Here are two chillers that I've made over the years. My dad and I had originally made one back in 2004 for Romeo and Juliet out of a large Rubbermaid 120 quart tub. There were no fans in it, however the fog moved though it very well since the hose runs were very short and didn't have any...

Yes I meant AMX signal. Original post corrected.

I had a similar problem at the school I work at when we upgraded from a Strand Lightboard M to an ETC Express.We have 9 of the 12 channel packs installed each with a AMX card. The cost to replace all 9 cards with Johnson DMX cards was quite pricey, so we bought a Doug Fleenor DMX-AMX...

The school I work at did Wizzard of Oz (RSC version) last year.We came up with using a video camera and projector for the wizard and it came out awesome.Here are a few pictures.My dad and I made the dowser. One of my crew members just flipped open the shutter at the right time, and...

The science behind carry over cooking doesn't apply to a discharge lamp. The reason food heats up an additional 10-20° is because that measurement is taken in the center of the food. When cooking, the center is always cooler than the outer surface. It is this heat migration from the outer...

Yeah, I kinda wondered about that as well, but the electrician was the one that did that part of the install, and I have no doubt that he knows his stuff, so I never gave it a second thought. I remember his concerns about the fill for the conduit going out to the lighting positions since I...

Don't get me wrong, there are plenty of things wrong with that picture you posted, however, the "office phone junction boxes" are actually DIN rail mount terminal blocks. They are a very common and appropriate method of wire splicing. You can get sizes large enough to handle 4/0 AWG wire...

Not necessarily. The Tone Squelch that AT wireless receivers use will prevent any interference from becoming audible if the receiver isn't receiving the tone from a compatible AT transmitter. From AT's website - If the tone is lost - the transmitter goes out of range, or the signal drops...

Where are you located? What tv stations are nearby? And what is their actual transmitting frequency? What I think is happening is interference from a tv station in your area. I had the same problem as you are having a couple of years ago when I first bought some AT 3000 series systems at...

Any EF mount Canon lens going back to 1987 can be used on any current DSLR with full functionality. Canon introduced the EF mount in 1987 as an upgrade to their previous FD mount which was fully mechanical and had no provisions for auto focus. The EF lenses have the auto focus motor mounted in...

I'm going to dissent with the advice of getting a tripod. The key to blur free pictures in a stage setting is to use a fast shutter speed that freezes actor's motion, as well as camera shake.With the newer DSLR's having such usable high ISO (that in turn will give you a higher shutter speed)...

The GM certainly can be disabled on the Express as I just did it to my 72/144 this past week. The GM was starting to get a little flaky - you'd have to push the fader sideways to get it to register, otherwise it would drop to 0. It started off not too bad - it'd happen once in a great while...

Sorry for the delay on responding with a follow-up, I got hung up with finishing up events at the end of teh school year, and a pretty intense work schedule. What I ended up doing was taking a small 400w DJ fog machine I had sitting around and putting that below the "table" they were using...

Thanks for the suggestions so far. The ring shooter shows some potential promise after some modifications. derekleffew - I originally thought of the smoke in a can, and I just picked up a can of it this afternoon. It doesn't really work for creating a cloud. It comes out to thin and slow...

I am trying to figure out a way to make a small device that will create a safe small mushroom cloud of smoke. The device can be hidden in a cauldron. I know that flash pots are out of the question since it happens so close to actors. The show we are doing is "Once Upon A Mattress". Near the...
