->> I have a group on flickr and someone posted this question. I don't have an answer but figured if anyone would it would be this crew:
----------
Does anyone know of a piece of gear that would allow me to shoot sequentially from a bank of strobes?
I'm needing to fire multiple times per second which is cooking my white lightnings, even on minimum power (which is not strong enough). I have Einstein 640's on order, but even these will need to be in a bank of 2 or 3.
I have a bit of electronics somebody made for me into which you can plug up to 8 strobes then fire them all at once, or one after the other on a one strobe per shot basis.
It's more than a bit flaky and getting a redesign is highly unlikely. I've had a good search online to look for some commercial gear that would do this without joy - does anyone know of anything that would do this?

Here is why he needs this ability:

Hi Peter, not a SportsShooter member but happy for you to ask on my behalf there.
I look after the photography solutions for a company that runs a luge cart attraction at several sites around the world. I'm rebuilding the system used as the existing doesn't handle flash well at all (the homemade circuit board I was referring to). The part of the system I want to use these on is automated photos of people coming down the tracks on the carts (D90 using a laser tripwire to trigger). The tracks can be very heavily used (the Singapore site gets over 1 million people through per year) with clusters of people coming through at a rate of up to 3 or 4 per second in bursts, 1000 per hour in peak times, hence the need to spread the load over several strobes.

Any thoughts? You could reply here for the benefit of everyone here or directly to the thread

| ->> PW MulitMax speedcycle function will accomplish this, but it's expensive (you'd have to have at least 5 MMs) and it appears that your max number of strobes is four. |

->> I found this article where they achieved 40 fps with strobes - but it was with 4 cameras.

It was linked from the Strobist website. http://strobist.blogspot.com/
I would search that website for more information, especially its Discussion Threads.

Hey Peter, his next question costs him $25.
SB-800 has the "RPT" Mode. A bank of them could be placed on PW's. |

| ->> I Would second the Mult-Max route, I use that set up for events with 3-4 set of lights when I need fast recycles. And Matt is Correct the max on the standard Multi Max set up is 4. And LPA Design's Wave Sensor is a good triggering device with a laser sensor or sound used to fire a camera. It's a good product as well, can you tell I'm a fan of LPA. |

->> I would use MM's speedcycled, with a bank of lights connected to each MM via a splitter. This gives you a few advantages
First, the power is distributed to multiple lights per exposure. instead of one light at say 300ws going off every 4 seconds (say 1 light per bank, 4 banks cycling every second...), you can have 2 lights at 150, 3 at 100, 4 at 75, etc. This puts less stress on each light per pop.
Second, with each of the banks holding say 2-4 lights, if one light were to go out, you would still get a shot, perhaps underexposed, but by no more than half a stop.
Also, if each splitter had an extra outlet, you could always plug in a light to replace another without having to take the system offline.
So each Multimax would be its own zone (A,B,C,D), and each zone would have a bank of 2-4 lights say...
I've used a Belkin Rockstar (its an audio splitter) before, and it works, though for something like this, I wonder if you could find or make something a bit more pro.
As for the trigger, That wave sensor sounds great, but another alternative is CameraAxe. It's pretty nifty. |
