

So...

I use NiMH rather than alkaline. The lower voltage causes additional
need to hot-rod the driver.

There is one resistor - I somewhat remember being 15 ohms. I replaced
it with two 10 ohmk 1/2-watters in parallel.

I painted the heatsink with a Sharpie to inctrease its ability to
radiate heat. (Other exreriments since then gave me results that outright
paint works better than such a thin coating.)

I replaced the LED. If I did that now, I would use a Luxeon
K2-with-TFCC "emitter". However, I used a Seoul Semiconductor P4. I had
to add spacers somewhere (I forget exactly what and where), and I had to
omit the LED "clamp" and glue the LED onto the heatsink with epoxy, since
the P4 has its optical center in a slightly different location than a
Luxeon does.

Result: I widened the beam about 50% and roughly doubled its intensity.
The souped-up HL-EL5200 makes a heckuva flashlight - gives a 4-D-cell Mag
a run for its money.

The effective intensity outdoors at night at distance was increased
maybe only 40-50%, since the Seoul Semi P4 had a lower scotopic/photopic
ratio than the Luxeon that I replaced with the P4. Nowadays the Luxeon
K2/TFFC is available.

OK, so it's not quite half a 20 watt halogen. But then again there is
the Osram Ostar LE UW E3B-PZQZ-4C8F, available at Digi-Key. That one
requires a substantial heatsink!

Yes, I suspected the crimp at the filament. But I examined some
other bulbs under the microscope and couldn't find any
difference.

Did you try cutting off the glass and measuring the resistance
right on the filament, or is there something about a tungston
filament that makes it hard to make good contact?

Hi Tom,

I was considering that, but it would disturb the connection so much
it would be hard to prove the results meant anything. Also, there
would be no way to restore the original condition to prove we could
re-create the original problem.

As mentioned, I did examine the crimp under a microscope and
compared it with normal bulbs. There wasn't any difference that I
could see.

The curious thing is all the Sylvania bulbs behaved exactly the
same. They are normally open, and applying 120VAC causes them to
read the same. They all read 46 ohms within 1/2 ohm. It is hard to
see how a loose connection can be so consistent in all the bulbs.

Another problem is there are two crimp connections in each bulb. If
it is the crimp, which one is doing it? Then, if it is one, why that
one and not the other?

So we have to design an experiment that analyzes something we cannot
reach, and tells us why the bulbs act this way.

I was thinking of applying a fairly low frequency, low amplitude
signal to the connections to see if a capacitive probe could pick it
up. Then trace it until it stops. That would require a narrow-band
receiver to track a low-level signal from the probe. So I have to
get my HP 8566 cleaned and give that a try.

Best Regards,

Interesting. Would colors look more true if, in the lamp design, one

Oh, so then, it wouldn't offset the "day-glo red" effect

Although you've gotten me thinking about a possible variation on the
"flickering candle" LED lights- since a candle flame actually consist
ofa progression of colors (basically, very small blue core, large white
band, moderate yellow band, and small red band), I'm wondering wbout
setting up a series of flickering LEDs in that sort of pattern. That's
just off the very top of my head, but I'm trying to picture whether it'd
look interesting- enough to put more thought into it.

I have looked at candle flames enough, and it appears to me that over
99% of the light is from the whitish/yellow-yellow region, in the form
of close enough to blackbody radiation at color temperatures in a range
mostly within a couple hundred degrees of 1900 K.

If you put random noise through a narrowband filter centered around 6
Hz
or so and have that modulate the brightness of a 1900 Kelvin source,
that's already most of the way there.
The next refinement would be to
modulate the color slightly (maybe 50 Kelvin) - with color temperature
varying inversely with brightness, maybe not exactly 180 degrees out
of phase from brightness.

- Don Klipstein (don@misty.com)

Er, that's a bit advanced for me...I'm just starting to teach myself a little
bit about "555 timer" =:-o

But could you do all that modulating with an LED as the light source...? I
thought they had fixed colors and could only get brighter or dimmer with
changes in voltage. It'd be cool if you could actually modulate and LED like
that.

