    Since there is no remote trigger available on a HS20 projector, I thought I had it sorted, there is a usb connection on the back of the HS20. I can use the outer pins of the usb connector since they are 5v and ground connections to trigger my screen.

    But no :thumbsdow the projector doesn't supply power on those pins. Does anyone have any other ideas to get a remote trigger out of this beast ???

    The only other idea I have is using half a opto-coupler to pick up when the LED's light up to trigger my screen, but that will look messy, so any ideas ???

    Please...

    Wookie man, I take it from your previous ideas that you are up to speed with electronics. If so, I would recommend a pickup coil around the mains lead connected to a comparator so that when the current through the cable increases considerably (ie the lamp starts to draw current), it will be sensed by the coil and switch on the comparator. I think something like this may even be commercially available. Hope this helps, K

    Hi there!

    A Swedish manufacturer now has a really easy install product called "AutoLink". It is plugged into the projector's power input and sends an IR signal to the screen when power is turned on... :thumbsup:
