If your handy with electronics, you could build one with an infrared pulsed LED on the transmitter and an infrared phototransistor on the receiver very easy & cheap. I've never built one or I would send you a working unit schematic. You might even be able to use off the shelf sync slave recievers if they are sensitive to infrared and just build the pulsed infrared LED transmitter. You could even get an old little flashbulb unit with the reflector and aim it at the slave to increase range.. jco

I've been reading (spent a few HOURS at this a couple nights ago) through a website called "strobist" (http://strobist.blogspot.com/2006/02/welcome-to-strobist.html) And it has me quite interested in learning how to work with my flash OFF-camera. As I have a DS, there is no internal wireless trigger. And, quite frankly, I like the idea (as shown quite frequently on this site) of not even having a flash on-camera at all - just a remote trigger. So the idea of purchasing a second EF-500 DG Super just for triggering purposes doesn't appeal. However - the units he recommends are a bit pricey for a pair ($400!) of transceivers. As I'm not sure how I'll progress with this kind of work, I'd like to start out "cheap" and work my way up to the proper gear if it appeals. Does anyone have a recommendation for an inexpensive way to trigger a flash wirelessly? Doesn't have to be TTL or P-TTL or anything - just a plain "standard" hotshoe-mounted device on the camera and a plain old remote hotshoe-connected device on the flash. Would be cool to find something sub-$100 - does such a thing exist? -Charles -- Charles Robinson [EMAIL PROTECTED] Minneapolis, MN http://charles.robinsontwins.org -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net
