Topic: Safety Hardware

[vinietje]

Hi,


I'm looking into building some safety hardware in my diy projector setup
- (pt-20k) galvo+amp
- pt-trust showcard (only for the ILDA interface)


i noticed there is some header on the driver, which may enable me to tap into the feedback circuit of the amp.


I'm hoping to sample this signal with a uC controller, to switch the laser whenever the mirror is sitting still at some point for X time.


Has someone got any experience/thoughts regarding diy safety circuitry?


I'm afraid at some point one of my galvo's or the pc-app will crash, and my beam will be still but on

That's an interesting idea.

I think there might be something out there.
