RF Remote
My camera/flash project circuit is coming together. Now, the next issue,
since I dont want to have 20 foot long wires running between the camera, project circuit, and flash units, are there easy to use, RF transmetter/reciever on a chip, type devices. The range only needs to be about 50 feet. (The inside of a photo studio.) Hopefully, this will be my last annoying question. Henry |

Henry If you're talking about having a bunch of flashes flash simultaneously, have you looked into "slave flash" devices? They have a photocell of some kind, pointed at the "master", that sense the flash, and flash their own flash unit based on that. You wouldn't have the opportunity to do a big electronics project, but you could get your pictures taken. :-) Good Luck! Rich |

But they are still about $25 each (more for the more sensative ones), they are still line-of-site, so if they are not pointed correctly they dont aways "see" the master flash. They also have limited range (of about 10-15 feet in my experiance) and are basically good only for an indoor, close in portrait, studio setup. But they have littel use for something like outdoor or arcitectual photography (where a flash unit might be around a corner, or behind a column. Plus all the cords snaking all over the place are a trip hazzard and take more time to setup. With the information people have answered here it looks like I may be able to build my own RF flash trigger T/R set for about $40. That is about 1/3 to 1/4 the price of commercial units. Henry |
