Perhaps you should use a low powered IR diode instead of the red.It would be little bit more dangerous to put together if you dont have a lot of experience, but would make for a more "stealthy" trip wire.
Re: FS: <600mW 445nm Dorcy Jr. PRICE REDUCED
If you cant sell the complete laser, I may be interested in buying the dorcy host, heatsink, and flexdrive.
Hey, idk if youre not getting my PM's or im not getting yours but i have been messaging you and i havent heard from you in a week. If youre not interested in our deal anymore then please let me know so i can try to find someone else who will sell it to me.
