I've been successfully using DSLR Shutter to drive my Pentax K100D shutter through the parallel port of my old lappie. I finally put a small relay into the cable to operate the shutter by having the pin voltage change at one of the parallel port pins driving the relay coil and closing/opening a set of contacts.
Now I want to move DSLR shutter to my new little el-cheapo Acer, but no more parallel ports, nor serial ports, just USB 2.0.
I want the cheap solution. (Shoestring DSUSB??? huh? Keyspan connectors - Huh? Sounds like spending money to me.)
I can spend time researching or just ask here and see if anyone takes pity on me and advises
So, to my uneducated brain, the way I see it is that I must be able to make DSLR Shutter talk to one of the USB ports - true? If so, I must be able to get one of the pins going up and down as DSLR Shutter does its stuff - true? If so, I should be able to take that signal to my little relay's coils and I'm up and running!
Grateful for anyone to set me straight here.
Thanks
Eric
