    Problem with Dimmers 'pulsating'

    I've had some older, heavily used LP-624s start to have intermittant fader issues, either shorting to full-on or full-off as the fader is moved, but they tend to affect output ONLY when a finger is on the fader knob, and only individual channels. Continual pulsating after you've stepped away...

    Building a lighting inventory- baby steps

    Regarding LED vs. conventionals, this situation is kind of made for going LED. Not in terms of power usage, heat, or anything like that, but because you don't already have a large inventory of dimmers and lights. A high dollar LED fixture seems pricey as a single unit, but when you consider it...

    Control/Dimming Leprecon mx1200 dimmers vibrating/buzzing

    The MX series first came out in the late 90's, so your dimmers are about 15 years old at most.There are no transformers of any significant size inside, so delaminating plates isn't a worry. I haven't heard of any troubles with the chokes, either. The fans, however, are a common failure, and...

    Church wants to Baptize in my theater

    A few thoughts, even though the situation is already resolved -Condensation will only occur when the water is colder than the air temperature. If the tub is heated, or at least filled with warm water, condensation should be negligible. A tank of cold water sitting directly on a floor...

    Physics of theatrical fog/haze?

    Air temperature and humidity can also have a bearing on haze hang time. The more variables you can control, the more predictable your results are going to be.Strategically placed fans (or ceiling fans) can help distribute the haze evenly. From what you've said above, it sounds like your best...

    Platforms with Marquee Lights?

    I've done a lot of marquee chasers for scenery using christmas light socket strings, Christmas Lights : Rope Light : LED Christmas Lighting : Novelty Lights Inc is one good source. Using premade strings will save you hours and hours of wiring.For exposed bulbs I've found that beltsanding an...

    Bad Install...

    Yes, it does....Inside that length of stovepipe is sand and cast iron window sash weights. I wrote a report in 1993 or 1994 telling the guys who ran this theater to remove it immediately - I was finally called in to remove it this past January, when they noticed the ropes were finally...

    French Windows for Peter Pan

    If you were putting plexiglass in the window, and seeing the thickness of the muntions/mullions wasn't a priority, simply doing them with tape or paint lines on the plexi would be an option.However, 4' wide x 12' tall window halves would be rather flimsy if all they had for framing was the...

    Electrical Box Spark Effect

    I'd second the glitter-puff idea, with some strong cross light narrowly focused on the glitter, to make sure it 'pops' visually. Mylar confetti can be used as well.Another thought would be a few dimmer's worth of jagged spark gobos fast chasing on the wall around where the bit is taking...

    Intellabeam 700HX Sparks Flying

    My memory of working on these units years ago is that temps inside the body near the ballast tend to get warmer than PVC electrical tape is likely to stand up to, you'd run the risk of the tape melting/burning during longer shows. Come to think of it, one of the more common failures of the...

    Dressing Cable Outdoors?

    U-Line and other packaging suppliers sells clear plastic sleeving that's handy for weather proofing connectors. I typically tape the uphill end, and leave the downhill end open to drain, otherwise I have seen the sleeves fill with water that creeps in under the tape. Also, I've seen connectors...

    Large ping pong balls

    A ball painted white probably wouldn't pass light from the inside, the paint would be too opaque.Perhaps some small Chinese paper lanterns? Just make sure you pay attention to flameproofing.

    Drafting a Compound Rake

    I think what you have is less a compound rake than it is a irregular shape with a simple rake.If it's truly a flat surface at the plywood skin, then you could put another sheet of ply on it, slide it down until it touches the deck, and see that it's a single slope. What I'm imagining from...

    Little Giant Cage?

    I've learned over the years that there's no reason to be afraid of heights. Depths, however, do command a certain amount of respect.
