i saw 2 of the same of these but one had a longer description

Thanks Hammer...I deleted my previous post...it was bad form for me to post links.

My intent was just to say thanks and give props for a handy little MC. I especially like that you took the time to label everything...makes hook up a snap even for those less logic savvy like me.

Thanks very much for the kind words and add to your projects @Megahurts - Your work is fantastic.

How does this work?

I have been trying to make this myself unsuccessfully. I'm grateful that you were able to. However, I must point out that the flashing light violates Rule 36 of the US regulations for International Waters "Any light to attract the attention of another vessel shall be such that it cannot be mistaken for any aid to navigation." While it can be used for Inland waterways per Rule 37, it is a signal for distress rather than navigation in low visibility. Even so, thank you for making this.

details pls
