Edit: We now have a laser tripwire kickstarter campaign! Check it out here:
I've had a few people ask me lately about how to use an AC wall outlet to safely power a laser as opposed to batteries. I made a short video that shows you how to do it safely. It is a simple and practical video. There are many methods in which to accomplish this. I show you two of them in this video.
Thanks for watching! I hope you find it helpful.
