Does this laser module come with its own internal driver, or do I need to buy or build one to power it with two AA batteries?
Thanks!
Thanks!
I'm going to be using this as a pointer in a Nerf gun, so I don't need something that's really powerful, but what power would the complete pointer be?I'm curious as to why you want a low powered module rather than a complete Pointer at couple dollars more?
well your average eBay pen is usually quite a bit overspec,going by my collection, average at least 40 mW in green, 45mW in violet and 70 mW in red ....but can go up to twice that on some of them .i do believe i got a good batch as nearly all of them came from the same seller so i bought more ...but you need to be really careful that's enough power to need goggles if your using it as a toy and pointing it at ppl( which is a really bad idea anyway pointing at ppl ) they need goggles as well all of them, most important.I'm going to be using this as a pointer in a Nerf gun, so I don't need something that's really powerful, but what power would the complete pointer be?
