    Venue Spot Booth Guard rails

    I've rendered the venue in ETC's Augment3d using the currently-at-60% paperwork, and there are issues we'll be speaking with the architects about, in regards to sightlines. As for OSHA requirements, tensioned wire rope will meet their requirements for guard rails in a non-public space. I...

    Conventional Fixtures Altman 1000 followspot operation/questions

    If it's an FEL source, leaving it burning is just using up lamp hours. Shut it down whenever prudent - like, if it's not going to be used in the next 10 minutes or so. Less, if the on/off cycles aren't going to be distracting for nearby patrons.The "leave it on" mentality doesn't typically...

    Venue Spot Booth Guard rails

    To answer some of the question above, and to add a bit more detail - It's a sub-900 soft seated venue, with the spot booth suspended in the catwalks some 10' to 15' above the balcony seating. Throw distance from the booth to the apron is going to be approximately 70', and the spots are, for the...

    Venue Spot Booth Guard rails

    I've already had calls like that. Nobody came to push me off, no matter how much I begged.That said, "*waist belt", I believe.

    Venue Spot Booth Guard rails

    Those ANSI references are excellent links, thank you.My end goal here is to have a follow spot position which doesn't require operators in PPE, i.e. a permanent work platform with adequate guard rail and edge protection, and which has minimal visual obstructions. Think "Wire Rope Grid", but...

    Venue Spot Booth Guard rails

    Hey all -We're in the design phase of a new venue, and we're looking at engineered, permanent travel restraint in the spot booth, for its beam-side. The architects are currently suggesting a guard rail system (in front of the spots!) which will have obvious shadowing issues when trying to...

    Red Dot Scope for Followspots

    We have a Telrads on our two Lycian M2s. We have a couple of the 2" standoff mounts available for our spot ops to use as they prefer, as they're easy to add and remove. They work a treat. The rings correspond (in our space) to a headshot, head-to-waist, and full body shot. The standoffs do add...

    Control/Dimming Pulling DMX from 4 Pin lines

    Some gear (specific brands elude me off the top of my head) use pins 1 and 4 for an electrical circuit, and the shield is dropped from the data end of things. It means the DMX isn't really DMX any more, as the data+ and data- make do with a sort of floating reference for the units - it's...

    Light Trees with Floor Flange vs Base Plate

    We have some older floor plates here with flanges - they're heavy, solid 2-layers-of-1" ply bases, about 30" on a side, and the flanges are bolted on (there are 6" square plywood 'feet' [pads?] on each corner underneath to allow for the bolts and washers needed for this). We pile stageweights on...

    Naked in the box

    Sooooo many jokes possible here. "Do not disconnect under load" is my current favourite.

    How many hours does a lamp lose on every strike?

    I believe DMX has 256 steps over that 100% range - maybe this is just semantic, but I think 2.5:1 doesn't quite make it to a 'far greater' ratio. But yes, it's better than 100 steps to full, which I think was your point.As for your pre- and post-warm levels, I'm not sure how much lamp life...

    Naked in the box

    Incidents of unwanted booth visits during shows by bored, distracting, and noisy rabble dropped dramatically after I made it clear that my booth was "Pants-Optional." Not that I'd take -mine- off. It's hella cold in there. But perhaps knowing that they had a choice to make before entering was...

    Busking on an Ion?

    The updates add enough functionality for a busking show that it's worthwhile asking (pleading, begging - cry if you have to, if it might work) them to do an upgrade, even if they choose to retrograde after the show. It's a process which is just as easy as upgrading.For me, the jump to 2.5.x...

    Cleaning Routine for Movers?

    I've found snowflakes and confetti in mine. It's almost like those fans suck! You've really got to watch out for the shiny Mylar-type confetti - it can short out electrical components if you're unlucky.

    Looking for a low-cost ocean waves effect.

    If you cut it into strips, attach the ends of the strips flat at one end, loosely twist each and attach the other ends - like in a frame of some kind - so there's a little play, then blow a fan gently along the strips, the effect may be close to what you'd like.You may need to fiddle with...
