Actually Dave, I think he means the part where I referred to Frank as a potential Child pornographer just because he has a camera and the ability to use it. Anybody who has a camera and knows how to use it could become a child pornographer, anybody who owns a firearm could become a murderer. I hoped the people who were suggesting that guns are only for killing, or that target shooting is just murder practice, might find the parallel to their own potential for pornography to be thought provoking and slightly offensive, just as I felt about the presumption that I was a potential killer. I am sure that Tony and Frank have never produced that sort of photograph, but not because they lack the tools or the ability, it is because they HAVE a Moral Compass. People who own cameras do not see them as a tool for evil, temporarily put to non-harmful use. When somebody uses a camera for such a thing, we hate that person for what they did, not for the tools they misused, and other people don't look askance at us because we are tarred by the same brush for just owning a camera. Is it because we all own cameras and understand them, but often people who make claims about guns do not own them, or understand them. That same Moral Compass is the reason I don't shoot people. Killing is wrong, the mere possession of the tools and the ability to use them no more makes me a person likely to use violence to solve my problems, than it makes a camera owner into a pornographer. And, lastly, take a look at the evolution of this thread. The initial post was pretty egregiously off-topic and a jingoistic and alarmist broadside designed to alter perceptions of American gun owning voters. The initial response from Americans, was largely that the post was dumb, and that the political party that it was trying to support posed more of a real threat to our rights as a whole, and the safety of the planet in general, to be allowed to continue in unchecked power. There was a good discussion going back and forth about rights, regulations, the US desire to poke into other nation's affairs. Sure it was off-topic, but most of us can use a delete key if we so choose, those who can't figure that out may seek help from Mr. Babbie. Then, instead of letting the thing die, our British Friend, Mr. Wood, started blathering on about many things on which he has NO knowledge including 1770's gunsmithing, pistol shooting, 21st century electronics design.(Is that a surprise or what?) Actually, If you delete all of Frank's posts, and the reactions they generated, the thread is quite civil and well reasoned. I guess this means I'm killfiling Frank too.

Yes, but they only work in this reality. We need to find a "loudspeker" for the alternate reality FW is in. I did post a link to digital microphones, it does seem like a good idea if you can get the dynamic range right and the cable is cheaper than plain old XLR mic cable and the mixer isn't tons more expensive and it doesn't break easily... ------------------------------ From: "Joel Harari" Subject: RE: Snow Machines Date: Sun, 22 Oct 2006 10:11:48 -0700 Message-ID: <000001c6f5fd$2938b0f0$6601a8c0 [at] Tigger> In-reply-to: Oops, forgot the subject line.

Something similar to 5 old flashbulbs going off. Stobes aren't > cutting it as they have a capacitance charging time. Get a real strobe. I can get 60 joule flashes at the rate of 10 flashes/second - or even faster. In Special Effects mode (requiring the HO-1 lamp and 190+VAC) the continuous duty cycle is 26%, which means it can be at full intensity for that percent of elapsed time without a cooldown. So at 10 flashes/sec, the flash duration can be .026 seconds. There are strobes with much higher ratings - but I got mine used on ebay for roughly $175 each. Bill Bill, that still doesn't work for us as we need the flashes to be timed at different intervals. For instance: flash one on the 0 count flash two at .1 seconds later flash three at .5 seconds later flash four at .1 second later flash five at .2 seconds later.

I googled "didital >loudspeker" and didn't get one single hit. The worst thing about digital loudspeakers is that they only produce squarewaves. It takes all the subtlety out of little orchestral moments. On the other hand you do get speakers with digital amps built in. As for the microphones. You get USB studio recording microphones these days. They plug directly into the computer without going via a sound card.

The Strand Prelude 650W range did this to me. While the lamp tray comes out easily, the lampholder is spot-welded to the tray! Beat that for hard to service. They want you to buy a whole new tray. Fortunately, a small, sharp wood chisel will break the weld. It still requires a workshop with a vice, a drill to remove the pop rivets which secure the reflector and to make the holes for the screws which secure the new lampholder. Not to mention pop rivets, crimp connectors, nuts, washers and screws, and the necessary tools. And, of course, the tester to certify it before it goes back into service.

