I've noticed that I pick up a lot of interference noise if get my ear too close to a trouper or certain electrical boxes. It would appear that the coil in the earpiece is picking up inductance from other power sources. To be honest, I'm not sure whether the noise is going out over the system or if it's just in my own headset, but it may not be just the wiring that acts as an antenna. Perhaps the headsets themselves can receive EMI.

On top of the all the old stuff, now cell phones. We were used to hearing radio cabs and police (the older Theatre Row theatres suffered particularly from Port Authority police). I teched 25 different dance pieces last week, and in the process we found that, no matter what sort of phone people had (ok, the sample was 3), those with Cingular as provider cause a horrible, rip-headset-off buzz if they ring within 2 or 3 feet of a beltpack. But only while ringing. Other providers did not seem to cause the same problem. So I turned off my phone, which speeded the tech up...

It probably needs a bit more than that to be really effective. Ferrite beads will provide an inductive element to the filtering. The jackpot answer, for a balanced input, is a small bi-filar inductor and two capacitors. Proper attention to earthing is also rewarding. Some years ago, I designed and installed our IR deaf-aid system. This lives up among the lighting equipment, and because I tried to design it to be bullet-proof, it has never had any RFI problems. Each mic has its own head amplifier, with a balanced input and the RF filter I described above. The amplifiers have enormous headroom, sending at 2V RMS, but capable of sending at 40V peak, in a pseudo-balanced configuration. The signals from the four mics are combuned in a wholly passive, transformer balanced mixer, and fed to the Sennheiser box. Overkill, maybe. But the only problem we have had was when some clumsy clown cut through one of the cables during a re-fit. You can see why I had a reputation for over-engineering, though.

(dragging this thread back on topic) I just spent a few hours working with it and I'm pretty pleased with it, primarily thinking of just those visualization tasks. Last show I did set for, the director absolutely couldn't get things without an artistic picture (set diagrams not sufficient) and I wish I had this then! (Especially since I'm not an artist, I'm a carpenter) - I'd have walked in with my laptop, flown him through the proposed set and saved myself some frustrating hours of discussions. I think it'll be a fabulous tool for visualization and discussions and playing around with ideas. Though I've read 'Drafting for the Theatre', I'm kinda in Frank's boat where I build what I design, so that my documentation only serves two purposes - to remind me what I'm doing and to communicate to the director, stage manager and actors. I don't need to include technical details, just the broad strokes and Sketchup seems great for that. If I had to send my drawings to a shop to be built, I think I'd stick with a real CAD program or with pencil and drafting board. And you can't beat the price! -cdr ------------------------------ From: FrankWood95 [at] aol.com Message-ID: <2e8.61008b8.318d2642 [at] aol.com> Date: Fri, 5 May 2006 18:05:54 EDT Subject: Re: Weight in Stage Drapes = Lead Tape vs. Chain In a message dated 05/05/06 21:47:54 GMT Daylight Time, delbert.hall [at] gmail.com writes: > Gold is very heavy and not toxic. Mercury is even heavier, and, being a liquid, accommodates well to irregularities. It is, though, rather toxic. I had thought of depleted Uranium myself, but it does seem to pose a few problems. Why, I don't know, since its major radioactive component has been removed. As, I think, are most heavy metals, if ingested. The trick is not to ingest them. After all, we have used lead for water pipes for many years with few problems. I do know of one, though. Glasgow's water supply used, in part, to come from Loch Katrine. This is incredibly pure, and very soft in terms of calcium bicarbonate or sulphate. Such water has a propensity to dissolve lead from the pipes, and the waterworks actually made it harder, artificially, to deal with this problem.

I think that communications are the problem. The director has to communicate his visualisation of the show to the set designer, assuming that he has one, and can. If not, it's the other way round. Either way, the two of them must be in agreement at an early stage. Then the LD gets involved, and not until then, You can't design lights in a vacuum. He will look at the designs, and at the director's wants, and consider how these may be reconciled with what is possible within his own constraints. Now, if any of these three has a communication problem, you may well have trouble. This can go down as low as exactly what colour to paint the set. I have seen a set designer resign over this.

I can believe it, given the long exposure time to heat that you have needed with the dinky soldering iron. Would it be possible to direct a small flame away from the housing onto the post? > These are supposed to be machine-soldered into PC boards using > standard very mild no-clean flux and soldering profile (a few seconds > in the solder is all they get). Yeah, right. With enough wattage, a few seconds is all that would be necessary. How about forgetting soldering completely? Drill and tap a hole in the post, then use the appropriate lug to fasten your wire to the post.

