Hi everyone! Another lovely red laser project for you any questions or comments you know where to put them. Apologies for the long posting times I decided to have a small break whilst I settle in to my new London flat. Lots of plans for more videos but if there's anything you need to me cover let me know!


Remember lasers are dangerous, they are NOT toys! Never point lasers at any living thing / moving vehicles! Be sensible and responsible when using lasers!
