Step 1: Components Needed
• two cell batteries
• a lot of electrical tape
• a 5mw laser diode with two wires pre-soldered to the laser diode
Step 2: Putting It Together
You need to blu tac the two cell batteries together by putting a bit of blu tac on the edge of the area where the two batteries meet and then squeeze them together and make sure that they are securely together and that there is a bit sticking out so that you can connect the
Laser diode to it by placing it in the blu tac and than wrapping the wires around to the two sides of the new larger over all battery and then place a piece of electrical tape around the whole thing and make sure it is keeping the plastic down and not the conductive metal.
Then you have to add some more pieces of tape to make sure that it will stay together and that it will not look ugly.