This was, I think, the first class D amplifier to hit the market, and digital it is not. What breaks your back is the weight of the mains transformer. Switch-mode power supplies provide an answer, especially two-stage ones. The trouble for a one-off is sourcing the transformer for the first stage, which provides the mains isolation. I designed one once, but had to use an iron transformer up the front. Winding a ferrite cored transformer to provide this is beyond me to do safely.

Well, if you Google "stagecraft," the second URL that comes up is for Noah's Stagecraft Mailing List page. From there, it doesn't take much to get to the members' list, and if your e-mail address is on it, it's accessible to legitimate and not-so-legitimate inquiries alike.

Have you tried DMX strobes? If you use multiple strobes, you can build this as an effect/cue in your board.

Fair enough. Digital audio is commonplace, these days. The Hi-Fi buffs have their own views on it. It is the transducers which resist digits.

They have a known problem with cracking lenses. The new design has the lens mounted to the outside of the lens door. You can buy the new doors. " Yes, I could buy new doors. But why should I. This is a fixture rated at 1kw and the lenses were cracking beceause of poor design when used with a rated lamp. I was within the warrenty period when I first reported it and all Mrs. Altman (Yes, she was still alive at the time) could do for me was the insulators, which I had to pay to install as well as footing the bill to replace the lenses - and I did ask and she said no. I recall being a bit peeved at the time, especially as I was having issues at the same time with my 4.5" zoom ellipsoidals, whose rear lens would crack when used with an EHG lamp, and again, the fixture was rated at 750w. Mrs. Altman suggested then that the fixture lamp alignment was set to too hot. That got my Irish up. Altman (and I) have been lucky that a lense didn't break while hanging 20ft. over someones head, causing an injury, as it's my opinion that they should have maybe made an effort to get the word out that there's a problem. FWIW, this was also a topic of discussion on Control Booth.com last year, so this may well be a known issue, and I can say that I lose faith in a company when I first read about a re-design on this forum - 20 years later. The Consumer Products Safety Commision would have a field day with this one !. We have since downrated all our 1KAF's to 500w. Oh, did I mention that the beam edge on the 1KAF is this butt ugly semi-hard brown edge when flooded all the way out. This is the only fresnel that I've ever had to add R132. "I don't think the replacement lenses we purchased about a year ago cost anywhere near that amount". The Production Advantage website lists the 1KF 6 lense at $58 and change.

Sure it does. I didn't mention that these are DMX controlled. It is easy to create an effect on the light board to produce flashes at varying intervals, down to the minimum time resolution that the board can manage. I do that all the time with my strobes. I don't think you could do it easily with a manual strobe. You would need some rather complicated timer electronics.

The first I ran into it was in the early 1980's, it wasn't called Class-D then, nobody really had a name. It was the output of all CVSD audio playback chips (used heavily in things like NATO walkie-talkies). Kind of interesting idea, you just transmit the PWM data directly as a serial stream. After that came "1-bit" D to A converters for CD players. The really high pulse frequency makes it really easy and cheap (REALLY cheap) to filter the output. Finally someone started calling them Class-D, not sure when. Oh, and depending on your definitions, Class-D may NOT be digital if you don't count the "0 or 1" state of the output drivers. But, there are chips that go from a direct digital input (USB or serial audio) to a Class-D output, no analog anywhere in the chip. ------------------------------ From: FrankWood95 [at] aol.com Message-ID: Date: Sun, 22 Oct 2006 18:42:28 EDT Subject: Re: 1KAF Fresnels In a message dated 22/10/06 23:27:41 GMT Daylight Time, ladesigners [at] juno.com writes: > I assume that the bench-testing includes the use of VERY-sensitive > GFIs, and that the GFIs are tested and recalibrated/replaced often.

