Here's a rough overview of how to setup up and automatic bulb ramp time-lapse with the Timelapse+ using USB control of a Canon EOS camera.
Sorry it's a bit rough -- I filmed it with a 7D with the strap tied short and hanging from my neck, so it was a little difficult to see as well as talk while trying to manage the camera. I guess I could use a second tripod!