I think that the flickering effect would be especially attractive inside of a
clear-textured glass enclosure/construct.

Do you have any suggestions for a notch or lowpass filter to kill the

** Antenna pattern is more likely to be successful in such a case.

Point the back end null at the 107.9 tx.

I believe it is causing intermod

** FM does not suffer from such an effect.

Worst case scenario is you hear both Txs at once.

I am at work now and will happily look over the circuit. You
mentioned a double All Pass phase shifter, which I see as the first
two op-amps, but how is the loop amplitude controlled? What stops the
oscillations from growing with out bound? OK I think I see when the
four diodes start to conduct the gain around IC2a is reduced.

** Yep - it only take the slightest bit of diode conduction to do that
too.

Such limiting is nothing like as complicated as using a feedback control
loop.

Cos, unlike such loops, is both instantaneous and 100 % effective.

IC2b performs the magic of removing the distortion.


If I leave out the thermistor then a signle RV2 pot will adjust the
amplitude. I'll try bread-boarding the circuit and see what I
think.


** Be amazed.

For more output level, best use more diodes or ( matched) low voltage zeners

..... So I started looking at building my own
oscillator and when I found the Weinbirdge I "fell in love". (Does
this make me a farie??) So the romance is now winding down and I'll
again certainly look at your oscillator. And agian sorry for getting
you upset.

Speaking of things that gestate, how long before Sarah Palin's goes
on the Sunday Morning talk shows?

-mpm

Who knows -
[snipped due to really bad text wrapping]

I heard she was going to start giving interviews after her oldest went
off to Iraq.
So I guess it isn't country first. It's her son, then country.

Fucking Republican. 360 Million Americans want to know more about her
before they vote her ass into office 6 weeks from now and she can't
even get a few moments in front of the damn camera. And it ain't like
the networks aren't lining up.....

She lost my vote right there!
Nevermind I would never vote for that old fossil McSame anyway.

I did hear on CNN last night that she is supposedly going to grant a 2-day
"walk and talk" interview to, IIRC, Dana Bash this Friday and Saturday,but
nothing was firm as of that time.

Meanwhile, from all I've seen and hgeard, it seems to me that choosing her
was a stunt - aside from supposedly trying to garner Hillary supporters
(even tho' Palin's beliefs and politics are anathema to Hillary, so thwe
argument doesn't convince me), I'm inclined to think that they picked
Palin specifically because they figured people would be kept so busy
trying to find out something, anythin!, about her that they'd not have
time to look beyond McCain's rhetoric and get the details, the actual
info, re: what *exactly* (as opposed to broad general statements) he
proposes to do, and by what method.

Also, part of what they're doing is attacking valid questions and doubts
(given the lack of info) with snarky puerile comments that are supposed to
make it seem that merely asking valid questions makes one some sort of
"enemy of motherhood".

This cynecism is merely compounded by the sequestering, the secretiveness.


I've listened to interviews with McCain, Obama, and Biden, so I have
rather a good sense of how informed they are, how familiar they are with
things like world events and economic principles; I've also seen them
think on their feet. All I've heard from Palin is repetitions of the
convention speech, with a few minor additions.

I'm trying to remember, how aloof was Quayle???

I seem to recall that part of Quayle's problem was that he *did* put
himself 'out there" in the public eye. Remembering his gaffes, I can only
assume that the cynical secretiveness is intended to only allow her to be
in situations that the Rep. campaign controls, so as to try to hide any
negatives.

Maybe they're teaching Palin how to spell potato(e)??

Heh, potato / potatoes

On the up side, Palin *is* about as dynamic a speaker as was Dan Quayle...

OK, actually I'm just stirring up shit.

It's not "stirring up shit" - it's just asking valid questions that should
be asked about *any* candidate.

But I do wonder if any Repubs out there are miffed about her TV
absence.....???
What about it?? Anyone?

Hmmm, I can't answer for partisans - I'm an Independent, no party
affiliations. But I also wonder whether *all* Republicans are merely
accepting the hoopla without asking any questions. Neither pary has a
monopoly on partisanship.