The input data to the CVSD (Continuously Variable Slope Delta) modulation chips was a single bit stream with variable clock frequency, but the output was relatively analogue but with quite sharp steps that had to be filtered out to avoid the clock frequency affecting the audio too much. Amazing level of speech compression though. The earliest talking arcade games used this technique to cram huge amounts of speech into modest arrays of EPROMs with that characteristic stepped melodic speech.

The early variable frequency motor drives suffered the same fate but now it's pretty hard to kill them. Both MOSFET and IGBT technology have advanced to the point of being very robust indeed. As for Clive Sinclair. If it wasn't for open minded inventors we wouldn't have some of the technology we have today. I wonder what sort of computer you'd have in front of you now if he hadn't kick started the computer revolution with the very affordable ZX80 and siblings. Even his bold failures like the C5 had bizarre knock on effects in other industries with the availability of mass produced high torque DC motors having a very positive effect on early robot construction.

I know the phenomenon you're talking about, and it's certainly a low-frquency audio something-or-other, but are you "hearing" it, as opposed to feeling it vibrate in the earbones - yes, there's a difference. It are definitely a different sensation than "sound." Or is it?

Giving the OP the benefit of the doubt, I just supposed he knew (from the many, many times that it has come up here, and on the deck all over the US) that a very large portion of stage technicians enjoy guns as the great little machines that they are. Most of us are gear geeks, and a great flashlight that'll set balsa wood on fire or illuminate a single word of the script from the grid is just as cool to us as a machine that'll throw a small projectile a great distance with incredible accuracy. The fact that it'll make a huge noise and flash and sometimes a buncha smoke is just a bonus for us. When it all boils down to it, this is why we likes 'em, and we defend em so we get to keep playing with them. Responsibly, of course. If that wasn't his intention, then there was absolutely no reason what-so-ever for it to be here. I don't want to know, though, I just want to think the best of everyone. OTOH, there was quite a bit of misinformation being tossed around, and when that happens, regardless of the topic, we, as a group, are pretty much compelled to expose and correct it. The fact that it was guns and emotional just got under a lot of people's skins. As I pointed out, the only other topic that might have the same reaction is the discussion of religion. This discussion has followed quite the same pattern that most of our off-topic discussions do, other than the emotional reaction that a few people have when discussing guns and/or religion. We get off topic. We do. We should, as adults, be able to deal with nearly any topic that comes into our sphere of influence. Please don't make us get a list of things that we aren't able to discuss rationally. This, like any other topic, *can* be discussed rationally, it just requires that we don't respond emotionally or irrationally. Either that or this group isn't capable of that. I'm just beginning to wonder which it is. I'm leaning hpefully towards the former. Arright, you know you guys have been screwing up when *I'm* the voice of reason...

Does anyone know if there is any type of group
interview/audition for high school students wanting to
go into tech programs in college? A coworker that also
teaches at a local high school just asked me this
question. He had a student go to something like this
for acting programs, and was wondering about his tech
students. He doesn't want them to spend the money and
time away from school traveling to different colleges
if there might be an easier way.
I know that there are multiple events like this for
summer stock and grad schools, but I don't know of any
for undergrad. If such a thing exists, I'm sure
someone on the list will know of it.

Thanks,

I got my first real theatre job from the Theatre Auditions in Wisconsin when I was in high school, as well as my second one in college. Its been many years since I was there, but there were always a fair number of potential employers interviewing for tech positions.; the last time I was there I remember my day pretty much filled up with interviews. The workshops they hold the day before were always helpful as well. Though there was only ever one for technicians [a personal and group critique of your resume/portfolio]. I always learned something from both those critiquing and those being critiqued. -- Sincerely, Andrew Vance Lighting Designer atvanceld [at] gmail.com ------------------------------ Message-Id: <3.0.6.32.20061022190745.00c58ae8 [at] pop.west.cox.net> Date: Sun, 22 Oct 2006 19:07:45 From: CB Subject: Digital electronics (was: Re: a political stance) > Why?
