hey /diy/
also, i'm looking for a simple circuit consisting of a laser diode, photodetector (like a photosensitive resistor) and maybe an op amp comparative. The purpose is that i could print it out in a pcb and then place it in-line between an appliance and wall power. when light from the laser stops hitting the photodetecting element, the PCB acts as a shut-off switch for the appliance, shunting power from the wall straight to ground.
i know basic circuit design but not much else, any pointers?
anyone know of any circuit schematics i could use for reference?

This is going to shut off the appliance and everything else on the same breaker.

Why not use a Triac instead of shunting your power to ground? What is the end goal here. The triac would allow you to control the 120v with a 5v interface.

What appliance? A SSR could work.

>it's either a Zaber linear or rotational stage
Does Zaber really not offer a better way to turn their stuff off than yanking the cord out of the way?

Is this for some fail safe?
I don't see why you would need to do this for a $10,000 linear stage that has it's own controller.
