Line laser pointer and normal laser pointer

I'm Creating a Custom Laser Pointer with eBay Modules. Here's How I Did It. To build my custom laser pointer, I acquired two separate housings - one for a line laser module and another for a regular laser module. The modules themselves can be sourced from eBay at these links: http://www.ebay.com/itm/Red-Line-Laser-Module-5mW-650nm-Focus-Adjustable-Laser-Head-5V-/181955353142?hash=item2a5d625a36:g:v~MAAOSwNphWZsaK and http://www.ebay.com/itm/Mini-650nm-6mm-3V-5mW-Laser-Dot-Diode-Module-Red-/272058069247?hash=item3f57ecb0ff:g:BXEAAOSwuTxWCl70. The batteries I used are of the type AG13, which provide enough power for my setup. Assembly: To assemble this laser pointer, you'll need three PCBs. Two of these boards feature a 3x3 grid pattern with a single pin at the center. Remove any insulation from the pin and bend it downward for easier handling. These two PCBs are responsible for connecting the batteries (refer to the images). A small hole in each battery slot allows you to connect the cable to the back of the batteries. The other PCB is simply used for the switch, while the triangular holes in the battery slots ensure that removing the batteries remains a hassle-free process. Notably, the line laser module requires more power than its counterpart, necessitating three batteries for operation and two for the regular laser module.
