It’s still around but it was moved to the old SGI building in the SF/Bay Area. I went to the old one growing up; my dad worked at DEC and it was great fun to see all the hardware at the CHM.
I have a sky camera (use it for weather and sky observations; my airspace is a bit busy for easy meteor observations). So far my sensor seems to be fine despite an unblinking gaze upwards.
I didn’t use a security camera; I built a sky camera. It has a 140 degree fisheye lens with a Pi HQ camera (I might replace the camera). Built a waterproof case and it’s been living on my roof. It recorded the aurora over the SF/Bay Area. Not super spectacular but I was exited. https://youtube.com/watch?v=Pkks7PWzpSM
It’s another Half-Life reference
