I have been seeing different designs for this device for a couple of years now. What I really need is a device that can trigger a regular digital camera under computer control. The DSLR's have the capability, but all digital cameras should be equiped for this capability. All it would take is some software to the USB port and we could do a lot more with the cameras than just take pictures. I need several to collect specific image data at specific events. I am not sure this one will solve my problem, but I will keep an eye on it as it comes to market.
