Possibly the sightline problem didn't exist in the original theater.

 When I design, I don't design for the "cheap seats".  While I'm fairly sure
this will inspire flames, it is simply my way of facing the fact that almost
every theatre has "bad" seats somewhere.  I do not block these seats from
main action but the director might (and I would point it out).  Everybody

I'm in the flames with him.  I design for the worst seat in the house.
That person paid good money to see
a production and should be able to see "Batholemew" enter USR as well as
all the business that is done.  The actors should not have to be a third
of the way down and center to be seen.  The more cheap seats we sell,
they might attend more
Productions and have children that attend and maybe become Gold,
Platinum, Angel, InnerCircle, Old money, New Bling  or whatever big buck
seats patrons are called.   Not always possible, but sumpi' I always
shoot for. =20

Pillars in the house?

Ain't nothing you can do about that except ask when the tickets are
purchased.

Paul said, "I'm in the flames with him"?

Oh, no, I see; you did.

It's so confusing when people don't clearly indicate which is quoted text
and which is original.

Trey's quote of Paul showed up as blue in my email.  That seems
strange for a non-html formatted mailing list.

I agree that it is often difficult to tell what is quoted and what is
original.  And a lot of times people mis-attribute quotes to the wrong
poster.

Often your mail client will format quoted text and .sigs in other 
colors to make the content of the message stand out.  Thunderbird does 
this and I'm sure there are others.

From: Herrick Goldman <Herrick [at] HGLightingDesign.com>
Message-ID: <BF5887B2.780B%Herrick [at] HGLightingDesign.com>

Hey folks. 

I'm taking a show to Shanghai and when we spec'd power from the vendor
120/208v 200 amps 3 phase. He suggested we use 380V100A 3 phase. Now I'm
sure he's correct as he's worked this room before and it's his gear.

My question is...do I need to worry about my personal electronics? My
Powerbook G4 is auto-ranging, but is it auto-ranging enough? My graphics
guys all bring their PC laptops and Mac Laptops as well. Should I be worried
about this?  Is there a piece of gear I can spec (of reasonable size) that
will step down voltage for this gear?

I'm not too worried about my loads, it's a small show and I'm using all
"local" gear so the lamps will obviously be appropriate.

TIA,

_herrick

First thing to note is your computers are single phase (1 phase), so 
you will need the power split out for you.

Second, most auto-ranging adaptors work from 100-240VAC, 50/60Hz 
(some go to 400Hz for airplanes/military).

Before leaving the USA he bought a small  transformer unit from a local luggage

Some hotels that cater to US travlers have our style of plugs. Ask.

Caution on these adaptors.  There is a transformer type for small 
items like non-autoranging AC adaptors.  The transformers are 
normally limited to 25W or less, a laptop would smoke it.

There is also one that is basically a light dimmer permanently set to 
50%.  These are for heating appliances like blow dryers ONLY.  These 
will smoke electronic stuff plugged into them.

Advice, make sure all your travel appliances say "100-240V, 50/60HZ" 
on them and then just take plug converters.  You might still need the 
small transformer type for an electric tooth brush or cell phone that 
doesn't support 240V.  I'd avoid the dimmer type.

I'm pretty sure 220V is the common single-phase outlet in that region.

Next week I'm shipping an RC4 Wireless system to Shanghai, and they
requested a 220V transmitter.  And a show that toured through Beijing last
year with an RC4 system encountered 220V outlets.  (Unfortunately for me on
that one, they took a 120V transmitter with them.  Autoranging is coming
soon.)

Well, on my workbench here I have 220V, 120V, and 0-150V 
variable.  But, all 60Hz.  :)

Check the gear ratings. Most universal power supplies will handle either 120V 
or 230V. Some, though, won't. This is particularly true with power supplies 
built on the backs of local plugs. British 13A plugs and European hermaphrodite 
connectors all expect 230 V: presumably US plugs expect 120V.

The simplest way to solve the problem is with a 2:1 step-down transformer, 
suitably rated for the current draw. This can be built into a box, with a flying 
lead on one end, with the appropriate local connector, and a socket at the 
other with the connector you normally use. Some years ago, I designed a device 
which would accept from 120 to 300V, and deliver 120V. It was for the use of a 
film cameraman in Egypt. Film cameras depend on re-chargeable batteries, and 
the mains supply where he was lodging was rather variable. It depended on 
whether his neighbour had his cooker in use or not.

