Right, but there's no exemption for when they're installed in a car. So, owning a car with airbags means you own 1.4 explosives with all the storage and use permit requirements. Our ATF inspector agrees that rules like these are based on "you know what we mean" when they should spell things out. It DOES make it easier to arrest someone you don't like, there was a case this last year where self-lighting charcoal briquettes were entered in evidence as explosive materials. This was based on any mixture of charcoal, sulfur (in this case natural trace amounts in the charcoal) and an oxidizer (in the self-lighting mixture) being defined as black powder. ---------- Jerry Durand Durand Interstellar, Inc. 219 Oak Wood Way Los Gatos, California 95032-2523 USA tel: +1 408 356-3886 fax: +1 408 356-4659 web: www.interstellar.com ------------------------------ Message-ID: <20041221193706.28073.qmail [at] web20828.mail.yahoo.com> Date: Tue, 21 Dec 2004 11:37:06 -0800 (PST) From: Steven Hood Subject: Re: triscuits In-Reply-To: Looking at the ref that Murr gave for the Yale version, I'd have to chime in that there's a structural issue here.

In the USA there will probably shortly be broadband over power lines (broadband over cable and telephone lines apparently isn't enough, I'm waiting for broadband over water pipes). There's still a lot of debate as to frequencies to use, and other matters since the original proposals could interfere with armature and emergency radio as well as some control systems. This could really mess up some mains control systems.

But that's for a house, and for ply on joist construction- not a stressed skin platform. A triscuit is only four feet square and is a directional device: it needs to be supported along the edges (perpendicular to the plywood grain) so that the "joists" and the plywood grain run between the supports. The triscuit will fail if installed at 90 degrees to the proper orientation (most framing members won't be supported) but the combined strength of the plywood grain laminated to both sides of the parallel "joists" creates a very strong structure. Yale style triscuits have been in regular use for more than 10 years and have proven able to support considerable loads without any sign of bowing. The structures supporting them might not be so strong, but that's a different story.... -Michael Feinberg, CTS (Yale Undergrad, 2001) ------------------------------ Message-ID: <001001c4e799$0dffb190$0200a8c0 [at] D4D3R151> From: "Randy Whitcomb" References: Subject: Re: "at LEAST an ATF permit" Date: Tue, 21 Dec 2004 13:10:01 -0700 One more thing to worry about.

I dunno what the mic was doing up without talent being informed beforehand. Most of my mic 'accidents' have been talent related, and fortunately, there have been few. If the guy is supposed to make an entrance, and refuses to co-operate with when and how his mic is going to go up, I'll simply warn him that at such-and-such a time he'l be hot and he can enter as he pleases (mind you, most theatrical environments don't have these problems). If he prefers to start with "Oh shit, I hope they buy this crap!" instead of entering in silence, there ain't much you can do. >There's more going on here than simply a mic being left on by the >performer. I prefer that the mic be left alone by the performer. Switches and such are the responsibility of the sound crew. It should always be such.

It works great and with DMX spec cable there are no problems. Although you think there is no practical way to get the signal from the booth to FOH the solution is fairly simple and may be easily doable depending on the type of cable you have existing in your installation. The way you do this is by making what ETC techs call an "out and back". You do this by using a 2 pair DMX cable. Start with pair A at FOH and terminate normally leaving pair B unused and un-terminated. 1- shield 2-black 3-red 4-unused 5-unused Pair B black and white unused At your dimmer rack leave pair B unused and un-terminated. We will come back to pair A in a minute. At the booth wall plate terminate both pair A and pair B together in pins 1,2 , and 3 of a 5 pin XLR. The wiring will look as follows or similar as colors may vary by cable brand. 1- shield, shield 2-black, black 3-red, white 4-unused 5-unused At the dimmer rack solder pair A from FOH and Pair A from the booth together. Shield to shield, black to black, red to red. Don't forget to heatshrink all of the bare connections. Take pair B from the booth and connect it to your dimmer rack. Shield to ground, black to data - and white to data +. This pair could also be terminated in a wall plate as well. To do this the cable should be Belden 9729 (or equivalent) and not exceed 1200' counting all legs of the data path including the legs out and back. This would eliminate the need for having to plug and unplug at the dimmer, just make sure you only have one console plugged in at anytime. I hope this helps make your life easier.

When I installed our new (used) Dimming system, I installed an XLR-5 connector on the cabinet, and runs of control cable to the projection / spot booth and to FOH. I currently plug in whichever cable I need. I'm wondering whether they could both be hard wired into the cabinet or would the unused cable run cause "Termination" problems. I know that the downstream end of a DMX run needs to be terminated - what about the Upstream end? It's a Colortran ENR system if that makes a difference.

I agree that if you have the frosted side of the plexi up, and it has been frosted by sanding it, you will probably have big problems with keeping it clean. You might consider frosting the floor with spray on frost, available at craft stores. It may get a little smeared with traffic, but won't have the rough texture of a sanded surface. ===== June Abernathy IATSE #321 (Tampa, FL) FOH Electrician The Lion King National Tour (Gazelle) __________________________________ Do you Yahoo!?
