Facelesstech published a new build:

So some time last year I ordered one of those servo 2 axes (pan and tilt torret) arm kits from aliexpress. It was fun to play with but I didn’t quite find a reason to use it in a project. Then I seen this project on hackaday and a light bulb went off in my head, Why hadn’t I thought about adding a laser to the arm. This would be great to let your cat or dog play with or drive them mad.
