Thanks. Can you tell me the mW of the lasers you used in the 7 color laser build? I didn't get the ones from the guide as the links weren't the bets but I got some off eBay and they are 5mW Red, 5mW Green, and 45mW Violet. The dot of the green and violet are really big compared to the red dot and I was wondering if after I put them in the bras fitting if the 3mm hole would help all the beams be the same size. Thanks, Nick.