Quite possibly, but I don't think I'd trust these for any mass production. Too easy to have bare brass get contaminated. The Metcal iron is something like 50W (maybe more), there's a 1" long copper slug that's part of the tip with the self-regulating heater wrapped around it (it's all sealed in a stainless steel tube). I use it to solder solid copper ground planes all the time with the fat tip, takes a second or two to flow solder on the board. These are REALLY nice irons. >How about forgetting soldering completely? Drill and tap a hole in the >post, then use the appropriate lug to fasten your wire to the post. It's not THAT big and at microwave frequencies any extra wire would de-tune it. For future boards, I'll just make the board a little bigger and run the antenna as a trace on the board. For now, I've got them attached. At least there's no mechanical load on these once the board is in the box. For general info, the entire board is 1.125" x 2" including a processor that makes the Apple ][ look slow, the radio transceiver, buttons, coin battery, LED, misc. parts. -- Jerry Durand, Durand Interstellar, Inc. www.interstellar.com 219 Oak Wood Way, Los Gatos, California 95032-2523 USA tel: +1 408 356-3886, USA toll free: 1 866 356-3886 Skype: jerrydurand ------------------------------ Message-ID: Date: Sat, 6 May 2006 02:17:37 +0100 From: Clive Mitchell Subject: Re: appropriate metals References: In-Reply-To: In message , Jerry Durand writes >It would be SO much nicer if the factory would just tin the antenna >terminal before packaging them. > >These wet so poorly that I had one antenna fall out of the joint, >leaving a neat pocket in the solder.

Did you try cleaning the brass with a mild abrasive block? I didn't, I had someone else building the boards originally and they tried soldering all of them. You shouldn't have to do this with modern components, it's supposed to be out of the sealed bag onto the board, solder it, test it, and ship it. You don't even clean them anymore (too much pollution). I would normally have them machine assembled, but it was a tight schedule so we had to hand solder all of them (33 boards with 0402 size components). The only other problem with the rest of the assembly was the transceiver chip, the entire bottom is a ground/heat sink and it's a leadless package (all connections underneath), so that required cranking up the hot air flow a bit, but not even to half power. At least I now have enough boards to ship, the client goes live with these next week in Hawai`i (I should have asked about hand-delivering them :) ). -- Jerry Durand, Durand Interstellar, Inc. www.interstellar.com 219 Oak Wood Way, Los Gatos, California 95032-2523 USA tel: +1 408 356-3886, USA toll free: 1 866 356-3886 Skype: jerrydurand ------------------------------ Message-ID: <000e01c670ae$a786fd60$0600000a [at] BRUTUS> From: "Jon Ares" References: Subject: Re: Sketch Up Date: Fri, 5 May 2006 18:44:46 -0700 > Sketchup seems great for that.

It's primarily an alpha emitter, which is stopped by cloth or a sheet of paper. The main danger would be ignorant hysterical Luddites who will start picketing the theater convinced that the things are potential atomic bombs waiting to go off. The real health risk only comes from DU dust getting inhaled or ingested. Since DU is a rather mechanically robust metal, it isn't going to shed dust like lead will under the right conditions.

I was able to read the designs, however, which the director was not, and, quite painstakingly, explain them. Some people can't look at a set design on paper and produce any sort of imagery in their head. For communicating with them, a product that produces pretty pictures that are reasonably accurate can save a huge amount of time of folding pieces of paper into a 3d representation on the table. Heck, even directors who CAN read drawings would find this helpful - I think back to a few shows back where the set design was done months before the build, was built exactly to the design and the director still just then saw that it wasn't symetrical from side to side (there were reasons for it, to do with what had to occur backstage and it worked visually, but he never noticed, at all, on the 2d picture that it wasn't. It was fine, but it startled him, on tech weekend. I don't like startling directors on tech weekend :) He would have seen it right away, though, had he been able to fly through it. > Then the LD gets involved, and not until then, You can't design lights in= a > vacuum.

I'm sure as heck using it whenever possible now. Free, reasonably easy to use and quick - I went from installing the program to a nice 3d image of my last set in under 3 hours.

Basically I did it up in SketchUp first - you can draw/build elements to the correct dimensions, but you can also 'eyeball' it. SU also has dimensioning capability, so you can stick the dimensions on it to assist during the CAD drafting portion. Anyway, I save a bitmap from SU (then usually crop/resize it in Photoshop), and plop it down onto my construction drawing.