The supply was nominally 220V. With the cooker on, it went down to 150V; with 
it off, it could hit 280V. If he set the charger to 120V, it blew up when the 
cooker was off: if he set it to 230V, it didn;t charge the batteries when the 
cooker was on. I think that the supply in Shanghai will be more reliable.

This was some years ago, and technology has improved since then. Even then, I 
knew what I wanted to do, but lacked the facilities to build it safely. 
Winding small transformers, to handle 230V isolation, I thought unwise.

Much of it does. But many countries which were or are in the American 'sphere 
of influence'  use 120V, and 60Hz, too. It would be useful if a map were 
created, showing this.

AFAIK, most of Europe is on 230V, and most of America on 120V, including 
South America. When you go East from there, I don't know. Indis, Japan, SE Asia. 
Information would be valuable.

Naturally. You are in a country which uses 60Hz mains. I am in a 230V 50Hz 
area.

The advantages of 60Hz against 50HZ need a long discussion, and at 00.18, I 
am not prepared for this.

Most of Japan uses 100V which is why universal PSUs cover the 100-250VAC range 
and frequency is largely insignificant.  In some ways, things are getting 
simpler ;-)

The ones I've seen are dimmers, a diode would work for heaters, 
too.  Either will smoke anything with electronics in it.  :(

Got to keep that magic smoke inside the electronics, if the magic 
escapes, nothing works.

A good thing is with the new energy efficiency standards, most/all 
devices will become 100-240, 50/60Hz since it no longer costs more to 
do that.  Even our little AC adaptors for our DMX boxes will be all 
"universal" as soon as we run out of the case of transformer-type 
adaptors we have.

BTW, I am leaving for Canada tomorrow morning, I just received (and 
shipped) and order today.  Any orders while I'm gone will have to 
wait until Oct 4th.

In-Reply-To: <list-24748292 [at] prxy.net>

All,

We are nearing tech for our production of "Working". The director has
requested that the character Mike do some welding as part of his stage
business. We will have a cable with an electrode holder, a welding helmet ,
gloves, etc... as part of Mike's props. We do not own a stick welder so
don't worry it won't be a "live" welder. He will be welding on the backside
of an I-beam out of view of the audience. The students have been tinkering
around with sparklers, dremel tools, a strobe light and some other ideas but
so far nothing has been very convincing and or not terribly practical The
question I pose to the group is this: Does anyone have a fantastic solution
for the light and sparks that would be generated by a welder but would not
actually be a dangerous, fiery electric arc?

Any input is encouraged.

Thank you in advance.

    In Outlook Express, Each level of quoting is in a different colour.
(Selectable in the "Preferences" menu.) In the example above, Brian's quote
is green, and Steve's is blue on my screen.

    This is assuming that each quoted line starts with a "Greater than"
symbol (>), Two of them for a quote within a quote etc. These are placed
automatically when selecting "Reply".

Since nobody else has jumped in yet, here's a starter:

Hide a 12 volt bulb behind the I-Beam (maybe a projector-style reflector 
halogen) and a suitable power supply.. Make a series circuit with the 
power supply, lamp, I-Bean and the welding stinger.

When the 'welder' touches the electrode to the I-beam, it completes the 
circuit to the bulb and gives a realistic 'welding flash' onto his face 
shield.

Won't be a lot of sparks but small ones will be visible at the contact 
point.

Well, it's a start...

    But the local heavy equipment company probably has some all
terrain forklifts for rent.
    Having one full time professional driver on staff or on some sort
of all season contract who also takes care of your route planning,
permitting, loadmastering, etcetera is worth it.  That person can
do all the positioning and placing of the trailers, while your contracted
drivers just have to pull in to the location, drop off the box, collect their
signature and get going to their next haul.  They will know all the
byzantine rules and regulations that will trip you up otherwise.  Large
reduction in hassle factor.  I also advise being prompt in payment, and
low hassle with your contract drivers.  If you are a PITA to deal with,
word gets around and you start finding it real hard to get good drivers.

    Add to that circuit a small fan that sucks smoke from a concealed
fog machine into the beam of the light.
