I want a wireless cable release! Who can build one?

Since the original Graflite flashbulb holder was designed to work with lens board solenoids, why not use those items?

It seems to me all you would need to do is remotely trigger the lens board solenoid. The Graflite has at least one "H" female socket for remote triggering. So all one would need to add is a radio strobe synch set such as ones from PocketWizard or Paul Buff CyberSync. Add a flash cable from the receiver with an "H" male plug on the other end.

In my case I already own a Graflite flashbulb holder as well as a CyberSync kit and several PocketWizards. So it seems like all I will need to add is a cable to link a receiver to the Graflite.

Set the shutter to "T" and one pulse to open the shutter and a second to close it and you have your photo. True, there is no timer involved but I've found with long exposures on B&W film, close is good enough. A cell phone app or stopwatch can provide the duration, if needed.

The nice thing is a flashbulb can be added for fill, if needed. They are still made at a factory in Ireland by Meggaflash: http://www.meggaflash.com/

Question: do I have to worry about energy from the Graflite batteries going back to the radio receiver? If so, how do I isolate it? Or should I add a small relay between the receiver and the Graflite?

Cool app.
Not wireless.
They don't make a cable for mechanical shutters.

I was thinking about such a device earlier today, when I was trying a self-portrait and needed a four second exposure (paper negative). I remember years ago the air bulb shutter releases that used to be in those small ads in AP. Still available, it turns out, from the auction site - here. Now if treading on the bulb up to 20 feet from the camera isn't good enough, it would surely resolve some of the risks of shutter damage from too much force or too great a travel to have the wireless device just compress the bulb. As for longer exposures - use T instead of B and count without moving your lips! Just a thought....

I'm going to pretend you read the thread and aren't the first person to suggest these horrible devices. Have one. Garbage. NOT WIRELESS.

Thank you for your courteous reply, kind sir.

Hmm, the tip of the air release, plus http://en.wikipedia.org/wiki/Lego_pneumatics then it's just a case of a servo and Bluetooth arduino could be the solution. - Now it's just figuring the control mechanism and components - could be do-able I reckon.

At the risk of beating the topic to death, there is a new-to-me Instructable here. Scroll down to readers' contributions for a latching-solenoid version.

A question regarding the Graflite flashbulb holder and shutter solenoid: there is a remote/slave plug on the unit. Is a slave sensitive enough to infrared to use ordinary IR remotes? (The solenoid is not a latching type which might be problematic for long exposures.)
