Never ever miss a shot with the LAZER laser pointer for your NERF gun !!!
LAZER is a basic but efficient light point projector that use a cheap 25 mm diameter 8x plastic magnifyer lens, a green 3 mm and an high intenity LED.
Lens taken from :
I think other lens like one used in cheap basic monocle should work (~3$ Amazon)
The angle of the pointer is adjustable. The screw is optional and help adjustment procision and stiffness of the assembly. The use of my CR2032 light cartridge is requierd.
The reason behind this project :
My son and his friend ask me for a laser pointer option to put on his NERF Modulus. Both FDA and OAA recommend to keep laser pointer out of the reach of children. There is a theoriticaly acceptable "safe" power limit for laser pointer, but many test show laser pointer with more real effective power than the specs show. Give a kid a real laser pointer is not a safe option.
This is the reason why the NERF pointer available on the market is not a laser pointer, but a "light ray". So, i drop my first idea to simply print an available 3d printable laser holder here, and design my own mini light spot projector.
