The easiest poor man's way would simply be to take a simple trigger that works off a circuit closing. Remove the switch, wire up a bunch of additional switches in series and the circuit won't be completed unless all switches are pressed. It requires some manual work, but is probably the absolute cheapest way you could accomplish the goal.

Both units do what it says on the tin. For simple triggering, the Yongnuos are (generally) cheaper and as reliable as the Cactus units. But there are differences between them that may be important, depending on how you plan to use them. I use the V5s because of some of the additional features they offer.
The Cactus V5 has an external rotating channel ...

So, having looked for some for a while, I'm going to have to sadly put forth "No" as the answer here. The TTL features of the radio triggers are relatively new, and their makers have (reasonably enough from a business point of view) gone with the market dominators first.
Hopefully, they keep hearing enough from Pentax users that they'll consider the smaller ...

Sounds like you want optical slaves. Use your on camera flash as normal. Put those on the off camera flash and they'll fire when triggered by the main flash.
Note - some flash units have this capability built in.

The hotshoe on the transmitter is a pass-through connection; all you need to do is mount a flash (or a flash cable) on top of the unit you have in your camera's hotshoe. Note, though, that there is no TTL for the pass-through function either, so both flashes (the off-camera and on-camera flashes) need to be adjusted manually and separately for the lighting ...

The sync speed itself doesn't change, as that is defined by how quickly the shutter curtains move, but what is happening is the trigger is adding a delay, which throws off the timing. What ought to happen at 1/200s is that the first curtain reaches the top, the flash fires, then the second curtain starts closing immediately from the bottom. However due to ...

Well. the max sync speed presupposes that the slave flash reacts instantly to the trigger. If it takes any amount of time at all for the slave to react, that is going to eat into your sync speed as the second curtain will have started to close before the slave flash actually fires.
So I'd say that yes, you would be better off to back off some from max sync ...

I could be wrong, but garage door openers work on RF and not IR and they have to be configured to work with your garage door (they won't work with any garage door out of the box). Similarly, while the IR beam may be the same, different cameras may respond to them differently or require different patterns to operate. I'm not too savvy on IR spec's, but I see ...

I use this: http://amzn.com/B002W3IXZW from cowboy studio or if you have more money I would get this: http://amzn.com/B00BBQ8IDS from Pocketwizard which was just released. Many people also praise the inexpensive Yongnuo transmitter/triggers.
The 60D even has a built in wireless transmitter. The 60D's built-in flash can act as a controller or commander to ...

I use the Camera Axe (http://www.cameraaxe.com) with great success. Its an open source project that's been around for a while and has a fairly large user and support base.
The device has four phono plugs which can each be configured as an input or output trigger. Simply connecting a wireless device (e.g. PocketWizard) to these ports will let you trigger a ...

This is what I found on page 177 in the manual for Canon 60D:
While this certainly works with the Canon's radio remote, I have not actually tested it with the Yongnuo. My guess is, the signal from the trigger simulates the 'immediate shooting' signal emitted by Canon's own triggers, and that's why you are only able to shoot stills with it.
As far as I ...

This may sound silly..but are you sure its rotated the correct way? It doesn't look like the flash shoe would prevent it from this angle and any of those four pins resting on the ground plate could cause funky things for sure.
If not...
While I can't say for sure, part of your problem could be this (although I can't imagine why it would be causing rapid ...

Have a look at the Amazon "Product Description" more closely, the trigger is hotshoe mounted, so it will work without the need for the sync cable. In any event, if you don't want to get that one, the Cactus triggers work as well. I use those with my K-5 and Alien Bees and have never had a problem (nor had to use the PC cable, though the K-5 can use one).

This radio trigger appears to support P-TTL and high-speed sync.

No, they're not compatible. See the website: http://www.phottix.com/en/studio-accessories/phottix-atlas-ii-2-4ghz-wireless-trigger.html for details, it's stated very early in the product description. In fact, it says it 4 times in the page, so I'm guessing they get this question a lot...

In addition to a radio trigger, you might consider an off camera shoe cord. They come in lengths from 1.5' to 10'. They are a very economical option for getting the flash off camera while still retaining TTL capability. This shot was taken using an off shoe cord in a dimly lit banquet hall. I hand held the flash with my left hand about 18-24" away from the ...

This Canon site article:
http://www.learn.usa.canon.com/resources/articles/2012/eos6d_builtin_flash_alternative.shtml
discussed a nice alternative--a 90ex speedlight which can act as a Master unit with a 430exII as a slave. I have just ordered one to use with my Canon 6D and will see if it works as indicated. I also like that it is quite small, and can ...

The product description on the page you link to states that it is 433 MHz, so it is radio (RF), not IR.

for prevent vibration when taking photos under long exposures,
close-ups (macro) or continuous shooting. It can instantly trigger the

The product on Amazon appears to use radio of some sort, probably RF as there's an aerial.
For long bulb exposures I wouldn't use a radio trigger as your relying on the battery and signal for a long time. I'd go with a wired release.
You have the option to use the Nikon MC-DC2 (listed as compatible with the D5100) or any one of the far cheaper copies. ...

I'm confident that it doesn't matter. The sync max speed on your camera is when the shutter is completely open. A flash is typically 1/2000th or less. Delaying it a few milliseconds is not a problem.
None of this stuff is "exact" timing.
Many of the wireless trigger systems use two channels, one for the shutter and the second, a "relay" for the strobes, as ...

Almost all wireless triggers I am aware of work with hot shoes.
Phottix: Atlas, Strato
Pocket Wizard
Cactus
Yongnuo - RF-602, RF-603
RadioPopper JrX
I know some of these (Phottix, Yongnuo) are compatible with Pentax, but you'd need to research each model to be sure.

You can checks whether it's a pin issue by connecting only the two pins that matter: center pin and hot-shoe side on the flash and with the two contact parts on the receiver hot-shoe. (Two simple wires should suffice, you can use duct tape or ask someone else to hold it while you try the wireless trigger.)
If this works, you then just need to cover the ...

The PDF review mentioned on the same site (http://www.alphapics.co.nz/Pages/Pixel%20Knight%20TR-332.pdf) lists the 350 on the Compatible list. Sorry I can't answer your question more directly (I'd add this as a comment instead of an answer if I had enough reputation yet)

The answer is: no, this won't work.
But it's not because Sony actively is blocking the flash from working. It's just that Nikon's wireless TTL system (which they call "CLS" — Creative Lighting System) isn't compatible with Sony's wireless TTL protocol, which they call "WL" (presumably for WireLess). The concept is the same — a measurement preflash, and then ...

Many cameras have an optical wireless remote release sensor. An optical remote is just a couple of $$'s (like this example) and requires no special receiver to be attached to the camera. Of course, you generally need line of sight to the camera, or at least a good reflection from nearby walls or ceiling.

I think you can find some good responses here: http://strobist.blogspot.com/2008/11/cyber-commander-launched-flash-remotes.html
I have not tried the commander, but I own the cybersync transmitters, and love them. Never had a misfire. The only problem is that they can toggle on while in a bag, and run out of juice.
