So I had this 5mw green laser lying around and I had the idea to build it into a LEGO power functions motor housing so I could use it with the lego PF system & an Sbrick in MOC's.
A few days of figuring out how to do this... and then I just build it!

It works perfectly, and it's super cool to see! ti is very bright, the beam is just visible in daylight (hard to take a picture of unfortunately) and pretty well in the dark. In the video it's completely invisible though due to the video lights.

I thought I'd post it, see what you guys think, hopefully Inspire some people to think outside the brick!

I've had it finished for a while now and it has already been built into one of my MOC's: The Terraformer
   • The Terraformer    17 PF motors, 5 SB...  

I also recently made a LEGO power functions electromagnet:
